對天乙社區bbscs8實現的詳細分析二

此文爲轉載：http://www.diybl.com/course/1_web/webjs/2007113/82989.html


我們回到正題上,除了logger,還有boardDAO(當然要了)
,userGroupDAO,boardPermissionDAO(講過的),permissionDAO,roleDAO,forumDAO,forumHistoryDAO,還有一些Cache服務:sysListObjCache,boardCache,userPermissionCache(以前用過),還有一個額外的服務類:sysStatService;對他們進行getter/setter方法一下...
我們分析下sysStatService:(applicationContext.xml) 系統統計服務
 //每次請求都產生一個對象

userConfig指:
${bbscs.safePath} //安全目錄我的指的是D:/safe/


UserConfig是一個config配置服務,在服務類中首先注入了safePath 這個String對象,它向外提供了String getUserFilePath(String userID)[簡單,最終得到一個用戶文件Path,見實際目錄就可知道其原理]和String getIndexPath()和File getIndexFilePath()以及boolean indexExist()四個對外公共方法.詳細看方法實現:
public String getIndexPath() {     //好象沒用到過
StringBuffer sb = new StringBuffer();
sb.append(this.getSafePath());
sb.append("index/");
return sb.toString();
}
public File getIndexFilePath() {
File indexFilePath = new File(this.getIndexPath());//構造一個File對象
if (!indexFilePath.exists()) {
   indexFilePath.mkdirs();
}
return indexFilePath;
}
public boolean indexExist() {
File file = new File(this.getIndexPath() + "segments");
return file.exists();//使用文件是否存在的方法作判斷!
}
可見config服務類較簡單(沒用到logger)!提供一個常用服務!而com.laoer.bbscs.service.imp.SysStatService是怎麼用到它的呢?它繼承了抽象類SysStatService,在這個抽象類中,有一個東西是私有的:
private long onlineNum = 0;
private long appearTime = 0; 發表時間long類型
private String appearTimeStr = "";
private long allUserNum = 0;
private String lastRegUser = "";
private long postMainNum = 0;
private long postNum = 0;
(這個東西和safe文件夾下的sysstat.properties好像啊,看看先:

#sysstat.properties
#Mon Jul 16 11:35:16 CST 2007   //appearTimeStr ??
onlineNum=2
postMainNum=1
allUserNum=2
appearTime=963209825828
postNum=1
lastRegUser=sgwood

)下面有其get/set方法,子類可以繼承哦!當然,還有一個子類需實現的方法:
public abstract void load();
public abstract void saveOnline(long nowonlinenum);//在線數
public abstract void saveAllUserNum(long allusernum, String lastreguser);//所有用戶數和最後註冊用戶名
public abstract void savePostNum(long main, long all); //存入主題貼和總數
接着我們看下SysStatServiceImp.java文件好了:它加入了logger和UserConfig對象先,看下面的load方法:

public void load() {
Properties prop = new Properties();
File f = new File(this.getUserConfig().getSafePath() + "sysstat.properties"); //getSafePath()當然會暴露出來!
if (f.exists()) {
   try {
    FileInputStream fis = new FileInputStream(f);
    prop.load(fis);
/**只需傳遞這個文件的 InputStream 給 load() 方法，就會將每一個鍵-值對添加到 Properties 實例中。然後用 list() 列出所有屬性或者用 getProperty() 獲取單獨的屬性。 
list() 方法的輸出中鍵-值對的順序與它們在輸入文件中的順序不一樣。 Properties 類在一個散列表（hashtable，事實上是一個 Hashtable 子類）中儲存一組鍵-值對，所以不能保證順序。
*/
    this.setOnlineNum(Long.parseLong(prop.getProperty("onlineNum", "0").trim()));//繼承過來的!!!
    this.setAppearTime(Long.parseLong(prop.getProperty("appearTime", "0").trim()));
    this.setAllUserNum(Long.parseLong(prop.getProperty("allUserNum", "0").trim()));
    this.setLastRegUser(prop.getProperty("lastRegUser", ""));
    this.setPostMainNum(Long.parseLong(prop.getProperty("postMainNum", "0").trim()));
    this.setPostNum(Long.parseLong(prop.getProperty("postNum", "0").trim()));
    this.setAppearTimeStr(Util.formatDateTime(new Date(this.getAppearTime())));//寫時間用
    fis.close();
   } catch (NumberFormatException ex) {
    logger.error(ex);
   } catch (FileNotFoundException ex) {
    logger.error(ex);
   } catch (IOException ex) {
    logger.error(ex);
   }
} else {
   save(); //文件不存在時!內部private方法哦
}
}

private void save() {
String path = this.getUserConfig().getSafePath() + "sysstat.properties";
Properties prop = new Properties();
prop.setProperty("onlineNum", String.valueOf(this.getOnlineNum()));
prop.setProperty("appearTime", String.valueOf(this.getAppearTime()));
prop.setProperty("allUserNum", String.valueOf(this.getAllUserNum()));
prop.setProperty("lastRegUser", this.getLastRegUser());
prop.setProperty("postNum", String.valueOf(this.getPostNum()));
prop.setProperty("postMainNum", String.valueOf(this.getPostMainNum()));
try {
   FileOutputStream fos = new FileOutputStream(path);//寫入新文件中
   prop.store(fos, "sysstat.properties");
   fos.close();
} catch (FileNotFoundException ex) {
   logger.error(ex);
} catch (IOException ex) {
   logger.error(ex);
}
}

我們看下對抽象類的實現吧:(先load一下資源文件,再set相關的key值,最後用私有的save一下)
public void saveAllUserNum(long allusernum, String lastreguser) {
this.load();
this.setAllUserNum(allusernum);
this.setLastRegUser(lastreguser);
this.save();
}
public void saveOnline(long nowonlinenum) {
this.load();
if (nowonlinenum > this.getOnlineNum()) { //好象不太對,不然只有多沒有少!
   long atime = System.currentTimeMillis();
   this.setOnlineNum(nowonlinenum);
   this.setAppearTime(atime);
   this.setAppearTimeStr(Util.formatDateTime(new Date(atime)));
   this.save();
}
}
public void savePostNum(long main, long all) {
this.load();
this.setPostMainNum(main);
this.setPostNum(all);
this.save();
}
OK!終於可以回到BoardServiceCachImp實現類中了,繞了好大一個彎!由於還有許多東西沒用過,只能推測一下其用法了哦~~~還是先看幾個,createBoard(Board board)先:
@SuppressWarnings("unchecked")
public Board createBoard(Board board) throws BbscsException {
try {
   Board pboard = this.getBoardDAO().getBoardByID(board.getParentID()); // 取得父級版區
   if (pboard != null) { // 父級版區存在
    List pboards = new ArrayList();
    pboards.addAll(pboard.getParentIDs());//父的祖先
    pboards.add(pboard.getId());//父
/** addAll(Collection c) 
add(int index,Elelemt e) 
注意parentIDs和childIDs均爲List是由自定義userType的
public Class returnedClass() {
return List.class;
}
決定返回是List類型的!
*/
    board.setParentIDs(pboards); // 設置父級版區列表字段
    board.setLevel(pboard.getLevel() + 1); // 設置級別,在父級別上+1
   }
   board = this.getBoardDAO().saveBoard(board);//這裏的其它參數由添加時決定,不需要改變,或由其它因素相關!由DAO完成實質的工作

   if (pboard != null) {
    List pcboards = this.getBoardDAO().findBoardsByParentID(board.getParentID(), 1, -1,
      Constant.FIND_BOARDS_BY_ORDER); 
/** 取得父級半區的所有子版區列表pcboard,1是useStat,-1是hidden,FIND_BOARD_BY_ORDER=0另外有,

/*

}
return l;
}

*/
    pboard.setChildIDs(cids); // 設置父級版區的所有子版區列表字段
    this.getBoardDAO().saveBoard(pboard);//更新父信息
    this.getBoardCache().remove(pboard.getId());
/**從Board Cache中清除, 我們看下BoardCache的bean定義:

public void remove(Object key) {
logger.debug("Remove from cache [Key:" + key + "]");
this.admin.flushEntry(key.toString());
}

*/
   }

   this.clearBoradListSysListCache(board.getParentID());
/**它其實是一私有方法哦!需要注意的是實質用了SysListOjbCache,它其中的對象標識竟是[][][][][],5555,可能有些對象後三者可不用:

String[] hiddens = { "-1", "0", "1" };
String[] orderTypes = { "0", "1", "2" };
for (int i = 0; i < useStats.length; i++) {
   for (int j = 0; j < hiddens.length; j++) {
    for (int x = 0; x < orderTypes.length; x++) {
     this.getSysListObjCache().remove(
       "[B][" + pid + "][" + useStats[i] + "][" + hiddens[j] + "][" + orderTypes[x] + "]");
    }
   }
}
}
*/

   // 爲版區增加用戶組版區權限
   List gl = this.getUserGroupDAO().findUserGroupsAll(); 
/**取得用戶組列表

*/
   BoardPermission bp;

   for (int i = 0; i < gl.size(); i++) {
    UserGroup ug = (UserGroup) gl.get(i);
    bp = new BoardPermission();
    bp.setBoardID(board.getId().longValue());//冗餘字段
    bp.setGroupID(ug.getId().intValue());//冗餘字段

    switch (ug.getId().intValue()) {
    case 1:
     bp.setPermissions(Constant.BOARD_PERMISSION_GROUP_LIST_1);
/**

}
*/
   }

   return board;

} catch (Exception e) {
   logger.error(e);
   throw new BbscsException(e);
}

}
從創建中可以知道,它調用了兩個cache(sysListObjCache和boardCache,對父級和本級的相關項進行更新(或產生),再保存.還有就是對此分版區(論壇)的用戶權限的寫入.總的來說,原則上,要數據服務(保存和查找)從DAO層來,要Cache從服務層來,要常用服務也從服務層來(因爲它不參與DAO工作)

接下來,我們繼續看findBoardAllTree:
@SuppressWarnings("unchecked")//類型安全問題
public List findBoardsAllTree(long pid, List topList, int useStat, int hidden, int orderType) {
List l = this.getBoardDAO().findBoardsByParentID(pid, useStat, hidden, orderType);//這個pid指的是當前論壇,與前面的pid不一樣哦

for (int i = 0; i < l.size(); i++) {
   Board b = (Board) l.get(i);
   topList.add(b);
   this.findBoardsAllTree(b.getId().longValue(), topList, useStat, hidden, orderType);//由於topList是一個引用類型,可遞歸得到All子論壇及子論壇的子論壇...
}
return topList;
}
而這個服務類的findBoardByParentID(非DAO)它首先是查詢SysListObjCache裏面有沒有,若沒有的話再由DAO從數據庫中找,且放入到SysListObjCache中,用了add方法,需注意的是其命名有點怪哦!

public List findBoardsByParentID(long pid, int useStat, int hidden, int orderType) {
List l = (List) this.getSysListObjCache().get(
    "[B][" + pid + "][" + useStat + "][" + hidden + "][" + orderType + "]");
if (l == null) {
   // l = this.getBoardDAO().findBoardsByParentID(pid, useStat, hidden,
   // orderType);
   l = this.getBoardDAO().findBoardIdsByParentID(pid, useStat, hidden, orderType);
   this.getSysListObjCache().add("[B][" + pid + "][" + useStat + "][" + hidden + "][" + orderType + "]", l);
}
List bl = new ArrayList();
if (l != null && !l.isEmpty()) {
   for (int i = 0; i < l.size(); i++) {
    // Board b = this.getBoardByID(((Long)l.get(i)).longValue());
    Board b = this.getBoardByID((Long) l.get(i));
    if (b != null) {
     bl.add(b);
    }
   }
}
由於Cache中不一定是Borad對象了,由於add進的是list,便由List類型的bl重新加載一次爲Board的List.findBoardInIDs根據IDs一個取一個,邊放入到l中!
public List findBoardsInIDs(List ids) {
List l = new ArrayList();
if (ids != null && !ids.isEmpty()) {
   for (int i = 0; i < ids.size(); i++) {
    // Board b = this.getBoardByID(((Long) ids.get(i)).longValue());
    Board b = this.getBoardByID((Long) ids.get(i));
    if (b != null) {
     l.add(b);
    }
   }
}
return l;
}
return bl;
}
與其相反的方法是:
public List getBoardIDs(List boards) {
List l = new ArrayList();
for (int i = 0; i < boards.size(); i++) {
   Board b = (Board) boards.get(i);
   l.add(b.getId());
}
return l;
}
注意以上都有this.getBoardByID(),它是帶Cache的哦!從BoardCache中取!
public Board getBoardByID(long id) {
Board board = (Board) this.getBoardCache().get(new Long(id));
if (board == null) {
   board = this.getBoardDAO().getBoardByID(id);
   if (board != null) {
    this.getBoardCache().add(board.getId(), board);
   }
}
return board;
}
另外,對於Permission,有以下幾個方法:
public Map[] getBoardMasterPermission(int roleID) 
public Map[] getBoardPermission(long bid, int groupID)
private Map[] getPermissionMaps(long bid, int groupID) 
private Map[] getPermissionMaps(int roleID)
前面2個是公開的方法,後2個是被調用的..
public Map[] getBoardMasterPermission(int roleID) {
if (Constant.USE_PERMISSION_CACHE) {
   Map[] mapPermission = (Map[]) this.getUserPermissionCache().get("R_" + String.valueOf(roleID));
   if (mapPermission == null) {
    mapPermission = this.getPermissionMaps(roleID);
    this.getUserPermissionCache().add("R_" + String.valueOf(roleID), mapPermission);
   }
   return mapPermission;
} else {
   return this.getPermissionMaps(roleID);
}
}
private Map[] getPermissionMaps(int roleID) {
Map[] mapPermission = { new HashMap(), new HashMap() }; //MAP數組,555

Role role = this.getRoleDAO().findRoleByID(roleID);//得到id爲roleID的角色對象
List permissions = role.getPermissions(); // 取得角色的權限ID列表(ID的List)
if (permissions != null && !permissions.isEmpty()) {
   List permissionList = this.getPermissionDAO().findPermissionnIDs(permissions); // 取得權限列表Permission對象的List
   for (int i = 0; i < permissionList.size(); i++) {
    Permission permission = (Permission) permissionList.get(i);
    if (permission.getTypeID() == 2) {
     mapPermission[0].put(permission.getResource() + "," + permission.getAction(), permission);
    }
    if (permission.getTypeID() == 3) {
     mapPermission[1].put(permission.getId(), permission);
    } //這段需理解!!!
   }
}
return mapPermission;
}
另外,除了版主外,還有版區權限:
public Map[] getBoardPermission(long bid, int groupID) {
if (Constant.USE_PERMISSION_CACHE) {
   Map[] mapPermission = (Map[]) this.getUserPermissionCache().get(
     "BG_" + String.valueOf(bid) + "_" + String.valueOf(groupID));
   if (mapPermission == null) {
    mapPermission = this.getPermissionMaps(bid, groupID);
    this.getUserPermissionCache().add("BG_" + String.valueOf(bid) + "_" + String.valueOf(groupID),
      mapPermission);
   }
   return mapPermission;
} else {
   return this.getPermissionMaps(bid, groupID);
}
}
同樣,它用了類似的重載方法:
private Map[] getPermissionMaps(long bid, int groupID) {
Map[] boardPermission = { new HashMap(), new HashMap() };
BoardPermission bp = this.getBoardPermissionDAO().findBoardPermissionByBidGid(bid, groupID);//用的是BoardPermissionDAO
List permissions = bp.getPermissions(); // 取得權限ID列表
if (permissions != null && !permissions.isEmpty()) {
   List permissionList = this.getPermissionDAO().findPermissionnIDs(permissions); // 取得權限列表Permission對象的List
   for (int i = 0; i < permissionList.size(); i++) {
    Permission permission = (Permission) permissionList.get(i);
    if (permission.getTypeID() == 2) {
     boardPermission[0].put(permission.getResource() + "," + permission.getAction(), permission);
    }
    if (permission.getTypeID() == 3) {
     boardPermission[1].put(permission.getId(), permission);
    }
   }
}
return boardPermission;
}
接下來,看看getNextOrder(long pid),getPostSumNum(int mainorall,int usStat,int hidden),它們完全由DAO去查詢數據庫!我們看下remove系列:
public void removeBoard(Board board) throws BbscsException {
try {
   Long lbid = board.getId();
   long pbid = board.getParentID();
   Board pboard = this.getBoardDAO().getBoardByID(board.getParentID()); // 取得父版區

   this.getBoardDAO().removeBoard(board); // 刪除版區
   this.getBoardPermissionDAO().removeBoardPermissionsByBid(board.getId().longValue());//刪除對應版區的權限

   if (pboard != null) { // 父版區存在,對ChildIDs字段做矯正
    List pcboards = this.getBoardDAO().findBoardsByParentID(pboard.getId().longValue(), 1, 0,
      Constant.FIND_BOARDS_BY_ORDER);//pcboards是子對象
    List cids = this.getBoardIDs(pcboards);//cids是子IDs
    pboard.setChildIDs(cids);
    this.getBoardDAO().saveBoard(pboard);
   }

   this.getBoardCache().remove(lbid);
   this.clearBoradListSysListCache(pbid);
//清理本id的BoardCache,清理父id的SysListObjectCache,而userPermission中出現過去2類:R_ BG_的..都不好清理!
} catch (Exception ex) {
   logger.error(ex);
   throw new BbscsException(ex);
}
}
public void removeBoardTag(Board board, String tagID) throws BbscsException {
BoardTag bt = null;
Iterator it = board.getBoardTag().iterator(); //由Iterator遍歷查找,找到後remove掉
while (it.hasNext()) {
   bt = (BoardTag) it.next();
   if (bt.getId().equals(tagID)) {
    board.getBoardTag().remove(bt);
    break;
   }
}
try {
   board = this.getBoardDAO().saveBoard(board); //保存修改結果
   this.getForumDAO().updateForumsTag(tagID, "0", "");//帖子TAG
   this.getForumHistoryDAO().updateForumsTag(tagID, "0", "");//歷史貼TAG
   this.getBoardCache().remove(board.getId());//BoardCache清理一次
} catch (Exception e) {
   logger.error(e);
   throw new BbscsException(e);
}

}
最後再看兩個方法:
public Board updateBoard(Board board, long oldParentID) throws BbscsException {
try {
   Board pboard = this.getBoardDAO().getBoardByID(board.getParentID());

   if (pboard != null) {
    List pboards = new ArrayList();
    pboards.addAll(pboard.getParentIDs());
    pboards.add(pboard.getId());
    board.setParentIDs(pboards);
    board.setLevel(pboard.getLevel() + 1);
   } else {
    board.setParentIDs(new ArrayList());//hbm.xml決定需List對象
    board.setLevel(0);
   }
/**
數據庫中的數據id /parentID/ParentIDs/ChildIDs
1/ 0/     /2,3
2/ 1/    1/
3/ 1/    1/
*/
   board = this.getBoardDAO().saveBoard(board);

   if (pboard != null) {
    List pcboards = this.getBoardDAO().findBoardsByParentID(board.getParentID(), 1, -1,
      Constant.FIND_BOARDS_BY_ORDER);
    List cids = this.getBoardIDs(pcboards);
    pboard.setChildIDs(cids);
    this.getBoardDAO().saveBoard(pboard);
    this.getBoardCache().remove(pboard.getId());
   }
   this.clearBoradListSysListCache(board.getParentID());

   if (oldParentID != -1) { // 父級版區改變。修正父級版區數據 關鍵點,由傳入的oldParentID決定是否改變ParentID
    Board pboardOld = this.getBoardDAO().getBoardByID(oldParentID);
    if (pboardOld != null) {
     List pcboards = this.getBoardDAO().findBoardsByParentID(pboardOld.getId().longValue(), 1, -1,
       Constant.FIND_BOARDS_BY_ORDER);
     List cids = this.getBoardIDs(pcboards);
     pboardOld.setChildIDs(cids);
     this.getBoardDAO().saveBoard(pboardOld);
     this.getBoardCache().remove(pboardOld.getId());
     this.clearBoradListSysListCache(oldParentID);
    }
   }
   this.getBoardCache().remove(board.getId()); // 從Cache中清除

   return board;
} catch (Exception ex) {
   logger.error(ex);
   throw new BbscsException(ex);
}
}
最後一個方法了:
public void saveBoardsPostNumCount() throws BbscsException {
long totalNum = 0;
long totalMainNum = 0;
List bl = findBoardsByParentID(0, 1, -1, Constant.FIND_BOARDS_BY_ORDER);//從0繼承的版區有顯示主題數和貼子數的需求
for (int i = 0; i < bl.size(); i++) {
   Board b = (Board) bl.get(i);
   if (b.getBoardType() == 3) { //可發貼的版區吧!
    b.setMainPostNum(this.getForumDAO().getForumNum(b.getId(), 1, 0, 0, -1)
      + this.getForumHistoryDAO().getForumNum(b.getId(), 1, 0, 0, -1));
    b.setPostNum(this.getForumDAO().getForumNum(b.getId(), -1, 0, 0, -1)
      + this.getForumHistoryDAO().getForumNum(b.getId(), -1, 0, 0, -1));
//isNew=-1表示非主題貼,而1則相反!
    try {
     b = this.getBoardDAO().saveBoard(b);
     totalNum = totalNum + b.getPostNum();
     totalMainNum = totalMainNum + b.getMainPostNum();
     // if (Constant.USE_CLUSTER) {
     this.getBoardCache().remove(b.getId()); // 從Cache中清除
     // } else {
     // this.getBoardCache().add(b.getId(), b);
     // }
    } catch (Exception ex1) {
     logger.error(ex1);
     throw new BbscsException(ex1);
    }
   }
   List bl2 = findBoardsByParentID(b.getId(), 1, -1, Constant.FIND_BOARDS_BY_ORDER); //子論壇的更新
   if (!bl2.isEmpty()) {
    for (int j = 0; j < bl2.size(); j++) {
     Board b2 = (Board) bl2.get(j);
     if (b2.getBoardType() == 3) {
      b2.setMainPostNum(this.getForumDAO().getForumNum(b2.getId(), 1, 0, 0, -1)
        + this.getForumHistoryDAO().getForumNum(b2.getId(), 1, 0, 0, -1));
      b2.setPostNum(this.getForumDAO().getForumNum(b2.getId(), -1, 0, 0, -1)
        + this.getForumHistoryDAO().getForumNum(b2.getId(), -1, 0, 0, -1));
      try {
       b2 = this.getBoardDAO().saveBoard(b2);
       totalNum = totalNum + b2.getPostNum();
       totalMainNum = totalMainNum + b2.getMainPostNum();
       // if (Constant.USE_CLUSTER) {
       this.getBoardCache().remove(b2.getId()); // 從Cache中清除
