shiro+springmvc+mybatis【轉】

<span style="background-color: rgb(255, 255, 255); font-family: Arial, Helvetica, sans-serif;">
</span>

一直以來，從開發到現在，都還沒自己研究過權限控制。問了老大，老大讓我學習shiro。

<span style="background-color: rgb(255, 255, 255); font-family: Arial, Helvetica, sans-serif;">先講一下shiro配置吧。</span>

需要jar包：

shiro-all-1.2.4.jar

ehcache-2.7.2.jar

slf4j-log4j12-1.6.1-javadoc.jar

slf4j.api-1.6.1.jar

log4j-1.2.15.jar

都是相互依賴的包。

配置文件：spring-shiro.xml

從<bean id="monitorRealm" class="com.test.util.MonitorRealm"/>可以看出我們需要一個java類來控制驗證，

package com.test.util;
import java.util.ArrayList;
import java.util.List;
import javax.annotation.Resource;
import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.AuthenticationInfo;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.authc.SimpleAuthenticationInfo;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.authz.AuthorizationException;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.authz.SimpleAuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;
import com.test.dao.PermissionDao;
import com.test.dao.RoleDao;
import com.test.dao.UserDao;
import com.test.model.Permission;
import com.test.model.RoleBean;
import com.test.model.UserBean;
public class MonitorRealm extends AuthorizingRealm{
@Resource(name="userDao")
private UserDao userDao;
@Resource(name="roleDao")
private RoleDao roleDao;
@Resource(name="permissionDao")
private PermissionDao permissionDao;
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
String currentUsername = (String)super.getAvailablePrincipal(principals);
UserBean user = userDao.findUserByName(currentUsername);
List<String> roles = new ArrayList<String>();
List<String> permissions = new ArrayList<String>();
if(null != user){
List<RoleBean> list1 = roleDao.findLikeEntity(user.getId());
if(null != list1 && !list1.isEmpty()){
for(RoleBean role:list1){
roles.add(role.getName());
List<Permission> list = permissionDao.findEntity(role.getId());
if(null != list && !list.isEmpty()){
for(Permission permission:list){
permissions.add(permission.getUrl());
}
}
}
}
}else{
throw new AuthorizationException();
}
SimpleAuthorizationInfo simpleAuthorInfo = new SimpleAuthorizationInfo();
simpleAuthorInfo.addRoles(roles);
simpleAuthorInfo.addStringPermissions(permissions);
//實際中可能會像上面註釋的那樣從數據庫取得
if(null!=currentUsername && "admin".equals(currentUsername)){
//添加一個角色,不是配置意義上的添加,而是證明該用戶擁有admin角色
simpleAuthorInfo.addRole("admin");
//添加權限
simpleAuthorInfo.addStringPermission("admin:manage");
System.out.println("已爲用戶[mike]賦予了[admin]角色和[admin:manage]權限");
return simpleAuthorInfo;
}
//若該方法什麼都不做直接返回null的話,就會導致任何用戶訪問/admin/listUser.jsp時都會自動跳轉到unauthorizedUrl指定的地址
//詳見applicationContext.xml中的<bean id="shiroFilter">的配置
return null;
}
protected AuthenticationInfo doGetAuthenticationInfo(
AuthenticationToken authcToken) throws AuthenticationException {
UsernamePasswordToken token = (UsernamePasswordToken) authcToken;
UserBean user = new UserBean();
user.setLoginName(token.getUsername());
user.setPasswd(new String(token.getPassword()));
List<UserBean> list = userDao.login(user);
if(!list.isEmpty()){
return new SimpleAuthenticationInfo(user,
user.getPasswd().toCharArray(), getName());
}
return null;
}
}

當你在login時

@RequestMapping(value="login.do",method=RequestMethod.POST)
public String login(UserBean user,HttpSession session,Model model){
Subject currentUser = SecurityUtils.getSubject();
UsernamePasswordToken token = new UsernamePasswordToken(
user.getLoginName(), user.getPasswd());
token.setRememberMe(true);
try {
currentUser.login(token);
} catch (AuthenticationException e) {
model.addAttribute("status", 1);
return "error";
}
if(currentUser.isAuthenticated()){
session.setAttribute("userinfo", user);
return "page/index";
}else{
return "login";
}
}

currentUser.login(token); 就會調用 monitorRealm裏的doGetAuthenticationInfo方法

並將用戶名密碼傳遞過去。

數據庫查找，當用戶密碼正確時

return new SimpleAuthenticationInfo(user, user.getPasswd().toCharArray(), getName());

否則 return null

return null 就會被catch到AuthenticationException

也有一種情況，就是如果你沒有使用加密，然後你配置文件使用了加密配置了。

則會報一個Caused by: java.lang.IllegalArgumentException: Odd number of characters.的錯誤。
