JEESITE快速開發平臺（七）代碼生成原理

一、原理講解

jeesite代碼生成用的是FreeMarker模板引擎結合xml技術來實現的，定義的模板都放在resources/templates/modules/gen下

一看就知道crud就是基本的增刪改查，dao是數據庫操作，treetable是有關樹方面的模板，其中主要的配置文件就是config.xml,該文件中定義了生成的模板，以及java類型,查詢類型,字段顯示類型等一些數據。

<?xml version="1.0" encoding="utf-8"?>
<config>
<category>
<category value="curd" label="增刪改查（單表）">
<template>curd/controller.xml</template>
<template>curd/service.xml</template>
<template>category-ref:dao</template>
<template>curd/viewForm.xml</template>
<template>curd/viewList.xml</template>
</category>
<category value="curd_many" label="增刪改查（一對多）">

<dict value="areaselect" label="區域選擇"/>
<dict value="treeselect" label="樹選擇控件"/>
<dict value="fileselect" label="文件上傳選擇"/>
</showType>
</config>

其中

<childTable>
<template>category-ref:dao</template>
</childTable>

定義了子表，初看jeesite的代碼生成，有個困惑的地方就是,一般通過FreeMarker進行代碼生成定義的模板都是ftl格式的，而這裏卻是xml，什麼鬼，難道這裏不是用FreeMarker進行生成的??我們先來看下xml文件中的內容就清楚了:

[html] view plain copy

<?xml version="1.0" encoding="utf-8"?>
<template>
<name>controller</name>
<filePath>src/main/java/${packageName}/${moduleName}/web/${subModuleName}</filePath>
<fileName>${ClassName}Controller.java</fileName>
<content><![CDATA[
/**

*/
package ${packageName}.${moduleName}.web<#if subModuleName != "">.${subModuleName}</#if>;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.shiro.authz.annotation.RequiresPermissions;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.servlet.mvc.support.RedirectAttributes;
import com.thinkgem.jeesite.common.config.Global;
import com.thinkgem.jeesite.common.persistence.Page;
import com.thinkgem.jeesite.common.web.BaseController;
import com.thinkgem.jeesite.common.utils.StringUtils;
import ${packageName}.${moduleName}.entity<#if subModuleName != "">.${subModuleName}</#if>.${ClassName};
import ${packageName}.${moduleName}.service<#if subModuleName != "">.${subModuleName}</#if>.${ClassName}Service;
/**

* @author ${functionAuthor}
* @version ${functionVersion}
*/
@Controller
@RequestMapping(value = "${r"${adminPath}"}/${urlPrefix}")
public class ${ClassName}Controller extends BaseController {
@Autowired
private ${ClassName}Service ${className}Service;
@ModelAttribute
public ${ClassName} get(@RequestParam(required=false) String id) {
${ClassName} entity = null;
if (StringUtils.isNotBlank(id)){
entity = ${className}Service.get(id);
}
if (entity == null){
entity = new ${ClassName}();
}
return entity;
}
@RequiresPermissions("${permissionPrefix}:view")
@RequestMapping(value = {"list", ""})
public String list(${ClassName} ${className}, HttpServletRequest request, HttpServletResponse response, Model model) {
Page<${ClassName}> page = ${className}Service.findPage(new Page<${ClassName}>(request, response), ${className});
model.addAttribute("page", page);
return "${lastPackageName}/${viewPrefix}List";
}
@RequiresPermissions("${permissionPrefix}:view")
@RequestMapping(value = "form")
public String form(${ClassName} ${className}, Model model) {
model.addAttribute("${className}", ${className});
return "${lastPackageName}/${viewPrefix}Form";
}
@RequiresPermissions("${permissionPrefix}:edit")
@RequestMapping(value = "save")
public String save(${ClassName} ${className}, Model model, RedirectAttributes redirectAttributes) {
if (!beanValidator(model, ${className})){
return form(${className}, model);
}
${className}Service.save(${className});
addMessage(redirectAttributes, "保存${functionNameSimple}成功");
return "redirect:"+Global.getAdminPath()+"/${viewPrefix}/?repage";
}
@RequiresPermissions("${permissionPrefix}:edit")
@RequestMapping(value = "delete")
public String delete(${ClassName} ${className}, RedirectAttributes redirectAttributes) {
${className}Service.delete(${className});
addMessage(redirectAttributes, "刪除${functionNameSimple}成功");
return "redirect:"+Global.getAdminPath()+"/${viewPrefix}/?repage";
}
}]]>
</content>
</template>

其中的xml格式爲:

[html] view plain copy

<?xml version="1.0" encoding="utf-8"?>
<template>
<name>controller</name>
<filePath>src/main/java/${packageName}/${moduleName}/web/${subModuleName}</filePath>
<fileName>${ClassName}Controller.java</fileName>
<content><![CDATA[]]>
</content>
</template>

發現其中的奧祕沒，他把模板內容都放在了content標籤的CDATA[]區。而且config.xml有相對應的bean，用來實現xml轉對象:

[html] view plain copy

/**
* 生成方案Entity
* @author ThinkGem
* @version 2013-10-15
*/
@XmlRootElement(name="config")
public class GenConfig implements Serializable {
private static final long serialVersionUID = 1L;
private List<GenCategory> categoryList; // 代碼模板分類
private List<Dict> javaTypeList; // Java類型
private List<Dict> queryTypeList; // 查詢類型
private List<Dict> showTypeList; // 顯示類型
public GenConfig() {
super();
}
@XmlElementWrapper(name = "category")
@XmlElement(name = "category")
public List<GenCategory> getCategoryList() {
return categoryList;
}
public void setCategoryList(List<GenCategory> categoryList) {
this.categoryList = categoryList;
}
@XmlElementWrapper(name = "javaType")
@XmlElement(name = "dict")
public List<Dict> getJavaTypeList() {
return javaTypeList;
}
public void setJavaTypeList(List<Dict> javaTypeList) {
this.javaTypeList = javaTypeList;
}
@XmlElementWrapper(name = "queryType")
@XmlElement(name = "dict")
public List<Dict> getQueryTypeList() {
return queryTypeList;
}
public void setQueryTypeList(List<Dict> queryTypeList) {
this.queryTypeList = queryTypeList;
}
@XmlElementWrapper(name = "showType")
@XmlElement(name = "dict")
public List<Dict> getShowTypeList() {
return showTypeList;
}
public void setShowTypeList(List<Dict> showTypeList) {
this.showTypeList = showTypeList;
}
}

其中的

[html] view plain copy

private List<GenCategory> categoryList; // 代碼模板分類
private List<Dict> javaTypeList; // Java類型
private List<Dict> queryTypeList; // 查詢類型
private List<Dict> showTypeList; // 顯示類型

對應的就是xml中預先定義好的

[html] view plain copy

<?xml version="1.0" encoding="utf-8"?>
<config>
<category>
<category value="curd" label="增刪改查（單表）">
<template>curd/controller.xml</template>
....
</category>
<category value="curd_many" label="增刪改查（一對多）">
<template>curd/controller.xml</template>
....
<childTable>
<template>category-ref:dao</template>
</childTable>
</category>
<category value="dao" label="僅持久層（dao/entity/mapper）">
<template>dao/dao.xml</template>
....
</category>
<category value="treeTable" label="樹結構表（一體）">
<template>treetable/controller.xml</template>
....
</category>
<category value="treeTableAndList" label="樹結構表（左樹右表）">
<template>category-ref:dao</template>
</category>
</category>
<javaType>
<dict value="String" label="String"/>
....
</javaType>
<queryType>
<dict value="=" label="="/>
....
</queryType>
<showType>
<dict value="input" label="單行文本"/>
<dict value="textarea" label="多行文本"/>
....
</showType>
</config>

其中的代碼模板分類

通過@XmlElement(name = "category")引用了GenCategory類，其中定義了主子模板

[html] view plain copy

/**
* 生成方案Entity
* @author ThinkGem
* @version 2013-10-15
*/
@XmlRootElement(name="category")
public class GenCategory extends Dict {
private static final long serialVersionUID = 1L;
private List<String> template; // 主表模板
private List<String> childTableTemplate;// 子表模板
public static String CATEGORY_REF = "category-ref:";
public GenCategory() {
super();
}
@XmlElement(name = "template")
public List<String> getTemplate() {
return template;
}
public void setTemplate(List<String> template) {
this.template = template;
}
@XmlElementWrapper(name = "childTable")
@XmlElement(name = "template")
public List<String> getChildTableTemplate() {
return childTableTemplate;
}
public void setChildTableTemplate(List<String> childTableTemplate) {
this.childTableTemplate = childTableTemplate;
}
}

這兩個主子其實對應的就是

在GenUtils中通過getConfig()方法可獲取轉換成bean的對象

而其中的數據就是在配置業務表是初始化的一些數據,比如當我們選擇某一張表時，然後點擊下一步

就會調用GenTableController中的form方法，把一些配置參數設置進去

然後在genTableForm.jsp頁面進行渲染

[html] view plain copy

<%@ page contentType="text/html;charset=UTF-8" %>
<%@ include file="/WEB-INF/views/include/taglib.jsp"%>
<html>
<head>

$(this).attr("name", "_"+$(this).attr("name"));
});
form.submit();
},
errorContainer: "#messageBox",
errorPlacement: function(error, element) {
$("#messageBox").text("輸入有誤，請先更正。");
if (element.is(":checkbox")||element.is(":radio")||element.parent().is(".input-append")){
error.appendTo(element.parent().parent());

error.insertAfter(element);

注意其中的name屬性

[html] view plain copy

name="columnList[${vs.index}].xxx"

在GenTable中是用list來裝的

所以在spring mvc數據綁定的時候可以通過下標的形式來傳值

業務表配置好之後，就是生成代碼，新建生成方案配置，然後輸入一些必須的信息

點擊保存並生成代碼，會調用GenSchemeController中的save()方法，傳入一些參數

然後調用genSchemeService.save()方法進行生成

如果是1的話就生成代碼

generateCode方法如下:

[html] view plain copy

private String generateCode(GenScheme genScheme){
StringBuilder result = new StringBuilder();
// 查詢主表及字段列
GenTable genTable = genTableDao.get(genScheme.getGenTable().getId());
genTable.setColumnList(genTableColumnDao.findList(new GenTableColumn(new GenTable(genTable.getId()))));
// 獲取所有代碼模板
GenConfig config = GenUtils.getConfig();
// 獲取模板列表
List<GenTemplate> templateList = GenUtils.getTemplateList(config, genScheme.getCategory(), false); //獲取所有不包含childTableTemplateList的數據
List<GenTemplate> childTableTemplateList = GenUtils.getTemplateList(config, genScheme.getCategory(), true);
// 如果有子表模板，則需要獲取子表列表
if (childTableTemplateList.size() > 0){
GenTable parentTable = new GenTable();
parentTable.setParentTable(genTable.getName());
genTable.setChildList(genTableDao.findList(parentTable));
}
// 生成子表模板代碼
for (GenTable childTable : genTable.getChildList()){
childTable.setParent(genTable);
childTable.setColumnList(genTableColumnDao.findList(new GenTableColumn(new GenTable(childTable.getId()))));
genScheme.setGenTable(childTable);
Map<String, Object> childTableModel = GenUtils.getDataModel(genScheme);
for (GenTemplate tpl : childTableTemplateList){
result.append(GenUtils.generateToFile(tpl, childTableModel, genScheme.getReplaceFile()));
}
}
// 生成主表模板代碼
genScheme.setGenTable(genTable);
Map<String, Object> model = GenUtils.getDataModel(genScheme);
for (GenTemplate tpl : templateList){
result.append(GenUtils.generateToFile(tpl, model, genScheme.getReplaceFile()));
}
return result.toString();
}

該方法主要是做一些，獲取模板，然後進行數據綁定等一些工作。其中的

[html] view plain copy

// 獲取模板列表
List<GenTemplate> templateList = GenUtils.getTemplateList(config, genScheme.getCategory(), false); //獲取所有不包含childTableTemplateList的數據
List<GenTemplate> childTableTemplateList = GenUtils.getTemplateList(config, genScheme.getCategory(), true);

getTemplateList方法爲

[html] view plain copy

/**
* 根據分類獲取模板列表
* @param config
* @param category
* @param isChildTable 是否是子表
* @return
*/
public static List<GenTemplate> getTemplateList(GenConfig config, String category, boolean isChildTable){
List<GenTemplate> templateList = Lists.newArrayList();
if (config !=null && config.getCategoryList() != null && category != null){
for (GenCategory e : config.getCategoryList()){
if (category.equals(e.getValue())){
List<String> list = null;
if (!isChildTable){
list = e.getTemplate();
}else{
list = e.getChildTableTemplate();
}
if (list != null){
for (String s : list){
if (StringUtils.startsWith(s, GenCategory.CATEGORY_REF)){
templateList.addAll(getTemplateList(config, StringUtils.replace(s, GenCategory.CATEGORY_REF, ""), false));
}else{
GenTemplate template = fileToObject(s, GenTemplate.class);
if (template != null){
templateList.add(template);
}
}
}
}
break;
}
}
}
return templateList;
}

通過標誌位來獲取

[html] view plain copy

if (!isChildTable){
list = e.getTemplate();
}else{
list = e.getChildTableTemplate();
}

主表，子表模板，生成文件的方法是GenUtils.generateToFile(tpl, model, genScheme.getReplaceFile())

[html] view plain copy

/**
* 生成到文件
* @param tpl
* @param model
* @param isReplaceFile
* @return
*/
public static String generateToFile(GenTemplate tpl, Map<String, Object> model, boolean isReplaceFile){
// 獲取生成文件
String fileName = Global.getProjectPath() + File.separator
+ StringUtils.replaceEach(FreeMarkers.renderString(tpl.getFilePath() + "/", model),
new String[]{"//", "/", "."}, new String[]{File.separator, File.separator, File.separator})
+ FreeMarkers.renderString(tpl.getFileName(), model);
logger.debug(" fileName === " + fileName);
// 獲取生成文件內容
String content = FreeMarkers.renderString(StringUtils.trimToEmpty(tpl.getContent()), model);
logger.debug(" content === \r\n" + content);
// 如果選擇替換文件，則刪除原文件
if (isReplaceFile){
FileUtils.deleteFile(fileName);
}
// 創建並寫入文件
if (FileUtils.createFile(fileName)){
FileUtils.writeToFile(fileName, content, true);
logger.debug(" file create === " + fileName);
return "生成成功："+fileName+"<br/>";
}else{
logger.debug(" file extents === " + fileName);
return "文件已存在："+fileName+"<br/>";
}
}
