java代码生成器怎么用

zip包，然后自动下载下来

1.预先定义好模板

2.界面输入相关参数

3.解析模板生成代码并下载

最后放出源代码：

package com.et.controller.system.createcode;

import java.util.ArrayList;

import java.util.Date;

import java.util.HashMap;

import java.util.List;

import java.util.Map;

import javax.servlet.http.HttpServletResponse;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;

import com.et.controller.base.BaseController;

import com.et.util.DelAllFile;

import com.et.util.FileDownload;

import com.et.util.FileZip;

import com.et.util.Freemarker;

import com.et.util.PageData;

import com.et.util.PathUtil;

/**

/**

@RequestMapping(value=”/proCode”)

public void proCode(HttpServletResponse response) throws Exception{

PageData pd = new PageData();

pd = this.getPageData();

/* ============================================================================================= */

String packageName = pd.getString(“packageName”); //包名 ========1

String objectName = pd.getString(“objectName”); //类名 ========2

String tabletop = pd.getString(“tabletop”); //表前缀 ========3

tabletop = null == tabletop?””:tabletop.toUpperCase(); //表前缀转大写

String zindext = pd.getString(“zindex”); //属性总数

int zindex = 0;

if(null != zindext !””.equals(zindext)){

zindex = Integer.parseInt(zindext);

}

ListString[] fieldList = new ArrayListString[](); //属性集合 ========4

for(int i=0; i zindex; i++){

fieldList.add(pd.getString(“field”+i).split(“,fh,”)); //属性放到集合里面

}

MapString,Object root = new HashMapString,Object(); //创建数据模型

root.put(“fieldList”, fieldList);

root.put(“packageName”, packageName); //包名

root.put(“objectName”, objectName); //类名

root.put(“objectNameLower”, objectName.toLowerCase()); //类名(全小写)

root.put(“objectNameUpper”, objectName.toUpperCase()); //类名(全大写)

root.put(“tabletop”, tabletop); //表前缀

root.put(“nowDate”, new Date()); //当前日期

DelAllFile.delFolder(PathUtil.getClasspath()+”admin/ftl”); //生成代码前,先清空之前生成的代码

/* ============================================================================================= */

String filePath = “admin/ftl/code/”; //存放路径

String ftlPath = “createCode”; //ftl路径

/*生成controller*/

Freemarker.printFile(“controllerTemplate.ftl”, root, “controller/”+packageName+”/”+objectName.toLowerCase()+”/”+objectName+”Controller.java”, filePath, ftlPath);

/*生成service*/

Freemarker.printFile(“serviceTemplate.ftl”, root, “service/”+packageName+”/”+objectName.toLowerCase()+”/”+objectName+”Service.java”, filePath, ftlPath);

/*生成mybatis xml*/

Freemarker.printFile(“mapperMysqlTemplate.ftl”, root, “mybatis_mysql/”+packageName+”/”+objectName+”Mapper.xml”, filePath, ftlPath);

Freemarker.printFile(“mapperOracleTemplate.ftl”, root, “mybatis_oracle/”+packageName+”/”+objectName+”Mapper.xml”, filePath, ftlPath);

/*生成SQL脚本*/

Freemarker.printFile(“mysql_SQL_Template.ftl”, root, “mysql数据库脚本/”+tabletop+objectName.toUpperCase()+”.sql”, filePath, ftlPath);

Freemarker.printFile(“oracle_SQL_Template.ftl”, root, “oracle数据库脚本/”+tabletop+objectName.toUpperCase()+”.sql”, filePath, ftlPath);

/*生成jsp页面*/

Freemarker.printFile(“jsp_list_Template.ftl”, root, “jsp/”+packageName+”/”+objectName.toLowerCase()+”/”+objectName.toLowerCase()+”_list.jsp”, filePath, ftlPath);

Freemarker.printFile(“jsp_edit_Template.ftl”, root, “jsp/”+packageName+”/”+objectName.toLowerCase()+”/”+objectName.toLowerCase()+”_edit.jsp”, filePath, ftlPath);

/*生成说明文档*/

Freemarker.printFile(“docTemplate.ftl”, root, “说明.doc”, filePath, ftlPath);

//this.print(“oracle_SQL_Template.ftl”, root); 控制台打印

/*生成的全部代码压缩成zip文件*/

FileZip.zip(PathUtil.getClasspath()+”admin/ftl/code”, PathUtil.getClasspath()+”admin/ftl/code.zip”);

/*下载代码*/

FileDownload.fileDownload(response, PathUtil.getClasspath()+”admin/ftl/code.zip”, “code.zip”);
