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 com.et.util.FileDownload

import com.et.util.FileZip

import com.et.util.Freemarker

import com.et.util.PageData

/*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*/

/*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”)

}

}

具体操作如下：工具里快捷键alt+shift+s

就弹出来Generate
