webwork+hibernate+spring项目源代码自动生成(附源代码)

阅读更多

自己写了一个自动生成源代码的工具,代码自动生成,以及一个完整项目的成功实践,还在继续完善当中,采用freemaker配置模板,可以根据自己的需要生成自己想要的代码

 

先来看看怎么使用,很简单

先配置config.xml 配置设置模板路径,以及项目生成路径,可以自己定义

 

<?xml version="1.0" encoding="UTF-8"?>
<xml-body>
 <code>
  <projectpath>D:/vobuilder/vobuilder</projectpath>
  
  <model>com.hyj.model</model>
  <action>com.hyj.action</action>
  <dao>com.hyj.dao</dao>
  <daoimpl>com.hyj.dao.jdbc</daoimpl>
  <service>com.hyj.service</service>
  <serviceimpl>com.hyj.service.impl</serviceimpl> 
  <jsp>/freemarker/jsp</jsp>
   
 </code>
</xml-body>

 

 

 

CodeGenerator cg = new CodeGenerator();
cg.generate("tableName");

//这样就生成了所有项目的文件

  

 

 1.生成代码的引擎

 

package com.hyj.util;

import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.OutputStreamWriter;
import java.io.Writer;
import java.sql.Connection;
import java.util.Map;

import org.apache.log4j.LogManager;
import org.apache.log4j.Logger;

import com.szxhdz.util.Factory;

import freemarker.template.Configuration;
import freemarker.template.DefaultObjectWrapper;
import freemarker.template.Template;
import freemarker.template.TemplateException;

public abstract class AbstractEngine {

 protected static Logger logger = LogManager.getLogger(AbstractEngine.class);

 protected static Connection con;

 protected static Configuration cfg;

 public AbstractEngine(String templatePath) {
  con = Factory.getConnection();
  try {
   cfg = new Configuration();
   cfg.setDefaultEncoding("gb2312");
   cfg.setDirectoryForTemplateLoading(new File(templatePath));
   cfg.setObjectWrapper(new DefaultObjectWrapper());
  } catch (Exception e) {
   e.printStackTrace();
  }
 }

 public static void create(String ftlTemplate, Map contents, String savePath,
   String saveFilename) {
  try {
   Template temp = cfg.getTemplate(ftlTemplate);
   logger.info("generate file " + saveFilename + "  in path "
     + savePath);
   File file = new File(savePath);
   if (!file.exists()) {
    file.mkdirs();
   }
   Writer out = new OutputStreamWriter(new FileOutputStream(savePath
     + "/" + saveFilename), "gb2312");
   temp.process(contents, out);
   out.flush();
  } catch (IOException e) {
   e.printStackTrace();
  } catch (TemplateException e1) {
   e1.printStackTrace();
  }
 }
}
