mybatis generator逆向工程自动生成实体类，dao接口和对应的Mapper.xml文件

去mybatis generator官方文档找http://www.mybatis.org/generator/configreference/xmlconfig.html#

(1)先在pom.xml中添加依赖包

    org.mybatis.generator
    mybatis-generator-core
    1.3.5

（2）创建mbg.xml

  PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
  "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">

     
   
   
 

 
  
         driverClass="com.mysql.jdbc.Driver"
        connectionURL="jdbc:mysql://localhost:3306/course_evaluation"
        userId="root"
        password="123456">
   

            targetProject=".\src\main\java">
     
     
   

             targetProject=".\src\main\resources">
     
   

            targetPackage="com.ssm.dao"  
        targetProject=".\src\main\java">
     
   

   

 
 
 
 
 

（3）执行自动生成器

package com.maven.crud.test;

import java.io.File;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;

import org.mybatis.generator.api.MyBatisGenerator;
import org.mybatis.generator.config.Configuration;
import org.mybatis.generator.config.xml.ConfigurationParser;
import org.mybatis.generator.exception.XMLParserException;
import org.mybatis.generator.internal.DefaultShellCallback;

public class MBGTest {

    public static void main(String[] args) throws Exception {
         List warnings = new ArrayList();
           boolean overwrite = true;
           File configFile = new File("mbg.xml");
           ConfigurationParser cp = new ConfigurationParser(warnings);
           Configuration config = cp.parseConfiguration(configFile);
           DefaultShellCallback callback = new DefaultShellCallback(overwrite);
           MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config, callback, warnings);
           myBatisGenerator.generate(null);
    }

}
