MyBatis Generator 生成实体，mapper和mapper.xml文件的方法

1.首先在pom.xml引入所需要的jar包依赖

        <dependency>
    <groupId>org.mybatis.generator</groupId>
    <artifactId>mybatis-generator-core</artifactId>
    <version>1.3.5</version>
        </dependency>

2.在项目的根目录下创建一个mybatis-generator.xml如图：

mybatis-generator.xml 配置文件。

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration
  PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
  "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">


<generatorConfiguration>
 


  <context id="DB2Tables" targetRuntime="MyBatis3">
    
    <!--去除多余的注释  -->
    <commentGenerator >  
            <property name="suppressAllComments" value="true"/>  
    </commentGenerator> 
      
    <jdbcConnection 
        driverClass="com.mysql.jdbc.Driver"
        connectionURL="jdbc:mysql://127.0.0.1:3306/frame"
        userId="root"
        password="pass">
    </jdbcConnection>


    <javaTypeResolver >
      <property name="forceBigDecimals" value="false" />
    </javaTypeResolver>


    <javaModelGenerator 
        targetPackage="com.hty.pojo" 
        targetProject=".\src\main\java">
      <property name="enableSubPackages" value="false" />
      <property name="trimStrings" value="true" />
    </javaModelGenerator> 


    <sqlMapGenerator 
        targetPackage="mapper"  
        targetProject=".\src\main\resources">
      <property name="enableSubPackages" value="false" />
    </sqlMapGenerator>


    <javaClientGenerator type="XMLMAPPER" 
        targetPackage="com.hty.dao"  
        targetProject=".\src\main\java">
      <property name="enableSubPackages" value="false" />
    </javaClientGenerator>
	
    <table  tableName="userInfo" domainObjectName="UserInfor" 
         enableCountByExample="false" 
         enableUpdateByExample="false" 
         enableDeleteByExample="false"
    	 enableSelectByExample="false" 
    	 selectByExampleQueryId="false" >
    </table>


  </context>
</generatorConfiguration>

3.创建执行逆向工程的代码如下：

public class Mbg {

	public static void main(String[] args) throws Exception {
		List<String> warnings = new ArrayList<String>();
		   boolean overwrite = true;
		   File configFile = new File("mybatis-generator.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);
		   System.out.println("执行完毕");
	}

}

4.执行一下上述代码，刷新项目就可以得到相应的实体类和mapper文件以及对应的mapper.xml文件。
