mybatis-generator生成相对应的po、dao以及mapper

本文主要是介绍mybatis-generator生成相对应的po、dao以及mapper，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

1、下载mybatis-generator相应的jar包文件，可以进入http://search.maven.org/#search找到不同版本的jar包；

2、进入http://mybatis.github.io/generator/configreference/xmlconfig.html官方网站查看官方文档，选择你相应的方式来生成po、dao、mapper文件，本来选择的是配置文件+java文件来生成一系列文件。下面给出相对应的文件代码：

mybatis-genertor.xml:

<?xml version="1.0" encoding="UTF-8"?>

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

                <property name="trimStrings" value="true" />
            </javaModelGenerator>
            
            <sqlMapGenerator targetPackage="com.sk.main.entity.mapper"

            </sqlMapGenerator>
            
            <javaClientGenerator type="XMLMAPPER"
                targetPackage="com.sk.main.dao"

                <property name="enableSubPackages" value="false" />
            </javaClientGenerator>
            
            <table tableName="t_sys_user" domainObjectName="User" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>

   public void generator() throws IOException, XMLParserException, InvalidConfigurationException, SQLException, InterruptedException{
       List<String> warnings = new ArrayList<String>();
           boolean overwrite = true;
           System.out.println(this.getClass().getResource("/").getPath());
           File configFile = new File(this.getClass().getResource("/").getPath()+"mybatis-generator.xml");//获取配置文件
           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);
   }

}

以上代码是测试可用。
