反向生成实体类
仅作为学习笔记，所以本文可能说的不是那么明了，就像我最初目的并不是为了讲懂读者一样。谅解！
目录结构
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">
<!--利用mybatis generator反向生成数据库对应的model实体-->
<generatorConfiguration>
<!-- mysql-connector文件路径 -->
<classPathEntry location="mysql-connector-java-8.0.17.jar"/>
<context id="DB2Tables" targetRuntime="MyBatis3">
<commentGenerator>
<property name="suppressDate" value="true"/>
<property name="suppressAllComments" value="true"/>
</commentGenerator>
<!-- 链接配置 输入数据库名及密码 -->
<jdbcConnection driverClass="com.mysql.cj.jdbc.Driver" userId="root" password="0000"
connectionURL="jdbc:mysql://127.0.0.1:3306/dbName"/>
<javaTypeResolver>
<property name="forceBigDecimals" value="false"/>
</javaTypeResolver>
<!-- 生成实体类的路径，这个路径可以自动生成，但是必须有src这个路径-->
<!-- 比如 E:\path\to\your\project\src -->
<javaModelGenerator targetPackage="blog.entity" targetProject="src">
<property name="enableSubPackages" value="true"/>
<property name="trimStrings" value="true"/>
</javaModelGenerator>
<!-- 生成映射的路径，blog.mapXML这个路径可以自动生成，但是必须有src这个路径-->
<sqlMapGenerator targetPackage="blog.mapXML" targetProject="src">
<property name="enableSubPackages" value="true"/>
</sqlMapGenerator>
<!-- 生成接口的路径，这个路径可以自动生成，但是必须有src这个路径-->
<javaClientGenerator type="XMLMAPPER" targetPackage="blog.dao" targetProject="src">
<property name="enableSubPackages" value="true"/>
</javaClientGenerator>
<!-- 不要改变标签顺序
The content of element type "context" must match
"(property*,plugin*,commentGenerator?,jdbcConnection,javaTypeResolver?,javaModelGenerator,sqlMapGenerator?,javaClientGenerator?,table+)".
原因：配置文件 generatorConfig.xml 里面的context的子元素必须按照它给出的顺序，如错误提示的match“……”部分。

</generatorConfiguration>执行命令
java -jar mybatis-generator-core-1.3.7.jar -configfile generatorConfig.xml -overwrite打开终端
执行结束

ftl模板
注意后面的属性要与实体类里面的属性变量名保持一样
${user}
${user.userId}
${user.userEmail}
${user.userPswd}
${user.userPhone}
${user.userNickName}
${user.userState}
${user.userGraphUrl}
${user.userAvailable}测试类
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({"classpath:spring-mybatis.xml"})
public class FreeM {
@Autowired
private UserMainMapper userMainMapper;
@Test
public void testFindUserById() {
Map<String, Object> model = new HashMap<String, Object>();
Long id = 1L;
UserMain userMain = this.userMainMapper.selectByPrimaryKey(id);
model.put("user", userMain);
Configuration cof = new Configuration();
cof.setObjectWrapper(new DefaultObjectWrapper());
try {
cof.setTemplateLoader(new FileTemplateLoader(new File("E:/Desktop/blog")));
//绝对路径：E:/Desktop/blog/src/main/resources/freeMarker/temp.ftl
Template temp = cof.getTemplate("/src/main/resources/freeMarker/temp.ftl");
StringWriter writer = new StringWriter();
temp.process(model, writer);
System.out.println(writer.toString());
} catch (IOException e) {
e.printStackTrace();
} catch (TemplateException e) {
e.printStackTrace();
}
System.err.println(userMain.toString());
}
}运行结果
UserMain{Id=1, Email='123456@qq.com', Pswd='0000', Phone='123456', NickName='乔峰', State='1', GraphUrl='null', Available='1'}
