Mybatis简单使用——Generator（6）

文档地址：http://www.mybatis.org/generator/configreference/xmlconfig.html

（1）添加包：
<dependency>
    <groupId>org.mybatis.generator</groupId>
    <artifactId>mybatis-generator-core</artifactId>
    <version>1.3.5</version>
</dependency>

（2）添加插件

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
        <!-- mybatis generator 自动生成代码插件 -->
        <plugin>
            <groupId>org.mybatis.generator</groupId>
            <artifactId>mybatis-generator-maven-plugin</artifactId>
            <version>1.3.2</version>
            <configuration>
                <configurationFile>${basedir}/src/main/resources/generator/generatorConfig.xml</configurationFile>
                <overwrite>true</overwrite>
                <verbose>true</verbose>
            </configuration>
        </plugin>
    </plugins>
</build>

（3）generator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>
  <!--根据自己包所在位置修改-->
    <classPathEntry  location="C:\Users\Administrator\.m2\repository\mysql\mysql-connector-java\5.1.44\mysql-connector-java-5.1.44.jar"/>
   <!-- 
      targetRuntime="MyBatis3Simple":生成简单版的CRUD
      MyBatis3:豪华版
   
    -->
  <context id="DB2Tables" targetRuntime="MyBatis3">
   <!-- jdbcConnection：指定如何连接到目标数据库 -->
    <jdbcConnection driverClass="com.mysql.jdbc.Driver"
        connectionURL="jdbc:mysql://localhost:3306/mapper?allowMultiQueries=true"
        userId="root"
        password="[email protected]">
    </jdbcConnection>

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

   <!-- javaModelGenerator：指定javaBean的生成策略 
   targetPackage="test.model"：目标包名
   targetProject="\MBGTestProject\src"：目标工程
   -->
    <javaModelGenerator targetPackage="com.nnT.mybatis.bean"
          targetProject="src/main/java">
      <property name="enableSubPackages" value="true" />
      <property name="trimStrings" value="true" />
    </javaModelGenerator>

   <!-- sqlMapGenerator：sql映射生成策略： -->
    <sqlMapGenerator targetPackage="mappers"
       targetProject="src/main/resources">
      <property name="enableSubPackages" value="true" />
    </sqlMapGenerator>

   <!-- javaClientGenerator:指定mapper接口所在的位置 -->
    <javaClientGenerator type="XMLMAPPER" targetPackage="com.nnT.mybatis.dao"
       targetProject="src/main/java">
      <property name="enableSubPackages" value="true" />
    </javaClientGenerator>

   <!-- 指定要逆向分析哪些表：根据表要创建javaBean -->
    <table tableName="country" domainObjectName="Country" ></table>
  </context>
</generatorConfiguration>

或：

@Test
public void testMbg() throws Exception {
    List<String> 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((ProgressCallback)null);
}
