一、Mybatis generator配置文件（generatorConfig.xml）
<?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>
<!-- targetRuntime="MyBatis3Simple":生成简单版的CRUD MyBatis3:豪华版 -->
<context id="mybatis" 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/mybatis?allowMultiQueries=true"
userId="root" password="123456">
</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.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="com.mybatis.dao"
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.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="tbl_dept" domainObjectName="Department"
enableCountByExample="false" enableDeleteByExample="false"
enableSelectByExample="false" enableUpdateByExample="false"></table>
<table tableName="tbl_employee" domainObjectName="Employee"
enableCountByExample="false" enableDeleteByExample="false"
enableSelectByExample="false" enableUpdateByExample="false"></table>
</context>
</generatorConfiguration>
二 、非maven环境下
1 添加jar包支持
mysql-connector-java-xxxx-bin.jar,mybatis-generator-core-xxx.jar
2 生成mybatis支持代码
@Test
public void testMbg() throws Exception {
List<String> warnings = new ArrayList<String>();
boolean overwrite = true;
File configFile = new File("generatorConfig.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);
}三、maven环境下
1 添加maven环境需要插件支持
<plugin>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-maven-plugin</artifactId>
<version>1.3.7</version>
<dependencies>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.41</version>
</dependency>
</dependencies>
</plugin>2 配置maven运行指令，并执行
先配置mybatis generator build，然后执行。
