注:基于SpringBoot下
第一步:pom文件
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.thinkbar.Hello</groupId> <artifactId>Hello</artifactId> <version>1.0-SNAPSHOT</version> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.0.0.RELEASE</version> </parent> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> <plugin> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-maven-plugin</artifactId> <version>1.3.2</version> </plugin> </plugins> </build> </project>
第二步:generatorConfig.xml
1 <?xml version="1.0" encoding="UTF-8"?> 2 <!DOCTYPE generatorConfiguration 3 PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN" 4 "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd"> 5 6 <generatorConfiguration> 7 <!--数据库驱动mysql jar 这个地方要注意确保jar的位置正确,要区分在IDEA中jar在.m2中还是自定义的文件夹中--> 8 <classPathEntry 9 location="D:\repository\mysql\mysql-connector-java\5.1.45\mysql-connector-java-5.1.45.jar"/> 10 <!--数据库驱动oracle jar --> 11 <!-- 12 <classPathEntry 13 location="E:\app\Acer\product\11.2.0\client_2\jdbc\lib\ojdbc5.jar"/>--> 14 <context id="Tables" targetRuntime="MyBatis3"> 15 <!--去除注释 --> 16 17 <commentGenerator> 18 <property name="suppressAllComments" value="true"/> 19 </commentGenerator> 20 21 <!--mysql数据库连接 --> 22 23 <jdbcConnection driverClass="com.mysql.jdbc.Driver" 24 connectionURL="jdbc:mysql://localhost:3306/user" 25 userId="root" 26 password="root"> 27 </jdbcConnection> 28 <!--oracle数据库连接 --> 29 <!-- 30 <jdbcConnection driverClass="oracle.jdbc.driver.OracleDriver" 31 connectionURL="jdbc:oracle:thin:@172.16.36.23:1521/FOKF" 32 userId="YCGCE" password="YCGCE"> 33 <property name="remarksReporting" value="true"></property> 34 </jdbcConnection>--> 35 36 <!--默认false Java type resolver will always use java.math.BigDecimal if 37 the database column is of type DECIMAL or NUMERIC. --> 38 <javaTypeResolver> 39 <property name="forceBigDecimals" value="false"/> 40 </javaTypeResolver> 41 42 <!--生成实体类 指定包名 以及生成的地址 (可以自定义地址,但是路径不存在不会自动创建 使用Maven生成在target目录下,会自动创建) --> 43 <javaModelGenerator targetPackage="com.thinkbar" 44 targetProject="E:\development_tools\javaProject\Hello\src\main\java"> 45 <property name="enableSubPackages" value="true"/> 46 <property name="trimStrings" value="true"/> 47 </javaModelGenerator> 48 <!--生成SQLMAP文件 --> 49 <sqlMapGenerator targetPackage="mapper" 50 targetProject="E:\development_tools\javaProject\Hello\src\main\resources"> 51 <property name="enableSubPackages" value="false"/> 52 </sqlMapGenerator> 53 <!--生成Dao文件 可以配置 type="XMLMAPPER"生成xml的dao实现 context id="DB2Tables" 修改targetRuntime="MyBatis3" --> 54 <javaClientGenerator type="XMLMAPPER" 55 targetPackage="com.dao" 56 targetProject="E:\development_tools\javaProject\Hello\src\main\java"> 57 <property name="enableSubPackages" value="false"/> 58 </javaClientGenerator> 59 60 <!--对应数据库表 mysql可以加入主键自增 字段命名 忽略某字段等 --> 61 <table tableName="user" domainObjectName="User" 62 enableCountByExample="false" enableUpdateByExample="false" 63 enableDeleteByExample="false" enableSelectByExample="false" 64 selectByExampleQueryId="false"/> 65 66 67 </context> 68 </generatorConfiguration>
第三步:右侧插件中找到 generatorConfig双击运行即可,注意的时当报不存在时,该插件不会自动创建
