用Maven生成MaBatis的Mapper配置文件和接口
1.在pom.xml文件中加入依赖和插件
<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.zouwj.study</groupId> <artifactId>schoolmall</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>war</packaging> <dependencies> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.2.2</version> </dependency> <dependency> <groupId>com.oracle</groupId> <artifactId>ojdbc6</artifactId> <version>11.2.0.4.0</version> </dependency> <dependency> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-maven-plugin</artifactId> <version>1.3.2</version> </dependency> </dependencies> <build> <pluginManagement> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>1.7</source> <target>1.7</target> </configuration> <version>3.3</version> </plugin> <plugin> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-maven-plugin</artifactId> <version>1.3.2</version> <dependencies> <dependency> <groupId>com.oracle</groupId> <artifactId>ojdbc6</artifactId> <version>11.2.0.4.0</version> </dependency> </dependencies> <configuration> <!--配置文件的路径--> <configurationFile>src/main/resources/generatorConfig.xml</configurationFile> <overwrite>true</overwrite> </configuration> </plugin> </plugins> </pluginManagement> </build> </project>
2.在项目的classpath中(src/main/resources目录下)新增generatorConfig.xml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> <context id="test" targetRuntime="MyBatis3"> <plugin type="org.mybatis.generator.plugins.EqualsHashCodePlugin"></plugin> <plugin type="org.mybatis.generator.plugins.SerializablePlugin"></plugin> <plugin type="org.mybatis.generator.plugins.ToStringPlugin"></plugin> <commentGenerator> <!-- 这个元素用来去除指定生成的注释中是否包含生成的日期 false:表示保护 --> <!-- 如果生成日期,会造成即使修改一个字段,整个实体类所有属性都会发生变化,不利于版本控制,所以设置为true --> <property name="suppressDate" value="true" /> <!-- 是否去除自动生成的注释 true:是 : false:否 --> <property name="suppressAllComments" value="false" /> </commentGenerator> <!--数据库链接URL,用户名、密码 --> <jdbcConnection driverClass="oracle.jdbc.OracleDriver" connectionURL="jdbc:oracle:thin:@127.0.0.1:1521:MYDEV" userId="SCHOOLMALL" password="hcxyjie2010"> </jdbcConnection> <javaTypeResolver> <!-- This property is used to specify whether MyBatis Generator should force the use of java.math.BigDecimal for DECIMAL and NUMERIC fields, --> <property name="forceBigDecimals" value="false" /> </javaTypeResolver> <!-- 生成模型的包名和位置 --> <javaModelGenerator targetPackage="com.zouwj.study.model" targetProject="E:\javastudy\MyBatis\schoolmall\src\main\java"> <property name="enableSubPackages" value="true" /> <property name="trimStrings" value="true" /> </javaModelGenerator> <!-- 生成映射文件的包名和位置 --> <sqlMapGenerator targetPackage="mapper" targetProject="E:\javastudy\MyBatis\schoolmall\src\main\resources"> <property name="enableSubPackages" value="true" /> </sqlMapGenerator> <!-- 生成DAO的包名和位置 --> <javaClientGenerator type="XMLMAPPER" targetPackage="com.zouwj.study.mapper" targetProject="E:\javastudy\MyBatis\schoolmall\src\main\java"> <property name="enableSubPackages" value="true" /> </javaClientGenerator> <!-- 要生成哪些表 --> <table tableName="t_student_info" domainObjectName="StudentInfo" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table> </context> </generatorConfiguration>
3.如果是在eclipse 中,选择pom.xml文件,击右键先择Run AS——>Maven Build… ——>在Goals框中输入:mybatis-generator:generate
如果在命令行输入Maven命令即可,注意:一定是当前项目目录下运行该命令。
4.刷新当前项目,就可以看到自动生成的代码了,注意代码生成的路径
