maven逆向工程的使用

逆向工程的配置

1.在pom.xml文件中导入mybatis-generator-core的依赖

 	<dependency>
	    <groupId>org.mybatis.generator</groupId>
	    <artifactId>mybatis-generator-core</artifactId>
		<version>1.3.5</version>
	</dependency>

2. 在pom.xml文件中配置mybatis-generator-core 插件

 <plugin>
        <groupId>org.mybatis.generator</groupId>
        <artifactId>mybatis-generator-maven-plugin</artifactId>
        <version>1.3.2</version>
    <configuration>
        <configurationFile>
        	src/main/resources/generatorConfig.xml
        </configurationFile>
        <verbose>true</verbose>
        <overwrite>true</overwrite>
    </configuration>
		<dependencies>
          <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>5.1.37</version>
          </dependency>
        </dependencies>
  </plugin>

3. 准备mybatis逆向工程所需要的配置文件 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>
    <!-- 有Example查询条件内容 -->
    <context id="testTables" targetRuntime="MyBatis3">
        <commentGenerator >
            <!-- 是否去除自动生成的注释 true：是 ： false:否 -->
            <property name="suppressAllComments" value="true" />
        </commentGenerator>

        <!--数据库连接的信息：驱动类、连接地址、用户名、密码 -->
        <jdbcConnection
                driverClass="com.mysql.jdbc.Driver"
                connectionURL="jdbc:mysql://localhost:3306/crmpro"
                userId="root"
                password="1234">
        </jdbcConnection>

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

        <!-- targetProject:生成Entity类的路径 -->
        <javaModelGenerator targetProject=".\src\main\java" targetPackage="com.worksystem.emp.bean">
            <!-- enableSubPackages:是否让schema作为包的后缀 -->
            <property name="enableSubPackages" value="false" />
            <!-- 从数据库返回的值被清理前后的空格 -->
            <property name="trimStrings" value="true" />
        </javaModelGenerator>

        <!-- targetProject:XXXMapper.xml映射文件生成的路径 -->
        <sqlMapGenerator targetProject=".\src\main\java" targetPackage="com.worksystem.emp.dao">
            <!-- enableSubPackages:是否让schema作为包的后缀 -->
            <property name="enableSubPackages" value="false" />
        </sqlMapGenerator>

        <!-- targetPackage：Mapper接口生成的位置 -->
        <javaClientGenerator type="XMLMAPPER" targetProject=".\src\main\java" targetPackage="com.worksystem.emp.dao">
            <!-- enableSubPackages:是否让schema作为包的后缀 -->
            <property name="enableSubPackages" value="false" />
        </javaClientGenerator>
		   <!-- 指定需要生成类在数据库中的表名和要生成的类名 -->
        <table tableName="employee" 	domainObjectName="Employee"/>

    </context>
</generatorConfiguration>
