maven使用mybatis-generator自动生成代码

1.pom.xml配置，需要用mysql-connector-java和mybatis-generator-core两个包

	<build>
		 <!--给出构建过程中所用到的插件。  -->
			<plugins>
				<!-- 指定jdk这样就不会每次update后又回到1.5的版本 -->
				<plugin>
					<groupId>org.apache.maven.plugins</groupId>
					<artifactId>maven-compiler-plugin</artifactId>
					<version>2.3.2</version>
					<configuration>
						<source>1.8</source>
						<target>1.8</target>
					</configuration>
				</plugin>
				<plugin>
					<groupId>org.mybatis.generator</groupId>
					<artifactId>mybatis-generator-maven-plugin</artifactId>
					<version>1.3.2</version>
					<dependencies>
						<dependency>
							<groupId>mysql</groupId>
							<artifactId>mysql-connector-java</artifactId>
							<version>5.1.35</version>
						</dependency>
					</dependencies>
					<configuration>
						<configurationFile>src/main/resources/generator.xml</configurationFile>
						<verbose>true</verbose>
						<overwrite>true</overwrite>
					</configuration>
				</plugin>
			</plugins>
	</build>
	<!--下载所需要用到的包  -->
	<dependencies>
		<dependency>
			<groupId>mysql</groupId>
			<artifactId>mysql-connector-java</artifactId>
			<version>5.1.35</version>
		</dependency>
		<dependency>
			<groupId>org.mybatis.generator</groupId>
			<artifactId>mybatis-generator-core</artifactId>
			<version>1.3.2</version>
		</dependency>
	</dependencies>

2.在resources下添加generatorConfig.xml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>
     <!-- 数据库驱动包位置 -->
     <!-- <classPathEntry location="D:\MavenRepository\repository\jar\mysql-connector-java-5.1.7-bin.jar" />  -->
     <!-- <classPathEntry location="C:\oracle\product\10.2.0\db_1\jdbc\lib\ojdbc14.jar" />-->
     <context id="DB2Tables" 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>
             <property name="suppressAllComments" value="true" />
         </commentGenerator>
         <!-- 数据库链接URL、用户名、密码 -->
          <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://localhost:3306/test" userId="root" password="671354"> 
         </jdbcConnection>
         <javaTypeResolver>
             <property name="forceBigDecimals" value="false" />
         </javaTypeResolver>
         <!-- 生成实体类的包名和位置，这里配置将生成的实体类放在com.smxy.lq.pojo这个包下 -->
         <javaModelGenerator targetPackage="com.smxy.lq.pojo" targetProject="src\main\java\">                                                                   
             <property name="enableSubPackages" value="true" />
             <property name="trimStrings" value="true" />
         </javaModelGenerator>
         <!-- 生成的SQL映射文件包名和位置，这里配置将生成的SQL映射文件放在com.smxy.lq.mapping这个包下 -->
         <sqlMapGenerator targetPackage="com.smxy.lq.mapping" targetProject="src\main\java\">
             <property name="enableSubPackages" value="true" />
         </sqlMapGenerator>
         <!-- 生成DAO的包名和位置，这里配置将生成的dao类放在com.smxy.lq.dao这个包下 -->
         <javaClientGenerator type="XMLMAPPER" targetPackage="com.smxy.lq.dao" targetProject="src\main\java\">
             <property name="enableSubPackages" value="true" />
         </javaClientGenerator>
         <!-- 要生成那些表(更改tableName和domainObjectName就可以) -->
         <table tableName="tab_user" domainObjectName="User" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false" />
     </context>
</generatorConfiguration>

3.右键项目Run As>>Maven build,Goals中填入mybatis-generator:generate然后运行run就可以了

效果图：

到此结束

---------------------------------------------------------------------------------------------------------------------------------

导出Maven项目的依赖包右击pom.xml文件，选择Run As--》Maven build

输入dependency:copy-dependencies     然后点击Run

在当前项目的目录的“targed/dependency”下就可以看见。
