eclipse执行mybatis逆向工程，自动生成代码

操作工具：eclipse

准备工作：在resources目录下增加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>
	<!-- 制度MySQL驱动包的路径，别放在中文路径xia -->
	<classPathEntry
		location="E:\dormitory\dormitory_maven\mysql\mysql-connector-java\5.1.38\mysql-connector-java-5.1.38.jar" />
	<context id="context1">
		<commentGenerator>
			<!--是否取消注销 -->
			<property name="suppressAllComments" value="true" />
		</commentGenerator>
		<jdbcConnection driverClass="com.mysql.jdbc.Driver"
			connectionURL="jdbc:mysql://localhost:3306/parkingdb?characterEncoding=utf-8"
			userId="root" password="123456">
		</jdbcConnection>
		<!-- 所生成的实体类的位置默认资源包src -->
		<javaModelGenerator
			targetPackage="com.st.eleventh.model" targetProject="src/main/java">
			<!-- 是否在当前路径下新加一层schema,eg：fase路径com.st.eleventh.user.model， true:com.st.eleventh.user.model.[schemaName] -->
			<property name="enableSubPackages" value="false" />
			<!-- 是否针对string类型的字段在set的时候进行trim调用 -->
			<property name="trimStrings" value="true" />
		</javaModelGenerator>
		<!--所生成的sqlMapper的映射文件位置，默认资源包src -->
		<sqlMapGenerator
			targetPackage="com.st.eleventh.dao.mapper.parking"
			targetProject="src/main/resources">
			<!-- 是否在当前路径下新加一层schema,eg：fase路径com.st.eleventh.user.model， true:com.st.eleventh.user.model.[schemaName] -->
			<property name="enableSubPackages" value="false" />
		</sqlMapGenerator>
		<!--配置到接口生成信息 -->
		<javaClientGenerator
			targetPackage="com.st.eleventh.dao" type="XMLMAPPER"
			targetProject="src/main/java">
			<!-- 是否在当前路径下新加一层schema,eg：fase路径com.st.eleventh.user.model， true:com.st.eleventh.user.model.[schemaName] -->
			<property name="enableSubPackages" value="false" />
		</javaClientGenerator>


		<!-- 配置表信息 -->

		<table schema="parkingdb" tableName="t_cars"
			domainObjectName="ParkingCars" enableCountByExample="false"
			enableUpdateByExample="false" enableDeleteByExample="false"
			enableSelectByExample="false" selectByExampleQueryId="false">
			<property name="useActualColumnNames" value="true" />
		</table>

		<table schema="parkingdb" tableName="t_ctms"
			domainObjectName="Customer" enableCountByExample="false"
			enableUpdateByExample="false" enableDeleteByExample="false"
			enableSelectByExample="false" selectByExampleQueryId="false">
			<property name="useActualColumnNames" value="true" />
		</table>

		<table schema="parkingdb" tableName="t_disobey_record"
			domainObjectName="PayRecord" enableCountByExample="false"
			enableUpdateByExample="false" enableDeleteByExample="false"
			enableSelectByExample="false" selectByExampleQueryId="false">
			<property name="useActualColumnNames" value="true" />
		</table>

		<table schema="parkingdb" tableName="t_group"
			domainObjectName="ParkGroup" enableCountByExample="false"
			enableUpdateByExample="false" enableDeleteByExample="false"
			enableSelectByExample="false" selectByExampleQueryId="false">
			<property name="useActualColumnNames" value="true" />
		</table>

		<table schema="parkingdb" tableName="t_monthly_report"
			domainObjectName="MthReport" enableCountByExample="false"
			enableUpdateByExample="false" enableDeleteByExample="false"
			enableSelectByExample="false" selectByExampleQueryId="false">
			<property name="useActualColumnNames" value="true" />
		</table>

		<table schema="parkingdb" tableName="t_parecord"
			domainObjectName="ParkRecord" enableCountByExample="false"
			enableUpdateByExample="false" enableDeleteByExample="false"
			enableSelectByExample="false" selectByExampleQueryId="false">
			<property name="useActualColumnNames" value="true" />
		</table>

		<table schema="parkingdb" tableName="t_parking"
			domainObjectName="Parking" enableCountByExample="false"
			enableUpdateByExample="false" enableDeleteByExample="false"
			enableSelectByExample="false" selectByExampleQueryId="false">
			<property name="useActualColumnNames" value="true" />
		</table>

		<table schema="parkingdb" tableName="t_space"
			domainObjectName="Space" enableCountByExample="false"
			enableUpdateByExample="false" enableDeleteByExample="false"
			enableSelectByExample="false" selectByExampleQueryId="false">
			<property name="useActualColumnNames" value="true" />
		</table>

		<table schema="parkingdb" tableName="t_worker"
			domainObjectName="Worker" enableCountByExample="false"
			enableUpdateByExample="false" enableDeleteByExample="false"
			enableSelectByExample="false" selectByExampleQueryId="false">
			<property name="useActualColumnNames" value="true" />
		</table>


	</context>
</generatorConfiguration>

2.在pom.xml增加相应数据库依赖，和在build中加入mybatis插件。

<!-- 添加mybatis依赖 -->
<dependency>
  <groupId>org.mybatis</groupId>
  <artifactId>mybatis</artifactId>
  <version>${mybatis.version}</version>
</dependency>
<!-- 添加mybatis/spring整合包依赖 -->
<dependency>
  <groupId>org.mybatis</groupId>
  <artifactId>mybatis-spring</artifactId>
  <version>1.3.0</version>
</dependency>
<!-- 添加mysql驱动依赖 -->
<dependency>
  <groupId>mysql</groupId>
  <artifactId>mysql-connector-java</artifactId>
  <version>${mysql-driver.version}</version>
</dependency>

<build>
		
			<plugins>


				<!--mybatis逆向工程 -->
				<plugin>
					<groupId>org.mybatis.generator</groupId>
					<artifactId>mybatis-generator-maven-plugin</artifactId>
					<version>1.3.2</version>
					<configuration>
						<verbose>true</verbose>
						<overwrite>true</overwrite>
					</configuration>
				</plugin>
				
			</plugins>
		
	</build>

3.右键点击项目名--》Run As-->Maven build-->在Goals中添加mybatis-generator:generate，点击apply然后run。运行完后刷新项目，就有自动生成的代码了。

 

注：如果刷新后没有自动生成代码，或者run时console控制台报错，请检查：

1.generatorConfig.xml中你mysql驱动包的路径是否正确

2.generatorConfig.xml中你数据库连接信息，数据库名是否正确

3.pom.xml中是否加入了要用到的依赖包，加入了可以右键点击项目名-->Maven-->Update  Project进行更新下。
