mybatis_generator自动生成entity、mapper、xml代码

参考 https://www.cnblogs.com/yjmyzz/p/4210554.html，本身在IDEA上实际操做了一遍

一、使用mysql设计好数据库以后，在pom.xml文件中添加插件plugin，确认pom.xml中有以下代码

<plugin>
   <groupId>org.mybatis.generator</groupId>
   <artifactId>mybatis-generator-maven-plugin</artifactId>
   <version>1.3.2</version>
   <configuration>
      <configurationFile>${basedir}/src/main/resources/generator/mybatis-generator-config.xml</configurationFile>
      <overwrite>true</overwrite>
      <verbose>true</verbose>
   </configuration>
   <dependencies>
      <dependency>
         <groupId>mysql</groupId>
         <artifactId>mysql-connector-java</artifactId>
         <version>${mysql.version}</version>
      </dependency>
      <dependency>
         <groupId>tk.mybatis</groupId>
         <artifactId>mapper</artifactId>
         <version>3.4.0</version>
      </dependency>
   </dependencies>
</plugin>

二、找到mybatis-generator-config.xml文件，修改数据库相关内容

<?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>
     <!-- 本地数据库驱动程序jar包的全路径 需更改成本机的数据库驱动的版本-->  <classPathEntry location="C:\Users\Administrator\.m2\repository\mysql\mysql-connector-java\5.1.44\mysql-connector-java-5.1.44.jar"/>

    <context id="Mysql" targetRuntime="MyBatis3Simple" defaultModelType="flat">
        <property name="beginningDelimiter" value="`"/>
        <property name="endingDelimiter" value="`"/>

        <plugin type="tk.mybatis.mapper.generator.MapperPlugin">
            <property name="mappers" value="com.jusheng.jeeboot.system.BaseMapper"/>
        </plugin>
 

<!-- 改成要使用的数据库URL、用户名和密码 -->

< jdbcConnection driverClass ="com.mysql.jdbc.Driver" connectionURL ="jdbc:mysql://192.168.31.**/***" userId ="root" password ="***" > </ jdbcConnection >

<!-- 自动生成的entity、xml和mapper文件的存放位置-->

< javaModelGenerator targetPackage ="com.jusheng.jeeboot.entity" targetProject ="src/main/java" /> < sqlMapGenerator targetPackage ="mapping" targetProject ="src/main/resources" /> < javaClientGenerator targetPackage ="com.jusheng.jeeboot.dao" targetProject ="src/main/java" type ="XMLMAPPER" />

<!-- 改成要使用的数据库的表名称 -->

< table tableName ="sys_user" > <!--mysql 配置--> < generatedKey column ="id" sqlStatement ="select UUID() " identity ="true" /> <!--<property name="rootClass" valcom.jusheng.jeeboot.entity.base.BaseEntitytity"/>--> <!--oracle 配置--> <!--<generatedKey column="id" sqlStatement="select SEQ_{1}.nextval from dual" identity="false" type="pre"/>--> </ table > </ context > </ generatorConfiguration >

三、利用mavenProject自动构建生成文件

进入Maven Projects视图

右键mybatis-generator→Run

即在自定义的路径下生成指定表的对应的entity、mapper和xml文件
