Use the Mybatis-generator plugin to quickly generate code in idea

1. First build the maven project, add the plugin

<build>
        <plugins>
  <plugin>
                <!--Mybatis-generator plugin in pom.xml to automatically generate Mapper and POJO-->
                <groupId>org.mybatis.generator </groupId>
                <artifactId>mybatis-generator-maven-plugin</artifactId>
                <version>1.3.2</version>
                <configuration>
                   <!--location of configuration file-->
                    <configurationFile>maven_myibatis/mybatis-generator -config.xml</configurationFile>
                    <verbose>true</verbose>
                    <overwrite>true</overwrite>
                </configuration>
                <executions>
                    <execution>
                        <id>Generate MyBatis Artifacts</id>
                        <goals>
                            <goal>generate</goal>
                        </goals>
                    </execution>
                </executions>
                <dependencies>
                    <dependency>
                        <groupId>org.mybatis.generator</groupId>
                        <artifactId>mybatis-generator-core</artifactId>
                        <version>1.3.2</version>
                    </dependency>
                </dependencies>
            </plugin>
</plugins>
    </build>

2. Create a folder maven_myibatis under the project name, add the configuration file mybatis-generator-config.xml with the following content
<?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>

    <!-- full path to local database driver jar package- ->
    <classPathEntry location="E:/myIdea/mylib/ojdbc6.jar"/>

    <context id="context" targetRuntime="MyBatis3">
        <commentGenerator>
            <property name="suppressAllComments" value="false"/>
            < property name="suppressDate" value="true"/>
        </commentGenerator>

        <!-- Database configuration-->
        <jdbcConnection driverClass="oracle.jdbc.OracleDriver"
                        connectionURL="jdbc:oracle:thin:@192.168.1.4:1521:yunboce"
                        userId="t4444" password="6666s"/>

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

        <!-- 实体类生成的位置 -->
        <javaModelGenerator targetPackage="com.tms.bean.system" targetProject=".\src\main\java">
            <property name="enableSubPackages" value="false"/>
            <property name="trimStrings" value="true"/>         <!-- *Location of the Mapper.xml file-->
        </javaModelGenerator>


        <sqlMapGenerator targetPackage="com.tms.mapper.system" targetProject=".\src\main\java">
            <property name="enableSubPackages" value="false"/>
        </sqlMapGenerator>

        <!-- Mapper 接口文件的位置 -->
        <javaClientGenerator targetPackage="com.tms.mapper.system" targetProject=".\src\main\java" type="XMLMAPPER">
            <property name="enableSubPackages" value="false"/>
        </javaClientGenerator>

        <!-- 相关表的配置 -->
        <table tableName="manager"
               enableCountByExample="false"
               enableDeleteByExample="false"
               enableSelectByExample="false"
               enableUpdateByExample="false"/>
    </context>
</generatorConfiguration>

Note: the location of mybatis-generator-config.xml is determined according to the address defined by pom.xml

3. Click "maven projects" on the right, and then click "Mybatis-generator" to automatically generate code
