採用Mybatis-Generator生成mapper

Step1 : 配置pom.xml,

<build>

       <plugins>

           <plugin>

               <groupId>org.mybatis.generator</groupId>

               <artifactId>mybatis-generator-maven-plugin</artifactId>

               <version>1.3.2</version>

               <configuration>

                   <configurationFile>src/main/resources/generator/generatorConfig.xml</configurationFile>

                   <verbose>true</verbose>

                   <overwrite>true</overwrite>

               </configuration>

               <dependencies>

                   <dependency>

                       <groupId>org.mybatis.generator</groupId>

                       <artifactId>mybatis-generator-core</artifactId>

                       <version>1.3.2</version>

                   </dependency>

               </dependencies>

           </plugin>

       </plugins>

    </build>

Step2 : 添加配置文件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>
    <classPathEntry location="D:/lib/mysql-connector-java-5.1.18.jar"/>
    <context id="mymysql" targetRuntime="MyBatis3">
        <commentGenerator>
            <property name="suppressDate" value="false"/>
            <!-- 是否去除自動生成的註釋 true：是 ： false:否 -->
            <property name="suppressAllComments" value="true"/>
        </commentGenerator>


        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                        connectionURL="jdbc:mysql://localhost:3306/db_ssm"
                        userId="ssm_1"
                        password="ssm_1"/>


        <javaModelGenerator targetPackage="com.cn.raysun.persist.entity"
                            targetProject="../spmvc-demo1/src/main/java">
            <property name="enableSubPackages" value="true"/>
            <property name="trimStrings" value="true"/>
        </javaModelGenerator>


        <sqlMapGenerator targetPackage="com.cn.raysun.persist.mapper"
                         targetProject="../spmvc-demo1/src/main/resources/">
            <property name="enableSubPackages" value="true"/>
        </sqlMapGenerator>


        <javaClientGenerator targetPackage="com.cn.raysun.persist.mapper"
                             targetProject="../spmvc-demo1/src/main/java" type="XMLMAPPER">
            <property name="enableSubPackages" value="true"/>
        </javaClientGenerator>


        <table tableName="t_user" domainObjectName="User"
               enableCountByExample="false" enableUpdateByExample="false"
               enableDeleteByExample="false" enableSelectByExample="false"
               selectByExampleQueryId="false">
        </table>
    </context>
</generatorConfiguration>

Step3 : 在工程上運行maven命令 mvn mybatis-generator:generate
