Mybatis generator生成Service，Controller,添加批量新增数据接口(基于mybatis-generator-1.3.5源码修改)

其他 2018-11-30 12:11:23 阅读次数: 0

　　　　好久记录笔记，这段时间做政府的项目，数据录入系统基本都是通过excel导入，且数据量大，许多也是单表的录入，这就有很多可以通用的代码，如controller，service层的那一套都是可以代码生成，添加了一个数据库批量添加接口(目前只支持oracle)，

代码是基于mybatis-generator-1.3.5源码修改后的，具体的源码解析，后面等项目上线后，再好好整理一下，这里就粗鲁的记录如何使用。

　　mybatis-generator.xml 配置文件

        <!--数据库链接地址账号密码-->
        <jdbcConnection driverClass="oracle.jdbc.driver.OracleDriver"
                        connectionURL="jdbc:oracle:thin:@127.0.0.1:1521:test"
                        userId="xxxx" password="xxxx" >
            <!--开启读取数据库注释：为了把注释写到相对应的注解里面-->
            <property name="remarksReporting" value="true"></property>
        </jdbcConnection>
        <javaTypeResolver>
            <property name="forceBigDecimals" value="false"/>
        </javaTypeResolver>
        <!--生成Model类存放位置-->
        <javaModelGenerator targetPackage="com.shsoft.platform.domain" targetProject="src/main/java">
            <property name="enableSubPackages" value="true"/>
            <!--设置注解，%s占位符,读取数据库字段注释（多个注解用;分隔)，一个占位符读取数据库字段注释，第二数据库字段排序-->
            <property name="annotation" value="@Excel(name = &quot;%s&quot;, fixedIndex = %s);@ApiParam(value = &quot;%s&quot;)"/>
            <!--设置注解需要的包路径，多个用,分隔-->
            <property name="annotationTargetPackage" value="cn.afterturn.easypoi.excel.annotation.Excel,io.swagger.annotations.ApiParam"/>
        </javaModelGenerator>
        <!--生成映射文件存放位置-->
        <sqlMapGenerator targetPackage="com.shsoft.platform.dao.mapper" targetProject="src/main/java">
            <property name="enableSubPackages" value="true"/>
        </sqlMapGenerator>
        <!--生成Dao类存放位置-->
        <javaClientGenerator type="XMLMAPPER" targetPackage="com.shsoft.platform.dao" targetProject="src/main/java">
            <property name="enableSubPackages" value="true"/>
        </javaClientGenerator>

        <!--生成service,serviceImpl-->
        <javaServiceGenerator targetPackage="com.shsoft.platform.service" targetProject="src/main/java"
                              implementationPackage="com.shsoft.platform.service">
        </javaServiceGenerator>
        
        <!--生成controller-->
        <javaControllerGenerator targetPackage="com.shsoft.platform.ctrl" targetProject="src/main/java">
            <property name="superClass" value="com.shsoft.platform.ctrl.BaseController"></property>
        </javaControllerGenerator>

        <!--生成对应表及类名,添加:enableInsertBatch(是否生成批量添加语句,目前只支持oracle),enableInsertBatchIgnore:批量添加语句中忽略的字段-->
        <table tableName="SYSTEM_NOTICE" domainObjectName="SystemNotice" enableCountByExample="true" enableUpdateByExample="true"
               enableDeleteByExample="true" enableSelectByExample="true" selectByExampleQueryId="false" enableInsertBatch="true"
               enableListParam="true">
            <property name="enableInsertBatchIgnore" value="createDt"></property>
        </table>
    </context>
</generatorConfiguration>

执行生成代码

最后生成 InsertBatch

生成service

生成controller:添加excel导入导出接口(基于easypoi导入导出)
