Mybatis-generator生成Service和Controller

2018-12-03 09:26:11来源：博客园阅读 ()

　　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。

1:mybatis-generator.xml 配置文件

<?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>
    <context id="DB2Tables" targetRuntime="MyBatis3">
        <!--<plugin type="net.coderbee.mybatis.batch.BatchStatementHandler"></plugin>
        <plugin type="net.coderbee.mybatis.batch.BatchParameterHandler"></plugin>-->
        <commentGenerator>
            <property name="suppressDate" value="true"/>
            <property name="suppressAllComments" value="true"/>
        </commentGenerator>
        <!--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>

2:执行生成代码

2-1:最后生成 InsertBatch

<insert id="insertBatch" parameterType="java.util.List">
    insert into FIXED_ASSETS_INDICATOR (ID, ORDER_MARK, COUNT_TIME, 
      CITY, CITY_CODE, FIXED_INVESTMENT_TOTAL, 
      FIXED_INVESTMENT_SPEED_UP, FOLK_INVESTMENT_TOTAL, 
      FOLK_INVESTMENT_SPEED_UP, REALTY_INVESTMENT_TOTAL, 
      REALTY_INVESTMENT_SPEED_UP, EMPLOYMENT_INVESTMENT_TOTAL, 
      EMPLOYMENT_INVESTMENT_SPEED_UP, TECHNOLOGY_INVESTMENT_TOTAL, 
      TECHNOLOGY_INVESTMENT_SPEED_UP, INFRASTRUCTURE_TOTAL, 
      INFRASTRUCTURE_SPEED_UP, HIGH_TECH_TOTAL, 
      HIGH_TECH_SPEED_UP, MANUFACTURING_TOTAL, 
      MANUFACTURING_SPEED_UP)
    <foreach close=")" collection="list" item="item" open="(" separator="UNION">
      SELECT #{item.id,jdbcType=VARCHAR}, #{item.orderMark,jdbcType=DECIMAL}, #{item.countTime,jdbcType=TIMESTAMP}, 
        #{item.city,jdbcType=VARCHAR}, #{item.cityCode,jdbcType=VARCHAR}, #{item.fixedInvestmentTotal,jdbcType=DECIMAL}, 
        #{item.fixedInvestmentSpeedUp,jdbcType=FLOAT}, #{item.folkInvestmentTotal,jdbcType=DECIMAL}, 
        #{item.folkInvestmentSpeedUp,jdbcType=FLOAT}, #{item.realtyInvestmentTotal,jdbcType=DECIMAL}, 
        #{item.realtyInvestmentSpeedUp,jdbcType=FLOAT}, #{item.employmentInvestmentTotal,jdbcType=DECIMAL}, 
        #{item.employmentInvestmentSpeedUp,jdbcType=FLOAT}, #{item.technologyInvestmentTotal,jdbcType=DECIMAL}, 
        #{item.technologyInvestmentSpeedUp,jdbcType=FLOAT}, #{item.infrastructureTotal,jdbcType=DECIMAL}, 
        #{item.infrastructureSpeedUp,jdbcType=FLOAT}, #{item.highTechTotal,jdbcType=DECIMAL}, 
        #{item.highTechSpeedUp,jdbcType=FLOAT}, #{item.manufacturingTotal,jdbcType=DECIMAL}, 
        #{item.manufacturingSpeedUp,jdbcType=FLOAT} FROM DUAL
    </foreach>
  </insert>

2-2:生成service

public class FixedAssetsIndicatorServiceImpl implements FixedAssetsIndicatorService {
    @Autowired
    private FixedAssetsIndicatorMapper fixedAssetsIndicatorMapper;

    public int insertBatch(List<FixedAssetsIndicator> list) {
        if(list != null && list.size() > 0 ){
            FixedAssetsIndicatorExample fixedAssetsIndicatorExample = new FixedAssetsIndicatorExample();
            fixedAssetsIndicatorExample.createCriteria().andCountTimeEqualTo(list.get(0).getCountTime());
            fixedAssetsIndicatorMapper.deleteByExample(fixedAssetsIndicatorExample);
            return fixedAssetsIndicatorMapper.insertBatch(list);
        }
        return 0;
    }
    public PageInfo<FixedAssetsIndicator> list(ListFixedAssetsIndicatorParam param) {
        FixedAssetsIndicatorExample example = new FixedAssetsIndicatorExample();
        if(param.getCountTime() != null){
            example.createCriteria().andCountTimeEqualTo(param.getCountTime());
        }
        PageHelper.startPage(param.getPageNum(), param.getPageSize());
        example.setOrderByClause("ORDER_MARK");
        List<FixedAssetsIndicator> fromDB = fixedAssetsIndicatorMapper.selectByExample(example);
        PageInfo pageInfo = new PageInfo(fromDB);
        return pageInfo;
    }

    public FixedAssetsIndicator get(String id) {
        return fixedAssetsIndicatorMapper.selectByPrimaryKey(id);
    }

    public void save(FixedAssetsIndicator toDB) {
        fixedAssetsIndicatorMapper.insertSelective(toDB);
    }

    public void delete(String id) {
        fixedAssetsIndicatorMapper.deleteByPrimaryKey(id);
    }

    public void update(FixedAssetsIndicator toDB) {
        fixedAssetsIndicatorMapper.updateByPrimaryKeySelective(toDB);
    }
}

2-3:生成controller:添加excel导入导出接口(基于easypoi导入导出)

@Slf4j
@Controller
@RequestMapping("/fixedAssetsIndicator")
@Api(description = "能源投资统计科:分市固定资产投资主要指标")
