Java 关键词跟范围查询
作者：互联网
1、页面功能实现，只看 实体类、基类、跟mapper.xml 就可以了
二、实体类 （该实体用继承关系 QwBaseEntity类）
package com.ruoyi.enterprise.domain;
import com.fasterxml.jackson.annotation.JsonFormat;
import com.ruoyi.common.annotation.Excel;
import lombok.Data;
import java.util.Date;
/**
* 信息对象 qw_enterprise
*
* @author ruoyi
* @date 2022-05-23
*/
@Data
public class QwEnterprise extends QwBaseEntity
{
private static final long serialVersionUID = 1L;
/** 企业信息ID */
private Integer id;
/** 地区ID */
private String regionId;
/** 企业名称 */
private String enterpriseName;
/** 登记状态 （0在业/存续 1清算 2迁入 3迁出 4停业 5撤销 6吊销 7注销 8歇业 9责令关闭） */
private String status;
/** 法定代表人 */
private String legalName;
/** 注册资金 */
private Double money;
/** 注册资本 */
private String registeredCapital;
/** 成立时间 */
@JsonFormat(pattern = "yyyy-MM-dd")
private Date establishTime;
/** 参保人数 */
private Integer insuredPeople;
/** 经营范围 */
private String articleContent;
}
基类：组装成前端所需要的格式（部分使用类部类）
package com.ruoyi.enterprise.domain;
import lombok.Data;
import java.io.Serializable;
import java.time.LocalDate;
import java.util.List;
/**
* 基础信息Entity基类
*
* @author ruoyi
*/
@Data
public class QwBaseEntity implements Serializable
{
private static final long serialVersionUID = 1L;
/** 关键词 */
private String keyword;
/** 登记状态 */
private List<Long> statusIds;
/** 地区ID数组 */
private List<Long> regionIds;
/** (参保人数)最小值\最大值 */
private List<InsuredPeople> personsList;
/** (成立时间)开始日期 至 结束日期 */
private List<EstablishTime> timeList;
/** (注册资本)最小值\最大值 */
private List<RegisteredCapital> moneyList;
@Data
public static class InsuredPeople{
private Integer min;
private Integer max;
}
@Data
public static class EstablishTime{
private LocalDate beginTime;
private LocalDate endTime;
}
@Data
public static class RegisteredCapital{
private Integer min;
private Integer max;
}
}
三、Mapper接口
package com.ruoyi.enterprise.mapper;
import com.ruoyi.enterprise.domain.QwEnterprise;
import org.apache.ibatis.annotations.Param;
import java.util.List;
/**
* Mapper接口
*
* @author ruoyi
* @date 2022-05-23
*/
public interface QwEnterpriseMapper
{
/**
* 查询企业信息列表
* @param qwEnterprise 企业信息
* @return 企业信息集合
*/
public List<QwEnterprise> selectQwEnterpriseList(@Param("param")QwEnterprise qwEnterprise, @Param("regionIds") Long regionIds);
}
四：Mapper.xml SQL语句（关键），通过 foreach 实现范围检索
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<!-- 将下列SQL语句绑定 dao层对应接口 -->
<mapper namespace="com.ruoyi.enterprise.mapper.QwEnterpriseMapper">
<resultMap type="QwEnterprise" id="QwEnterpriseResult">
<result property="id" column="id" />
<result property="region_id" column="regionId" />
<result property="enterpriseName" column="enterprise_name" />
<result property="status" column="status" />
<result property="legalName" column="legal_name" />
<result property="money" column="money" />
<result property="registeredCapital" column="registered_capital" />
<result property="establishTime" column="establish_time" />
<result property="approvalTime" column="approval_time" />
<result property="province" column="province" />
<result property="city" column="city" />
<result property="area" column="area" />
<result property="phonenumber" column="phonenumber" />
<result property="morePhonenumber" column="more_phonenumber" />
<result property="email" column="email" />
<result property="moreEmail" column="more_email" />
<result property="creditCode" column="credit_code" />
<result property="taxpayerNumber" column="taxpayer_number" />
<result property="registrationNumber" column="registration_number" />
<result property="organizationCode" column="organization_code" />
<result property="insuredPeople" column="insured_people" />
<result property="enterpriseType" column="enterprise_type" />
<result property="industry" column="industry" />
<result property="usedBeforeName" column="used_before_name" />
<result property="englishName" column="english_name" />
<result property="websiteUrl" column="website_url" />
<result property="businessAddress" column="business_address" />
<result property="reportAddress" column="report_address" />
<result property="articleContent" column="article_content" />
</resultMap>
<sql id="selectQwEnterpriseVo">
select id, region_id, enterprise_name, status, legal_name, money, registered_capital, establish_time, approval_time,
province, city, area, phonenumber, more_phonenumber,email, more_email, credit_code, taxpayer_number,
registration_number, organization_code, insured_people, enterprise_type,industry, used_before_name,
english_name, website_url, business_address, report_address, article_content
from qw_enterprise
</sql>
<select id="selectQwEnterpriseList" parameterType="QwEnterprise" resultMap="QwEnterpriseResult">
<include refid="selectQwEnterpriseVo"/>
<where>
<if test="param.keyword != null and param.keyword != ''"> <!-- 关键词搜索 -->
AND (enterprise_name like CONCAT('%',#{param.keyword},'%')
or legal_name = #{param.keyword}
or phonenumber = #{param.keyword}
or credit_code = #{param.keyword}
or taxpayer_number = #{param.keyword}
or registration_number = #{param.keyword}
or business_address like CONCAT('%',#{param.keyword},'%'))
</if>
<if test="param.statusIds != null">
AND status in
<foreach collection="param.statusIds" index="index" item="id" open="(" separator="," close=")"> <!-- 登记状态 -->
#{id}
</foreach>
</if>
<if test="regionIds != null"> <!-- 地区ID集合 -->
AND (region_id like CONCAT('%',#{regionIds},'%'))
</if>
<if test="param.personsList != null "> <!-- 参保人数【范围】 -->
AND
<foreach collection="param.personsList" item="num" open="(" separator="or" close=")">
(insured_people >= #{num.min} and insured_people <= #{num.max})
</foreach>
</if>
<if test="param.timeList != null "> <!-- 成立时间【范围】 -->
AND
<foreach collection="param.timeList" item="time" open="(" separator="or" close=")">
(establish_time >= #{time.beginTime} and establish_time <= #{time.endTime})
</foreach>
</if>
<if test="param.moneyList != null "> <!-- 注册资本【范围】 -->
AND
<foreach collection="param.moneyList" item="num" open="(" separator="or" close=")">
(money >= #{num.min} and money <= #{num.max})
</foreach>
</if>
</where>
</select>
</mapper>
五：Service接口
package com.ruoyi.enterprise.service;
import com.ruoyi.enterprise.domain.QwEnterprise;
import java.util.List;
/**
* Service接口
*
* @author ruoyi
* @date 2022-05-23
*/
public interface IQwEnterpriseService {
/**
* 查询企业信息列表
* @param qwEnterprise 企业信息
* @return 企业信息集合
*/
public List<QwEnterprise> selectQwEnterpriseList(QwEnterprise qwEnterprise);
}
六：Service业务层处理
package com.ruoyi.enterprise.service.impl;
import com.ruoyi.common.exception.ServiceException;
import com.ruoyi.common.utils.StringUtils;
import com.ruoyi.enterprise.domain.QwEnterprise;
import com.ruoyi.enterprise.mapper.QwEnterpriseMapper;
import com.ruoyi.enterprise.service.ITableAreaService;
import com.ruoyi.enterprise.service.IQwEnterpriseService;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.ArrayList;
import java.util.List;
/**
* Service业务层处理
*
* @author ruoyi
* @date 2022-05-23
*/
@Service
public class QwEnterpriseServiceImpl implements IQwEnterpriseService {
private static final Logger log = LoggerFactory.getLogger(QwEnterpriseServiceImpl.class);
@Autowired
private QwEnterpriseMapper qwEnterpriseMapper;
@Autowired
private ITableAreaService tableAreaService;
/**
* 查询企业信息列表
*
* @param qwEnterprise 企业信息
* @return 企业信息
*/
@Override
public List<QwEnterprise> selectQwEnterpriseList(QwEnterprise qwEnterprise) {
List<QwEnterprise> qwEnterprises = new ArrayList<>();
//判断选择的地区ID数组不为空，就根据前端返回的参数查询
if (qwEnterprise.getRegionIds() != null) {
qwEnterprise.getRegionIds().forEach(regionId -> {
qwEnterprises.addAll(qwEnterpriseMapper.selectQwEnterpriseList(qwEnterprise, regionId));
});
} else {
qwEnterprises.addAll(qwEnterpriseMapper.selectQwEnterpriseList(qwEnterprise, null));
}
return qwEnterprises;
}
}
七：控制层处理 （返回的格式为 JSON格式，通过注解：@RequestBody）
package com.ruoyi.enterprise.controller;
import com.ruoyi.common.core.controller.BaseController;
import com.ruoyi.common.core.domain.AjaxResult;
import com.ruoyi.common.core.page.TableDataInfo;
import com.ruoyi.common.utils.poi.ExcelUtil;
import com.ruoyi.enterprise.domain.QwEnterprise;
import com.ruoyi.enterprise.service.IQwEnterpriseService;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;
import org.springframework.web.multipart.MultipartFile;
import javax.servlet.http.HttpServletResponse;
import java.util.List;
/**
* 企业信息Controller
*
* @author ruoyi
* @date 2022-05-23
*/
@Api(tags = "信息==》接口")
@RestController
@RequestMapping("/enterprise")
@Slf4j
public class QwEnterpriseController extends BaseController
{
@Autowired
private IQwEnterpriseService qwEnterpriseService;
/**
* 查询企业信息列表
*/
@ApiOperation("信息查询接口")
@PostMapping("/list")
public TableDataInfo list(@RequestBody QwEnterprise qwEnterprise)
{
startPage();
List<QwEnterprise> list = qwEnterpriseService.selectQwEnterpriseList(qwEnterprise);
return getDataTable(list);
}
}
注：TableDataInfo 表格分页数据对象 ；getDataTable web层通用数据处理；参考【若依】封装类
