1、com.baomidou.mybatisplus.extension.plugins.pagination.Page的使用

Mapper层

.xml文件：

<select id="page" resultType="com.sample.pass.contract.model.vo.ContractMaterialVo">selectsum (total) as totalMoney,cm.*,c.party_a_name,c.party_b_name,c.classify_name as classifyName,c.type_name as typeName,c.code,c.name as contractName,c.business_unit_name as businessUnitNamefromcontract_material as cmINNER JOIN contract c on cm.contract_id = c.idwherecm.del_flag = 0and c.del_flag = 0and (c.status = 10 or c.status = 20)<if test="name != null and name != ''">and find_in_set(cm.name,#{name})</if><if test="classifyName != null and classifyName != ''">and c.classify_name = #{classifyName}</if><if test="typeName != null and typeName != ''">and c.type_name like concat('%',#{typeName} ,'%')</if><if test="partyName != null and partyName != ''">and (find_in_set(c.party_a_name,#{partyName}) or find_in_set(c.party_b_name,#{partyName}))</if><if test="startTime != null and startTime != '' and endTime != null and endTime != ''">and DATE_FORMAT(cm.create_time,'%Y%m%d') between #{startTime} and #{endTime}</if>group by cm.name, cm.specification, cm.brand, cm.unit_name<if test="conditions != null and conditions != '' and conditions == 'number'">order by cm.number desc</if><if test="conditions != null and conditions != '' and conditions == 'total'">order by cm.total desc</if><if test="conditions == null or conditions == ''">order by cm.total desc</if>
</select>

List<ContractMaterialVo> page(@Param("query") Query query, @Param("name") String name, @Param("conditions") String conditions, @Param("classifyName") String classifyName, @Param("typeName") String typeName, @Param("partyName") String partyName, @Param("startTime") String startTime, @Param("endTime") String endTime);

Service层

service接口层：

Page<ContractMaterialVo> contractMaterialList(Query query, String name, String conditions, String classifyName, String typeName, String partyName, String time);

service实现类：

@Override
public Page<ContractMaterialVo> contractMaterialList(Query query, String name, String conditions, String classifyName, String typeName, String partyName, String time) {String startTime = "",endTime = "";if(time != null && !"".equals(time)){startTime = time.split("-")[0];endTime = time.split("-")[1];}List<ContractMaterialVo> list = contractMaterialMapper.page(query, name, conditions, classifyName, typeName, partyName, startTime, endTime);return query.setRecords(list);
}

Controller层

@RequestMapping(value = "/contract-page")
@ApiOperation(httpMethod = "GET", value = "合同分析分页条件查询")
public R<Page<Contract>> contractPage(@ApiParam(value = "合同金额最高",required = false) @RequestParam(value = "conditions",required = false) String conditions,@ApiParam(value = "合同分类",required = false) @RequestParam(value = "classifyName",required = false) String classifyName,@ApiParam(value = "合同类型",required = false) @RequestParam(value = "typeName",required = false) String typeName,@ApiParam(value = "签约单位",required = false) @RequestParam(value = "partyName",required = false) String partyName,@ApiParam(value = "签约单位",required = false) @RequestParam(value = "part",required = false) String part,@ApiParam(value = "模版名称",required = false) @RequestParam(value = "time",required = false) String time,@ApiParam(value = "页码",required = true) @RequestParam("page") Integer page,@ApiParam(value = "每页个数",required = true) @RequestParam("pageSize") Integer pageSize) {Page<Contract> contractPage = contractService.analysePage(new Query(new HashMap<String, Integer>() {{put("page", page);put("limit", pageSize);}}), conditions, classifyName, typeName, partyName, part, time);return R.ok(contractPage);
}

2、mysql的find_in_set函数

find_in_set(str,strlist)函数

第一个参数：可以是字段也可以是字段中的一个数据

第二个参数：可以使字段集合也可以是以逗号作为分割根据的字符串

查询的结果集为： str在strlist中的结果集
