// 错误写法
List<Map<String, String>> smokeBriefList = smokeBriefService.findSmokeBriefDataByDate(startTime, endTime);
List<Map<String,String>> findSmokeBriefDataByDate(@Param(“startTime”) String startTime, @Param(“endTime”) String endTime);

// 正确写法
List<Map<String, Object>> smokeBriefList = smokeBriefService.findSmokeBriefDataByDate(startTime, endTime);
List<Map<String,Object>> findSmokeBriefDataByDate(@Param(“startTime”) String startTime, @Param(“endTime”) String endTime);

start_time字段数据库数据类型是java.sql.Data，返回Map接收查询结果，接收时使用了List<Map<String,String>>接收结果集；list集合转为json时，时间戳转为字符串会报错，需要将接受结果集改为List<Map<String,Object>>。

xml文件：

<select id="findSmokeBriefDataByDate" resultType="java.util.HashMap">
    select
      p.prj_name,b.build_name,e.start_time,e.end_time,
      s.total_cases,s.total_time,s.fail_cases,s.skip_cases,s.pass_rate,s.downtime,s.flashtime
    from
      tb_project p inner join tb_build b
      on p.id = b.prj_id
      inner join tb_test_event e
      on b.id = e.build_id
      inner join tb_report_smoke_brief s
      on e.id = s.test_event_id
    where
      e.testtype_id = 2 and start_time &gt;= #{startTime} and end_time &lt; #{endTime}
    order by e.start_time
</select>

解决date传递前端变成时间戳问题

在application.properties文件中添加：

#spring.jackson.serialization.write-dates-as-timestamps=true
spring.jackson.time-zone=GMT+8
spring.jackson.date-format=yyyy-MM-dd HH:mm:ss
