这是我的存储库：
@Query( "SELECT new com.app.gsc.entities.ListeBI(lm.listeDeCriteres.designation,count(*) as totalNumber,lm.ficheDeMission.dateEtHeurDeDepart) from ListeDeControleDetailsMission lm where lm.boolDepart=false OR lm.ficheDeMission.codeDeFicheDeMission=:CodeMission GROUP BY lm.listeDeCriteres.designation,DATE(lm.ficheDeMission.dateEtHeurDeDepart)" )
List<ListeBI> getIncidentDepart( @Param( "CodeMission" ) Integer missId );
和我的控制者：
@RequestMapping( value = "admin/dashboard/getIncidentDepart/{codeMission}", method = RequestMethod.GET )
public Reponse getIncidentDepart( HttpServletResponse response, @PathVariable Integer codeMission ) { // entêtes
CorsController.getIncidentDepart( response, codeMission );
if ( messages != null ) {
return new Reponse( -1, messages );
}
List<ListeBI> listeBIs = null;
try {
listeBIs = application.getIncidentDepart( codeMission );
} catch ( Exception e ) {
return new Reponse( 5, Static.getErreursForException( e ) );
}
return new Reponse( 0, Static.getMapForMissionIncidents( listeBIs ) );
}
我的问题是：第一个问题我想传递codeMission作为选择变量，我不知道我怎么能把它但我会解释，如果我在控制器中传递codeMission变量请求应该工作，如果我不在控制器中传递codeMission变量请求也应该工作，我怎么能这样做，而且我也不确定请求中的条件是否工作正常：
其中lm.boolDepart = false或lm.ficheDeMission.codeDeFicheDeMission =：CodeMission
答案 0 :(得分：0)
关于JPQL问题
这里：
where lm.boolDepart=false OR lm.ficheDeMission.codeDeFicheDeMission=:CodeMission
如果您的:CodeMission参数值为not null，则您的过滤符会按预期运行，但如果值为null，则会过滤:codeMission==null条件并且不是你想要的。
要解决这两种情况（null :CodeMission param和not null :CodeMission param），请尝试：
where lm.boolDepart=false OR
(:CodeMission is null OR lm.ficheDeMission.codeDeFicheDeMission=:CodeMission)
具体地说：
如果100填充:CodeMission作为where lm.boolDepart=false OR
(lm.ficheDeMission.codeDeFicheDeMission=:100)
的值，则会产生：
null如果:CodeMission的值为where lm.boolDepart=false OR
(null is null)
，则会产生以下结果：
codeMission关于Rest配置问题
如果您使用Spring 4和Java 8，则可以@RequestMapping( value = "admin/dashboard/getIncidentDepart/{codeMission}", method = RequestMethod.GET )
public Reponse getIncidentDepart( HttpServletResponse response, @PathVariable Optional<Integer> codeMission ) {
...
}
