我直接使用@RequestMapping
中使用的CustomRepository
公开了存储库方法。 CrudRepository
提供的默认方法与@RequestMapping
除delete(ID id)
之外的工作正常。
给出以下代码
@RepositoryRestResource(path = "/ces/data/reports")
@RequestMapping("/ces/data/reports")
@Api(value="reports")
public interface IReportRepository<S> extends CrudRepository<Report,Integer> {
@CrossOrigin
@RequestMapping(path="/delete/{id}",method = RequestMethod.GET)
void delete(@PathVariable Integer id);
}
当我们使用spring boot运行它时会抛出错误。 创建bean时,日志打印模糊方法删除。

以下是docs
有时您可能希望为特定资源编写自定义处理程序。要利用Spring Data REST的设置,消息转换器,异常处理等,请使用@RepositoryRestController注释而不是标准的Spring MVC @Controller或@RestController
因此,为了自定义delete方法,您需要创建一个控制器,例如ReportRepositoryController:
@RepositoryRestController
public class ReportRepositoryController {
@Inject
private IReportRepository repository;
@RequestMapping(method = RequestMethod.GET, value = "/ces/data/reports/delete/{id}")
@ResponseBody
public ResponseEntity<?> deleteReport(@PathVariable Long id) {
repository.delete(id);
return ResponseEntity.ok(HttpStatus.NO_CONTENT);
}
}
并从IReportRepository中删除delete
方法:
@RepositoryRestResource(path = "/ces/data/reports")
@Api(value="reports")
public interface IReportRepository<S> extends CrudRepository<Report,Integer> {
}

CrudRepository已经公开了此表单上的删除方法
因此,如果您定义void delete(@PathVariable Integer id);
,则会报告错误。
定义另一个签名的一种方法是在另一个休息控制器中包装
