没有找到 @RestController 和 @RequestMapping 的映射
No mapping found with @RestController an @RequestMapping
我有以下控制器
@RestController("/person")
public class PersonController {
@Autowired
PersonService personService;
@RequestMapping(value = "/list",
method = RequestMethod.GET,
produces = MediaType.APPLICATION_JSON_VALUE
)
public List<PersonNode> getPersons(){
return personService.getList();
}
}

但是，当我参考 http://localhost:8080/rest/list 时，我得到了预期的人员列表。
我想在 class 级别的人员和方法级别的“列表”中使用 @RestController 时参考 http://localhost:8080/rest/person/list。如何做到这一点？
您应该将@RequestMapping 添加到您的控制器Class
@RestController
@RequestMapping("/person")
public class PersonController {
@Autowired
PersonService personService;
@RequestMapping(value = "/list", method = RequestMethod.GET, produces = MediaType.APPLICATION_JSON_VALUE)
public List<PersonNode> getPersons(){
return personService.getList();
}
}
