[英]What is wrong in this Spring Boot controller method annotation? (the path of the request is defined at class level and the path variable at method)
[英]Pagination in Spring Boot via path variable - Requested path variable is not present in Controller request mapping annotations
我们正在尝试借助此功能进行分页

使用请求参数很好,但是当我们尝试使用Path variables
时,它给出异常说
Controller 请求映射注释中不存在请求的路径变量 {destUserId}
以下是我们尝试过的方法
方法一:使用@PathVariable
@RequestMapping(method = RequestMethod.GET, value = "/cf/{destUserId}")
@ResponseBody
public PagedResponse<SystemStock> croudFundReport(@PathVariable(name = "destUserId") String eventId,
@Conjunction (value = {
@Or(value = @Spec(path = "metaType", params = {"meta_type"}, spec = Equal.class))},
and = @Spec(path = "destUserId", pathVars = "destUserId", spec = Equal.class)) Specification<UserData> spec) {
return null;
}
方法 2:不使用 @PathVariable
@RequestMapping(method = RequestMethod.GET, value = "/cf/{destUserId}")
@ResponseBody
public PagedResponse<SystemStock> croudFundReport(@Conjunction (value = {
@Or(value = @Spec(path = "metaType", params = {"meta_type"}, spec = Equal.class))},
and = @Spec(path = "destUserId", pathVars = "destUserId", spec = Equal.class)) Specification<UserData> spec) {
return null;
}
方法 3:仅使用路径和 @PathVariable 的 RequestMapping
@RequestMapping("/cf/{destUserId}")
@ResponseBody
public PagedResponse<SystemStock> croudFundReport(@PathVariable(name = "destUserId") String eventId,
@Conjunction (value = {
@Or(value = @Spec(path = "metaType", params = {"meta_type"}, spec = Equal.class))},
and = @Spec(path = "destUserId", pathVars = "destUserId", spec = Equal.class)) Specification<UserData> spec) {
return null;
}
方法 4:仅使用路径而不使用 @PathVariable 的 RequestMapping
@RequestMapping("/cf/{destUserId}")
@ResponseBody
public PagedResponse<SystemStock> croudFundReport(@Conjunction (value = {
@Or(value = @Spec(path = "metaType", params = {"meta_type"}, spec = Equal.class))},
and = @Spec(path = "destUserId", pathVars = "destUserId", spec = Equal.class)) Specification<UserData> spec) {
return null;
}
方法 5:仅使用路径的 RequestMapping,不带 @PathVariable,不带 @Conjunction
@RequestMapping("/cf/{destUserId}")
@ResponseBody
public PagedResponse<SystemStock> croudFundReport(@Spec(path = "destUserId", pathVars = "destUserId", spec = Equal.class) Specification<UserData> spec) {
return null;
}
方法6:没有@PathVariable,没有@Conjunction 的GetMapping
@GetMapping(path = "/cf/{destUserId}", produces = MediaType.APPLICATION_JSON_VALUE)
@ResponseBody
public PagedResponse<SystemStock> croudFundReport(@Spec(path = "destUserId", pathVars = "destUserId", spec = Equal.class) Specification<UserData> spec) {
return null;
}
参考
问题是我们可以将PathVariable
作为方法参数访问,但是当我们尝试在上述情况下在pathVars
中指定它时,执行没有到达我们的 Controller 并且我们得到了相同的上述异常。 有什么帮助吗?
我注意到您只在最后一个示例中使用了 GetMapping 的一件事。 有使用 RequestMapping 的理由吗?
是否有不使用 [JPA 分页][https://www.baeldung.com/jpa-pagination] 的特定原因?
您是否尝试过以下操作?
@GetMapping(path = "/cf/{destUserId}", produces = MediaType.APPLICATION_JSON_VALUE)
public PagedResponse<SystemStock> croudFundReport( @PathVariable(name = "destUserId") final String destUserId) {
// TODO implementation
}
