Spring RequestBody可选验证

Question

@ResponseBody
@RequestMapping(value = API.UPDATE_CLIENT, produces = ResponseType.JSON, method = RequestMethod.POST)
public HashMap update(
        @PathVariable(value = "id")int id,
        @RequestBody Client clientData
) {

    clientLogic.update(id, clientData);

    ....
}

Answer 1

您可以使用Spring的@validated，并使用groups。如果我理解正确，一些值会被设置，另一些不会。因此，问题只在于空检查。您希望暂时允许空值。

public interface NullAllowed {}

@Email(groups = NullAllowed.class) //email allows null, so you are good
private String email;

@NotNull //skip this check - not assigned to NullAllowed.class
@Size(min=1, groups = NullAllowed.class)
private String name;

public HashMap update(
    @PathVariable(value = "id")int id,
    @Validated(NullAllowed.class) @RequestBody Client clientData)

只有标记为NullAllowed.class的检查才会被验证。
