我创建了一个自定义注释
@Documented
@Constraint(validatedBy = CheckGranularityValidator.class)
@Target( { ElementType.PARAMETER} )
@Retention(RetentionPolicy.RUNTIME)
public @interface CheckGranularity {
String message() default "Duration has to be a multiple of granularity";
Class<?>[] groups() default {};
Class<? extends Payload>[] payload() default {};
}
使用这样的验证器
public class CheckGranularityValidator implements ConstraintValidator<CheckGranularity, AssetCostsRequest> {
@Override
public void initialize(final CheckGranularity constraintAnnotation) {
}
@Override
public boolean isValid(final AssetCostsRequest value, final ConstraintValidatorContext context) {
return value.getRange().getDuration() % value.getGranularity() == 0;
}
}
我尝试在RestController中使用它
@RestController
public class CalcApiController extends CalcApi {
@Override
public ResponseEntity<String> calcProfitability(@Valid @CheckGranularity @RequestBody final AssetCostsRequest assetCostsRequest) {
return ResponseEntity.ok("Works");
}
我通过编写测试尝试使用此批注:
@Test
public void calcTest() {
final AssetCostsRequest request = new AssetCostsRequest()
.setRange(new TimeRange(100L, 200L))
.setGranularity(26L);
given()
.contentType(ContentType.JSON)
.body(request)
.when()
.post("/calc")
.then()
.statusCode(HttpStatus.SC_BAD_REQUEST);
}
AssetCostsRequest的相关部分:
public class AssetCostsRequest {
@JsonProperty
@NotNull
private TimeRange range;
@JsonProperty
@NotNull
private Long granularity = 30L;
...getters & setters
}
测试方法返回200。当我尝试在isValid
方法中设置一个断点时,在运行测试时没有命中该断点。我尝试更改批注的顺序,摆脱@Valid
,更改@Target
类中的CheckGranularity
,没有任何帮助。我正在使用RestAssured进行测试。
我该如何做,以便我的注释正确验证了一个参数?
答案 0 :(得分:0)
将ElementType.TYPE
的目标更改为@CheckGranularity
,并在AssetCostsRequest
上直接添加$arr = [['contact_email' => 'a@a.com'], ['contact_email' => 'a@a.com'], ['contact_email' => 'b@a.com']];
$result = [];
array_map(function ($item) use (&$result) {
$result[$item['contact_email']] = $item;
}, $arr);
print_r($result);
