我实施自己的验证,以检查springapp中容量od预算实体的值。代码如下:
注解:
@Retention(RetentionPolicy.RUNTIME)
@Target({ElementType.FIELD, ElementType.PARAMETER})
@Constraint(validatedBy = {CapacityValidator.class})
public @interface Capacity {
String message() default "Capacity over limit. Maximum value 9999";
Class<?>[] groups() default {};
Class<? extends Payload>[] payload() default {};
}
电容校验器等级:
import com.example.CapacityGurdian.annotation.Capacity;
import javax.validation.ConstraintValidator;
import javax.validation.ConstraintValidatorContext;
public class CapacityValidator implements ConstraintValidator<Capacity, Float> {
private final static float MAX_CAPACITY_VALUE = 9999;
@Override
public boolean isValid(Float value, ConstraintValidatorContext constraintValidatorContext) {
return MAX_CAPACITY_VALUE < value;
}
}
然后我在rest控制器中使用它,如下所示:
@RestController
@RequestMapping("/budgets")
@Validated
@Api(
value = "GrantsBudgetController",
tags = "Capacity controller for budget"
)
public class BudgetController {
BudgetService budgetService;
@Autowired
public BudgetController(BudgetService budgetService) {
this.budgetService = budgetService;
}
@PutMapping({"/budget/{id}/capacity/{value}"})
@ApiOperation(value = "Updates capacity od specified budget by id",
notes = "Adds value to capacity of specified budget",
response = Budget.class)
public ResponseEntity<Budget> updateBudget(
@ApiParam(value = "Id of updated budget") @PathVariable @NotNull Long id,
@ApiParam(value = "Value which will be added to current capacity") @PathVariable
@Capacity Float value) {
return ResponseEntity.ok(budgetService.addCapacityById(id,value));
}
这段代码应该可以工作,但这次不行。然后我决定通过在字符串属性上添加@size(max=3)和@notempty来检查标准javax.validations是否有效。不幸的是,它也不起作用。我在intellij中检查了注解处理器,它设置得很好。有人知道如何打开我的验证吗?
