Java 求助

public Boolean valid() 试试

那你就进到 validatorFactory.validate 看看是怎么回事

@Belmode 试了，不行

```java
public final <T> Set<ConstraintViolation<T>> validate(T object, Class<?>... groups) {
Contracts.assertNotNull(object, Messages.MESSAGES.validatedObjectMustNotBeNull());
ValidationContext<T> validatiOnContext= this.getValidationContextBuilder().forValidate(object);
if (!validationContext.getRootBeanMetaData().hasConstraints()) {
return Collections.emptySet();
} else {
ValidationOrder validatiOnOrder= this.determineGroupValidationOrder(groups);
ValueContext<?, Object> valueCOntext= ValueContext.getLocalExecutionContext(this.parameterNameProvider, object, validationContext.getRootBeanMetaData(), PathImpl.createRootPath());
return this.validateInContext(validationContext, valueContext, validationOrder);
}
}

public <T> ValidationContext<T> forValidate(T rootBean) {
Class<T> rootBeanClass = rootBean.getClass();
return new ValidationContext(this.constraintValidatorManager, this.messageInterpolator, this.constraintValidatorFactory, this.traversableResolver, (ExecutableParameterNameProvider)null, this.clockProvider, this.failFast, rootBean, rootBeanClass, this.beanMetaDataManager.getBeanMetaData(rootBeanClass), (Executable)null, (Object[])null, (Object)null);
}

```
反射拿了对象的类信息

public class AssertTrueValidator implements ConstraintValidator<AssertTrue, Boolean> {

@Override
public boolean isValid(Boolean bool, ConstraintValidatorContext constraintValidatorContext) {
//null values are valid
return bool == null || bool;
}

}

public interface ConstraintValidator<A extends Annotation, T> {
xxxx
}
-- 注解中指定的方法名是 isValid

报错信息贴一些呗

因为 valid 是一个普通方法，isValid 是 boolean 类型的 getter 方法
校验只校验 getter 方法（印象里好像还有字段

@gitdoit 多谢多谢
