类 MethodValidator

java.lang.Object

cn.ponfee.commons.constrain.FieldValidator

cn.ponfee.commons.constrain.MethodValidator

public abstract class MethodValidator
extends FieldValidator

 方法参数校验：拦截方法中包含@Constraints注解的方法
 e.g.：
    1.开启spring切面特性：
    2.编写子类：
        ＠Component ＠Aspect
        public class TestMethodValidator extends MethodValidator {

            ＠Around(
                value = "execution(public * cn.ponfee.xxx.service.impl..*Impl..*(..)) && ＠annotation(cst)", 
                argNames = "pjp,cst"
            )
            ＠Override
            public Object constrain(ProceedingJoinPoint pjp, Constraints cst) throws Throwable {
                return super.constrain(pjp, cst);
            }

            ＠Override
            protected Object handleFailure(Class returnType, String errMsg) {
                if (BaseResult.class.isAssignableFrom(returnType)) {
                    return BaseResult.failure(errMsg);
                }
                return super.handleFailure(returnType, errMsg);
            }

        }
