使用aop和BindingResult进行参数验证

@Component
@Aspect
public class ParameterValidAop implements Ordered{


    @Around("execution(* com.zxgeo.seplatform.directory.web.*Controller.*(..)) && args(..,bindingResult)")
    public Object validateParam(ProceedingJoinPoint pjp, BindingResult bindingResult) throws Throwable {
        if (bindingResult.hasErrors()){
　　　　　　//错误信息
            StringBuffer sb = new StringBuffer();
            List<FieldError> fieldErrors = bindingResult.getFieldErrors();
            for (FieldError fieldError : fieldErrors) {
                sb.append(fieldError.getField()+":"+fieldError.getDefaultMessage()+";");
            }
            throw new ProjectException(sb.toString());
        }
        return pjp.proceed();
    }

    @Override
    public int getOrder() {
        return 10;
    }
}
