java.lang.IllegalStateException: No MethodInvocation found: Check that an AOP invocation is in progress,
and that the ExposeInvocationInterceptor is upfront in the interceptor chain. Specifically,
note that advices with order HIGHEST_PRECEDENCE will execute before ExposeInvocationInterceptor! 

当切点service方法抛出异常后，切面类LogInterceptor 的throwing方法会正常执行，但Controller里却无法捕获ValidateException 异常，通过捕获Exception异常后，报出文上错误信息，经查看源码发现，是源码ExposeInvocationInterceptor类中抛出了新异常IllegalStateException，源码如下：

<bean id="logInterceptor" class="xx.xxx.xxx.LogInterceptor"></bean>
<aop:config><aop:aspect id="logAspectSYS" ref="logInterceptor" order="1"><aop:after-throwing method="throwing" throwing="ex" pointcut="execution(public * xx.xxx.xxx..*.*(..))" /></aop:aspect>
</aop:config>

切面类如下：

public class LogInterceptor {static Log logger = LogFactory.getLog(LogInterceptor.class);public void throwing(JoinPoint joinPoint, Throwable ex) {StackTraceElement[] stack =  ex.getStackTrace();logger.error("异常信息：" + (ex.getMessage() == null ? "" : ex.getMessage()));  logger.error("{");logger.error("\t" + ex.getClass().getName());for(int i = 0; i < stack.length; i++){logger.error("\t" + stack[i]);}logger.error("}");}
}

Service切点方法如下：

public int saveFinancialPlan(String applyIds,Double amount,Integer days,Double    interest,Integer raiseDays,Integer releaseType,Date releaseTime)  throws ValidateException{throw new ValidateException("发生异常了");
}

Controller方法如下

@RequestMapping(value = "saveFinancialPlan")
public @ResponseBody OperateResult saveFinancialPlan(String applyIds,Double amount,Integer days,Double interest,Integer raiseDays,Integer releaseType,Date releaseTime, Model model){try {financePlanService.saveFinancialPlan(applyIds,amount,days,interest,raiseDays,releaseType,releaseTime);} catch (ValidateException e) {return new OperateResult(OperateResultType.Error,e.getMessage());}return new OperateResult(OperateResultType.Success);
}

研究很久也没弄清原因。可以肯定，配置方面没有问题。

<context:component-scan base-package="xx.xx.xxx" />  <!--扫描所有注解的包-->
<aop:aspectj-autoproxy/>                             <!--打开aop注解-->   

切面类如下：

@Component
@Aspect
public class LogInterceptor {static Log logger = LogFactory.getLog(LogInterceptor.class);@Pointcut("execution(public * xx.xxx.xxx..*.*(..))")public void pointcut(){}@AfterThrowing(pointcut = "pointcut()",throwing = "ex")public void throwing(JoinPoint joinPoint, Throwable ex) {StackTraceElement[] stack =  ex.getStackTrace();logger.error("异常信息：" + (ex.getMessage() == null ? "" : ex.getMessage()));  logger.error("{");logger.error("\t" + ex.getClass().getName());for(int i = 0; i < stack.length; i++){logger.error("\t" + stack[i]);}logger.error("}");}
}

如此，就解决了问题，再也没有报上文的错误，切面类也很好的实现了功能。

<aop:aspect id="logAspectSYS" ref="logInterceptor" order="1">
