反射抛出异常，如何确定异常类型
参考代码：
private String invokeMethod(ForeignService foreignService, Map<String, Object> paramMap) throws Exception {
Object resultObj = null;
try {
Object bean = SpringUtil.getBean(foreignService.getHandlerService());
Class beanClass = bean.getClass();
Method method = beanClass.getMethod(foreignService.getHandlerMethod(),ForeignService.class, Map.class);
if (Assert.checkParam(paramMap)) {
resultObj = method.invoke(bean, foreignService,paramMap);
}
} catch (Exception e) {
LOG.error("调用外部接口反射异常,foreignServiceId={}", foreignService.getId());
throw e;
}
return (String)resultObj;
}
外部调用以上方法时， try catch 需要这样写：
} catch (Exception ex) {
ex.printStackTrace();
resultLevel = RuleLevelEnum.ERROR.getStatus();
LOG.error("xxx：{}", ex.getMessage());
resultDetailMap.put("errMsg", "xxx");
if(ex instanceof InvocationTargetException) {
InvocationTargetException targetEx = (InvocationTargetException)ex;
Throwable t = targetEx .getTargetException();
if(t instanceof BussinessException) {
// xxx
resultLevel = RuleLevelEnum.WARNING.getStatus();
BussinessException bussinessEx = (BussinessException)t;
if (bussinessEx.getErrCode() == BussinessExceptionEnum.INTERFACE_TIMEOUT.getCode()) {
interfaceExceptionFlag = Boolean.TRUE;
resultDetailMap.put("errMsg", "xxx");
}
if (bussinessEx.getErrCode() == BussinessExceptionEnum.INTERFACE_EXCEPTION.getCode()) {
interfaceExceptionFlag = Boolean.TRUE;
resultDetailMap.put("errMsg", "xxx");
}
}
}
}
