java异常统一处理

标签:tps play cli void https Servle bsp let autowired 一般系统抛出的错误不含错误代码,出去部分的404,500,400之外,我们如果想吧错误代码定义的更细致,就需要自己继承RuntimeExeption这个类后,重新定义构造方法定义自己的错误信息。 使用一个handler来判定我们try。。。catch。。。的错误是我们已知的错误还是未知的,如果已知,返回错误,未知返回未知错误和记录日志,留着以后查找错误。 这样我们就不用返回日志到前端了,让用户感觉很奇怪。 但是这时候调用接口出现异常,我们怎么来判断是前端还是后端造成的问题呢。这时候就要用aop进行拦截 java异常统一处理 标签:tps play cli void https Servle bsp let autowired 原文地址:https://www.cnblogs.com/zhumiao/p/9633209.htmlpublic class DescribeException extends RuntimeException{
