将servlet资源发布在tomcat服务器上之后,明明没有错误,确一直不通过,仔细检查了n遍之后,才发现原来是注解重复

修改前:

Caused by: java.lang.IllegalStateException: 启动子级时出
Caused by: java.lang.IllegalStateException: 启动子级时出

修改后:

Caused by: java.lang.IllegalStateException: 启动子级时出
Caused by: java.lang.IllegalStateException: 启动子级时出

结束:

在这次的错误中让我明白编写程序的时候一定要细致再细致,同时我将再网上搜到的同样问题给大家截个图,希望对大家有所帮助。
