Spring——Artifact spring:war exploded: Error during artifact deployment. See server log for details

Tomcat加载问题

修改了一个类的名字，使用idea自动修改这个类的名字，修改完之后就报错：

Artifact storage:war exploded: Error during artifact deployment. See server log for details

解决方法1：重新生成war包

1.在tomcat中，将项目的war包删除

2. 在idea->project Settings中将war包删除，并重新打包。

3.在tomcat中，重新加载war包

方法2：重新生成web.xml

查看日志，发现WEB-INF下的web.xml报错。删除web.xml中的配置内容，重新配置xml

<?xml version="1.0" encoding="UTF-8"?>
