Question

整合SSH报错

java.lang.IllegalStateException: Cannot initialize context because there is already a root application context present - check whether you have multiple ContextLoader* definitions in your web.xml!
估计是什么错误呢？
这个我也能看懂啦
我在web。xml加了格这

<servlet>
<servlet-name>context</servlet-name>
<servlet-class>
org.springframework.web.context.ContextLoaderServlet
</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>

是和监听器冲突了吗

Answer 1

IllegalStateException:环境没有处于请求操作所要求的适当状态下。
不能初始化环境，因为已经有一个application-context存在，检查你的web.xml文件看是否定义了多个ContextLoader.
