解决tomcat启动报错:一个或多个listeners启动失败问题

tomcat启动报错:一个或多个listeners启动失败

这种错误一般是在javaweb项目中使用监听器时出现的。

造成的原因时

没有在web.xml文件中配置全局参数。

如图：

具体原理

当我们使用spring自带的工具类WebApplicationContextUtils时，在它的方法ContextLoaderListener方法中，会在web应用启动时就加载配置文件（为了防止每次执行业务都加载一次配置文件和spring容器，节约内存），所以把每次要加载的配置文件抽取出来，做成一个全局参数，得到后，继而创建上下文对象Application，并将其存储到最大的域ServletContext中，从而可以在任何地方获得并使用Application对象。

**注：**如果是自己写的监听器，上图中不需要写classpath：

启动tomcat服务器时出现错误

启动Tomcat服务器时出现如下错误：

解决方式

是因为Tomcat服务器启动多次，导致服务器的端口被占用，关闭服务器，然后重新启动就可以了。
