最近在做办公自动化的项目,在Spring与Struts2整合的时候遇到了问题,现在将遇到的问题和解决方案分享.
问题1:

解决说明:
我的JDK版本为1.8的,而项目引用的spring的jar包版本低,不兼容JDK1.8,所以需要重新下载新的jar包,我选择了4.0的spring包,引入了几个spring的jar包引入以后,出现了另外一个问题.
java.lang.ClassNotFoundException: org.springframework.web.context.ContextLoaderListener at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1858) at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1701) at org.apache.catalina.core.DefaultInstanceManager.loadClass(DefaultInstanceManager.java:504) at org.apache.catalina.core.DefaultInstanceManager.loadClassMaybePrivileged(DefaultInstanceManager.java:486) at org.apache.catalina.core.DefaultInstanceManager.newInstance(DefaultInstanceManager.java:113) at org.apache.catalina.core.StandardContext.listenerStart(StandardContext.java:4984) at org.apache.catalina.core.StandardContext.startInternal(StandardContext.java:5584) at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:147) at org.apache.catalina.core.ContainerBase$StartChild.call(ContainerBase.java:1572) at org.apache.catalina.core.ContainerBase$StartChild.call(ContainerBase.java:1562) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745)
这个问题是由于没有添加spring-web的jar包.添加了以后就可以解决了.
附上我引用的spring的jar包的截图.引用了这些jar包以后,就可以启动tomcat了
