Tomcat启动报Error listenerStart错误 | "beans" 必须匹配 DOCTYPE 根 "null" | java.lang.ref

liujjun

　　maven打包发布工程时，发布上去却报错FAIL - Deployed application at context path /ch but context failed to start
　　在服务器上重启tomcat，只看到报错：
　　严重: Error listenerStart
一月 13, 2015 9:59:05 上午 org.apache.catalina.core.StandardContext startInternal
严重: Context [/PMF] startup failed due to previous errors
　　没有具体的错误信息，网上搜索Error listenerStart，说重新配置下log的打印可以看到具体信息，见：http://xpenxpen.iteye.com/blog/1545648
　　之后就看到具体错误是

　　搜索“文档根元素 "beans" 必须匹配 DOCTYPE 根 "null"。” 看了很多帖子才找到答案。。见：http://blog.iyunv.com/trwhoya/article/details/4312776
　　知道是spring的版本问题，于是将1.2.6的spring.jar包换成2.5.6的。。于是问题又来了。。报错：

　　之后是搜索cause by那个“ java.lang.reflect.MalformedParameterizedTypeException”才总算解决了问题，见：http://dikar.iteye.com/blog/1452680
　　最下面一楼的评论，依旧是spring的版本问题，于是maven配置文件pom.xml里删掉spring的那个依赖就好了。
