使用maven多模块来构建系统时,spring初始化报错的问题
最近在实验maven结构的maven工程时,碰到一个问题,springbean总是初始化失败:

直接打成war包,然后放置到tomat中运行没有问题,但是在eclipse中使用Tomcat7:run报错。
一开始非常不理解:从网络上排查,说是bean多次定义或者bean Name重复定义导致,但是由于我能在tomcat中正常运行,因此可以排除。
个人感觉是maven的某个地方配置有问题:
尝试在pom文件中加入:
<plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-resources-plugin</artifactId> <version>2.6</version> <configuration> <overwrite>true</overwrite> </configuration></plugin>
发现没有效果:
实验使用jettyplugin插件:
<plugin> <groupId>org.mortbay.jetty</groupId> <artifactId>jetty-maven-plugin</artifactId> <version>8.1.15.v20140411</version> </plugin>
发现还是没有效果。
最后在修改applicationcontext.xml后,发现跟有缓存一样,不起作用,进一步排查发现:
在WEB-INF中:有classes目录和lib目录。(从其他项目copy过来后,没有删除)。
删除后问题解决。
