这是我使用maven多模块去改造普通web项目是遇到的,开始发现单个无依赖区启动maven的web模块正常,加上就会报spring初始化失败,以及各种bean无法被注入

偶然情况下发现我在maven的web模块下发现加入了dubbo的jar包就会报错,上网了解到dubbo自身继承了spring2.x.jar,再看我的web模块缺失使用的spring3.x,

猜想会不会是因为spring2.x与spring3.x冲突呢，然后采取

<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>dubbo</artifactId>
    <version>2.5.3</version>
    <exclusions>
       <exclusion>
       <groupId>org.springframework</groupId>
       <artifactId>spring</artifactId>
    </exclusion>
    <exclusion>
          <artifactId>netty</artifactId>
          <groupId>org.jboss.netty</groupId>
       </exclusion>
    </exclusions>
</dependency>

再次运行,正常,添加依赖后正常
