struts2+spring 问题

Question

按默认配置 struts.xml放到 classpath下加载没问题 但是在将路径改变到其他目录下就报错了。

struts.xml

 <struts>
        <constant name="struts.objectFactory" value="spring" />
        <constant name="struts.convention.result.path" value="/WEB-INF/view"></constant>
        <constant name="struts.convention.exclude.packages" value="com.bill.exam.controller.*"></constant>
        <constant name="struts.devMode" value="true" />
    </struts>

web.xml

      <filter>
    <filter-name>struts</filter-name>
    <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
   <init-param>
        <param-name>config</param-name>
        <param-value>classpath:org/bill/exam/struts.xml</param-value>
    </init-param>
  </filter>

错误信息

这是什么原因呢 ？？

Answer 1

加了 我在网上找到 说在 <init-param>

        <param-name>config</param-name>

        <param-value>classpath:org/bill/exam/struts.xml</param-value>

    </init-param>这初始化参数中加一个 struts-default.xml 不管这个配置文件是否存在 加上就可以了

可能struts2加载配置文件时应该 有这样一个bug

Answer 2

struts 的 spring plugin 有个 jar 包，不知道楼主加进来没有
