问题描述

Given below is the stack trace and I have been stuck with this problem for long time now, from the trace i could just make out that there was some problem in properly wiring up spring bean with struts for dependency injection using maven as the build tool.下面给出的是堆栈跟踪，我已经被这个问题困扰了很长时间，从跟踪中我可以看出，在使用 maven 作为构建工具时，在正确连接 spring bean 时存在一些问题，用于依赖注入。 Here baseAction if the name of the ACTION class.这里baseAction的名字如果是ACTION class。

Ok, I think all of that log is fluff except for this line:好的，我认为所有日志都是绒毛，除了这一行：

2011-07-09 21:28:52,768 DEBUG [DefaultListableBeanFactory.java:385] : No bean named 'com.app.action.BaseAction'
found in org.springframework.beans.factory.support.DefaultListableBeanFactory@169df00: defining beans [userService];
root of factory hierarchy

When spring says it cannot find a bean with that name, I believe it is telling you that it has not been informed of such a bean.当 spring 说找不到具有该名称的 bean 时，我相信它是在告诉您它还没有被告知这样的 bean。

Check in the spring context.xml (perhaps WEB-INF/spring/web-application-context.xml ) file and add a签入 spring context.xml （可能是WEB-INF/spring/web-application-context.xml ）文件

<bean id="com.app.action.BaseAction" class="com.app.action.BaseAction" />

declaration for your bean.为您的 bean 声明。
