Question

我开始在Spring应用程序中使用Struts2 Rest插件。让我们从 struts.xml 开始：

<struts>
    <constant name="struts.devMode" value="true" />
    <constant name="struts.custom.i18n.resources" value="lang/messages" />
    <constant name="struts.ognl.allowStaticMethodAccess" value="true" />
    <constant name="struts.mapper.class" value="rest" />

    <package name="default">
        <action name="document" class="DocumentRestaction" />
    </package>
</struts>

然后在Spring中，我正在执行以下操作（以查看是否注入了String）：

<bean name="DocumentRestaction" class="be.example.actions.DocumentRestaction">
    <property name="injected" value="Oh Hai" />
</bean>

我对网址POST发出了/documents个请求，并以create()方式结束，太棒了！在调试中，我的injected变量被注入。但是当我继续调试时，我得到以下异常：

4129 [http-8080-2] ERROR org.apache.struts2.rest.RestActionInvocation - Exception processing the result.

但是这个课程已被发现..（我最终在create），为什么这么说？最重要的是，我做错了什么？

我正在使用Spring v3.0.5，struts2-rest-plugin v2.3.1，struts2-core v2.3.1和struts2-spring-plugin 2.3.1

如果有人正在寻找解决方案，this文章可能有帮助。

虽然在您的applicationContext.xml中给出了示例代码中的遗漏，但请确保将“id”和“class”定义为控制器的完全限定类名：

   <bean id="com.mersoft.web.controller.TestController" class="com.mersoft.web.controller.TestController">
      <constructor-arg ref="testManager" />
   </bean>

希望有所帮助。哦，并且要清楚，您不必像先前评论中所建议的那样删除约定插件。

在Spring中使用Struts2-Rest-Plugin
