如何配置struts约定插件与struts弹簧插件的Action类映射与注释

Question

我正在尝试用strut 2应用程序配置spring插件，该应用程序已经在使用约定插件运行，所以我使用了注释。我使用ExtJs提交表单，在我引入spring插件之前，它最初运行良好，现在ajax请求无法定位操作，并且在firebug中没有显示任何响应。

行动类

@Namespace("/units")
@Result(
    type = "stream",
    params = {
        "inputName", "stream"
    }
)
public class PropertyTypeAction extends BaseAction implements ActionImpl{
    @PersistenceUnit
    private EntityManagerFactory emf;
    @Action(value="add")
    public String add() {
        .......
    }
}

Ajax请求firebug报告，XML选项卡

我的问题是如何配置struts-spring插件来使用带有注释的struts约定插件。

Answer 1

您正在导入struts2弹簧插件和struts2 CDI插件。

不要。

只选择上面的一个插件，然后正确配置：

• 要使用CDI插件，只需使用Maven导入JAR，并开始使用（右）@Inject注释注释要注入的对象。

• 要使用Spring插件，请导入JAR，在web.xml中添加ContextLoaderListener（您已经设置好了），并指定要在struts.xml中使用Spring作为objectFactory，常量为：

  <constant name="struts.objectFactory" value="spring" /> 
  

IMHO如果您使用Java EE>=6，CDI插件是更好的选择。
