struts2 零配置 注解方式

Question

今天想尝试下Struts2的注解方式在web.xml里修改了原来的Filter 
<filter>
  <filter-name>struts2</filter-name>
  <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
  
  <init-param>
<param-name>actionPackages</param-name>
<param-value>manning.chapterTwo</param-value>
</init-param>
</filter>然后在包manning.chapterTwo下面添加一个Action,代码如下：
package manning.chapterTwo;import org.apache.struts2.convention.annotation.Result;
import com.opensymphony.xwork2.ActionSupport;@Result(name="success",location="login.jsp")public class AnnotationAction extends ActionSupport {
 
/**
 * 
 */
private static final long serialVersionUID = 2296720831644414741L;
public String execute()
{

return "success";
}}启动，访问http://127.0.0.1:8888/Struts/annotationAction.action                 Struts是工程名提示说找不到action
是我少配什么东西了么？

Answer 1

Struts 版本是最新的2.3.3  

Answer 2

是否使用了spring ？启用注解需要在配置文件中声明这两个东西
     <!-- 用注解方式注入bean -->
    <context:annotation-config/>
    
    <!-- 扫描包路径 -->   
    <context:component-scan base-package="com"/>

Answer 3

没用Spring，也许哟啊加这些么？

@ParentPackage(value="default")//命名空间默认default
@Action//表明是一个Action

})public class SubjectAction extends BaseAction{

Answer 5

web.xml
<filter>
  <filter-name>struts2</filter-name>
  <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
  
  <init-param>
<param-name>actionPackages</param-name>
<param-value>manning.chapterTwo</param-value>
</init-param>
</filter><filter-mapping>
  <filter-name>struts2</filter-name>
   <url-pattern>/*</url-pattern>
</filter-mapping>
试了半天都没效果....
package manning.chapterTwo;import org.apache.struts2.convention.annotation.Action;
import org.apache.struts2.convention.annotation.ParentPackage;
import org.apache.struts2.convention.annotation.Result;
import com.opensymphony.xwork2.ActionSupport;@ParentPackage(value="manning.chapterTwo")
@Action
@Result(name="success",location="login.jsp")public class AnnotationAction extends ActionSupport {
 
/**
 * 
 */
private static final long serialVersionUID = 2296720831644414741L;
public String execute()
{

return "success";
}}struts.properties
struts.devMode=false
struts.enable.DynamicMethodInvocation=true
struts.i18n.reload=true
struts.ui.theme=simplestruts.locale=zh_CN
struts.i18n.encoding=GBKstruts.serve.static.browserCache=false
struts.url.includeParams=none

Answer 6

访问地址是：http://127.0.0.1:8888/Struts/annotationAction.action

Answer 7

我还是有配置文件的，只是少了action的节点<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC 
"-//Apache Software Foundation//DTD Struts Configuration 2.1//EN"
"http://struts.apache.org/dtds/struts-2.1.dtd">

<struts>


<constant name="struts.devMode" value="true" />
<constant name="struts.i18n.encoding" value="UTF-8" />
<constant name="struts.custom.i18n.resources" value="messages" />
<!-- 配置默认的Action -->
 
<package name="default" namespace="/" extends="struts-default">

<interceptors>
<!-- 定义权限验证拦截器 -->
<interceptor name="AuthInterceptor" class="cn.jbit.votingsystem.interceptor.AuthInterceptor"/>



<!-- 自定义连接器栈-->
<interceptor-stack name="myStack">
<interceptor-ref name="defaultStack"/>
<interceptor-ref name="AuthInterceptor"/>

</interceptor-stack>
</interceptors>

<!-- 使用拦截器栈 -->
   <default-interceptor-ref name="myStack"/>
   
   <global-results>
<result name="error" >/WEB-INF/page/error.jsp</result>
<result name="login">/WEB-INF/page/login.jsp</result>
</global-results>





</package>

</struts>
然后Acton里面才是这样写的
/**
 * @author haigejiang
 *
 */
@ParentPackage(value="default")//命名空间默认default
@Action//表明是一个Action
@Results(value={
@Result(name="addsuccess",location="subject!addsuccess.action",type="redirectAction"),
@Result(name="success",location="/WEB-INF/page/add_success.jsp"),
@Result(name="index",location="/WEB-INF/page/index.jsp"),
@Result(name="toadd",location="/WEB-INF/page/add.jsp"),
@Result(name="tovote",location="/WEB-INF/page/vote.jsp")
})public class SubjectAction extends BaseAction{

Answer 8

我回复自己怎么没看见呢？我估计还是得配置struts.xml文件

Answer 9

http://127.0.0.1:8888/Struts/annotationAction.action访问地址应该是：http://127.0.0.1:8888/Struts/annotation.action

Answer 10

你的ACTION访问路径错了，应该是
http://127.0.0.1:8888/Struts/annotation.action约定的规则是：如果是已Action结尾要去掉Action，以大小写为单词分隔，以“-”符号分割。
我的项目里有个ACTION的命名是WsThreadInfoAction，访问它的链接就是ws-thread-info.action

Answer 11

刚才又试了一下，放在默认的package下面就没事
新建一个package就不行了struts.xml文件如下
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
<struts> <package name="armeng" namespace="/" extends="struts-default">

  <action name="submit"   class="action.MoreSubmitAction">
<result name="save">/result.jsp</result>
<result name="print">/result.jsp</result>
</action>
<action name="login">
<result>/login.jsp</result>
</action> <action name="userLogin" class="action.LoginAction">
                <result name="success" type="freeer">
                    /WEB-INF/templates/user.ftl
                </result>
                <result name="jspsuccess" >
                    /loginsuccess.jsp
                </result>
        </action>
        

</package>

<package name="haha" namespace="/zero" extends="struts-default">
<action name="sum" class="test.FirstAction">
<result name="positive">/positive.jsp</result>
<result name="negative">/negative.jsp</result>
</action>

</package>

</struts>
test.FirstAction是用来验证package生效的Action,可以运行web.xml<filter>
  <filter-name>struts2</filter-name>
  <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
  
  <init-param>
<param-name>actionPackages</param-name>
<param-value>haha</param-value>
</init-param>
</filter>Action类
package test;import org.apache.struts2.convention.annotation.Action;
import org.apache.struts2.convention.annotation.ParentPackage;
import org.apache.struts2.convention.annotation.Result;
import com.opensymphony.xwork2.ActionSupport;@ParentPackage(value="haha")
@Result(name="success",location="/login.jsp")public class AnnotationAction extends ActionSupport {
 
/**
 * 
 */
private static final long serialVersionUID = 2296720831644414741L;
public String execute()
{

return "success";
}}访问链接
http://127.0.0.1:8888/Struts/annotation.action

Answer 12

现在已经正常了。配置如下：AnnotationAction在test这个包下面
web.xml<filter>
  <filter-name>struts2</filter-name>
  <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
  
  <init-param>
<param-name>actionPackages</param-name>
<param-value>test</param-value>
</init-param>
</filter><filter-mapping>
  <filter-name>struts2</filter-name>
   <url-pattern>/*</url-pattern>
</filter-mapping>struts.xml
<constant name="struts.convention.package.locators" value="test,action" />
