Struts2的零配置方法总结

以下内容参考网上的资料

间接实现零配置
   struts.xml

<action name="*/*" method="{2}" class="workbench.web.actions.{1}Action">   
<result name="custom">/view/{1}/${target}.jsp</result>
</action>

编写一个基础的Action

public abstract class BaseAction {       
protected final String CUSTOM = "custom";
private String target;
protected final Log logger = LogFactory.getLog(getClass());       public String getTarget() {
return target;}
public void setTarget(String target) {
this.target = target;}              
protected String render(String _target){
setTarget(_target);
return CUSTOM;}
} 

public class UserAction extends BaseAction{       private User user;
private UserService userService;
public void setUserService(UserService userService) {
this.userService = userService; }              
public User getUser() {
return user;}       
public void setUser(User user) {
this.user = user; }       
public String test(){
user = userService.get(1l);
return render("test"); }
} 

访问:http://localhost:8080/workbench/User/test

真正的夫配置，它是基于包的路径的
原文：http://www.iteye.com/post/390374
web.xml：

<filter>   
	<filter-name>struts2</filter-name>   
	<filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>   
	<init-param>   
		<param-name>actionPackages</param-name>   
		<param-value>demo.actions1,demo.actions2</param-value>   
	</init-param>   
</filter>

Struts2扫描到Action后，从actionPackages指定的包开始，子包名会成为这个Action的namespace，而Action的name则由这个Action的类名决定。将类名首字母小写，如果类名以Action结尾，则去掉"Action"后缀，形成的名字就是这个Action的名字。在如上所述的示例中，actionPackages指定为demo.actions1,demo.actions2，那么你可以这样访问demo.actions1.app.person.ListPeopleAction：
http://localhost:8080/app/person/listPeople
Struts2是通过"Result"和"Results"两个类级别的annotations来指定Results的。
作为示例，我们在webapp目录下建两个html文件：success.html和error.html，随便写点什么内容都可以。现在假设我们访问/app/person/listPeople时，或Action返回success就转到success.html页面，若是error就转到error.html页面，这只需要在ListPeopleAction类上加上一段注解就可以了：

@Results({   
    @Result(name="success", type=NullResult.class, value = "/success.html", params = {}),   
    @Result(name="error", type=NullResult.class, value = "/error.html", params = {})   
})  
 
public class ListPeopleAction {   
    public String execute() {   
        return "success";   
    }   
}
