这是我的StrutsConfig.xml：

<?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">

    <constant name="struts.devMode" value="true" />
    <constant name="struts.custom.i18n.resources" value="myapp" />

    <package name="user" extends="struts-default" namespace="/">
        <result-types>
            <result-type name="tiles" class="org.apache.struts2.views.tiles.TilesResult" />
       </result-types>
        <action name="user" class="user" method="execute">
            <result name="user" type="tiles">mainTemplate</result>
        </action>
        <action name="*menu" class="user" method="{1}">
            <result name="user" type="tiles">mainTemplate</result>
            <result name="madhuri" type="tiles">madhuri</result>
            <result name="alia" type="tiles">alia</result>
            <result name="addUser" type="tiles">mainTemplate</result>
            <result name="deleteUser" type="tiles">mainTemplate</result>

        </action>
    </package>
 </struts>

这是我的USerAction.jsp：

public class UserAction extends ActionSupport implements ModelDriven<UserBean>{

    private static final long serialVersionUID = 1L;

    @Autowired
    private UserBean userBean;
    @Autowired
    private UserService userService;
    private List<UserBean> users;

    public String execute() {
        users = CommonUtility.createUserBeanList(userService.getUserList());
        return "user";
    }

    public String addUser(){
        userService.saveUser(CommonUtility.createModel(userBean));
        users = CommonUtility.createUserBeanList(userService.getUserList());
        return "addUser";
    }

    public String deleteUser(){
        userService.deleteUser(CommonUtility.createModel(userBean));
        users = CommonUtility.createUserBeanList(userService.getUserList());
        return "deleteUser";
    }

    public String listUser(){
        users = CommonUtility.createUserBeanList(userService.getUserList());
        return "users";
    }

    @Override
    public UserBean getModel() {
        return userBean;
    }
    public String alia() { 
        return "alia";
    }
    public String madhuri() { 
        return "madhuri"; 
    }
    public String user() { 
        return "user"; 
    }

    public List<UserBean> getUsers() {
        return users;
    }

    public void setUsers(List<UserBean> users) {
        this.users = users;
    }

}


public String deleteUser(){
        userService.deleteUser(CommonUtility.createModel(userBean));
        users = CommonUtility.createUserBeanList(userService.getUserList());
        return "deleteUser";
    }

功能不起作用我在哪里做错了请帮助我，我认为有一些小错误，所以我无法找到错误。

表单提交的动作名称为addUsermenu。

在您的struts.xml,中，您有一个操作标记，指向所有与菜单匹配的方法。所以你的addUsermenu会找到相应的方法。即addUser（）。

但是在删除的情况下，您必须将操作名称更改为deleteUsermenu才能找到函数deleteUser()

解将删除链接更改为此

<a href="delete">Delete</a>

到这个

<a href="<s:url action='deleteUsermenu'/>">Delete</a>

如何在Struts2中激活
