Action类
package com.cheer.bookshop.action;
import java.io.IOException;
import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts2.ServletActionContext;
import org.apache.struts2.convention.annotation.Action;
import org.apache.struts2.convention.annotation.Namespace;
import org.apache.struts2.convention.annotation.Result;
import com.cheer.bookshop.Model.User;
import com.cheer.bookshop.service.impl.UserServiceImpl;
import com.opensymphony.xwork2.ActionSupport;
@Namespace("/")
public class UserAction extends ActionSupport {
@Resource
private UserServiceImpl userServiceImpl;
private User user;
private String msg;
//用户登录
@Action(value = "userlogin", results = {@Result(name = "success", location = "/index.jsp"),
@Result(name = "input", location = "/jsp/user/myaccount.jsp", type = "redirect") })
public String login(){
User userdb = userServiceImpl.login(user.getUsername());
if(userdb != null){
String password = user.getPassword();
if(password.equals(userdb.getPassword())){
user=userdb;
return SUCCESS;
}else{
msg="密码错误，请重新输入！";
return INPUT;
}
}else{
msg="用户名不存在，请注册！";
return INPUT;
}
}
//用户注册
@Action(value = "userregister", results = {@Result(name = "success", location = "/jsp/user/myaccount.jsp", type = "redirect") })
public String register(){
userServiceImpl.register(user);
return SUCCESS;
}
//验证用户名是否已经被使用
@Action(value = "validateUsername")
public String validateUsername() throws IOException{
HttpServletRequest request = ServletActionContext.getRequest();
HttpServletResponse response = ServletActionContext.getResponse();
response.setContentType("text/html;charset=UTF-8");
String username = request.getParameter("username");
boolean flag = userServiceImpl.validateUsername(username);
if(flag){
response.getWriter().println("<p><font color='red'>用户名已经存在</font></p>");
}else{
response.getWriter().println("<p><font color='green'>用户名可以使用</font></p>");
}
return NONE;
}
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
public String getMsg() {
return msg;
}
public void setMsg(String msg) {
this.msg = msg;
}
}
如上，Action有配置userlogin,登陆页form表单提交路径也是一样，单就是无法调整至aciton里，eclipse也没有报错，该如何解决？
There is no Action mapped for namespace / and action name userlogin.
