struts2的转发页面错误(404)
测试struts2中的Action是如何通过ActionContext访问Servlet API的,实例是模仿登录业务逻辑,分别把登录用户名保存在application和session中,然后从jsp页面中读取信息
可是我页面跳转的时候报404找不到页面的错误,仔细检查了struts.xml,好像也没有什么错误啊!
登录业务逻辑:LoginAction.java
package com;
import java.util.Map;
import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.ActionContext;
@SuppressWarnings("serial")
public class LoginAction extends ActionSupport{
private String name;
private String pwd;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPwd() {
return pwd;
}
public void setPwd(String pwd) {
this.pwd = pwd;
}
@SuppressWarnings("unchecked")
public String checkLogin(){
ActionContext ac = ActionContext.getContext();
@SuppressWarnings({ "unused", "rawtypes" })
Map app = ac.getApplication();
ac.getSession().put("login", this.name);
ac.getApplication().put("login", this.name);
return SUCCESS;
}
}
