struts2 简单登录校验示例

一、实验目的

理解并掌握业务控制类创建的不同方式。

理解struts.xml中action配置各属性的作用以及result配置参数作用。

二、实验内容

采用不同业务控制类定义方式实现Login原型。

深入理解struts.xml配置文件作用。

三、 实验步骤及代码

采用struts2框架实现Login原型，业务控制类实现方式：直接实现（CheckAccount、CheckAccountI）、

实现Action接口(CheckAccountII)、继承父类ActionSupport(CheckAccountIIII)。

login.jsp

  	

	  	UserName:

	    PassWord:

	    
  	
  

CheckAccount.java

package com.util.login;
public class CheckAccount {
	private String username;
	private String password;
	public String getUsername() {
		return username;
	}

	public void setUsername(String username) {
		this.username = username;
	}

	public String getPassword() {
		return password;
	}

	public void setPassword(String password) {
		this.password = password;
	}

	public String execute(){
		if(username.equals("zhangsan") && password.equals("123")){
			return "success";
		} else {
			return "error";
		}
	}
}

CheckAccountI.java (JavaBean封装)

package com.util.login;

public class CheckAccountI {
	private Account account;
	public Account getAccount() {
		return account;
	}

	public void setAccount(Account account) {
		this.account = account;
	}
	public String execute(){
		if(account.getUsername().equals("zhangsan") && account.getPassword().equals("123")){
			return "success";
		} else {
			return "error";
		}
	}
}

CheckAccountII.java (实现Action接口)

package com.util.login;
import com.opensymphony.xwork2.Action;
public class CheckAccountI implements Action {
	private Account account;
	public Account getAccount() {
		return account;
	}
	public void setAccount(Account account) {
		this.account = account;
	}

	public String execute() throws Exception {
		if(account.getUsername().equals("zhangsan") && account.getPassword().equals("123")){
			return SUCCESS;
		} else {
			return ERROR;
		}
	}
}

CheckAccountIII.java (继承ActionSupport)

package com.util.login;
import com.opensymphony.xwork2.ActionSupport;
public class CheckAccountII extends ActionSupport{
	private Account account;
			
	public Account getAccount() {
		return account;
	}
	public void setAccount(Account account) {
		this.account = account;
	}

	@Override
	public String execute() throws Exception {
		if(account.getUsername().equals("zhangsan") && account.getPassword().equals("123")){
			return "success";
		} else {
			return "error";
		}
	}
}
