使用stream类型的result实现ajax

package com.lee.action;

import java.io.ByteArrayInputStream;
import java.io.InputStream;

import com.opensymphony.xwork2.ActionSupport;

public class AJAXLoginAction extends ActionSupport {

    private static final long serialVersionUID = 1L;

    private String username;

    private String password;

    private InputStream inputStream;

    public String execute() throws Exception {

        inputStream = "lizhe".equals(username) && "lz123456".equals(password) ? new ByteArrayInputStream(
            "成功 success!".getBytes("GBK")) : new ByteArrayInputStream("失败 fail!".getBytes("GBK"));
            
            System.out.println(inputStream);

        return SUCCESS;
    }

    /**
     * @return the username
     */
    public String getUsername() {
        return username;
    }

    /**
     * @param username the username to set
     */
    public void setUsername(String username) {
        this.username = username;
    }

    /**
     * @return the password
     */
    public String getPassword() {
        return password;
    }

    /**
     * @param password the password to set
     */
    public void setPassword(String password) {
        this.password = password;
    }

    /**
     * @return the inputStream
     */
    public InputStream getInputStream() {
        return inputStream;
    }

    /**
     * @param inputStream the inputStream to set
     */
    public void setInputStream(InputStream inputStream) {
        this.inputStream = inputStream;
    }

}
