## 前言 ##

今天学长向大家分享一个 java web项目:

**基于JAVA的机场航班起降与协调管理系统**

--------------------

## 一、项目设计 ##

### 1. 模块设计 ###

### 2. 实现效果 ###

地面指挥员登录页面用户名为userName，密码为password，登录按钮为submit按钮，重置按钮为button按钮。  
当点击登录时，服务器会进行用户名密码的验证，当用户名和密码为空时，显示用户名密码为空；当用户名密码错误时显示用户名密码错误。当验证正确时，跳转到index.jsp页面，运用到了数据传递的doget和dopost的方法。下面列出了doGet和doPost的主要方法，服务器端部分代码如下：

protected void doGet(HttpServletRequest request, HttpServletResponse response)
    			throws ServletException, IOException {
        
    		this.doPost(request, response);
    	}
    
    	protected void doPost(HttpServletRequest request, HttpServletResponse response)
    			throws ServletException, IOException {
        
    		String userName=request.getParameter("userName");
    		String password=request.getParameter("password");
    		request.setAttribute("userName", userName);
    		request.setAttribute("password", password);
    }

## 二、部分源码 ##

部分代码示例：

在显示航班指令信息和执行航班指令信息的操作时，都需要访问数据库或者将修改写入数据库，以指令信息的读取为例，则我们需要如下代码：
    
    public ResultSet standardList(Connection con,PageBean pageBean,Standard standard)throws Exception{
        
    		StringBuffer sb=new StringBuffer("select * from t_standard s,t_grade g where s.gradeId=g.id");
    	
    		return pstmt.executeQuery();
    	}
    	
    	public int standardCount(Connection con,Standard standard)throws Exception{
        
    		StringBuffer sb=new StringBuffer("select count(*) as total from t_standard s,t_grade g where s.gradeId=g.id");
    
    		PreparedStatement pstmt=con.prepareStatement(sb.toString());
    		ResultSet rs=pstmt.executeQuery();
    	
    	}
    
    
    在删除航班信息时，如果航班已经发出指令，则不能删除航班，这就涉及到数据库的关联操作：
    
    public boolean getStandardByGradeId(Connection con,String gradeId)throws Exception{
        
    		String sql="select * from t_standard where gradeId=?";
    		PreparedStatement pstmt=con.prepareStatement(sql);
    		pstmt.setString(1, gradeId);
    		ResultSet rs=pstmt.executeQuery();
    		if(rs.next()){
        
    			return true;
    		}else{
        
    			return false;
    		}
    	}
