3. selvet功能实现类

package useDao;

import java.io.*;
import java.sql.*;

import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

/**
 * Servlet implementation class Servletword
 */
@WebServlet("/Servletword")
public class Servletword extends HttpServlet {
	private static final long serialVersionUID = 1L;
       
    /**
     * @see HttpServlet#HttpServlet()
     */
    public Servletword() {
        super();
        // TODO Auto-generated constructor stub
    }

	/**
	 * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
	 */
	protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		// TODO Auto-generated method stub
		response.setContentType("application/msword;charset=UTF-8");                //定义文件输出样式
        UseDao connection = new UseDao(); 
        request.setCharacterEncoding("UTF-8");
	     String profession = request.getParameter("tb_name");           //获取查询条件
	     PrintWriter out = response.getWriter();
	     try {
	    	String sql= "select distinct * from tb_book where tb_name='"+profession+"'";
	    	 ResultSet rs = connection.selectStatic(sql); 
	        while(rs.next()) {
	                 out.print(rs.getInt("tb_id"));
	              out.print("  ");

	                 out.print(rs.getString("tb_name"));

	                 out.print("  ");

	                 out.print(rs.getDouble("tb_price"));

	                 out.print("  ");

	                 out.print(rs.getInt("tb_bookCount"));
	                 out.println("   ");
	                 out.print(rs.getString("tb_author"));
	                 out.println("   ");
	        }
	      } catch (Exception e) {
	    	  System.out.println(e);
	      connection.closeConnection();
	      }

	}

	/**
	 * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
	 */
	protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		// TODO Auto-generated method stub
		doGet(request, response);
	}

}

web.xml配置

 <servlet>
    <servlet-name>UseDao</servlet-name>
    <servlet-class>useDao.UseDao</servlet-class>
  </servlet>
  <servlet-mapping>
    <servlet-name>UseDao</servlet-name>
    <url-pattern>/useDao</url-pattern>
  </servlet-mapping>

补充：UseDao.java封装了数据库连接操作、查询、更新、关闭操作，代码如下：

package useDao;

import java.sql.*;

public class UseDao {

	String url="jdbc:mysql://localhost:3306/text";
	String user="root";
	String passward="yj5211";
	private Connection con=null;
	private Statement stm=null;
	private ResultSet res=null;
	public UseDao() {
		try {
			Class.forName("com.mysql.jdbc.Driver");
		}catch(Exception e) {
			System.out.println("数据库加载失败");
		}
	}
	public boolean Connection() {//数据库连接
		try {
			con=DriverManager.getConnection(url, user, passward);
		}catch(Exception e) {
			System.out.println(e.getMessage());
		}
		
		return true;
		
	}
public ResultSet selectStatic(String sql) {//数据库查询
	
	if(con==null) {
		Connection();
	}
	try {
		stm=con.createStatement();
		res=stm.executeQuery(sql);
	}catch(Exception e){
		System.out.println(e.getMessage());
		closeConnection();//关闭数据库连接

	}

	return res;
	
}
public boolean excuteUpdate(String sql) {//更新数据库
	if(con==null) {
		Connection();
	}
	try {
	stm=con.createStatement();
	int iCount=stm.executeUpdate(sql);
	System.out.println("影响的行数" + iCount);
	}catch(Exception e) {
		System.out.println(e.getMessage());
		closeConnection();
	return false;
	}
return true;
}
public void closeConnection() {//关闭数据库连接
	try {
		System.out.println("数据库关闭");
		res.close();
		stm.close();
		con.close();
	}catch(Exception e) {
		System.out.println(e.getMessage());
		System.out.println("数据库关闭失败");
	}
}
}
