1.mysql設定

對於海之舟1.0A作業系統，mysql、java、tomcat已預裝，在/etc/rc.local中設定開機啟動即可。

su root

nano /etc/mysql/mariadb.conf.d/50-server.cnf

#bind-address = 127.0.0.1 //註釋這行,關閉ip限制.

mysql -v //進入資料庫

>use mysql;

>CREATE DATABASE db1;

>SHOW DATABASES;

>grant all on *.* to zs1@'%' identified by '1234';

>show grants for zs@'%';

>use db1;

> CREATE TABLE t1(bid int(20) not null auto_increment primary key, id int(100),xm varchar(20),zh varchar(100),uploadTime varchar(100));

>SHOW TABLES;

> DESCRIBE t2; //檢視錶t2的結構

> insert into t1(id,xm,zh) values (20,"zhangs","myzh");

2.jsp

su zs

cd /home/zs/apache-tomcat-8.5.35/webapps/ROOT

nano m1.jsp //已預置的範例程式碼

<%@ page contentType="text/html;charset=UTF-8"%>

<%@ page import="java.sql.*"%>

<html>

<head>

response.setContentType("text/html;charset=UTF-8");

request.setCharacterEncoding("UTF-8");

</head>

<body>

<%

Class.forName("com.mysql.cj.jdbc.Driver").newInstance();

Connection conn=DriverManager.getConnection("jdbc:mysql://localhost:3306/db1", "zs1", "1234");

Statement stmt=conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,

ResultSet.CONCUR_UPDATABLE);

String id=request.getParameter("id");

String sql="select * from t1 order by bid";

ResultSet rs=stmt.executeQuery(sql);

out.print("<br>sql:"+sql);

out.print("<br>bid-----id-----xm-----zh");

while(rs.next())

{

out.print("<br>  "+rs.getInt(1));

out.print("    "+rs.getString(2));

out.print("    "+rs.getString(3));

out.print("    "+rs.getString(4));

}

//c=Integer.parseInt(ss);

rs.close();

stmt.close();

conn.close();

%>

</body>

在流覽器中開啟192.168.1.125:8080/m1.jsp即可
