因为项目需要Android直连服务端mysql数据库，特写下笔记

1.连接数据库驱动依赖：compile'mysql:mysql-connector-java:5.1.18'

2.代码如下

Connection connection =null;

//数据实体类

SouSuoCiData data;

//实体类list

gjclist=newArrayList();

try{

//加载驱动

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

//数据库ip地址/端口/数据库名

String url ="jdbc:mysql://192.168.0.103:3306/test";

                                                                                        //root是我这个数据库的账号，123456是密码

connection = (Connection) DriverManager.getConnection(url,"root","123456");

Statement statement = (Statement) connection.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);

                                                                                    //写查询语句

ResultSet resultSet = statement.executeQuery("select * from gjcbg");

//解析查询的数据

while(resultSet.next()) {

data=newSouSuoCiData();

//Log.i("TAG", "rs="+resultSet.toString());

data.setTime(resultSet.getString("sj"));

data.setJh(resultSet.getString("jh"));

data.setDy(resultSet.getString("dy"));

data.setGjc(resultSet.getString("gjc"));

data.setSsc(resultSet.getString("ssc"));

data.setZx(resultSet.getInt("zx"));

data.setDj(resultSet.getInt("dj"));

// Log.i("TAG", "data="+data.toString());

ssclist.add(data);

}

}catch(ClassNotFoundException | SQLException | InstantiationException | IllegalAccessException e) {

e.printStackTrace();

}finally{

try{

if(connection !=null) {

connection.close();

}

}catch(SQLException e) {

e.printStackTrace();

}

}
