第一次写文档，看的人轻喷。做一个简单记录
话不多说，下面直接上代码。
public static void main(String[] args) {
Connection conn = null;
String sql;
// String url = "jdbc:MysqL://localhost:3306/test?" +
// "user=root&password=root&useUnicode=true&characterEncoding=utf8&useSSL=false&serverTimezone=GMT";
String url = "jdbc:MysqL://localhost:3306/test?useUnicode=true&characterEncoding=utf8&useSSL=false&serverTimezone=GMT";
String user = "root";
String password = "root";
try {
Class.forName("com.MysqL.jdbc.Driver");
log.info("成功加载MysqL驱动程序");
conn = DriverManager.getConnection(url, user, password);
Statement stmt = conn.createStatement();
sql = "create table student(No char(30), name varchar(30), primary key(No))";
int result = stmt.executeUpdate(sql);
if (result != -1) {
log.info("创建数据表成功");
sql = "insert into student(no, name) values ('201901', 'sui123')";
result = stmt.executeUpdate(sql);
sql = "insert into student(no, name) values ('201902', 'ya123')";
result = stmt.executeUpdate(sql);
sql = "select * from student";
ResultSet rs = stmt.executeQuery(sql);
while (rs.next()) {
log.info(rs.getString(1) + "\t" + rs.getString(2));
}
}
} catch (ClassNotFoundException e) {
log.error("没有找到驱动类");
throw new RuntimeException("没有找到加载类");
} catch (sqlException e) {
log.error("sql不正确", e.getMessage(), e);
throw new RuntimeException("sql不正确");
} finally {
try {
conn.close();
} catch (sqlException e) {
log.error("关闭连接失败");
throw new RuntimeException("关闭连接失败");
}
}
}
这样
