Android连接MySQL数据库
public static boolean login(String username, String password) {
boolean b = false;
try {
Connection con= DriverManager.getConnection(URL,USER,PASSWORD);
Statement stam = con.createStatement();
// con = this.getConn();
con.setAutoCommit(false);
//由当前数据库连接生成一个数据库操作对象
stam = (Statement) con.createStatement();
String sql = String.format(
"SELECT * FROM user where username='%s' and password='%s'",
username, password);
//查询的结果存到了resultset中
ResultSet rs = stam.executeQuery(sql);
con.commit();
b = rs.next();
} catch (SQLException e) {
e.printStackTrace();
}
return b;
}b的返回值总是false,求大神帮帮忙!在此谢过了!!!
