第一篇文章
大家好，我正在尝试运行由另一个开发人员开发的Java Web项目。目前，我正在尝试运行该项目，但该项目未连接到数据库。在登录屏幕中，我正在从数据库中检索一些数据并将它们显示在下拉列表中，但是当用户输入名称和密码时，它不会显示任何错误消息或重定向到下一页，也不会在控制台中显示任何错误。 这是我的连接代码：
public final class MySqlConnect {
Logger logger = Logger.getLogger(MySqlConnect.class.getName());
public Connection conn;
private Statement statement;
public static MySqlConnect db;
private MySqlConnect() {
String url= "jdbc:mysql://localhost:3306/";
String dbName = "anish";
String driver = "com.mysql.jdbc.Driver";
String userName = "root";
String password = "root";
try {
Class.forName(driver).newInstance();
this.conn = (Connection)DriverManager.getConnection(url+dbName,userName,password);
}
catch (Exception sqle) {
logger.info(sqle.getMessage());
}
}
public static synchronized MySqlConnect getDbCon() {
if ( db == null ) {
db = new MySqlConnect();
}
return db;
}
public ResultSet query(String query) throws SQLException{
statement = db.conn.createStatement();
System.out.println(query);
ResultSet res = statement.executeQuery(query);
return res;
}
public int insert(String insertQuery) throws SQLException {
statement = db.conn.createStatement();
System.out.println(insertQuery);
int result = statement.executeUpdate(insertQuery);
return result;
}
public int insertAndgeneratedRowId(String insertQuery) throws SQLException {
statement = db.conn.createStatement();
System.out.println(insertQuery);
int result = statement.executeUpdate(insertQuery,Statement.RETURN_GENERATED_KEYS);
int auto_id = 0;
if(result > 0) {
ResultSet rs = statement.getGeneratedKeys();
rs.next();
auto_id = rs.getInt(1);
}
return auto_id;
}
}
似乎连接正常，因为我正在获取下拉列表的数据，但是 当我查询某些东西时，它什么也没显示。 例如用户输入名称和密码后，应重定向到下一页。
