我正在使用以下代码来初始化数据库连接:
public Connection getConnection() {
try {
if (null == connection) {
String driverName = "com.mysql.jdbc.Driver"; // MySQL MM JDBC driver
Class.forName(driverName);
// Create a connection to the database
String serverName = "localhost";
String database = "database";
String url = "jdbc:mysql://" + serverName + "/" + mydatabase; // a JDBC url
String username = "username";
String password = "password";
connection = DriverManager.getConnection(url, username, password);
}
return connection;
} catch (ClassNotFoundException cnfe) {
cnfe.printStackTrace();
} catch (SQLException sqle) {
sqle.printStackTrace();
}
throw new NullPointerException("Cannot establish database connection...");
}
而且我知道这样做是不好的做法,我也FindBugs
违反了代码,并遇到了安全问题,如下所示:
This code creates a database connect using a hardcoded, constant password. Anyone with access to either the source code or the compiled code can easily learn the password.
在没有这种安全漏洞的情况下初始化数据库连接的最佳方法是什么?
