JDBC + postgres 连接问题

Question

I've a problem when i'm connecting to a postgresql database with jdbc. I've install postgresql 9.1 from a package download on the pgAdmin3 site (i needed gui). I'm connecting to db whith pgAdmin with no problems, but when i try to connect from java code, i've the sequent error:

org.postggresql.util.PSQLException: FATAL: password authentication failed for user postgres

the code that throws the exception is

public class ConnectionManager {
   private ConnectionManager(){};
   private static boolean driverLoad = false;
   private static final String pgDriver="org.postgresql.Driver";
   private static final String pgUrl="jdbc:postgresql:coffeeDB";
   private static final String usr="postgres";
   private static final String psw="password";

   public static Connection getConnection() throws ClassNotFoundException, SQLException {
       if(!driverLoad) {
           Class.forName(pgDriver);
           driverLoad=true;
       }
       return DriverManager.getConnection(pgUrl, usr, psw);
   }
}

Answer 1

I've solved.Just add the default port on the URL of postgresql

Answer 2

I was getting this in Play 2.2. A slightly different flavor

[error]c.j.b.h.AbstractConnectionHook - Failed to obtain initial connection Sleeping for 0ms and trying again. Attempts left: 0. Exception: null.Message:FATAL: password authentication failed for user "root"

Issue was quotes around the url in application.conf. If there are special characters, quotes are needed

Fails

db.default.url=jdbc:postgresql://myMachine:5432/mydb

Works

db.default.url="jdbc:postgresql://myMachine:5432/mydb"

Same goes for password

Fails

Passw)rd#!

Works

"Passw)rd#!"
