錯誤在Java中

Question

連接DB2數據庫，我不能對DB2數據庫在Springsoruce連接，並提示以下錯誤：，

2017/05/19 10:10:31.588 [ERROR] An unexpected error occurred when attempting to establish connection to database. The error was: com.ibm.db2.jcc.c.fc.a(fc.java:371) 371

以下外部JAR的都包括在該計劃，但仍然得到了錯誤，而建立連接到數據庫。

db2jcc.jar 
db2jcc_license_cisuz.jar 
db2java.jar 

下面是我使用建立數據庫連接和數據庫的細節是從命名設置另一個類文件中導出的代碼，

import java.io.BufferedReader; 
import java.sql.Connection; 
import java.sql.DriverManager; 

public class DBConnection 
{ 
    logWriter LogWriter = new logWriter(); 

    public Connection getDBConnection = null; 

    public Connection getDBConnection() { 
    Connection DBConnection = null; 
    try { 
     System.out.println("Connecting to OF database " + Settings.DBName + "."); 
     String DBURL = "jdbc:db2://" + Settings.DBServer + ":" + Settings.DBPort + "/" + Settings.DBName + ":currentSchema=" + Settings.DBSchema + ";"; 
     System.out.println(DBURL);  
     DBConnection = DriverManager.getConnection(DBURL, "username", "password"); 
     LogWriter.writeEvent(3, "Database connection successfully established to database " + Settings.DBName + " using user " + Settings.DBUser + "."); 
     return DBConnection; 
    } 
    catch (Exception e) 
    {  
     LogWriter.writeEvent(1,"An unexpected error occurred when attempting to establish connection to database " + Settings.DBName + ". The error was: " + LogWriter.getStackTraceString(e)+ "\r\n"); 
    } 
    return DBConnection; 
    } 
}

很難找到沒有任何代碼，但也許這可以幫助： https://www.ibm.com/support/knowledgecenter/en/SS3JRN_7.2.0/com.ibm.itcamsoa.doc/kd4trmst34.htm
