與jtds錯誤的Sql服務器的Java連接

我使用此代碼與Sql服務器建立連接，並且當我使用Class.forName（驅動程序）時它出現錯誤它正確連接，但我更喜歡使用DataSourse。與jtds錯誤的Sql服務器的Java連接

static final BasicDataSource dataSource = new BasicDataSource(); 


static { 
    dataSource.setDriverClassName("net.sourceforge.jtds.jdbc.Driver"); 
    dataSource.setUrl("jdbc:jtds:sqlserver://Mypc/Mydb;instance=SQLEXPRESS;"); 
    dataSource.setUsername(""); 
    dataSource.setPassword(""); 


} 

public static void main(String[] args){ 
    try{ 
dataSource.getConnection(); 
} 
    catch (SQLException ex){ 
     System.out.println(ex); 
    }} 


public static Connection getConnection() throws SQLException { 
    return dataSource.getConnection(); 
}

和我得到這個

Exception in thread "main" java.lang.AbstractMethodError

at org.apache.commons.dbcp2.DelegatingConnection.isValid(DelegatingConnection.java:918)

嘗試設置驗證查詢：'dataSource.setValidationQuery（「SELECT 1」）' – Berger

[Tomcat 8上的jTDS JDBC驅動程序的AbstractMethodError的可能重複]（http://stackoverflow.com/questions/41231750/abstractmethoderror-with-jtds-jdbc-driver-on-tomcat-8） – Berger

您必須添加validationQuery="select 1"您dataSource

dataSource.setValidationQuery("select 1");
