HikariCP im Spring Boot mit JTDS konfigurieren

Question

Ich möchte einen Verbindungspool zu meiner bestehenden Webanwendung hinzufügen, der mit Spring Boot 1.5.1 erstellt wurde.

Die Datenquelle-Konfiguration wird in application.properties wie folgt hergestellt:

spring.datasource.url=jdbc:jtds:sqlserver://localhost:1433;databaseName=MyDatabase;instance=SQLServer2014; 
spring.datasource.username=myuser 
spring.datasource.password=passwd 
spring.datasource.driver-class-name=net.sourceforge.jtds.jdbc.Driver 
spring.jpa.hibernate.ddl-auto=update 

Ich brauche keine weitere Konfiguration zu machen, damit genug ist.

Es ist nicht klar genug in der offiziellen docs, obwohl Parameter angezeigt werden, noch in der Spring Boot docs.

Also, ich habe nach Lösungen gesucht (this one, this one too ...).

Ich habe mehrere Versuche gemacht, aber jedes Mal, wenn ich die App starte, werden Ausnahmen bezüglich HikariCP ausgelöst.

Wenn spring.datasource.type=com.zaxxer.hikari.HikariDataSource Zugabe wird die folgende Ausnahme ausgelöst:

Also, was ist der einfachste Weg ist hikaricp meiner application.properties hinzufügen?

Answer 1

Sie erhalten unter Fehler.

Caused by: java.lang.AbstractMethodError: null at net.sourceforge.jtds.jdbc.JtdsConnection.isValid(JtdsConnection.java:2833)

Problem ist, dass net.sourceforge.jtds.jdbc.JtdsConnection nicht implementiert isValid so müssen Sie eine Verbindung Test-Abfrage angeben, um sicherzustellen, dass isValid Methode wird nicht aufgerufen. Probieren Sie es aus, indem Sie die Eigenschaft unten in der Datei application.properties hinzufügen.
