HikariCP - erro de ligação usando HikariDataSource

Question

Eu tenho um erro de ligação quando inicio o JBOSS AS 6.1 com um HikariDataSource.Como resolver isso?

Eu uso o hikariCP 1.3.3:

  <dependency>
     <groupId>com.zaxxer</groupId>
     <artifactId>HikariCP</artifactId>
     <version>1.3.3</version>
  </dependency>

Spring 3.2, JBOSS AS 6.1, Hibernate 3.6.6 (empacotado com JBOSS).Eu removi persistence.xml e configurei meu DataSource programaticamente usando LocalContainerEntityManagerFactoryBean abordagem de: http://www.baeldung.com/2011/12/13/the-persistence-layer-with-spring-3-1-and-jpa/

Meu DS eu configurei simplesmente:

   @Bean
   public DataSource dataSource() {
      HikariDataSource ds = new HikariDataSource(); //here i get the linkageError
      ds.setMaximumPoolSize(15);
      ds.setDataSourceClassName("com.microsoft.sqlserver.jdbc.SQLServerDataSource");
      ds.addDataSourceProperty("serverName", "localhost");
      ds.addDataSourceProperty("databaseName", "dbtest");
      ds.addDataSourceProperty("user", "dbtest");
      ds.addDataSourceProperty("password", "dbtest");
      ds.setPoolName("springHikariCp");
      return ds;
   }

E o final do stacktrace é:

Answer 1

No JBOSS AS 6.1 a solução para esse problema foi eu colocar HikariCP-1.3.5.jar \server\app\lib e no pom.xml defini-lo como provided.Quando migrei o aplicativo para WildFly 8 Hikari funciona como compile.

Answer 2

Eu sugeriria duas coisas.Primeiro, sugiro atualizar o HikariCP para a versão mais recente, 1.3.5.

Em segundo lugar, o erro parece estar relacionado ao carregador de classe, a exceção java.lang.ExceptionInInitializerError indica que a inicialização da classe estática para HikariConfig está sendo executado duas vezes de alguma forma.Isso só deve ser possível se houver dois carregadores de classe referenciando o mesmo jar HikariCP.Certifique-se de que o jar do HikariCP não esteja localizado no diretório da biblioteca global do JBoss, mas sim no diretório da biblioteca do contêiner do aplicativo.Se houver vários contêineres de aplicativos, o jar HikariCP deverá estar localizado em cada um deles individualmente.
