HikariCP - Error de vinculación al utilizar HikariDataSource

Question

Tengo un error de vinculación cuando inicio JBOSS AS 6.1 con un HikariDataSource.¿Cómo solucionar esto?

Yo uso 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 (incluido con JBOSS).Eliminé persistence.xml y configuré mi DataSource mediante programación usando LocalContainerEntityManagerFactoryBean acercamiento desde: http://www.baeldung.com/2011/12/13/the-persistence-layer-with-spring-3-1-and-jpa/

Mi DS lo configuré simplemente:

   @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;
   }

Y el final de stacktrace es:

Answer 1

En JBOSS AS 6.1, la solución a este problema fue poner HikariCP-1.3.5.jar \server\app\lib y en pom.xml configurarlo como provided.Cuando migré la aplicación a WildFly 8, Hikari funciona como compile.

Answer 2

Yo sugeriría dos cosas.Primero, sugiero actualizar HikariCP a la última versión, 1.3.5.

En segundo lugar, el error parece estar relacionado con el cargador de clases, la excepción java.lang.ExceptionInInitializerError indica que la inicialización de clase estática para HikariConfig se está ejecutando dos veces de alguna manera.Esto sólo debería ser posible si hay dos cargadores de clases que hacen referencia al mismo contenedor HikariCP.Asegúrese de que el archivo jar de HikariCP no esté ubicado en el directorio de la biblioteca global de JBoss, sino en el directorio de la biblioteca contenedora de la aplicación.Si hay varios contenedores de aplicaciones, el frasco de HikariCP debe ubicarse en cada uno de ellos de forma individual.
