当我启动 JBOSS AS 6.1 时出现链接错误HikariDataSource。如何解决这个问题？

我使用 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（与 JBOSS 捆绑）。我删除了 persistence.xml 并使用以下LocalContainerEntityManagerFactoryBean方法以编程方式配置了我的数据源：http ://www.baeldung.com/2011/12/13/the-persistence-layer-with-spring-3-1-and-jpa/

我的 DS 我配置简单：

   @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;
   }

堆栈跟踪的结尾是：

我会建议两件事。首先，我建议将 HikariCP 升级到最新版本 1.3.5。

其次，错误似乎与类加载器有关，异常java.lang.ExceptionInInitializerError表明静态类初始化以HikariConfig某种方式执行了两次。只有当有两个类加载器引用同一个 HikariCP jar 时，这才是可能的。确保 HikariCP jar 不在 JBoss 的全局库目录中，而是位于应用程序的容器库目录中。如果有多个应用程序容器，HikariCP jar 应该分别位于每个容器中。

在 JBOSS AS 6.1 上，这个问题的解决方案是我把 HikariCP-1.3.5.jar \server\app\lib 和 pom.xml 设置为provided. 当我将应用程序迁移到 WildFly 8 时，Hikari 的工作方式为compile.
