Spring JPA Not supported by BasicDataSource

详细错误：

Exception in thread "main" java.lang.UnsupportedOperationException: Not supported by BasicDataSource
    at org.apache.commons.dbcp.BasicDataSource.getConnection(BasicDataSource.java:1062)
    at org.hibernate.ejb.connection.InjectedDataSourceConnectionProvider.getConnection(InjectedDataSourceConnectionProvider.java:68)
    at org.hibernate.jdbc.ConnectionManager.openConnection(ConnectionManager.java:446)
    at org.hibernate.jdbc.ConnectionManager.getConnection(ConnectionManager.java:167)
    at org.hibernate.jdbc.AbstractBatcher.prepareQueryStatement(AbstractBatcher.java:161)

    at org.hibernate.loader.Loader.doQuery(Loader.java:801)
    at org.hibernate.loader.Loader.doQueryAndInitializeNonLazyCollections(Loader.java:274)

 

原因是在 application.xml 和persistence.xml两个文件中都 配置了数据源，删除一个就好了
