  那不是错误 . JavaEE 7强制要求DefaultDataSource . 仅仅因为你没有资源引用它并不意味着你不查找它，所以Wildfly必须提供java：comp / DefaultDataSource，它映射到ExampleDS：

  EE.5.19 Default Data Source
  The Java EE Platform requires that a Java EE Product Provider provide a database
  in the operational environment (see Section EE.2.6, “Database”). The Java EE
  Product Provider must also provide a preconfigured, default data source for use by
  the application in accessing this database.
  
  The Java EE Product Provider must make the default data source accessible to
  the application under the JNDI name java:comp/DefaultDataSource.
  
  The Application Component Provider or Deployer may explicitly bind a
  DataSource resource reference to the default data source using the lookup element
  of the Resource annotation or the lookup-name element of the resource-ref
  deployment descriptor element. For example,
  
  @Resource(lookup="java:comp/DefaultDataSource")
  DataSource myDS;
  
  In the absence of such a binding, the mapping of the reference will default to
  the product's default data source.
  
  For example, the following will map to a preconfigured data source for the
  product's default database:
  
  @Resource
  DataSource myDS;
