weblogic创建连接池The Network Adapter could not establish the connection

Question

weblogic创建连接池的时候出现 Cannot create PoolableConnectionFactory(Io 异常: The Network Adapter could not establish the connection )
代码是本地电脑，数据库也装在本地，本地plsql能连上，创建连接池也可以测试通过，但是起代码后就报错

本地plsql能连上，说名监听服务没问题，地址没问题，防火墙不用管

监听文件
LISTENER =

  (DESCRIPTION_LIST =
    (DESCRIPTION =
         (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
    )
  )

连接池链接：
jdbc:oracle:thin:@127.0.0.1:1521:xxxx
