rabbitmq连接測试[通俗易懂]

1、假设写错了host （如：factory.setHost(&＃8220;locathost&＃8221;); ）报错：

Exception in thread &＃8220;main&＃8221; java.net.UnknownHostException: locathost
at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:195)
at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:366)
at java.net.Socket.connect(Socket.java:529)
at com.rabbitmq.client.impl.FrameHandlerFactory.create(FrameHandlerFactory.java:32)
at com.rabbitmq.client.ConnectionFactory.newConnection(ConnectionFactory.java:588)
at com.rabbitmq.client.ConnectionFactory.newConnection(ConnectionFactory.java:612)
at com.aaa.test.Send.main(Send.java:19)

2、假设写错了HOST的IP（如：factory.setHost(&＃8220;192.168.1.10&＃8221;); ）无此地址， 报错：

Exception in thread &＃8220;main&＃8221; java.net.ConnectException: Connection timed out: connect

at java.net.PlainSocketImpl.doConnect(PlainSocketImpl.java:351)

at com.rabbitmq.client.ConnectionFactory.newConnection(ConnectionFactory.java:612)
at com.aaatest.Send.main(Send.java:19)

3、假设写错portPORT（如：factory.setPort(5678);） 报错：

Exception in thread &＃8220;main&＃8221; java.net.ConnectException: Connection refused: connect
at java.net.PlainSocketImpl.socketConnect(Native Method)
at java.net.PlainSocketImpl.doConnect(PlainSocketImpl.java:351)

at com.aaa.test.Send.main(Send.java:19)

4、假设写错username或者password，报错：

Exception in thread &＃8220;main&＃8221; com.rabbitmq.client.AuthenticationFailureException: ACCESS_REFUSED &＃8211; Login was refused using authentication mechanism PLAIN. For details see the broker logfile.
