大家好，又见面了，我是全栈君。
1、假设写错了host （如：factory.setHost(“locathost”); ）报错：
Exception in thread “main” 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:612)
at com.aaa.test.Send.main(Send.java:19)
2、假设写错了HOST的IP（如：factory.setHost(“192.168.1.10”); ）无此地址， 报错：
Exception in thread “main” java.net.ConnectException: Connection timed out: connect
at java.net.PlainSocketImpl.socketConnect(Native Method)
at java.net.PlainSocketImpl.doConnect(PlainSocketImpl.java:351)
at java.net.PlainSocketImpl.connectToAddress(PlainSocketImpl.java:213)

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 “main” java.net.ConnectException: Connection refused: connect
at java.net.PlainSocketImpl.socketConnect(Native Method)
at java.net.PlainSocketImpl.doConnect(PlainSocketImpl.java:351)
at java.net.PlainSocketImpl.connectToAddress(PlainSocketImpl.java:213)

4、假设写错username或者password，报错：
Exception in thread “main” com.rabbitmq.client.AuthenticationFailureException: ACCESS_REFUSED – Login was refused using authentication mechanism PLAIN. For details see the broker logfile.
at com.rabbitmq.client.impl.AMQConnection.start(AMQConnection.java:338)
at com.rabbitmq.client.ConnectionFactory.newConnection(ConnectionFactory.java:590)
at com.rabbitmq.client.ConnectionFactory.newConnection(ConnectionFactory.java:612)
at com.aaa.test.Send.main(Send.java:19)
