1、如果写错了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:588)  
at com.rabbitmq.client.ConnectionFactory.newConnection(ConnectionFactory.java:612)  
at com.aaa.test.Send.main(Send.java:19)

2 、如果写错了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.impl.FrameHandlerFactory.create(FrameHandlerFactory.java:32)  
at com.rabbitmq.client.ConnectionFactory.newConnection(ConnectionFactory.java:588)  
at com.rabbitmq.client.ConnectionFactory.newConnection(ConnectionFactory.java:612)

3、如果写错端口PORT（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 com.rabbitmq.client.ConnectionFactory.newConnection(ConnectionFactory.java:612)  
at com.aaa.test.Send.main(Send.java:19)

4、如果写错用户名或者密码，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)
