An error occurred while connecting the Android client to tomcat: connect failed: ECONNREFUSED (Connection refused), econnrefused

Public static final String BASE_URL = "http: // 127.0.0.1: 8090/HelloWord /"...;

Exception Caused by: libcore. io. ErrnoException: connect failed: ECONNREFUSED (Connection refused) will be thrown)

Solution:

String url = "http: // 127.0.0.1: 8090/HelloWord /"...;

Public static final String BASE_URL = "http: // 192.168.3.14: 8090/HelloWord "...;

The Host ip address cannot use localhost or 127.0.0.1. Use the real ip address.

Forced shutdown of tomcat is very easy to damage, and some inexplicable errors will be reported, but it can still be used. We can use it in general, no matter whether it reports an error.
