CAS报错I/O error on GET request for “http://localhost:8888/casconfigserver/cas/native“: Connection refused (Connection refused);

cas在部署的报错：

Caused by: org.springframework.web.client.ResourceAccessException: I/O error on GET request for "http://localhost:8888/casconfigserver/cas/native": Connection refused (Connection refused); nested exception is java.net.ConnectException: Connection refused (Connection refused)

解决方案

在CAS的bootstrap.properties中

spring.cloud.config.uri=http://casuser:Mellon@localhost:8888/casconfigserver

修改为

spring.cloud.config.uri=http://localhost:8888/casconfigserver
