In this article, the editor introduces "how to build a Ribbon program" in detail, the content is detailed, the steps are clear, and the details are handled properly. I hope this article "how to build a Ribbon program" can help you solve your doubts.

Previously, when you built the first Ribbon in eclipse alone, you only needed to add the following dependencies:

Com.netflix.ribbon ribbon 2.2.2 com.netflix.ribbon ribbon-httpclient 2.2.2

However, if the above dependency is built using the Maven command alone on the command line or in IDEA, an exception will be thrown with the following information:

[ERROR] symbol: variable ConfigurationManager [ERROR] location: class org.crazyit.cloud.TestPingUrlConfig [ERROR] / D:/s_book/Spring Cloud/codes/04/4.2/first-ribbon-client/src/main/java/org/crazyit/cloud/TestPingUrlConfig.java: [19Power17] symbol not found [ERROR] symbol: variable ConfigurationManager [ERROR] location: class org.crazyit.cloud.TestPingUrlConfig [ERROR] / D : / s_book/Spring Cloud/codes/04/4.2/first-ribbon-client/src/main/java/org/crazyit/cloud/TestPingUrlConfig.java: [23 ERROR 17] No symbol [ERROR] symbol: variable ConfigurationManager [ERROR] location: class org.crazyit.cloud.TestPingUrlConfig [ERROR] / D:/s_book/Spring Cloud/codes/04/4.2/first-ribbon-client/src/main/java/org/crazyit/cloud/TestRestClient Java: [14jue 17] cannot find the symbol [ERROR] symbol: variable ConfigurationManager [ERROR] location: class org.crazyit.cloud.TestRestClient [ERROR] / D:/s_book/Spring Cloud/codes/04/4.2/first-ribbon-client/src/main/java/org/crazyit/cloud/TestRestClient.java: [25pied 49] cannot access com.google.common.reflect.ypeToken [error] cannot find com.google.common.reflect. The class file [ERROR] / D:/s_book/Spring Cloud/codes/04/4.2/first-ribbon-client/src/main/java/org/crazyit/cloud/MyPingTest.java of TypeToken cannot find the symbol [ERROR] symbol: variable ConfigurationManager

For the solution, use eclispe or modify pom.xml. The modified pom.xml content is as follows:

Com.netflix.ribbon ribbon-core 2.2.2 com.netflix.ribbon ribbon-loadbalancer 2.2.2 com.netflix.archaius archaius-core 0.7.5 commons-configuration commons-configuration 1.9 com.netflix.ribbon ribbon-httpclient 2.2.2 com.google.guava guava 18.0

I don't know the reason for this at the moment. I guess there is something wrong with eclipse's Maven plug-in, which automatically introduces a lot of dependencies.
