SpringCloud学习笔记-Eureka搭建过程中的出现问题
问题1:Gson包冲突,启动Server的时候报错,具体信息描述如下:
Description: An attempt was made to call a method that does not exist. The attempt was made from the following location: java.lang.invoke.MethodHandleNatives.resolve(Native Method) The following method did not exist: com.google.gson.GsonBuilder.setLenient()Lcom/google/gson/GsonBuilder; The method's class, com.google.gson.GsonBuilder, is available from the following locations: jar:file:/C:/Users/farida/.m2/repository/com/google/code/gson/gson/2.1/gson-2.1.jar!/com/google/gson/GsonBuilder.class It was loaded from the following location: file:/C:/Users/farida/.m2/repository/com/google/code/gson/gson/2.1/gson-2.1.jar Action: Correct the classpath of your application so that it contains a single, compatible version of com.google.gson.GsonBuilder
解决方案:排除eureka自身所使用的gson包
