SpringBoot集成第三方jar包启动报错

背景

对接某第三方jar包，集成到SpringBoot里面跑测试demo，启动报错

报错BUG

2020-03-27 15:50:07.084 [main] DEBUG o.s.b.d.LoggingFailureAnalysisReporter - Application failed to start due to an exception
java.lang.NoSuchMethodError: com.google.gson.GsonBuilder.setLenient()Lcom/google/gson/GsonBuilder;

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)

    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:/D:/maven_repository/cn/coralglobal/coupang-open-api/1.0.13/coupang-open-api-1.0.13.jar!/com/google/gson/GsonBuilder.class

It was loaded from the following location:

    file:/D:/maven_repository/cn/coralglobal/coupang-open-api/1.0.13/coupang-open-api-1.0.13.jar


Action:

Correct the classpath of your application so that it contains a single, compatible version of com.google.gson.GsonBuilder

排查问题

查看了很多资料说是 gson版本冲突什么的，我排除 spring-boot-starter-web 里面的gson还是报错

解决方案

@SpringBootApplication(exclude = {GsonAutoConfiguration.class})

SpringBoot排除自动装配某个class来解决jar包冲突
