在Springboot 中依赖Gson，项目启动时报错：
*************************** APPLICATION FAILED TO START *************************** 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:/D:/8_maven/mvnrepo/com/google/code/gson/gson/2.5/gson-2.5.jar!/com/google/gson/GsonBuilder.class It was loaded from the following location: file:/D:/8_maven/mvnrepo/com/google/code/gson/gson/2.5/gson-2.5.jar Action: Correct the classpath of your application so that it contains a single, compatible version of com.google.gson.GsonBuilder
解决办法：
将pom中依赖的Gson版本更换为2.6以上即可
<!-- https://mvnrepository.com/artifact/com.google.code.gson/gson --> <dependency> <groupId>com.google.code.gson</groupId> <artifactId>gson</artifactId> <version>2.8.6</version> </dependency>
