原因

因为jackson依赖版本问题

<dependency><groupId>com.fasterxml.jackson.datatypegroupId><artifactId>jackson-datatype-guavaartifactId><version>2.5.3version>
dependency>

解决办法

• 到mvnrepository搜索 jackson datatype &＃xff0c;使用支持的版本
• 修改pom.xml文件中jackson版本号为支持的版本号

<dependency><groupId>com.fasterxml.jackson.datatypegroupId><artifactId>jackson-datatype-guavaartifactId><version>2.10.1version>
