原因
因爲jackson依賴版本問題
<dependency>
<groupId>com.fasterxml.jackson.datatype</groupId>
<artifactId>jackson-datatype-guava</artifactId>
<version>2.5.3</version>
</dependency>
解決辦法
- 到mvnrepository搜索
jackson datatype，使用支持的版本 - 修改pom.xml文件中jackson版本號爲支持的版本號
<dependency>
<groupId>com.fasterxml.jackson.datatype</groupId>
<artifactId>jackson-datatype-guava</artifactId>
<version>2.10.1</version>
</dependency>
