查了一些解决方案，但是最后发现这个报错是因为：在pom引用了jackson相关包，但没有引用完整导致的
<dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>2.13.3</version> <scope>compile</scope></dependency>这个Jackson 是当前用的比较广泛的，用来序列化和反序列化 json 的 Java 的开源框架。
解决方案：引用完整的依赖
<dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <exclusions> <exclusion> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-annotations</artifactId> </exclusion> </exclusions></dependency><dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-annotations</artifactId> <version>2.9.8</version></dependency>来源地址：https://blog.csdn.net/qq_43408367/article/details/128361675
