2.报错解决

原因：缺少jackson相关依赖
引入以下两个依赖解决上述报错：

      <dependency>
          <groupId>com.fasterxml.jackson.core</groupId>
          <artifactId>jackson-core</artifactId>
          <version>2.17.0</version>
      </dependency>
      <dependency>

          <artifactId>jackson-annotations</artifactId>
          <version>2.17.0</version>
      </dependency>
