org.codehaus.jackson 是 Jackson 的旧版本.

com.fasterxml.jackson 代表新项目和包.

我建议从您的 POM 中删除 org.codehaus.jackson 引用，重新构建并查找错误(不太可能但可能).

I would recommend removing org.codehaus.jackson references from your POM, re-building and looking for errors (not likely but possible).

如果您找到了，您可以使用已弃用的 API 将代码调整为较新的 Jackson 版本的 API.

If you find any, you can adapt the code using deprecated API to the newer Jackson version's API.
