I was getting the exactly same issue. I was using Maven for dependency management and had added dependency for Hymanson-databind module only like this
我遇到了完全相同的问题。我正在使用 Maven 进行依赖管理，并且只像这样为 Hymanson-databind 模块添加了依赖
<dependency>
<groupId>com.fasterxml.Hymanson.core</groupId>
<artifactId>Hymanson-databind</artifactId>
<version>${Hymanson.version}</version>
</dependency>
and then I resolved it by doing this.. I added its transitive dependencies explicitly with the same Hymanson.version mentioned for each of them in the pom.xml file, as guided here
然后我通过这样做解决了它..我按照在 pom.xml 文件中为每个人提到的相同 Hymanson.version 显式添加了它的传递依赖项，如指导here
<dependency>
<groupId>com.fasterxml.Hymanson.core</groupId>
<artifactId>Hymanson-annotations</artifactId>
<version>${Hymanson.version}</version>
</dependency>
<dependency>
<groupId>com.fasterxml.Hymanson.core</groupId>
<artifactId>Hymanson-core</artifactId>
<version>${Hymanson.version}</version>
</dependency>

I had the same issue. There was some incompatibility between the Hymanson-version 2.6.3 and another dependency (graphaware-framework-embedded).
我遇到过同样的问题。Hymanson-version 2.6.3 和另一个依赖项（graphaware-framework-embedded）之间存在一些不兼容。
I could resolve the issue by simply removing the dependency on Hymansonin my own pom and just let the other dependency load whatever Hymanson-version it needed.
我可以通过简单地在我自己的 pom 中删除对 jackson 的依赖来解决这个问题，并让其他依赖加载它需要的任何 Hymanson 版本。

I came here with a similar issue on Google App Engine. Here is how I fixed it.
我在 Google App Engine 上遇到了类似的问题。这是我修复它的方法。
First I ran:
首先我跑了：
mvn dependency:tree
To find who is using the older version. I then excluded that from the offending dependency like so:
查找谁在使用旧版本。然后我将其从有问题的依赖项中排除，如下所示：
<dependency>
<groupId>com.google.appengine.tools</groupId>
<artifactId>appengine-gcs-client</artifactId>
<version>0.6</version>
<exclusions>
<exclusion>
<groupId>com.fasterxml.Hymanson.core</groupId>
<artifactId>Hymanson-core</artifactId>
</exclusion>
</exclusions>
</dependency>
Next I added the newer version of the dependency in my pom.xml:
接下来，我在 pom.xml 中添加了更新版本的依赖项：
<dependency>
<groupId>com.fasterxml.Hymanson.core</groupId>
<artifactId>Hymanson-core</artifactId>
<version>2.8.7</version>
</dependency>
Hope this help others who stumble here.
希望这能帮助其他在这里绊倒的人。

I faced the same issue just now while upgrading my project from spring 3 to 4.1.6.
我刚刚在将我的项目从 spring 3 升级到 4.1.6 时遇到了同样的问题。
A little background for reference, just in case if it helps anyone running into same issue===> First, it prompted me with error for mappingHymansonconverter vs mappingHymanson2converter since the former doesn't exist anymore with spring 4. Once I changed those references in code, I ran into issue with my dispatcher servlet since it had xsd definitions from spring 3 support. Once that's corrected, my last step in journey was this error which you all faced as well.
一些参考背景，以防万一它可以帮助任何遇到相同问题的人===> 首先，它提示我 mappingHymansonconverter 与 mappingHymanson2converter 的错误，因为前者在 spring 4 中不再存在。一旦我更改了这些引用代码，我遇到了调度程序 servlet 的问题，因为它具有来自 spring 3 支持的 xsd 定义。一旦纠正，我旅程的最后一步就是你们都面临的这个错误。
My solution: I had older versions of following jars: Hymanson-annotations, Hymanson-core, Hymanson-databind, Hymanson-core-asl, Hymanson-mapper-asl
我的解决方案：我有以下 jars 的旧版本：Hymanson-annotations、Hymanson-core、Hymanson-databind、Hymanson-core-asl、Hymanson-mapper-asl
I upgraded first 3 jars to 2.10.0.pr1 release and last 2 to 1.9.13 release.
我将前 3 个 jar 升级到 2.10.0.pr1 版本，最后 2 个升级到 1.9.13 版本。
I also had one more older jar i.e.com.fasterxml.Hymanson.core.jar which I had to remove as well. Anyways, as error suggested this was the key reason for the mismatch (Like Tobias said in comment prior to mine)
我还有一个更旧的 jar iecom.fasterxml.Hymanson.core.jar，我也不得不将其删除。无论如何，错误表明这是不匹配的关键原因（就像托比亚斯在我之前的评论中所说的那样）
I think only last paragraph is important from this particular question point of view, but I am hoping my narration of issues faced leading up to that may help someone saving 4-5 hrs :) Cheers, folks!
我认为从这个特定问题的角度来看，只有最后一段很重要，但我希望我对面临的问题的叙述可以帮助某人节省 4-5 小时 :) 干杯，伙计们！
