哪个JAR文件包含JsonProcessingException类？ [英] Which JAR file contains the JsonProcessingException class?

问题描述

当我尝试使用带有以下jar文件的Jackson 2.1.1时（在Spring 3.2.2中），

When I try to use Jackson 2.1.1 with the following jar files (in Spring 3.2.2),

• jackson-core -2.1.1.jar


• jackson-annotations-2.1.1.jar


• jackson-databind-2.1.1.jar

我收到以下异常。

java.lang .ClassNotFoundException：
org.codehaus.jackson.JsonProcessingException

java.lang.ClassNotFoundException: org.codehaus.jackson.JsonProcessingException

所以我认为，类 JsonProcessingException 包含在 jackson-core-asl-2.1.1.jar 文件中（虽然我不太确定）但我看不到这个文件在下载中。那么在哪里获取此文件来解决该异常？

So I think, the class JsonProcessingException is contained by the jackson-core-asl-2.1.1.jar file (I'm not quite sure though) but I cannot see this file in the download. So where to get this file to resolve that exception?

jackson-all-1.9.8.jar 包含必要的类，包括类 org.codehaus.jackson.JsonProcessingException 和JSON也可以正常工作，但我不确定这是完全兼容的，因为我使用Jackson 2.1.1中的类进行对象映射。因此，我正在寻找 jackson-core-asl-2.1.1.jar 文件，但我看不到这样的JAR文件。我只能看到 1.xx 版本此处。

jackson-all-1.9.8.jar contains necessary classes including the class org.codehaus.jackson.JsonProcessingException and JSON also works fine but I'm not sure this is perfectly compatible as I'm using classes from Jackson 2.1.1 for object mapping. Therefore I'm looking for the jackson-core-asl-2.1.1.jar file but I can't see such a JAR file. I can only see 1.x.x versions here.

推荐答案

在2.1.2版中，该类名为 com.fasterxml.jackson。 core.JsonProcessingException ，它位于jackson-core jar中。杰克逊更改了2.0版的包装以及其他许多内容。

In version 2.1.2, that class is called com.fasterxml.jackson.core.JsonProcessingException, and it's in the jackson-core jar. Jackson changed its packaging for version 2.0, along with numerous other things.

似乎你有一些代码是针对旧版本的Jackson编写的，并且正在尝试以旧名称加载该类。您需要更新此代码，或使用旧版本的Jackson。

It seems you have some code that was written against an older version of Jackson, and is trying to load the class under an old name. You will need to either update this code, or use an old version of Jackson.
