在尝试将 Jackson API 与 Spring 3.0.6 一起使用时，我遇到了以下异常。我在类路径中有 v1.8.9（core-asl，mapper-asl）的杰克逊罐子，但仍然由于一些冲突的罐子我面临错误::

Jackson 对 Spring 3.0.6 的正确版本依赖是 1.4.2（每个 Spring 的 pom），尝试用这个版本替换 1.8.9，它应该可以正常工作。

感谢您的回复。但是，我可以通过一些研发来解决这个问题……我不需要去 Jackson v1.4.2，而是使用相同的版本，并在 JBoss 配置本身中稍作修改。

在 JBoss 中，转到 modules/org/codehaus/jackson/jackson-core-asl/main/

这里 JBoss 使用它自己的 Jackson API 版本（尽管我们在类路径中有不同的版本）。所以我复制了 v1.8.9 并在 module.xml 中进行了相应的更改（在同一目录中）。mapper jars v1.8.9 重复了类似的事情。

有了这个，我可以解决问题并再次运行...... :)
