Question

我试图在Spring 3.0.6中使用Jackson API时遇到异常。我有v1.8.9的jackson jars（core-asl，mapper-asl）进入类路径但仍然由于一些冲突的jar我面临错误::

Answer 1

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。

Answer 2

感谢您的回复。但是，我可以解决一些R＆amp; D的问题...我不需要转到Jackson v1.4.2，而是在JBoss配置本身稍作修改时使用了相同的版本。

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

这里JBoss使用自己的Jackson API版本（虽然我们在classpath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）。对于mapper jar 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....：）

使用Spring和Jackson API的BeanCreationException
