java-spring的正确版本或杰克逊是什么？
作者：互联网
我正在使用杰克逊转换器(MappingJacksonHttpMessageConverter)来使用和产生来自spring控制器的json数据.但是在调用控制器时会引发以下异常.
Caused by: java.lang.NoSuchMethodError: org.codehaus.jackson.type.JavaType.isConcrete()Z

我可以在spring-web pom文件中看到jackson版本被提到为1.4.2,并且我仍然使用过它关于未找到的方法抛出异常.我使用的版本正确吗？
解决方法:
您似乎缺少杰克逊核心的依赖关系.您还需要杰克逊映射器.
1.4.x版本应该很好,尽管将其升级到最新版本也不会受到损害.
