Question

我们尝试从Spring 3.1.2迁移到Spring 4.1.2 迁移后，运行tomcat时我们面临异常，这个问题是由我们的spring-jms依赖引起的。据我所知，这个类“MappingJacksonMessageConverter”仅在春季3中可用，在春季4，该类是MappingJackson 2 MessageConverter。我不确定Spring代码的哪一部分正在加载此类MappingJacksonMessageConverter。

也许你有一些错误版本的某些依赖项，也许它们没有被迁移，所以你必须在maven中心看到Spring 4.1.2的依赖项表，这个表包含与Spring版本兼容的最低版本你想。

迁移问题从春季3.1.2到春季4
