我有一个简单的Spring MVC应用程序，它使用RestTemplate类对ReST服务进行Ajax调用。模式中的一些元素以大写字母开头。小写字母的2个元素（代码，消息）不会造成任何问题。由JAXB生成的类具有@XmlElement注释和name属性。这似乎被忽略了。我读过JaxbAnnotationIntrospector需要使用，但没有任何更改使生效。见下面的课。我已经尝试在Spring配置中为RestTemplate添加一个bean类定义，添加一个对象映射器，但没有任何帮助。见OTPRO元件上错误在堆栈跟踪的前几行：带有大写元素名称的Spring RestTemplate失败

注意：我不想简单地忽略大写元素。
它看起来像服务正在返回JSON，你试图将其反序列化为XML？ – david
这些类是从XML模式生成的，但请求/响应是JSON。此外，响应中返回的“代码”和“消息”字段没有问题。这些名字是小写的。只有大写字段会导致“无法读取JSON：无法识别的字段”错误。 –
我想你需要添加一些杰克逊特定的注释到那些有问题的领域。 – david
