在 Spring Boot + Spring Data Rest 中反序列化时忽略带有 @JsonProperty 的字段
Fields with @JsonProperty are ignored on deserialization in Spring Boot + Spring Data Rest
我发现在 Spring Boot + Spring Data Rest 中，带有@JsonProperty 的字段在反序列化时仍然被忽略。不使用 Spring 引导，错误已修复。查看问题跟踪器：https://jira.spring.io/browse/DATAREST-320
我创建了一个最小的演示项目来重现 Spring Boot 1.2.3.RELEASE 中的错误。快捷键：https://github.com/cdcorg/JsonPropertyBug/blob/master/src/main/java/demothree/domain/Entity.java#L21
启用@JsonProperty 将无法更改 属性（通过使用 HTTP PUT）
如果我设置
spring.jackson.mapper.USE_ANNOTATIONS=false
并尝试更新属性，Spring Data Rest 会说：

一个很奇怪的解决方案：
在我切换回 Spring Data Rest 2.2.1（包含在 Spring Boot 1.2.1.RELEASE 中）后，HTTP PUT 现在可以正常工作。您可以通过更改我的错误演示项目的 POM 文件来验证这一点。
现在我很困惑：
为什么我没有像 Runar Botten 那样使用 Spring Data Rest 2.2.1 重现相同的错误？
为什么我使用应该修复该问题的后一版本 (2.2.2) 会遇到该错误？？
