问题描述 投票：0回答：2

我的项目在https://github.com/murillocg/SpringBootTest

当我访问任何 URI，如本地主机/视频时，得到以下响应：

{"_links":{"search":{
        "href":"http://localhost:8080/video/search"
    }
},

我在这个项目中做错了什么？

这个项目基于 https://github.com/juleswhite/mobilecloud-15/tree/master/examples/6-VideoServiceWithDataRest，它有效但使用 Gradle。

我想指出@JsonIgnore 对我不起作用。我在...时收到此错误

(a) 我将 Accept 标头指定为“application/x-spring-data-verbose+json” (b) 我在一个非常普通的 JPA 实体上执行此操作，其中有几个字段没有指向其他 JPA 实体的链接。

我正在使用 Spring Data 2.4.1.

大家的熏陶，看来这是Spring Data的问题。 DATAREST-733

我认为这是在说您在要进行 JSON 化的实体中的某处存在循环关系。当我有一个具有 

User
字段的 
lastModifiedBy
实体时，我遇到过这个问题。当用户更新自己时，
lastModifiedBy
指向同一个用户对象。为了解决这个问题，我不得不用

注释用户类 
@JsonIgnoreProperties({ "createdBy", "lastModifiedBy" })
