Spring引导响应REST服务错误

Question

我的项目是在https://github.com/murillocg/SpringBootTest

当我访问任何URI时，如localhost/video，得到以下响应:

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

我在这个项目中做错了什么?

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

Answer 1

我想注意@JsonIgnore不适合我。我得到这个错误时…

(a)我指定Accept报头为"application/x-spring-data-verbose+json"(b)我在一个非常普通的JPA实体上这样做，其中有几个字段没有链接到其他JPA实体。

我正在使用Spring Data 2.4.1.

对于每个人来说，这似乎是Spring Data的问题。塔尔- 733

Answer 2

我认为它是说你在要jsonify的实体中有一个循环关系。当我有一个具有lastModifiedBy字段的User实体时，我遇到了这个问题。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，我必须用

注释User类

@JsonIgnoreProperties({ "createdBy", "lastModifiedBy" })
