Jason中的Spring Data Rest -Disable自我链接（HAL）

篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Jason中的Spring Data Rest -Disable自我链接（HAL）相关的知识，希望对你有一定的参考价值。
我是spring-data-rest的新手。在我的应用程序中，当我进行休息调用时，我得到的json包括自我链接和外键表的链接。但我想要json而不是链接。我使用telosys工具生成器生成了我的代码。这是我的JSON，当我对数据库中的“商品”表进行REST调用时，我得到了什么：
{
"id" : 1,
"rate": 300,
"type": "item",
"shortDescription": "test",
"longDescription": "test test",
"_links": {
"self": {
"href": "http://localhost:8080/sportsrest/merchandises/1"
},
"listOfMerchandiseAttribute": {
"href": "http://localhost:8080/sportsrest/merchandises/1/listOfMerchandiseAttribute"
},
}
}
但是，我想获得listOfMerchandiseAttribute的JSON，而不是获取“listOfMerchandiseAttribute”的链接。 listOfMerchandiseAttribute是我在数据库中的另一个表
那就是我希望我的json像这样：
{
"id": 1,
"rate": 300,
"type": "item",
"shortDescription": "test",
"longDescription": "test test",
"_links": {
"self": {
"href": "http://localhost:8080/sportsrest/merchandises/1"
},
"listOfMerchandiseAttribute": {
"id": 1,
"attributeName": "testname",
"attributeValue": 50
},
}
}
当我在谷歌上搜索时，我得到了一些结果并根据它改变了ApplicationConfig.java文件，但我仍然得到链接而不是JSON。这是My ApplicationConfig文件。

任何人都可以帮我解决我的问题，并在链接上获取JSON。提前致谢。
答案
您应该确保listOfMerchandiseAttribute是您的域类的成员。然后默认转换为JSON应该在那里。 Spring Data REST将使用您当前的表示形式并添加超媒体。
另见Disable Hypertext Application Language (HAL) in JSON?
另一答案
您可以使用Excerpts（特别是针对此场景制作）。因为Spring的例子很有说服力而且在这里复制它是愚蠢的，我只想指出：https://docs.spring.io/spring-data/rest/docs/3.1.x/reference/html/#projections-excerpts.excerpting-commonly-accessed-data。 但是为了记录和方便，我将粘贴弹簧示例的主要部分：
@Projection(name = "inlineAddress", types = { Person.class })
interface InlineAddress {
String getFirstName();
String getLastName();
Address getAddress();
}
请参阅Projection javadoc，types表示投影类型所绑定的类型。
摘录可以这样使用：
@RepositoryRestResource(excerptProjection = InlineAddress.class)
interface PersonRepository extends CrudRepository<Person, Long> {}
为了得到这个：
{
"firstName" : "Frodo",
"lastName" : "Baggins",
"address" : {
"street": "Bag End",
"state": "The Shire",
"country": "Middle Earth"
},
"_links": ...
}
对你而言merchandise相当于Person而listOfMerchandiseAttribute相当于address。
如何摆脱_links
检查我在Disable Hypertext Application Language (HAL) in JSON?的答案。
最后的笔记
Spring正在不断发展，所以请注意，这至少可以解决：
spring-data-rest-webmvc 3.1.3.RELEASE
或者，如果您更喜欢春季靴子版本：
spring-boot-starter-parent 2.1.1.RELEASE
