Java 重复链接键在投影REST响应中

为了在投影的Json框架中添加链接，我添加了以下类：

@Component
public class ResumeEntityProjectionResourceProcessor implements ResourceProcessor<Resource<ResumeEntity>> {

@Override
public Resource<ResumeEntity> process(Resource<ResumeEntity> resource) {

    UriComponents uriComponents = ServletUriComponentsBuilder.fromCurrentContextPath()
            .path("/api/entities/search/findEntities")
            .buildAndExpand(Long.toString(resource.getContent().getId()));
    resource.add(new Link(uriComponents.toUriString(), "findEntities"));

    return resource;
}

我是怎么做到只保留第一个标签的

预期结果

{
"_embedded": {
    "entities": [{
            "id": 1696,
            "reference": "aaaaaa",
            "_links": {
                "self": {
                    "href": "http://localhost:8080/myProject/api/entities/1696{?projection}",
                    "templated": true
                },
                "findByParametresValide": {
                    "href": "http://localhost:8080/myProject/api/entities/search/findEntities"
                }
            }
        }
    ]
}
}

谢谢

@Override
公共资源流程（资源）{
如果（resource.getLinks（）.isEmpty（））{
返回资源；
}
UriComponents UriComponents=ServletUriComponentsBuilder.fromCurrentContextPath（）
.path（“/api/entities/search/findEntities”）
.buildAndExpand（Long.toString（resource.getContent（）.getId（））；
添加（新链接（uriComponents.toUriString（），“findEntities”）；
返回资源；
}

尝试将链接添加到资源..为了解决此问题，我在下面的资源对象上添加了测试

@覆盖公共资源进程（资源资源）{if（resource.getLinks（）.isEmpty（））{return resource；}UriComponents UriComponents=ServletUriComponentsBuilder.fromCurrentContextPath（）.path（）(“/api/entities/search/findentials”）.buildAndExpand（Long.toString（resource.getContent（）.getId（））；resource.add（新链接（uriComponents.toUriString（），“findentials”）；return resource；}

{
"_embedded": {
    "entities": [{
            "id": 1696,
            "reference": "aaaaaa",
            "_links": {
                "self": {
                    "href": "http://localhost:8080/myProject/api/entities/1696{?projection}",
                    "templated": true
                },
                "findByParametresValide": {
                    "href": "http://localhost:8080/myProject/api/entities/search/findEntities"
                }
            }
        }
    ]
}
}

@Override
public Resource<ResumeEntity> process(Resource<ResumeEntity> resource) {
if (resource.getLinks().isEmpty()) { 
return resource; 
}
    UriComponents uriComponents = ServletUriComponentsBuilder.fromCurrentContextPath()
            .path("/api/entities/search/findEntities")
            .buildAndExpand(Long.toString(resource.getContent().getId()));
    resource.add(new Link(uriComponents.toUriString(), "findEntities"));

    return resource;
}
