基本路径没有出现在资源处理器自定义链接中

Question

在Spring数据REST中，我使用资源处理器创建自定义链接：

@Component
public class ServiceInstanceProcessor
        implements ResourceProcessor<Resource<ServiceInstance>> {

    @Override
    public Resource<ServiceInstance> process(Resource<ServiceInstance> resource) {
        Long id = resource.getContent().getId();
        ServiceInstanceController controller =
                methodOn(ServiceInstanceController.class);

        resource.add(linkTo(controller.getNodeSummary(id))
                .withRel("nodeSummary"));
        resource.add(linkTo(controller.getHealthBreakdown(id))
                .withRel("healthBreakdown"));
        resource.add(linkTo(controller.getRotationBreakdown(id))
                .withRel("rotationBreakdown"));
        return resource;
    }
}

然而，即使我已将控制器标记为@BasePathAwareController，并且即使默认链接包含基本路径，生成的链接也不包括基本路径：

{
  ...

  "_links" : {
  "self" : {
    "href" : "http://localhost:8080/api/serviceInstances/101"
  },
  "serviceInstance" : {
    "href" : "http://localhost:8080/api/serviceInstances/101{?projection}",
    "templated" : true
  },
  "nodeSummary" : {
    "href" : "http://localhost:8080/serviceInstances/101/nodeSummary"
  },
  "healthBreakdown" : {
    "href" : "http://localhost:8080/serviceInstances/101/healthBreakdown"
  },
  "rotationBreakdown" : {
    "href" : "http://localhost:8080/serviceInstances/101/rotationBreakdown"
  },

  ...
}

}

我还需要做什么才能让基本路径出现在链接中？

Answer 1

我认为这与错误控制器有关，LinkBuilder没有考虑Spring Data REST的基本路径，并且自定义控制器更改的基本路径没有显示在HAL中

作为解决方法，我接下来要做：

@Autowired
private final RepositoryRestConfiguration config;

private Link fixLinkSelf(Object invocationValue) {
    return fixLinkTo(invocationValue).withSelfRel();
}

@SneakyThrows
private Link fixLinkTo(Object invocationValue) {
    UriComponentsBuilder uriComponentsBuilder = linkTo(invocationValue).toUriComponentsBuilder();
    URL url = new URL(uriComponentsBuilder.toUriString());
    uriComponentsBuilder.replacePath(config.getBasePath() + url.getPath());
    return new Link(uriComponentsBuilder.toUriString());
}

用法与< code>linkTo相同:

resources.add(fixLinkSelf(methodOn(VoteController.class).history()));    
resources.add(fixLinkTo(methodOn(VoteController.class).current()).withRel("current"));

基于当前addPath请求的简单情况的其他解决方法：

new Link(ServletUriComponentsBuilder.fromCurrentRequest().path(addPath).build().toUriString())
