将Spring属性占位符与Jersey @Path和@ApplicationPath一起使用

因此，这是答案的一半（或者可能是一个完整的答案，具体取决于解决方案

@ApplicationPath

要了解以下解决方案，您应该首先了解Jersey的内部构造。当我们加载应用程序时，Jersey将构建所有资源的模型。资源的所有信息都封装在此模型中。Jersey使用此模型来处理请求，而不是尝试处理每个请求上的资源，而是将有关资源的所有信息保留在模型中并进行处理会更快。

借助这种架构，Jersey还允许我们使用与内部使用的相同API
来以编程方式构建资源，以保存模型属性。除了 构建 资源模型之外，我们还可以使用来 修改
现有模型

ModelProcessor

在中

ModelProcessor

PropertyResolver

@Autowiredprivate PropertyResolver propertyResolver;private ResourceModel processResourceModel(ResourceModel resourceModel) {    ResourceModel.Builder newResourceModelBuilder = new ResourceModel.Builder(false);    for (final Resource resource : resourceModel.getResources()) {        final Resource.Builder resourceBuilder = Resource.builder(resource);        String resolvedResourcePath = processPropertyPlaceholder(resource);        resourceBuilder.path(resolvedResourcePath);        // handle child resources        for (Resource childResource : resource.getChildResources()) { String resolvedChildPath = processPropertyPlaceholder(childResource); final Resource.Builder childResourceBuilder = Resource.builder(childResource); childResourceBuilder.path(resolvedChildPath);     resourceBuilder.addChildResource(childResourceBuilder.build());        }        newResourceModelBuilder.addResource(resourceBuilder.build());    }    return newResourceModelBuilder.build();}private String processPropertyPlaceholder(Resource resource) {    String ogPath = resource.getPath();    return propertyResolver.resolvePlaceholders(ogPath);}

就资源模型API而言

• 这是一个

  Resource

@Path("resource")public class SomeResource {@GETpublic String get() {}}

其 未 注释的资源方法

@Path

ResourceMethod

• 这是上述内容的 孩子

  Resource

  ，

  Resource

  因为带有注释

  @Path

  。

@GET@Path("child-resource")public String get() {}

此信息应使您对上述实现的工作原理有所了解。

以下是使用Jersey测试框架的完整测试。使用以下类路径属性文件

app.properties

resource=resourcesub.resource=sub-resourcesub.resource.locator=sub-resource-locator

您可以像执行其他任何JUnit测试一样运行以下命令。

同样，现在我考虑了一下，我可以看到一种解决resolve的方法

@ApplicationPath

WebAppInitializer

@ApplicationPath

UDPATE

如果您使用的是Spring
Boot，那么通过该

spring.jersey.applicationPath
