如何在使用Spring Boot时升级Spring HATEOAS？

Question

我正在阅读关于Spring HATEOAS的内容，似乎在1.0版本中有许多更改。我想切换到1.0。

然而，我的pom.xml文件正在引用0.25.2版本。

我尝试使用

  <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-hateoas</artifactId>
            <version>2.2.0.RELEASE</version>
        </dependency>

它仍然会拉取0.25.2版本。如果我明确地放入

标签，它将使用明确指定的版本。

<dependency>
        <groupId>org.springframework.hateoas</groupId>
        <artifactId>spring-hateoas</artifactId>
        <version>1.0.0.RELEASE</version>
        <scope>compile</scope>
    </dependency>

它在1.0版本中可以引入，但我遇到了运行时错误。

Caused by: java.lang.ClassNotFoundException: org.springframework.hateoas.RelProvider
    at java.base/jdk.internal.loader.BuiltinClassLoader.loadClass(BuiltinClassLoader.java:583) ~[na:na]
    at java.base/jdk.internal.loader.ClassLoaders$AppClassLoader.loadClass(ClassLoaders.java:178) ~[na:na]
    at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:521) ~[na:na]

我该如何使用Spring Boot和Spring HATEOAS 1.0？

你可以发布你完整的pom.xml文件吗？ - Sanil Khurana

从异常来看，似乎 springfox 正在使用 0.25 版本？ - erotsppa

我已经为这个问题苦苦挣扎了一个星期。如果有人能给予指点，那真是太好了。 - Neo182

只是一条注释。对于使用 Spring Boot 2.3.x + Spring Cloud Hoxton + springdoc-openapi 的人，我的完整解决依赖关系：https://gist.github.com/rekhubs/9a635927458cd5a1f243ed0536296673 - John Smith

Answer 1

今天终于解决了这个问题！我找到的解决方法是在pom中定义hateoas的版本作为一个新属性。这样你就可以覆盖父级Spring Boot项目提供的hateoas版本。

<properties>
        <...other project related version goes here as usual ..>
        <spring-hateoas.version>1.0.1.RELEASE</spring-hateoas.version>
</properties>```

Answer 2

关于从0.×.×.RELEASE升级到1.×.×.RELEASE的HATEOAS升级，我遵循了这里的指南，因为需要进行一些重构： https://spring.io/blog/2019/03/05/spring-hateoas-1-0-m1-released 我使用了Spring HATEOAS提供的migrate-to-1.0.sh脚本（here），并且通常对我们的POJO进行了以下更改：

• ResourceSupport 现在是 RepresentationModel
• Resource<T> 现在是 EntityModel<T>
• Resources<T> 现在是 CollectionModel<T>
• PagedResources<T> 现在是 PagedModel<T>
• ControllerLinkBuilder 现在是 WebMvcLinkBuilder
• Identifiable<T> 接口已被删除，不再需要
• Link.REL_SELF 现在是 IanaLinkRelations.SELF_VALUE，以此类推
