Spring:Spring HATEOAS 0.19.0 的 Spring 引导版本?

Spring: which Spring Boot version for Spring HATEOAS 0.19.0?

我想使用Spring HATEOAS的最新稳定版0.19.0.RELEASE。我将它与 Spring Boot 的最新稳定版本 1.2.6.RELEASE 相结合。在 build.gradle 中我们发现

apply plugin: 'spring-boot'
...
dependencies {
    compile("org.springframework.boot:spring-boot-starter-web:1.2.6.RELEASE")
    compile 'org.springframework.hateoas:spring-hateoas:0.19.0.RELEASE'
}

当我启动主应用程序时,出现异常

Exception in thread "main" org.springframework.beans.factory.BeanCreationException:
Error creating bean with name 'org.springframework.boot.autoconfigure.hateoas.
HypermediaAutoConfiguration$HypermediaConfiguration$HalObjectMapperConfiguration': 
Invocation of init method failed; nested exception is java.lang.NoSuchMethodError: 
org.springframework.hateoas.hal.Jackson2HalModule$HalHandlerInstantiator.<init>
(Lorg/springframework/hateoas/RelProvider;Lorg/springframework/hateoas/hal/CurieProvider;)V
    at org.springframework.beans.factory.annotation.InitDestroyAnnotationBeanPostProcessor.postProcessBeforeInitialization(InitDestroyAnnotationBeanPostProcessor.java:136)
    ...
    at ... Application.main(Application.java:...)

这看起来很糟糕,但我们可以翻译它。一方面,在 spring-boot-autoconfigure-1.2.6.RELEASE.jarorg.springframework.boot.autoconfigure.hateoas.HypermediaAutoConfiguration 中,我们发现

public class HypermediaAutoConfiguration {
    ...
    protected static class HypermediaConfiguration {
        ...
        protected static class HalObjectMapperConfiguration {
            ...
            private void registerHalModule(ObjectMapper objectMapper) {
                ...
                Jackson2HalModule.HalHandlerInstantiator instantiator = new Jackson2HalModule.HalHandlerInstantiator(
                        HalObjectMapperConfiguration.this.relProvider,
                        HalObjectMapperConfiguration.this.curieProvider);
                ...

这意味着Jackson2HalModule.HalHandlerInstantiator的两个参数构造函数被调用。另一方面,不幸的是,在 spring-hateoas-0.19.0.RELEASE.jarJackson2HalModule.HalHandlerInstantiator 中,构造函数只有 3 或 4 个参数:

public class Jackson2HalModule extends SimpleModule {
    ...
    public static class HalHandlerInstantiator extends HandlerInstantiator {

        ...
        public HalHandlerInstantiator(RelProvider resolver, CurieProvider curieProvider,
                MessageSourceAccessor messageSource) {
            ...
        }

        public HalHandlerInstantiator(RelProvider resolver, CurieProvider curieProvider,
                MessageSourceAccessor messageSource, boolean enforceEmbeddedCollections) {
            ...
        }
        //no further constructors

我试过较新的、不稳定的 Spring Boot 版本,但这也不起作用。我不想使用较低版本的 Spring HATEOAS,因为在这种情况下会出现其他错误。

你知道有没有解决办法?

我正在使用 1.2.5.RELEASE0.19.0.RELEASE,没有任何错误。像这样升级了一些依赖项:

<properties>
        <spring-data-releasetrain.version>Gosling-RELEASE</spring-data-releasetrain.version>
        <spring-hateoas.version>0.19.0.RELEASE</spring-hateoas.version>
        <jackson.version>2.6.1</jackson.version>
</properties>

您似乎有多个版本的 spring-hateoas jar,这是我的依赖配置。

compile ("org.springframework.boot:spring-boot-starter-hateoas:1.2.6.RELEASE"){
exclude module: 'spring-hateoas'
} 
compile 'org.springframework.hateoas:spring-hateoas:0.19.0.RELEASE'

并且根据 Maven 中央 spring-boot-starter-hateoas:1.2.6.RELEASE 编译依赖项,应该与更新的 spring-hateoas 0.19.0

一起工作
