我想使用 Spring HATEOAS
的最新稳定版本 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
中我们发现了其他
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.jar
的org.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,在 spring-hateoas-0.19.0.RELEASE.jar
的 Jackson2HalModule.HalHandlerInstantiator
中,遗憾的是构造函数只有 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
我尝试了更新的、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发生其他错误。
您知道是否有任何解决方法吗?
最佳答案
我正在使用 1.2.5.RELEASE
和 0.19.0.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>
关于java - Spring:Spring HATEOAS 0.19.0 的哪个 Spring Boot 版本?,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/32719001/
