I want to use the latest stable version 0.19.0.RELEASE Spring HATEOAS. I combine it with the latest stable version 1.2.6.RELEASE Spring Boot. In build.gradlewe find among others
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'
}
When I launch the main application, I get an exception
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:

It looks awful, but we can translate it. On the one hand, in org.springframework.boot.autoconfigure.hateoas.HypermediaAutoConfigurationof spring-boot-autoconfigure-1.2.6.RELEASE.jarwe find
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);
...
This means that two constructor arguments are Jackson2HalModule.HalHandlerInstantiatorcalled. On the other hand, Jackson2HalModule.HalHandlerInstantiatorof spring-hateoas-0.19.0.RELEASE.jarconstructors, unfortunately, there are only 3 or 4 of the argument:
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) {
...
}
I tried newer, not stable versions Spring Boot, but this will not work either. I do not want to use a lower version Spring HATEOAS, because in this case other errors occur.
