扩展RepositoryRestMvcConfiguration会破坏Jackson LocalDateTime序列化 [英] Extending RepositoryRestMvcConfiguration breaks Jackson LocalDateTime Serialisation

问题描述

我正在尝试扩展 RepositoryRestMvcConfiguration 以覆盖自定义的 uriToEntityConverter ，但这样做会导致杰克逊无法从 String 序列化/反序列化 LocalDateTime 。下面的代码显示了我的子类。

I'm attempting to extend RepositoryRestMvcConfiguration to override the uriToEntityConverter for a custom one, however doing that then causes Jackson to fail to be able to serialise/deserialise LocalDateTime from String. The code below shows my subclass.

我也尝试将 jackson-datatype-jsr310 添加到 pom 看看我是否可以强制支持，但是没有我的子类它无论如何都可以工作，所以这主要是一个死胡同。

I've also tried adding jackson-datatype-jsr310 into the pom to see if I can force support, but without my subclass it works anyway so that was mostly a dead-end.

@Configuration
@Import(RepositoryRestMvcConfiguration.class)
public class RepositoryRestMvcConfigurer extends RepositoryRestMvcConfiguration {

  @Override
  @ConfigurationProperties(prefix = "spring.data.rest")
  public RepositoryRestConfiguration config() {
    return super.config();
  }


  @Override
  protected UriToEntityConverter uriToEntityConverter(ConversionService conversionService) {
    return new OverriddenUriToEntityConverter(persistentEntities(), repositoryInvokerFactory(conversionService), repositories());
  }
}

编辑：
我已经解决了通过注释我的 LocalDateTime 属性来指定要使用的序列化器和反序列化器的问题，但这更像是一个伏都教仪式而非解决方案。

I've solved the problem by annotating my LocalDateTime properties to specify what serialiser and deserialiser to use, but that feels more like a voodoo ritual than a solution.

推荐答案

所以我最终自我解决了这个问题。要实际扩展你还需要：

So I ended up self-solving this. To actually extended that you also need:

• 扩展 RepositoryRestConfigurerAdapter


• 返回上一个类并且还实现 AutoConfigureAfter

• A class that extends RepositoryRestConfigurerAdapter
• A class that returns that previous class and also implements the annotations for AutoConfigureAfter

我基于 Spring 中的 RepositoryRestMvcAutoConfiguration 类，但是将其改为 @ConditionalOnMissingBean（RepositoryRestMvcConfiguration.class）到 @ConditionalOnBean（ExtendedRepositoryRestMvcConfiguration.class）。这允许它使用重写的函数正确配置 RestRepository 。

I based mine on the RepositoryRestMvcAutoConfiguration class actually within Spring but changed it from being @ConditionalOnMissingBean(RepositoryRestMvcConfiguration.class) to @ConditionalOnBean(ExtendedRepositoryRestMvcConfiguration.class). That allowed it to properly configure the RestRepository with my overridden functions.
