升级到 Spring Boot 1.5 - 如何重构 RepositoryRestMvcConfiguration？答案

【问题描述】：

以下代码升级到 Spring Boot 1.5 后将无法编译。显然这两种方法（configureRepositoryRestConfiguration、configureValidatingRepositoryEventListener）已从RepositoryRestMvcConfiguration 类中删除。我无法找到任何有关通过 Java 在 Spring Boot 1.5 中配置休息控制器的“正确”方式的文档。我在 Spring Boot 1.5+ 上找到的所有指南都涉及基于 XML 的配置，而我强烈更喜欢坚持使用基于 Java 的配置。如何重构此类以与 1.5 更改兼容？

@Configuration
public class CustomRepositoryRestMvcConfiguration extends RepositoryRestMvcConfiguration {

  private static final String BASE_URI = "/rest";
  @Autowired private BeforeCreateSnippetValidator beforeCreateSnippetValidator;
  @Autowired private BeforeCreateModuleValidator beforeCreateModuleValidator;

  @Override
  protected void configureRepositoryRestConfiguration(RepositoryRestConfiguration config) {
    super.configureRepositoryRestConfiguration(config);
    config.setBasePath(BASE_URI);
    config.exposeIdsFor(Snippet.class, Placement.class, Module.class, Page.class, Position.class);
  }

  @Override
  protected void configureValidatingRepositoryEventListener(ValidatingRepositoryEventListener v) {
    v.addValidator("beforeCreate", beforeCreateSnippetValidator);
    v.addValidator("beforeCreate", beforeCreateModuleValidator);
  }
}

【解决方案1】：

终于经过多次猜测，我找到了解决方案。您只需将RepositoryRestMvcConfiguration 更改为RepositoryRestConfigurerAdapter 并将@Configuration 更改为@Component。这是假设您有组件扫描设置。

@Component
public class CustomRepositoryRestMvcConfiguration extends RepositoryRestConfigurerAdapter {

  private static final String BASE_URI = "/rest";
  @Autowired private BeforeCreateSnippetValidator beforeCreateSnippetValidator;
  @Autowired private BeforeCreateModuleValidator beforeCreateModuleValidator;

  @Override
  public void configureRepositoryRestConfiguration(RepositoryRestConfiguration config) {
    super.configureRepositoryRestConfiguration(config);
    config.setBasePath(BASE_URI);
    config.exposeIdsFor(Snippet.class, Placement.class, Module.class, Page.class, Position.class);
  }

  @Override
  public void configureValidatingRepositoryEventListener(ValidatingRepositoryEventListener v) {
    v.addValidator("beforeCreate", beforeCreateSnippetValidator);
    v.addValidator("beforeCreate", beforeCreateModuleValidator);
  }
}
