Java @RepositoryRestController带有RepositoryRestMVCCConfiguration和AbstractAnnotationConfigDispatchers ServletInitializer的自定义控制器

我试图实现自定义控制器来处理自定义存储库中定义的方法，以便能够通过REST（根据）使用此方法公开资源

以下是配置和其他相关代码：

public class ApplicationInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {

     @Override
     protected Class<?>[] getRootConfigClasses() {
        return new Class<?>[] {ApplicationConfig.class};
     }

     @Override
     protected Class<?>[] getServletConfigClasses() {
        return new Class<?>[] {RepositoryRestMvcConfiguration.class};
     }

     @Override
     protected String[] getServletMappings() {
        return new String[]{"/api/*"};
     }

}

实验存储库：

@RepositoryRestResource
public interface ExperimentRepository extends PagingAndSortingRepository<Experiment, Long>,
    ExperimentRepositoryCustom {

    @RestResource(rel = "byName", path = "byName")
    Page<Experiment> findByNameContaining(@Param("name") String name, Pageable pageable);

}

通过基于已用存储库自动生成的链接公开的所有资源都可以访问，没有问题，但在404结束时调用GET方法（通过基于已用存储库自动生成的链接公开的资源工作正常）。我假设ExperimentController未在Spring容器中注册，或者我缺少一些关于控制器方法的附加设置。有什么建议吗

提前谢谢

您需要配置才能加载控制器。一种方法是添加一个配置类来加载控制器并将其添加到ApplicationInitializer

//PLACE THIS IN A PACKAGE WHERE YOUR CONTROLLERS ARE
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Import;
import org.springframework.data.rest.webmvc.config.RepositoryRestMvcConfiguration;

@ComponentScan
@Import(RepositoryRestMvcConfiguration.class)
public class WebConfig {
}

将您的

ApplicationInitializer

更改为

import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;

import com.spring.data.rest.test.web.WebConfig;

public class ApplicationInitializer extends
        AbstractAnnotationConfigDispatcherServletInitializer {

    @Override
    protected Class<?>[] getRootConfigClasses() {
        return new Class<?>[] { ApplicationConfig.class };
    }

    @Override
    protected Class<?>[] getServletConfigClasses() {
        return new Class<?>[] { WebConfig.class };
    }

    @Override
    protected String[] getServletMappings() {
        return new String[] { "/api/*" };
    }

}
