Spring Data Rest 未映射

Question

我正在尝试使用弹簧数据休息。我已将其依赖项包含在 pom 中并定义了以下 bean，但没有为 repos 创建映射。我从哪里开始寻找问题？

@Bean
    public RepositoryRestConfigurer repositoryRestConfigurer(){

        return new RepositoryRestConfigurerAdapter(){

            @Override
            public void configureRepositoryRestConfiguration(RepositoryRestConfiguration config){
                config.setBasePath("/api");
            }
        };
    }

以下是 pom.xml

存储库

package com.pdma.dmapp.module.surveys.repo;

@Transactional("jpaTXManager")
@RepositoryRestResource(exported = true)
public interface SurveyorRepo extends CrudRepository<Surveyor, Integer> {

    Surveyor findByDeviceImeiNo1OrDeviceImeiNo2(String deviceImeiNo1, String deviceImeiNo2);
    List<Surveyor> findByDistrictDistrictId(Integer districtId);
}

Answer 1

首先，尝试通过以下方式配置Sprint Data REST：

@Configuration
public class CustomRepositoryRestConfiguration extends RepositoryRestMvcConfiguration {
            @Override
            public void configureRepositoryRestConfiguration(RepositoryRestConfiguration config){
                config.setBasePath("/api");
            }
...
}

此外，请确保您的存储库 bean 在 Spring 上下文中可用，并使用 @RepositoryRestResource 注释对其进行注释。

编辑：我认为主要问题是如何将 MVC 与 Spring Data REST 混合使用。使用RepositoryRestMvcConfiguration 而不是RepositoryRestConfigurerAdapter。您可以在官方指南here 和here 中找到有关如何设置的详细指南。

更新：对于较新版本的Spring Data REST，基本路径的设置方式不同：

@Configuration
public class RestDataConfig  extends RepositoryRestMvcConfiguration {

    @Override
    @Bean
    public BaseUri baseUri() {
        config().setBasePath("/api");
        return new BaseUri(config().getBaseUri());
    }
}

Answer 2

值得一提的是，在 Spring Data REST 3.+ 中，RepositoryRestMvcConfiguration 的 API 发生了变化，如果人们寻求版本 3+ 的答案，可以：

1. @Import RepositoryRestMvcConfiguration

   @Import( ...,
       RepositoryRestMvcConfiguration.class,
       ...)
   public class YourConfig { //snip }
   

2. 通过扩展 RepositoryRestConfigurerAdapter 并覆盖 basePath 来注册 RepositoryRestConfigurer @Bean

   @Bean
   public RepositoryRestConfigurer repositoryRestConfigurer() {
       return new RepositoryRestConfigurerAdapter() {
           @Override
           public void configureRepositoryRestConfiguration(RepositoryRestConfiguration config){
               // snip
               config.setBasePath("/data");
               // snip               
   
   }
   

值得注意的是，可以使用相同的方法来公开实体的 ID 并管理 RepositoryRestConfigurer 负责的其他功能。
