Spring Boot REST·不能排除存储库而不排除控制器 [英] Spring Boot REST · Can't exclude a repository without excluding a controller

问题描述

我想从组件扫描中排除一个存储库。但是，我尝试过的四件事情也排除了我不想要的控制器。以下是我的：

Application.java

  @SpringBootApplication 
 @ComponentScan（com.project）
 @EntityScan（basePackages = {com.project.model}）
 @EnableJpaRepositories（com.project.repository）
 public class Application extends RepositoryRestConfigurerAdapter implements WebMvcConfigurer {
 ... 
} 
  

SaleItemController .java

  @RepositoryRestController 
公共类SaleItemController {
 ... 
} 
  

SaleItemRepository.java

  @RepositoryRestResource（collectionResourceRel =saleItem，path =saleItems，excerptProjection = SaleItemProjection.class）
 public interface SaleItemRepository extends PagingAndSortingRepository< SaleItem，Long> ;, JpaSpecificationExecutor< SaleItem> {} 
  

首次尝试：过滤应用程序 ：

  @SpringBootApplication 
 @ComponentScan（com.project）
 @EntityScan（basePackages = { com.project.model}）
 @EnableJpaRepositories（basePackages = {com.project.repository}，excludeFilters = {@ ComponentScan.Filter（type = FilterType.ASSIGNABLE_TYPE，value = SaleItemRepository.class）}） 
 public class Application extends RepositoryRestConfigurerAdapter implements WebMvcConfigurer {
 ... 
} 
  

第二次尝试： SaleItemRepository 上的条件元素：

  @RepositoryRestResource （collectionResourceRel =saleItem，path =saleItems，excerptProjection = SaleItemProjection.class）
 @ConditionalOnExpression（false）
 public interface SaleItemRepository extends PagingAndSortingRepository< SaleItem，Long> ;, JpaSpecificationExecutor< SaleItem> {} 
  

第三次尝试：

  @RepositoryRestResource（collectionResourceRel =SaleItem，path =saleItems，excerptProjection = SaleItemProjection.class）
 @NoRepositoryBean 
 public interface SaleItemRepository extends PagingAndSortingRepository< SaleItem，Long> ;, JpaSpecificationExecutor< SaleItem> {} 
  

第四次尝试：在包含过滤器优先于排除过滤器的地方阅读：

  @SpringBootApplication 
 @ComponentScan（basePackages =com.project，includeFilters = {@ ComponentScan.Filter（type = FilterType.ASSIGNABLE_TYPE， value = SaleItemController.class）}）
 @EntityScan（basePackages = {com.project.model}）
 @EnableJpaRepositories（basePackages = {com.project.repository}，excludeFilters = {@ ComponentScan.Filter（type = FilterType.ASSIGNABLE_TYPE，value = SaleItemRepository.class）}）
 public class Application extends RepositoryRestConfigurerAdapter implements WebMvcConfigurer {
 ... 
} 
  
（将 includeFilters 与 excludeFilters 抛出一个异常，因为它找不到另一个仓库）
 
 
所有的尝试都成功地排除了仓库，但也排除了我不想要的控制器。我知道存储库已被排除，因为有些内容在被排除时不会被中断，我知道控制器已被排除，因为映射在其中的端点停止工作。
 
 
 
如何仅排除存储库？
 
 
 
预先感谢。
解决方案
我终于找到了。它似乎在 SaleItemRepository 的 @RepositoryRestResource 上使用 exported = false  C $ C>。此外，我删除了 excerptProjection = SaleItemProjection.class 。
 
 
 
现在我还有其他的事情需要解决......  p> 
I want to exclude a repository from component scan. However, the four things I tried that works also exclude a controller, which I don't want. Here's what I have:

Application.java

@SpringBootApplication
@ComponentScan("com.project")
@EntityScan(basePackages = { "com.project.model" })
@EnableJpaRepositories("com.project.repository")
public class Application extends RepositoryRestConfigurerAdapter implements WebMvcConfigurer {
    ...
}


SaleItemController.java

@RepositoryRestController
public class SaleItemController {
    ...
}


SaleItemRepository.java

@RepositoryRestResource(collectionResourceRel = "saleItem", path = "saleItems", excerptProjection = SaleItemProjection.class)
public interface SaleItemRepository extends PagingAndSortingRepository<SaleItem, Long>, JpaSpecificationExecutor<SaleItem> {}
First attempt: filters on Application:
@SpringBootApplication
@ComponentScan("com.project")
@EntityScan(basePackages = { "com.project.model" })
@EnableJpaRepositories(basePackages = { "com.project.repository" }, excludeFilters={@ComponentScan.Filter(type=FilterType.ASSIGNABLE_TYPE, value=SaleItemRepository.class)})
public class Application extends RepositoryRestConfigurerAdapter implements WebMvcConfigurer {
    ...
}
Second attempt: conditional element on SaleItemRepository:
@RepositoryRestResource(collectionResourceRel = "saleItem", path = "saleItems", excerptProjection = SaleItemProjection.class)
@ConditionalOnExpression("false")
public interface SaleItemRepository extends PagingAndSortingRepository<SaleItem, Long>, JpaSpecificationExecutor<SaleItem> {}
Third attempt: 
@RepositoryRestResource(collectionResourceRel = "SaleItem", path = "saleItems", excerptProjection = SaleItemProjection.class)
@NoRepositoryBean
public interface SaleItemRepository extends PagingAndSortingRepository<SaleItem, Long>, JpaSpecificationExecutor<SaleItem> {}
Fourth attempt: read somewhere that include filters have precedence over exclude filters:
@SpringBootApplication
@ComponentScan(basePackages = "com.project", includeFilters={@ComponentScan.Filter(type=FilterType.ASSIGNABLE_TYPE, value=SaleItemController.class)})
@EntityScan(basePackages = { "com.project.model" })
@EnableJpaRepositories(basePackages = { "com.project.repository" }, excludeFilters={@ComponentScan.Filter(type=FilterType.ASSIGNABLE_TYPE, value=SaleItemRepository.class)})
public class Application extends RepositoryRestConfigurerAdapter implements WebMvcConfigurer {
    ...
}
(placing the includeFilters together with excludeFilters throws an exception because it can't find another repository)

All attempts successfully exclude the repository, but also exclude the controller, which I don't want. I know the repository has been excluded because some things don't break when it's excluded and I know the controller has been excluded because an endpoint mapped in it stops working.

How do I exclude only the repository?

Thanks in advance.
解决方案
I finally found it. It seems to be working with exported = false on SaleItemRepository's @RepositoryRestResource. Plus, I removed excerptProjection = SaleItemProjection.class.

Now I have other things to fix...
