Spring Data REST：覆盖控制器上的存储库方法

有没有办法覆盖REST方法，同时仍然保留其他自动生成的Spring方法？

仔细查看文档中的示例：虽然没有明确禁止类级请求映射，但它使用方法级请求映射。我不确定这是想要的行为还是错误，但据我所知，这是使其工作的唯一方法，如此处所述。

只需将控制器更改为：

@RepositoryRestController
public class FooController {

    @Autowired
    FooService fooService;

    @RequestMapping(value = "/foo/{fooId}", method = RequestMethod.PUT)
    public void updateFoo(@PathVariable Long fooId) {
        fooService.updateProperly(fooId);
    }

    // edited after Sergey's comment
    @RequestMapping(value = "/foo/{fooId}", method = RequestMethod.PUT)
    public RequestEntity<Void> updateFoo(@PathVariable Long fooId) {
        fooService.updateProperly(fooId);

        return ResponseEntity.ok().build(); // simplest use of a ResponseEntity
    }
}

让我们想象一下我们有一个实体：Account

@Entity
public class Account implements Identifiable<Integer>, Serializable {

    private static final long serialVersionUID = -3187480027431265380L;

    @Id
    private Integer id;
    private String name;

    public Account(Integer id, String name) {
        this.id = id;
        this.name = name;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    @Override
    public Integer getId() {
        return id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

在 上公开其 CRUD 端点：AccountRepository/accounts

@RepositoryRestResource(collectionResourceRel = "accounts", path = "accounts")
public interface AccountRepository extends CrudRepository<Account, Integer> {
} 

和 覆盖默认终结点窗体 .：AccountControllerGETAccountRepository

@RepositoryRestController
public class AccountController {
    private PagedResourcesAssembler<Account> pagedAssembler;

    @Autowired
    public AccountController(PagedResourcesAssembler<Account> pagedAssembler) {
        this.pagedAssembler = pagedAssembler;
    }

    private Page<Account> getAccounts(Pageable pageRequest){
        int totalAccounts= 50;
        List<Account> accountList = IntStream.rangeClosed(1, totalAccounts)
                                             .boxed()
                                             .map( value -> new Account(value, value.toString()))
                                             .skip(pageRequest.getOffset())
                                             .limit(pageRequest.getPageSize())
                                             .collect(Collectors.toList());
        return new PageImpl(accountList, pageRequest, totalAccounts);
    }

    @RequestMapping(method= RequestMethod.GET, path="/accounts", produces = "application/hal+json")
    public ResponseEntity<Page<Account>> getAccountsHal(Pageable pageRequest, PersistentEntityResourceAssembler assembler){
        return new ResponseEntity(pagedAssembler.toResource(getAccounts(pageRequest), (ResourceAssembler) assembler), HttpStatus.OK);
    }

如果调用 ，您将获得以下使用模拟实现的输出：GET /accounts?size=5&page=0

{
  "_embedded": {
    "accounts": [
      {
        "name": "1",
        "_links": {
          "self": {
            "href": "http://localhost:8080/accounts/1"
          },
          "account": {
            "href": "http://localhost:8080/accounts/1"
          }
        }
      },
      {
        "name": "2",
        "_links": {

          }
        }
      },
      {
        "name": "4",
        "_links": {
          "self": {
            "href": "http://localhost:8080/accounts/4"
          },
          "account": {
            "href": "http://localhost:8080/accounts/4"
          }
        }
      },
      {
        "name": "5",
        "_links": {
          "self": {
            "href": "http://localhost:8080/accounts/5"
          },
          "account": {
            "href": "http://localhost:8080/accounts/5"
          }
        }
      }
    ]
  },
  "_links": {
    "first": {
      "href": "http://localhost:8080/accounts?page=0&size=5"
    },
    "self": {

    },
    "next": {
      "href": "http://localhost:8080/accounts?page=1&size=5"
    },
    "last": {
      "href": "http://localhost:8080/accounts?page=9&size=5"
    }
  },
  "page": {
    "size": 5,
    "totalElements": 50,
    "totalPages": 10,
    "number": 0
  }
}

只是为了完整性，POM可以配置以下父级和依赖项：

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.2.RELEASE</version>
