我想将自定义搜索端点添加到我现有的用户存储库。
我的用户存储库如下所示:
@RepositoryRestResource(collectionResourceRel="users", path="users")
public interface UserRepository extends PagingAndSortingRepository<User, Long>{
User findByUsername(String username);
}
自定义 Controller :
@BasePathAwareController
@RequestMapping("users/search")
public class CustomController implements ResourceProcessor<RepositorySearchesResource>, ResourceAssembler<User, Resource<User>> {
@Autowired
UserRepository userReposiotry;
@Autowired
private EntityLinks entityLinks;
@RequestMapping(value = "findFirst", produces = "application/json")
@ResponseBody
public ResponseEntity<Resource<User>> findFirstUser() {
Resource<User> resource = toResource(userReposiotry.findOne(1L));
return new ResponseEntity<Resource<User>>(resource, HttpStatus.OK);
}
@Override
public RepositorySearchesResource process(RepositorySearchesResource resource) {
LinkBuilder lb = entityLinks.linkFor(User.class, "username");
resource.add(new Link(lb.toString() + "/search/findFirst", "findFirst"));
return resource;
}
@Override
public Resource<User> toResource(User user) {
Resource<User> resource = new Resource<User>(user);
return resource;
}
}
这会为用户返回正确的搜索端点:
{
"_links": {
"findByUsername": {
"href": "http://localhost:8080/api/users/search/findByUsername"
},
"self": {
"href": "http://localhost:8080/api/users/search"
},
"findFirst": {
"href": "http://localhost:8080/api/users/search/findFirst",
"templated": true
}
}
}
但也适用于其他端点,例如邀请:
{
"_links": {
"findUserByInvite": {
"href": "http://localhost:8080/api/invites/search/findUserByInvite"
},
"self": {
"href": "http://localhost:8080/api/invites/search"
},
"findFirst": {
"href": "http://localhost:8080/api/invites/search/findFirst",
"templated": true
}
}
}
这怎么能仅限于用户? 谢谢
最佳答案
我假设您的邀请端点也返回一个 RepositorySearchesResource
?!每当 spring-data-rest 序列化一个 RepositorySearchesResource
时,你的 ResourceProcessor
就会被调用。如果您想要为用户和邀请提供不同的链接,您有一些选择:
- 为您的搜索端点使用不同的返回类型,以便您可以有不同的
ResourceProcessor
实现 - 在您的
ResourceProcessor
中添加更多逻辑,以区分您是在邀请还是用户用例中
