Feign calls get and post records

feign Call points get and post most , Other put and delete No explanation

1、get request

The caller passes userId and size And bind the @RequestParam, The service provider will automatically resolve to userId To User Object's UserId On , analysis size To PageRequest Object's size On .
service provider ：
Parameter description ：
@PathVariable("organizationId") Long tenantId The service provider and the service caller are consistent
User user The caller does not need to pass entities , The attributes of the teleportation body can be, for example userId
PageRequest pageRequest The caller does not need to pass entities , The attributes of the teleportation body can be, for example size

    @ApiOperation(" Inquire about ")
    @GetMapping("/v1/{organizationId}/page")
    public ResponseEntity<Page<User>> page(@PathVariable("organizationId") Long tenantId, User user, PageRequest pageRequest) {
    
    	Page<User> page = PageHelper.doPageAndSort(pageRequest, () -> service.page(user));
        return Results.success(page);
    }

Service callers ：
Parameter description ：
@PathVariable("organizationId") Long tenantId The service provider and the service caller are consistent
@RequestParam("userId") Long userId Is the second parameter of the service provider User An attribute of must use @RequestParam Binding property name
@RequestParam("size") int size Is the third parameter of the service provider pageRequest An attribute of must use @RequestParam Binding property name
feign Interface

@FeignClient(
        value = "service",
        fallbackFactory = RemoteServiceFallbackFactoryImpl.class,
        path = "/v1/"
)
public interface RemoteService {
    
    @GetMapping("{organizationId}/page")
    ResponseEntity<Page<User>> page(@PathVariable("organizationId") Long tenantId,
                                      @RequestParam("userId") Long userId,
                                      @RequestParam("size") int size);
}

feign abnormal

@Slf4j
@Component
public class RemoteServiceFallbackFactoryImpl implements RemoteService{
    
    @Override
    public ResponseEntity<Page<User>> page(Long tenantId, Long userId, int size) {
    
        log.info(" Failed to get data , Call parameters :{},{}", userId, size);
        throw new CommonException(" Acquisition failure ");
    }
}

controller call

@Slf4j
@RestController()
@RequestMapping({
    "/v1/{organizationId}"})
public class TestController extends BaseController {
    
    @Autowired
    PrmRemoteService remoteService;
    @GetMapping(value = "/smy-test")
    public ResponseEntity<?> smyTest() {
    
        int size = 999;
        ResponseEntity<Page<PrLine>> page= remoteService.page(0L, 1L, size);
        return Results.success(page);
    }
}

2、post request

service provider ：
Parameter description ：
@PathVariable("organizationId") Long tenantId The service provider and the service caller are consistent
@RequestBody User user The service provider and the service caller are consistent
PageRequest pageRequest The caller does not need to pass entities , The attributes of the teleportation body can be, for example size

    @PostMapping({
    "/v1/{organizationId}/create"})
    public ResponseEntity<Page<User>> create(@PathVariable("organizationId") Long tenantId,@RequestBody User user,PageRequest pageRequest) {
    
    	Page<User> page = lineService.create(tenantId, user, pageRequest);
        return Results.success(page);
    }

Service callers ：
feign Interface ：
@PathVariable("organizationId") Long tenantId The service provider and the service caller are consistent
@RequestBody User user The service provider and the service caller are consistent
PageRequest pageRequest Is the third parameter of the service provider pageRequest An attribute of must use @RequestParam Binding property name

@FeignClient(
        value = "service",
        fallbackFactory = RemoteServiceFallbackFactoryImpl.class,
        path = "/v1/"
)
public interface RemoteService {
    
        @PostMapping("/{organizationId}/create")
    	ResponseEntity<Page<PrLine>> create(@PathVariable("organizationId") Long tenantId,
    	                                    @RequestBody User user,
    	                                    @RequestParam("size") int size);
}

feign abnormal

@Component
public class RemoteServiceFallbackFactoryImpl implements RemoteService{
    
    @Override
    public ResponseEntity<Page<User>> page(Long tenantId, User user, int size) {
    
        log.info(" The data of failure , Call parameters :{},{}", userId, size);
        throw new CommonException(" Line failed ");
    }
}

controller call

@Slf4j
@RestController()
@RequestMapping({
    "/v1/{organizationId}"})
public class TestController extends BaseController {
    
    @Autowired
    PrmRemoteService remoteService;
    @GetMapping(value = "/smy-test1")
    public ResponseEntity<?> smyTest1() {
    
        int size = 999;
        User user= new User();
        user.setUserId(888L);
        ResponseEntity<Page<PrLine>> page= prmRemoteService.create(21L,user,size);
        return Results.success(page);
    }
}

summary ：
get The formal parameters of the request caller must be annotated , The service provider is the object receiving , The caller must use @RequestParam modification , Write more than one .
post The request caller must have a @RequestBody Annotations are passed to objects and can only have one , If there are other objects to receive @RequestParam modification , Write more than one .
