Header Spring 引导 REST API 版本控制的自定义 Header 方法
Custom Header Approach for Spring Boot REST API versioning
我希望使用自定义 Headers 通过 Spring Boot 和 Swagger 实施 REST API 版本控制。我经历了很多 link 如下所示。
https://dzone.com/articles/versioning-rest-api-with-spring-boot-and-swagger
有一点很清楚,我的每个 REST 端点都必须用 Custom Header headers = {"X-API-VERSION=v1"}
.
进行注释
下面是我的示例 Rest 端点。
@ApiOperation(value = "Find Employees", nickname = "Find Employees")
@ApiResponses(value = { @ApiResponse(code = 200, message = "For Success as well as No Data found scenerio."),
@ApiResponse(code = 500, message = "Internal Server Error") })
@GetMapping(value = "/employees", headers = {"X-API-VERSION=v1"})
public ResponseEntity<List<Employee>> findEmployees() {
List<Employee> EmployeeList= employeeservice.findAllEmployees();
return new ResponseEntity<List<Employee>>(EmployeeList,HttpStatus.OK);
}
Swagger 配置changes/updates
@Configuration
@EnableSwagger2
public class SwaggerConfig{
@Bean
public Docket api() {
ParameterBuilder aParameterBuilder = new ParameterBuilder();
aParameterBuilder.name("X-API-VERSION=v1").modelRef(new ModelRef("string")).parameterType("header").required(true).build();
List<Parameter> operationParameters = new ArrayList<>();
operationParameters.add(aParameterBuilder.build());
return new Docket(DocumentationType.SWAGGER_2)
.select()
.apis(Predicates.not(RequestHandlerSelectors.basePackage("org.springframework.boot")))
.apis(RequestHandlerSelectors.basePackage("com.example"))
.paths(PathSelectors.any())
.build()
.apiInfo(apiInfo())
.useDefaultResponseMessages(false)
.globalOperationParameters(operationParameters)
.globalResponseMessage(
RequestMethod.GET,
newArrayList(new ResponseMessageBuilder().code(500).message("").build()));
}
private ApiInfo apiInfo() {
return new ApiInfoBuilder()
.title("API Management")
.description("Sample Description")
.termsOfServiceUrl("https://www.test.com")
.version("0.1")
.build();
}
}
根据这个 link: https://www.springboottutorial.com/spring-boot-versioning-for-rest-services,我必须传递值 X-API-VERSION=v1
,但是当我传递那个 /employees/v1/error
端点时,它被调用了,什么都没有留下,也没有控制器被调用。如何解决这个问题?
这就是这种方法的工作原理。
@RestController
public class TestController {
@RequestMapping(value = "/user")
public String getUserDefault() {
return "getUserDefault";
}
@RequestMapping(value = "/user", headers = {"X-API-VERSION=v1"})
public String getUserV1() {
return "getUserV1";
}
@RequestMapping(value = "/user", headers = {"X-API-VERSION=v2"})
public String getUserV2() {
return "getUserV2";
}
}
此外,您可以使用 GetMapping
而不是 RequestMapping
,让我们使用 curl
进行测试:
curl --location --request GET 'http://localhost:8080/user' --header 'X-API-VERSION: v2'
return 200 getUserV2
curl --location --request GET 'http://localhost:8080/user' --header 'X-API-VERSION: v1'
return 200 getUserV1
curl --location --request GET 'http://localhost:8080/user'
return 200 getUserDefault
