摩天轮接口封装

将摩天轮开放原生接口封装为 HTTP 接口,基于 Spring Boot + mtl-open-sdk-consumer。

执行流程

步骤1:检测并添加 Maven 依赖

检测 pom.xml 是否已引入 mtl-open-sdk-consumer,若无则添加:

<dependency>
    <groupId>com.alibaba.mtl</groupId>
    <artifactId>mtl-open-sdk-consumer</artifactId>
    <version>2.0</version>
</dependency>

步骤2:初始化 ApiClient Bean

检测项目中是否已存在 ApiClient Bean 配置,若无则在配置类中添加:

@Bean(name = "mtlClient")
public ApiClient mtlClient() throws URISyntaxException {
    return new ApiClient(
            "{clientIdentifier}",  // 需在摩天轮申请
            new URI("https://open.mtl4.alibaba-inc.com"),
            EntryToken.builder()
                    .identifier("{clientIdentifier}")
                    .token("{token}")  // 需在摩天轮申请
                    .build(),
            new ClientConfiguration());
}

注意:clientIdentifier 和 token 需在摩天轮平台申请,URI 固定为 https://open.mtl4.alibaba-inc.com。

步骤3:创建 rest 包

检测项目中是否存在 rest package,若无则创建。

步骤4:创建 MtlRestController

检测 rest 包下是否存在 MtlRestController 类,若无则创建:

@RestController
@RequestMapping("/mtl")
public class MtlRestController {

    @Autowired
    private ApiClient mtlClient;

    // 若项目存在 MtlLogProducer 日志类,还需注入:
    // @Autowired
    // private GetEnv getEnv;
}

步骤5:确认原生接口定义

必须向用户确认原生接口信息,完整定义示例:

接口路径(path):/dev/api/v1/alterSheet/detail
方法类型:GET/POST
描述:查询变更单明细
Parameters(query参数):{
  "id": "integer类型,必传"
}
RequestBody(body参数):{
  "targetReleaseId": "integer类型",
  "testers": "string类型"
}

步骤6:生成 HTTP 接口

根据原生接口定义在 MtlRestController 中创建接口方法。

GET 请求示例(原生接口:/dev/api/v1/alterSheet/detail):

@GetMapping("/api/v1/alterSheet/detail")
public Map<String, Object> getAlterSheet(@RequestParam("id") String id) {
    Map<String, Object> result = MapBuilder.of("success", true).build();
    RequestMessage request = RequestMessage.builder()
            .method(HttpMethod.GET)
            .path("/dev/api/v1/alterSheet/detail")
            .json(null)
            .parameters(MapBuilder.ofAssignType("id", id).build())
            .build();
    try {
        ResponseMessage responseMessage = mtlClient.sendRequest(request);
        if (null == responseMessage) {
            throw new RuntimeException("response is null");
        }
        result.put("data", LubanTypeUtil.toJSON(responseMessage.getJson()));
    } catch (Exception e) {
        result.put("success", false);
        result.put("msg", e.getMessage());
    }
    return result;
}

POST 请求示例(带 RequestBody):

@PostMapping("/api/v1/xxx")
public Map<String, Object> postXxx(@RequestBody Map<String, Object> body) {
    Map<String, Object> result = MapBuilder.of("success", true).build();
    RequestMessage request = RequestMessage.builder()
            .method(HttpMethod.POST)
            .path("/dev/api/v1/xxx")
            .json(LubanTypeUtil.toJSONString(body))
            .parameters(null)
            .build();
    try {
        ResponseMessage responseMessage = mtlClient.sendRequest(request);
        if (null == responseMessage) {
            throw new RuntimeException("response is null");
        }
        result.put("data", LubanTypeUtil.toJSON(responseMessage.getJson()));
    } catch (Exception e) {
        result.put("success", false);
        result.put("msg", e.getMessage());
    }
    return result;
}

关键规则

日志代码(可选)

若项目存在 MtlLogProducer 类,在 try-catch 中添加:

// 成功日志
MtlLogProducer.info(
        "/dev/api/v1/xxx",
        getEnv.curEnv().getEnv(),
        "接口描述",
        LubanTypeUtil.toJSONString(request),
        LubanTypeUtil.toJSONString(responseMessage));

// 异常日志
MtlLogProducer.error(
        "/dev/api/v1/xxx",
        getEnv.curEnv().getEnv(),
        "接口描述",
        LubanTypeUtil.toJSONString(request),
        e);
