1.查询项目列表

代码

/**
     * 查询项目列表
     * @param pageNo 当前页
     * @param pageSize 每页显示数量
     * @param searchVal 模糊搜索值
     * @author liudz
     * @date 2021/5/7
     * @return 执行结果
     **/
    @GetMapping("/project/list")
    public Response getProjectList(@RequestParam int pageNo, @RequestParam int pageSize,
        @RequestParam(required = false) String searchVal) {
        HttpHeaders headers = new HttpHeaders();
        headers.set("token", token);
        headers.set("Content-Type", "application/json");
        HttpEntity requestEntity = new HttpEntity(headers);
        String url = "";
        if (StringUtils.isEmpty(searchVal)) {
            url = address + "/dolphinscheduler/projects/list-paging?pageNo=" + pageNo + "&pageSize=" + pageSize;
        } else {
            url = address + "/dolphinscheduler/projects/list-paging?pageNo=" + pageNo + "&pageSize=" + pageSize
                + "&searchVal=" + searchVal;
        }
        ResponseEntity<DolphinschedulerResponse> response =
            restTemplate.exchange(url, HttpMethod.GET, requestEntity, DolphinschedulerResponse.class);
        return Response.success(response.getBody().getData());
    }

2.创建项目

代码

/**
     * 创建项目
     * @param projectDto 项目参数
     * @author liudz
     * @date 2021/5/7
     * @return 执行结果
     **/
    @PostMapping("/project/creat")
    public Response creatProject(@RequestBody ProjectDto projectDto) {
        try {
            String postURL = address + "/dolphinscheduler/projects/create";
            PostMethod postMethod = new PostMethod(postURL);
            postMethod.setRequestHeader("Content-Type",
                    "application/x-www-form-urlencoded;charset=utf-8");
            postMethod.setRequestHeader("token", token);
            // 参数设置，需要注意的就是里边不能传NULL，要传空字符串
            NameValuePair[] data = {new NameValuePair("projectName", projectDto.getProjectName()),
                new NameValuePair("description", projectDto.getDescription())};
            postMethod.setRequestBody(data);
            org.apache.commons.httpclient.HttpClient httpClient = new org.apache.commons.httpclient.HttpClient();
            httpClient.executeMethod(postMethod);
            JSONObject result = JSONObject.parseObject(postMethod.getResponseBodyAsString());
            if (!result.get(DictionaryEnum.CODE.getFiledString()).equals(ZERO)) {
                return Response.error(result.getInteger("code"), result.getString("msg"));
            }
        } catch (Exception e) {
            log.info("请求异常:{}", e);
        }
        return Response.success();
    }

3.更新项目

代码

/**
     * 更新项目
     * @param projectDto 项目参数
     * @author liudz
     * @date 2021/5/7
     * @return 执行结果
     **/
    @PutMapping("/project/update")
    public Response updateProject(@RequestBody ProjectDto projectDto) {
        try {
            String postURL = address + "/dolphinscheduler/projects/update";
            PostMethod postMethod = new PostMethod(postURL);
            postMethod.setRequestHeader("Content-Type",
                    "application/x-www-form-urlencoded;charset=utf-8");
            postMethod.setRequestHeader("token", token);
            // 参数设置，需要注意的就是里边不能传NULL，要传空字符串
            NameValuePair[] data = {
                new NameValuePair("projectName", projectDto.getProjectName()),
                new NameValuePair("projectId", projectDto.getProjectId().toString()),
                new NameValuePair("description", projectDto.getDescription())};
            postMethod.setRequestBody(data);
            org.apache.commons.httpclient.HttpClient httpClient = new org.apache.commons.httpclient.HttpClient();
            httpClient.executeMethod(postMethod);
            JSONObject result = JSONObject.parseObject(postMethod.getResponseBodyAsString());
            if (!result.get(DictionaryEnum.CODE.getFiledString()).equals(ZERO)) {
                return Response.error(result.getInteger("code"), result.getString("msg"));
            }
        } catch (Exception e) {
            log.info("请求异常:{}", e);
        }
        return Response.success();
    }

4.删除项目

代码

/**
     * 删除项目
     * @param projectId 项目id
     * @author liudz
     * @date 2021/5/7
     * @return 执行结果
     **/
    @DeleteMapping("/project/delete")
    public Response deleteProject(@RequestParam String projectId) {
        HttpHeaders headers = new HttpHeaders();
        headers.set("token", token);
        headers.set("Content-Type", "application/json");
        HttpEntity requestEntity = new HttpEntity(headers);
        ResponseEntity<DolphinschedulerResponse> response = restTemplate.exchange(
                address + "/dolphinscheduler/projects/delete?projectId=" + projectId, HttpMethod.GET,
                requestEntity, DolphinschedulerResponse.class);
        if (response.getBody().getCode() != ZERO) {
            return Response.error(response.getBody().getCode(), response.getBody().getMsg());
        }
        return Response.success();
    }
