报错

Invalid deploy result code: HTTP/1.1 404 http://localhost:8068/flowable-task/process-api/app-repository/deployments?deploymentKey=testApplicationDemo1&deploymentName=%E6%B5%8B%E8%AF%95%E5%BA%94%E7%94%A8%E7%A8%8B%E5%BA%8F1

如图,发布操作时,报错,对应的rest api未找到。

.yml

pom

  <dependency>
            <groupId>org.flowable</groupId>
            <artifactId>flowable-spring-boot-starter-process-rest</artifactId>
            <version>6.4.1</version>
        </dependency>
        <dependency>
            <groupId>org.flowable</groupId>
            <artifactId>flowable-ui-modeler-rest</artifactId>
            <version>6.4.1</version>
        </dependency>
        <dependency>
            <groupId>org.flowable</groupId>
            <artifactId>flowable-ui-task-rest</artifactId>
            <version>6.4.1</version>
        </dependency>

是少引用了,还是引用粗了,还是api地址错了?

哎,找了一下午了。头大。

有熟悉的老哥吗?感激不尽。

已解决,自己写个对应路由的action。内容从源码中拷贝加修改。

@RestController
@RequestMapping(value = "/flowable-task/process-api")
public class DeploymentController {

//    @Autowired
//    protected RestResponseFactory restResponseFactory;

    @Autowired
    protected RepositoryService repositoryService;

    @Autowired(required=false)
    protected BpmnRestApiInterceptor restApiInterceptor;


    /**
     * 部署(发布) rest api publish中会调用此接口而非直接ui调用
     * @param deploymentKey
     * @param deploymentName
     * @param tenantId
     * @param request
     * @param response
     * @return
     */
    @ApiImplicitParams({
            @ApiImplicitParam(name = "file", dataType = "file", paramType = "form", required = true)
    })
    @PostMapping(value = "/app-repository/deployments", produces = "application/json", consumes = "multipart/form-data")
    public DeploymentResponse uploadDeployment(@ApiParam(name = "deploymentKey") @RequestParam(value = "deploymentKey", required = false) String deploymentKey,
                                               @ApiParam(name = "deploymentName") @RequestParam(value = "deploymentName", required = false) String deploymentName,
                                               @ApiParam(name = "tenantId") @RequestParam(value = "tenantId", required = false) String tenantId,
                                               HttpServletRequest request, HttpServletResponse response) {
