Camunda Rest API

客户端像调用本地方法一样调用引擎中的接口。

</dependency>

二：application.yml

server:
  port: 8081

spring:
  datasource:
    url: jdbc:mysql://localhost:3306/camunda?useUnicode=true&characterEncoding=utf8&serverTimezone=Asia/Shanghai&&nullCatalogMeansCurrent=true
    username: root
    password: root123
    driver-class-name: com.mysql.cj.jdbc.Driver

camunda:
  bpm:
    client:
      base-url: http://localhost:8080/engine-rest
      max-tasks: 1
      worker-id: springboot-camunda-client
      async-response-timeout: 20000
      lock-duration: 10000
      basic-auth:
        username: admin
        password: 123456

feign:
  client:
    config:
      processInstance.url: ${camunda.bpm.client.base-url}
      processDefinition.url: ${camunda.bpm.client.base-url}
      message.url: ${camunda.bpm.client.base-url}
      signal.url: ${camunda.bpm.client.base-url}
      execution.url: ${camunda.bpm.client.base-url}
      task.url: ${camunda.bpm.client.base-url}
      taskVariable.url: ${camunda.bpm.client.base-url}
      taskLocalVariable.url: ${camunda.bpm.client.base-url}
      taskIdentityLink.url: ${camunda.bpm.client.base-url}
      externalTask.url: ${camunda.bpm.client.base-url}
      incident.url: ${camunda.bpm.client.base-url}
      historicProcessInstance.url: ${camunda.bpm.client.base-url}
      deployment.url: ${camunda.bpm.client.base-url}

三：开启

@SpringBootApplication
@EnableCamundaRestClient
public class SprigbootCamundaClientApplication {

    public static void main(String[] args) {
        SpringApplication.run(SprigbootCamundaClientApplication.class, args);
    }
}

四：test

package com.example.client;


import org.camunda.bpm.engine.HistoryService;
import org.camunda.bpm.engine.RepositoryService;
import org.camunda.bpm.engine.RuntimeService;
import org.camunda.bpm.engine.repository.Deployment;
import org.camunda.bpm.engine.repository.ProcessDefinition;
import org.camunda.bpm.engine.runtime.ProcessInstance;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.List;

@RestController
public class RestClientTestController {
    private RuntimeService runtimeService;

    private RepositoryService repositoryService;

    private HistoryService historyService;

    public RestClientTestController(@Qualifier("remote")RuntimeService runtimeService,
                                     @Qualifier("remote")RepositoryService repositoryService,@Qualifier("remote")HistoryService historyService) {
        this.runtimeService = runtimeService;
        this.repositoryService = repositoryService;
        this.historyService = historyService;
    }

    @GetMapping("/test")
    public List<Deployment> test() {
        List<Deployment> list = repositoryService.createDeploymentQuery().list();
        return list;
    }
}
