.WAR 文件夹。已成功地将这些部署到本地主机

activiti应用程序- http://localhost:8080/activiti-admin/
活动管理- http://localhost:8080/活动管理/
活动休息- http://localhost:8080/activiti-rest/

到目前为止,我可以使用activiti应用程序生成BPMN文件并使用该接口启动应用程序。到现在为止,一直都还不错。

所以看看 baeldung-activiti

@GetMapping("/start-process")
public String startProcess() {
    runtimeService.startProcessInstanceByKey("my-process");
    return "Process started. Number of currently running process instances = " + runtimeService.createProcessInstanceQuery().count();
}

每次命中端点时,上面的返回一个递增的值。

我的问题是这个。

使用activiti工具(运行于本地主机:8008)如何查看流程。如何链接独立java应用程序。(正在运行)本地主机:8081)使用Activiti ui界面?

如果你有 activity-rest 已配置并正在运行。restapi是有文档记录的 here .

因此,您只需要对正确的API端点执行Web服务调用。例如,列出您需要执行 GET 请求 repository/process-definitions 终结点。

public void loadProcesses(){
    // the username and password to access the rest API (same as for UI)
    String plainCreds = "username:p@ssword";
    byte[] plainCredsBytes = plainCreds.getBytes();
    byte[] base64CredsBytes = Base64.getEncoder().encode(plainCredsBytes);
    String base64Creds = new String(base64CredsBytes);

    HttpHeaders headers = new HttpHeaders();
    headers.add("Authorization", "Basic " + base64Creds);
    RestTemplate restTemplate = new RestTemplate();
    HttpEntity<String> request = new HttpEntity<>(headers);
    ResponseEntity<String> responseAsJson = restTemplate.exchange("http://localhost:8080/activiti-rest/repository/process-definitions", HttpMethod.GET, request, String.class);
}
