這個是別人翻譯的官方文檔： https://blog.csdn.net/zoollcar/article/details/117351192

這個是官方文檔： Get started with Camunda | docs.camunda.org

 

任務列表：http://localhost:8080/camunda/app/tasklist/

查看部署結果： http://localhost:8080/camunda/app/cockpit/default/#/processes

 

 

step:

抄官方文檔的：

pom：

        </dependency>

java:

public class ChargeCardWorker {
    private final static Logger LOGGER = Logger.getLogger(ChargeCardWorker.class.getName());

    public static void main(String[] args) {
        ExternalTaskClient client = ExternalTaskClient.create()
                .baseUrl("http://localhost:8080/engine-rest")
                .asyncResponseTimeout(10000) // long polling timeout
                .build();

        // subscribe to an external task topic as specified in the process
        client.subscribe("charge-card")
                .lockDuration(1000) // the default lock duration is 20 seconds, but you can override this
                .handler((externalTask, externalTaskService) -> {
                    // Put your business logic here

                    // Get a process variable
                    String item = (String) externalTask.getVariable("item");
                    Long amount = (Long) externalTask.getVariable("amount");

                    LOGGER.info("Charging credit card with an amount of '" + amount + "'€ for the item '" + item + "'...");

                    try {
                        Desktop.getDesktop().browse(new URI("https://docs.camunda.org/get-started/quick-start/complete"));
                    } catch (Exception e) {
                        e.printStackTrace();
                    }

                    // Complete the task
                    externalTaskService.complete(externalTask);
                })
                .open();
    }
}

下載這兩個東西：

 

 

打開1 里面的start.bat

使用2 的畫布畫， 要填這個： http://localhost:8080/engine-rest

 

 

 

 畫完保存並部署

再看部署結果（http://localhost:8080/camunda/app/cockpit/default/#/processes）

 

啟動流程：

tasklist里：

 

 

 

 啟動后這個金額大於1000，就要人工審批，就在task里看的到（如果下於1000，就不會出現在task里)

能看到卡在批准付款里：

 

 

問題來了：

怎么批准呢？這個按鈕置灰的，到這里不會了。待續。。。
