配置执行器

启动相关xxl-job客户端服务后，会自动注册机器地址

简单任务

    /**
     * 简单任务
     *
     * @param params
     * @return
     */
    @XxlJob(value = "demoJob")
    public ReturnT<String> demoJobHandler(String params) {
        log.info("我是 jeecg-system 服务里的定时任务 demoJob，我执行了...............................");
        return ReturnT.SUCCESS;
    }

启动任务

分片任务

    /**
     * 2、分片广播任务
     */
    @XxlJob("shardingJobHandler")
    public ReturnT<String> shardingJobHandler(String param) throws Exception {

        // 分片参数
        ShardingUtil.ShardingVO shardingVO = ShardingUtil.getShardingVo();
        log.info("分片参数：当前分片序号 = {}, 总分片数 = {}", shardingVO.getIndex(), shardingVO.getTotal());

        // 业务逻辑
        for (int i = 0; i < shardingVO.getTotal(); i++) {
            if (i == shardingVO.getIndex()) {
                log.info("第 {} 片, 命中分片开始处理", i);
            } else {
                log.info("第 {} 片, 忽略", i);
            }
        }

        return ReturnT.SUCCESS;
    }

 分片任务需要多个xxl-job客户端服务，这样才能达到并行分片处理定时任务的优势。这里我们利用idea的相关设置去启动同一个demo客户端服务；但记得启动前修改下服务端口

命令任务

    /**

        String command = param;
        int exitValue = -1;

        BufferedReader bufferedReader = null;
        try {
            // command process
            Process process = Runtime.getRuntime().exec(command);
            BufferedInputStream bufferedInputStream = new BufferedInputStream(process.getInputStream());
            bufferedReader = new BufferedReader(new InputStreamReader(bufferedInputStream));

            // command log

            }
        }

        if (exitValue == 0) {
            return IJobHandler.SUCCESS;
        } else {
            return new ReturnT<String>(IJobHandler.FAIL.getCode(), "command exit value(" + exitValue + ") is failed");
        }
    }
