xxl-job服务化

xxl-job作为服务,之前使用都是每个服务配置信息,采用方法的形式,xxl-job作为服务的话,只需要进行配置

配置信息
## xxljob 配置
xxl:
  job:
    enabled: false
    # 执行器通讯TOKEN [选填]:非空时启用
    #    accessToken:
    # 单个地址或多个地址逗号隔开或 注册中心服务名
    adminAddress: http://127.0.0.1:8898/xxl-job-admin
    # 调度中心的 context-path:
    # jobAdminContextPath: /job-admin
    ### 执行器AppName [选填]:执行器心跳注册分组依据;为空则关闭自动注册
    appname: ${spring.application.name}
    ### 执行器注册 [选填]:优先使用该配置作为注册地址,为空时使用内嵌服务 ”IP:PORT“ 作为注册地址。
    ### 从而更灵活的支持容器类型执行器动态IP和动态映射端口问题。
    #    address:
    #    ip:
    #    port: 9999
    # 执行器运行日志文件存储磁盘路径
    #    logpath: logs/xxl-job
    # 执行器日志文件保存天数
    logRetentionDays: 180

clientClass 实现类

clientMethod 调用的方法

加参数,比如用户为张三,年龄18
,"name":"张三","age":18

JobHandler:CommonXxlJobHandler
任务参数:{"clientClass":"com.sxcoal.station.common.client.admin.JournalismAdminClient","clientMethod":"getNewsHitsTopTenList","type":1}
 

JobHandler 如何通信的呢
CommonXxlJobHandler 作为一个微服务的项目,去做了xxl-job的整合,通过反射调用,核心代码

package com.sxcoal.station.job.executor.config;

import com.alibaba.fastjson.JSONObject;
import com.sxcoal.common.utils.SpringContextUtils;
import com.xxl.job.core.context.XxlJobHelper;
import com.xxl.job.core.handler.annotation.XxlJob;
import lombok.RequiredArgsConstructor;
import lombok.extern.slf4j.Slf4j;
import org.springframework.stereotype.Component;

import java.lang.reflect.Method;

@Slf4j
@Component
@RequiredArgsConstructor
public class CommonXxlJob {

    @XxlJob("CommonXxlJobHandler")
    public void CommonXxlJobHandler() throws Exception {

        XxlJobHelper.log("通用任务执行:{}", XxlJobHelper.getJobParam());
        log.info("通用任务执行:{}", XxlJobHelper.getJobParam());
        JSONObject jsonObject = JSONObject.parseObject(XxlJobHelper.getJobParam());
        Object object = SpringContextUtils.getBean(jsonObject.getString("clientClass"));
        Method method = object.getClass().getMethod(jsonObject.getString("clientMethod"), JSONObject.class);
        log.info("通用任务执行 client 调用返回:{}", method.invoke(object, jsonObject));
    }
}
针对处理的类(DailyPriceClient内容)

ServiceNameConstants.JOURNALISM_ADMIN 代表哪个服务

package com.sxcoal.station.common.client.admin;

import com.alibaba.fastjson.JSONObject;
import com.sxcoal.common.domain.RespResult;
import com.sxcoal.common.model.mq.CommonMessageDto;
import com.sxcoal.station.common.constant.ServiceNameConstants;
import org.springframework.cloud.openfeign.FeignClient;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;

@FeignClient(
        value = ServiceNameConstants.JOURNALISM_ADMIN
        , contextId = "journalismAdmin"
        , fallbackFactory = JournalismAdminClientFallbackFactory.class
)
public interface JournalismAdminClient {

    //新闻热榜定时任务
    @PostMapping(value = "/news/getNewsHitsTopTenList")
    RespResult getNewsHitsTopTenList(@RequestBody JSONObject json);

}
 异常收集(方法和内容一样,做异常处理)
package com.sxcoal.coalresource.common.client.fallback.admin;

import com.sxcoal.coalresource.common.client.admin.CombinationPackageMiddleClient;
import com.sxcoal.common.domain.RespEnum;
import com.sxcoal.common.domain.RespResult;
import lombok.extern.slf4j.Slf4j;
import org.springframework.cloud.openfeign.FallbackFactory;
import org.springframework.stereotype.Component;

import java.util.List;

@Slf4j
@Component
public class CombinationPackageMiddleFallbackFactory implements FallbackFactory {


    @Override
    public CombinationPackageMiddleClient create(Throwable cause) {
        log.error("{} Client 调用异常: {}", "combinationPackageMiddleService", cause.getMessage(), cause);
        return new CombinationPackageMiddleClient() {
            @Override
            public RespResult> getCombinationIdListBySingleId(Long singleId) {
                return RespResult.error(RespEnum.SERVICE_FALLBACK_ERROR.getMessage(), cause.getMessage());
            }
        };
    }
}
服务内容(实现的功能)
@ApiOperation(value = "新闻浏览量前10列表")
@PostMapping(value = "/getNewsHitsTopTenList")
public RespResult getNewsHitsTopTenList(@RequestBody JSONObject jsonObject) {
    String flagStr = newsService.getNewsHitsTopTenList(jsonObject.getInteger("type"));
    if (StringUtils.equals("true", flagStr)) {
        return RespResult.ok(null, "成功");
    } else if (StringUtils.equals("false", flagStr)) {
        return RespResult.error();
    } else if (StringUtils.equals("news null", flagStr)) {
        return RespResult.error("查询新闻点击量前10的数据结果为空!");
    }
    return null;
}
