Spring中使用監聽模式

繼承ApplicationEvent寫event類

package com.nmrbt.oms.event;

import com.nmrbt.pojo.domain.UserProgress;
import org.springframework.context.ApplicationEvent;

public class OverOrderEvent extends ApplicationEvent {

    public OverOrderEvent(UserProgress user) {
        super(user);
    }
}

增加監聽

package com.nmrbt.oms.listener;

import com.nmrbt.feign.client.uc.TreeWaterClient;
import com.nmrbt.oms.event.OverOrderEvent;
import com.nmrbt.pojo.domain.UserProgress;
import com.nmrbt.pojo.request.oms.TreeWaterRequest;
import lombok.extern.log4j.Log4j2;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.ApplicationListener;
import org.springframework.stereotype.Component;

@Log4j2
@Component
public class TreeWaterListener implements ApplicationListener<OverOrderEvent> {

    @Autowired
    private TreeWaterClient treeWaterClient;

    @Override
    public void onApplicationEvent(OverOrderEvent overOrderEvent) {
        UserProgress userProgress = (UserProgress)overOrderEvent.getSource();
        TreeWaterRequest request = new TreeWaterRequest(
                userProgress.getOrderNo(),
                userProgress.getSinglePayAmount().intValue(),
                userProgress.getUserId());
        try {
            treeWaterClient.treeWater(request);
        }catch (Exception e){
            log.info(e.getMessage(),e);
        }
    }
}

使用

@Autowired
private ApplicationContext context;

context.publishEvent(overOrderEvent);
