1. eureka相關異常

1.1. 異常信息

Error creating bean with name 'eurekaAutoServiceRegistration': Singleton bean creation not a

1.2. 解決

1. 上述異常我在兩處地方遇到過，一是在集成txLCN分散式服務時，用到eureka註冊的時候，需要額外添加兩個配置類

package com.zhiyis.framework.service.tx;

import com.codingapi.tx.netty.service.TxManagerHttpRequestService;
import com.lorne.core.framework.utils.http.HttpUtils;
import lombok.extern.slf4j.Slf4j;
import org.springframework.stereotype.Service;

/**
 * create by lorne on 2017/11/18
 */

@Service
@Slf4j
public class TxManagerHttpRequestServiceImpl implements TxManagerHttpRequestService{

    @Override
    public String httpGet(String url) {
        log.info("httpGet-start");
        String res = HttpUtils.get(url);
        log.info("httpGet-end");
        return res;
    }

    @Override
    public String httpPost(String url, String params) {
        log.info("httpPost-start");
        String res = HttpUtils.post(url,params);
        log.info("httpPost-end");
        return res;
    }
}

package com.zhiyis.framework.service.tx;

import com.codingapi.tx.config.service.TxManagerTxUrlService;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Service;

/**
 * create by lorne on 2017/11/18
 */
@Service
@Slf4j
public class TxManagerTxUrlServiceImpl implements TxManagerTxUrlService {


    @Value("${tm.manager.url}")
    private String url;

    @Override
    public String getTxUrl() {
        log.info("load tm.manager.url :{}", url);
        return url;
    }
}

否則也會報上述錯誤

1. 二是再junit的Test類中，用@SpringBootTest創建測試的時候，若是報上述錯誤，可通過在任意spring能掃到的位置添加一個類即可

package com.zhiyis.framework.lock;

import org.springframework.beans.BeansException;
import org.springframework.beans.factory.config.BeanDefinition;
import org.springframework.beans.factory.config.BeanFactoryPostProcessor;
import org.springframework.beans.factory.config.ConfigurableListableBeanFactory;
import org.springframework.stereotype.Component;

import java.util.Arrays;

@Component
public class FeignBeanFactoryPostProcessor implements BeanFactoryPostProcessor {

    @Override
    public void postProcessBeanFactory(ConfigurableListableBeanFactory beanFactory) throws BeansException {
        if (containsBeanDefinition(beanFactory, "feignContext", "eurekaAutoServiceRegistration")) {
            BeanDefinition bd = beanFactory.getBeanDefinition("feignContext");
            bd.setDependsOn("eurekaAutoServiceRegistration");
        }
    }

    private boolean containsBeanDefinition(ConfigurableListableBeanFactory beanFactory, String... beans) {
        return Arrays.stream(beans).allMatch(b -> beanFactory.containsBeanDefinition(b));
    }
}
