1. eureka相关异常

1.1. 异常信息

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

1.2. 解决

1. 上述异常我在两处地方遇到过，一是在集成txLCN分布式服务时，用到eureka注册的时候，需要额外添加两个配置类

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;

    }

}

否则也会报上述错误

2. 二是再junit的Test类中，用@SpringBootTest创建测试的时候，若是报上述错误，可通过在任意spring能扫到的位置添加一个类即可

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));

    }

}
