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));
    }
}
