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

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@Slf4jpublic 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@Slf4jpublic 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

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;@Componentpublic 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));    }}
