1. eureka相关异常
1.1. 异常信息
Error creating bean with name 'eurekaAutoServiceRegistration': Singleton bean creation not a1.2. 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
@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
- 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));
}
