### 一、启动主程序报错 ###

**1. 异常：找不到或无法加载主类 **

错误: 找不到或无法加载主类 com.zsx.EurekaServerApplication
    原因: java.lang.ClassNotFoundException: com.zsx.EurekaServerApplication
    
    Process finished with exit code 1

**2. 背景：单个spring-cloud文件夹下多个工程，通过TortoiseGit提交到Github后，再重新从Github拉取后，使用Intellij IDEA打开spring-cloud，启动主程序报错**

**3. 通过Beyond Compare 4进行对比（Push前内容和Pull后内容），发现如下变化**

**4. 解决方法，修改spring-cloud.iml 文件，将**

修改为

### 二、熔断器仪表异常 ###

**1. 异常Unable to connect to Command Metric Stream.**

**2. 解决方法**

**2.1 方法1：添加`hystrix.stream的servlet配置到`ServletRegistrationBean**

package com.zsx.config;
    
    import com.netflix.hystrix.contrib.metrics.eventstream.HystrixMetricsStreamServlet;
    import org.springframework.boot.web.servlet.ServletRegistrationBean;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    
    @Configuration
    public class HystrixServletDefinitions {
    
        @Bean(name = "hystrixRegistrationBean")
        public ServletRegistrationBean servletRegistrationBean() {
            ServletRegistrationBean registration = new ServletRegistrationBean(
                    new HystrixMetricsStreamServlet(), "/hystrix.stream");
            registration.setName("hystrixServlet");
            registration.setLoadOnStartup(1);
            return registration;
        }
    }

**2.2 方法2：**

**2.2.1 添加依赖 **

<dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-actuator</artifactId>
            </dependency>

**2.2.2 application.yml文件添加配置**

management:
      endpoints:
        web:
          exposure:
            include: hystrix.stream
          base-path: /

**2. 异常原因**

**使用了默认的`defaultZone`**

@ConfigurationProperties(EurekaClientConfigBean.PREFIX)
    public class EurekaClientConfigBean implements EurekaClientConfig, Ordered {
        /**
    	 * Default prefix for Eureka client config properties.
    	 */
    	public static final String PREFIX = "eureka.client";
    
    	/**
    	 * Default Eureka URL.
    	 */
    	public static final String DEFAULT_URL = "http://localhost:8761" + DEFAULT_PREFIX
    			+ "/";
    
    	/**
    	 * Default availability zone if none is resolved based on region.
    	 */
    	public static final String DEFAULT_ZONE = "defaultZone";
        
        private Map<String, String> serviceUrl = new HashMap<>();
    
    	{
    		this.serviceUrl.put(DEFAULT_ZONE, DEFAULT_URL);
    	}
    
    }

**3. 解决方法**

**在application.yml文件中添加如下内容**

eureka:
      client:
        serviceUrl:
          # 覆盖默认的defaultZone
          defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/
