常见问题

Socket error occurred: localhost/0:0:0:0:0:0:0:1:2181: Connection refused

检查本地zookeeper有没启动，如果zookeeper在其他机器上，修改application-dev.yml

cloud:
    zookeeper:
      connect-string: ip:2181

如何关闭签名验证

• 针对某一个接口关闭签名验证 @ApiMapping(value = "alipay.story.get", ignoreValidate = true)

• 针对所有接口关闭签名验证

@Configuration
public class ZuulConfig extends AlipayZuulConfiguration {

    static {
        ...
        ApiConfig.getInstance().setIgnoreValidate(true);
        ...
    }

}

注册到eureka显示hostname，非ip

eureka:
  instance:
    prefer-ip-address: true
    instance-id: ${spring.cloud.client.ip-address}:${server.port}

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-commons</artifactId>
</dependency>

直接访问服务的swagger-ui.html ，提示access forbidden

找到微服务的OpenServiceConfig.java，重写内部类Swagger2中的swaggerAccessProtected()方法，返回false。线上请设置成true

// 开启文档
@Configuration
@EnableSwagger2
public static class Swagger2 extends SwaggerSupport {
    @Override
    protected String getDocTitle() {
        return "故事API";
    }

    @Override
    protected boolean swaggerAccessProtected() {
        return false;
    }
}
