常见问题

微服务端如何获取appId等参数

OpenContext openContext = ServiceContext.getCurrentContext().getOpenContext();
String appId = openContext.getAppId();

在其它地方获取业务参数

OpenContext openContext = ServiceContext.getCurrentContext().getOpenContext();
Story bizObject = (Story)openContext.getBizObject();



OpenContext openContext = ServiceContext.getCurrentContext().getOpenContext();
Story bizObject = openContext.getBizObject(Story.class);

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;
    }
}

调试网关出现服务不可用

打断点调试,网关出现Read Timeout

参考:https://blog.csdn.net/qq_36872046/article/details/81058045

yml添加:

ribbon:
  # https://blog.csdn.net/qq_36872046/article/details/81058045
  # 路由转发超时时间,毫秒,默认值1000,详见:RibbonClientConfiguration.DEFAULT_READ_TIMEOUT。
  # 如果微服务端 处理时间过长,会导致ribbon read超时,解决办法将这个值调大一点
  ReadTimeout: 60000
