探讨Dubbo与Swagger的集成 about sayi.github.com

[Redick01]

您好，说下我这变报错的具体信息吧，是创建DubboPropertyConfig这个bean的时候报错，大概是DubboPropertyConfig注入ServletContext的时候找不到要注入的Class，我这边是使用的dubbo2.8.4，并且使用的是tomcat插件通过dubbo发布http服务。

正好需要，非常感谢作者开源

[Sayi]

@sakunon 目前还是alpha版本，欢迎共同来完善。-:)

[ZoonChen]

作者有没有讨论群？可以一起交流一下

[ZoonChen]

HttpMatch 中的 findRefMethods(Method[] interfaceMethods, String operationId,String requestMethod) 方法 Collections.sort(ret, new Comparator() {
@OverRide
public int compare(Method o1, Method o2) {
return o2.getParameterCount() - o1.getParameterCount();
}
});
getParameterCount（）方法 没有定义
可不可以提交fix一下这个问题

[Sayi]

@ZoonChen 基于JDK8开发的

[hfq-yangyang-yangyang]

能否支持springfox

[hfq-yangyang-yangyang]

用的 docker swaggerapi/swagger-ui
输入input框 http://10.10.11.180:12102/swagger-dubbo/swagger.json 点击 explore按钮。
发现一个不能跨域的问题，
加了 @crossorigin(origins = "*") 问题解决

@controller
@crossorigin(origins = "*")
@RequestMapping("${swagger.dubbo.doc:swagger-dubbo}")
@Api(hidden = true)
public class SwaggerDubboController {

[hfq-yangyang-yangyang]

跨域解决后就是下面问题

Sayi/swagger-dubbo#13

[Sayi]

swagger-dubbo V2.0.1 更新日志：

• 支持最新的dubbo注解方式(@dubbocomponentscan)的服务发现
• 修复某些情况下Swagger数据以JSON格式暴露，而不是String
• Spring boot 示例
• 跨域支持的一种解决方案
• 修复若干BUG

[Redick01]

你好，支持dubbo2.8.4吗？我这边启动报错～

[Sayi]

@Redick01 目前官方dubbo最新版本是2.6.2。你的项目应该缺少这个pom：

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.0.1</version>
</dependency>

[Redick01]

很高兴您能回复我，我在这个之前也试过添加这个依赖包，依然报错。以下是我报错的具体信息，麻烦您抽空看下～

@Redick01 你是用Main方法启动的，缺少web容器。

HTTP模拟请求需要Web容器。

[xujunhua555]

我有个疑问，我目前很多项目上都有dubbo服务，那么我现在想把这些dubbo服务都统一放到swagger-dubbo这个webapp中进行统一展现，这该如何优雅的实现

[Sayi]

@xujunhua555 我的想法是通过Zookeeper去发现这些服务，然后通过swagger-dubbo暴露API文档。

[xujunhua555]

您好！ 是的，这是个办法，但是目前你github上的代码还没实现这样的需求吧？能否加个qq探讨下呢？我qq1139273516 我也是杭州上班的 原始邮件 发件人:卅一[email protected] 收件人:Sayi/[email protected] 抄送:[email protected]; [email protected] 发送时间:2018年7月11日(周三) 09:42 主题:Re: [Sayi/sayi.github.com] 探讨Dubbo与Swagger的集成 (#15) @xujunhua555 我的想法是通过Zookeeper去发现这些服务，然后通过swagger-dubbo暴露API文档。 — You are receiving this because you were mentioned.

在使用dubbo2.5.3(公司硬性要求)和Spring boot整合时，发现ReferenceManager中从ServiceBean时，取不到，有遇到这种情况吗

[finduuu]

为什么http://localhost:8080/项目名称/swagger-dubbo/swagger.json 这个接口返回的是404，地址错了吗
这个是swagger-dubbo.properties的配置
swagger.dubbo.doc=swagger-dubbo
swagger.dubbo.http=h

swagger.dubbo.application.version = 2.0
swagger.dubbo.application.groupId = com.myhexin.yyzt
swagger.dubbo.application.artifactId = yyzt-cbas-api

#rpc or local
swagger.dubbo.cluster = rpc

swagger.dubbo.enable = true
