Swagger吐出xml响应而不是json

时间:2013-09-25 16:35:50

标签: spring spring-mvc swagger

我今年春天已经一周了。我正在使用Spring + maven + Jackson开发一个纯RESTful API服务。在探索一些最佳实践的过程中,我遇到了this,所以我决定使用spring mvc(和swaggerUI)作为文档。我通过thisthis教程来完成我想要的工作。一切都很顺利和花花公子,直到我意识到在点击/ api-docs之后我得到了XML响应,而不是在教程和其他地方的JSON响应。添加SwaggerUI时,这将无法正常工作。后来我发现了here,swaggerUI期待json。我总是可以回去使用没有服务器集成(https://github.com/wordnik/swagger-core/wiki/Adding-Swagger-to-your-API)的招摇,但这并不能真正满足我的需求。

以下是pom.xml的内容:

我在chrome dev http工具中尝试了GET / api-docs /,并将“Accept”标题设置为“application / json”,这很有效。这是否意味着我手动必须设置一些请求标题?我正在添加web.xml以防万一。

的web.xml:

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</servlet>

    <servlet-name>appServlet</servlet-name>
    <url-pattern>/</url-pattern>

我认为swagger不需要任何特殊的注释,所以我的java代码库保持不变。

这个问题太长了吗?请原谅,因为我是SO的新手。请编辑并建议。

控制器类:

@Api(value = "contacts", description = "contacts") // Swagger annotation
@Controller
@RequestMapping("/home")
public class HomeController {
@ResponseBody
  @RequestMapping(method=RequestMethod.GET)
  public Response select() {
    return new Response("success", "", "this is the humble abode of everything");
  }

@ResponseBody
  @RequestMapping(value="/{id}",method=RequestMethod.GET)
  public Response get(@PathVariable String id) {
    return new Response("Success", "", id);
  }
}

答案 0 :(得分:7)

Swagger-ui没有为其AJAX请求设置Accept标头。不幸的是,如果没有给出接受标头或没有给出路径扩展名(.json),swagger-springmvc会返回XML。

您可以手动为每个请求swagger-ui执行添加JSON接受标头。只需将以下JavaScript行添加到swagger-ui index.html文件中:

window.authorizations.add("Accept", 
    new ApiKeyAuthorization("Accept", "application/json", "header"));

这是我修改过的index.html文件:
