Question

我在Spring中定义了一个REST服务，如下所示：

  @RequestMapping(value = "/create", method = RequestMethod.POST)
   @ResponseBody
   public ResponseEntity<String> addArticle(@RequestBody Article article){
      try{
         articleService.addArticle(article.getTitle(),
                                   article.getContent(),
                                   article.getTags(),
                                   article.getPublishStatus(),
                                   article.getCompanyId(),
                                   article.getCategory());
         return new ResponseEntity<String>(HttpStatus.OK);
      } catch (Exception e){
         e.printStackTrace();
         return new ResponseEntity<String>(e.getMessage(), HttpStatus.OK);
      }
   }

我的文章定义如下：

public class Article {

   private int id;

   private String title;

   private String content;

   private String smsContent;

   public String getSmsContent()
{
    return smsContent;
}



public void setSmsContent(String smsContent)
{
    this.smsContent = smsContent;
}


private String[] tags;

   private int companyId;

   private String category;


   public String getCategory(){
      return category;
   }



   public void setCategory(String category){
      this.category = category;
   }


   private byte publishStatus;


   public String getTitle(){
      return title;
   }


   public void setTitle(String title){
      this.title = title;
   }


   public String getContent(){
      return content;
   }


   public void setContent(String content){
      this.content = content;
   }


   public String[] getTags(){
      return tags;
   }


   public void setTags(String[] tags){
      this.tags = tags;
   }


   public int getCompanyId(){
      return companyId;
   }


   public void setCompanyId(int companyId){
      this.companyId = companyId;
   }


   public byte getPublishStatus(){
      return publishStatus;
   }


   public void setPublishStatus(byte publishStatus){
      this.publishStatus = publishStatus;
   }



   public int getId(){
      return id;
   }



   public void setId(int id){
      this.id = id;
   }



}

如何使用Angular调用此服务？我尝试了以下代码：

function createArticle(name, companyId, title, content, tags, category) {
                var request = $http({
                    method : 'POST',
                    url : '/inbound/api/article/create.json',
                    headers : {
                        'Content-Type' : 'application/x-www-form-urlencoded'
                    },
                    transformRequest : function(obj) {
                        var str = [];
                        for ( var p in obj)
                            str.push(encodeURIComponent(p) + "="
                                    + encodeURIComponent(obj[p]));
                        return str.join("&");
                    },
                    data : {
                        title : title,
                        content : content,
                        tags : tags,
                        companyId : companyId,
                        category: category
                    }
                });

我收到错误415 (Unsupported Media Type)。有什么想法吗？

Answer 1

由于您正在使用JSON，因此需要相应地设置表单和处理程序。

REST处理程序

@RequestMapping(value = "/create", method = RequestMethod.POST, consumes = "application/json")

角

headers : {
    'Content-Type' : 'application/json'
},

Answer 2

<强>第一

你有：

@RequestMapping(value = "/create", method = RequestMethod.POST)

只是/create

<强>第二

你有：

url : '/inbound/api/article/create.json',

继续删除问题所在的.json

<强>第三

请务必指明ajax事件，您发送的数据是否为JSON

在REST服务中将json对象映射到Spring对象
