struts2 2-rest插件:将json数据发送到PUT/POST

Question

我无法使用struts2-rest-plugin将Struts2 REST服务器发送JSON数据。

它适用于XML，但我似乎找不出正确的JSON格式来发送它。

有人有这方面的经验吗？

谢了，肖恩

更新：

抱歉我没说清楚。问题是，Struts2似乎没有映射我发送到控制器中的模型的JSON数据。

下面是代码：

主计长：

public class ClientfeatureController extends ControllerParent implements ModelDriven<Object> {
    private ClientFeatureService clientFeatureService;

    private ClientFeature clientFeature = new ClientFeature();
    private List<ClientFeature> clientFeatureList;

    //Client ID
    private String id;

    public ClientfeatureController() {
        super(ClientfeatureController.class);
    }

    @Override
    public Object getModel() {
        return (clientFeatureList != null ? clientFeatureList : clientFeature);
    }

    /**
     * @return clientFeatureList through Struts2 model-driven design
     */
    public HttpHeaders show() {
        //logic to return all client features here. this works fine..

        //todo: add ETag and lastModified information for client caching purposes
        return new DefaultHttpHeaders("show").disableCaching();
    }

    // PUT request
    public String update() {
        logger.info("client id: " + clientFeature.getClientId());
        logger.info("clientFeature updated: " + clientFeature.getFeature().getDescription());

        return "update";
    }

    public HttpHeaders create() {
        logger.info("client id: " + clientFeature.getClientId());
        logger.info("feature description: " + clientFeature.getFeature().getDescription());
        return new DefaultHttpHeaders("create");
    }

    public String getId() {
        return id;
    }

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

    public void setClientFeatureService(ClientFeatureService clientFeatureService) {
        this.clientFeatureService = clientFeatureService;
    }

    public List<ClientFeature> getClientFeatureList() {
        return clientFeatureList;
    }

    public void setClientFeatureList(List<ClientFeature> clientFeatureList) {
        this.clientFeatureList = clientFeatureList;
    }

    public ClientFeature getClientFeature() {
        return clientFeature;
    }

    public void setClientFeature(ClientFeature clientFeature) {
        this.clientFeature = clientFeature;
    }
}

这是我请求的URL：

..http://localhost:8080/coreserviceswrapper/clientfeature.json

-Method: POST或PUT (尝试了这两种方法，POST映射用于创建()，并将映射放到update()中) -Header: Content: application/json

有效载荷：

{"clientFeature":{
        "feature": {
            "id": 2,
            "enabled": true,
            "description": "description1",
            "type": "type1"
        },
        "countries": ["SG"],
        "clientId": 10}
}

当我提出请求时，Struts2中的输出将记录如下：

1356436 [http-bio-8080-exec-5] WARN  net.sf.json.JSONObject  - Tried to assign property clientFeature:java.lang.Object to bean of class com.foo.bar.entity.ClientFeature
1359043 [http-bio-8080-exec-5] INFO  com.foo.bar.rest.ClientfeatureController  - client id: null

还让我补充一下，XML请求工作得很好：

网址：..http://localhost:8080/coreserviceswrapper/clientfeature.xml方法: POST/PUT内容-类型: text/xml

有效载荷：

<com.foo.bar.entity.ClientFeature>
<clientId>100</clientId>
<feature>
<description>test</description>
</feature>
</com.foo.bar.entity.ClientFeature>

输出：

1738685 [http-bio-8080-exec-7] INFO  com.foo.bar.rest.ClientfeatureController  - client id: 100
1738685 [http-bio-8080-exec-7] INFO  com.foo.bar.rest.ClientfeatureController  - feature description: test
1738717 [http-bio-8080-exec-7] INFO  org.apache.struts2.rest.RestActionInvocation  - Executed action [/clientfeature!create!xml!200] took 1466 ms (execution: 1436 ms, result: 30 ms)

Answer 1

我遇到了这样的问题。奇怪，但通过将“clientFeature”改为“model”解决了

Answer 2

我也遇到了同样的问题，我的环境是: Structs 2.3.16.3，Jquery 1.11，Struts- rest插件症状: post json数据，rest控制器不解析json数据到模型。解决方案:由于控制器是模型驱动的，浏览器客户端只需发布Json字符串就可以了。但是，似乎您必须强制jquery更改ajax调用的conenttype。

_self.update= function(model, callback) {  
          $.ajax({  
              beforeSend: function(xhrObj){
                xhrObj.setRequestHeader("Content-Type","application/json");
                xhrObj.setRequestHeader("Accept","application/json");
            },
              type: 'PUT',  
              url: this.svrUrl+"/"+ model.id + this.extension,  
              data: JSON.stringify(model), // '{"name":"' + model.name + '"}',  
              //contentType: this.contentType,
              //dataType: this.dataType,  
              processData: false,                   
              success: callback,  
              error: function(req, status, ex) {},  
              timeout:60000  
          });  
      };  

模型数据格式为: var model = {"id":"2"，"name":"name2"，"author":"author2"，"key":"key2“}

当您使用“Content”=“application/json”放置或发布数据时，插件将使用Jsonhandler自动处理它。
