Question

我遇到了Spring和Gson将我的对象发送到服务器的麻烦。我得到的结果是空的，即使它包含数据。

此代码段来自Restful Web服务：

    @RequestMapping("/summe")
    public @ResponseBody String summe(ArrayList<ServiceSettingsListItem> list) {
    return "Greeting.summe() = <" + list + ">" + list.size();   
}

我的客户：

    private static Gson gson = new GsonBuilder().create();

public static void main(String[] args) throws IOException {
    String fileContent = new String(Files.readAllBytes(new 
File("demo.json").toPath()));
    ServiceSettings serviceSettings = gson.fromJson(fileContent, 
ServiceSettings.class);
    String baseUrl = serviceSettings.getUrl();
    RestTemplate restTemplate = new RestTemplate();
    String result = restTemplate.postForObject(baseUrl, serviceSettings, String.class);
    System.out.println(result);
}

public static class ServiceSettings {

    @Override
    public String toString() {
        return "ServiceSettings [url=" + url + ", test=" + test + ", items=" 
    + items + "]";
    }

    private String url;
    private int test;
    private ArrayList<ServiceSettingsListItem> items = new ArrayList<>();

    public String getUrl() {
        return url;
    }

    public void setUrl(String url) {
        this.url = url;
    }

    public int getTest() {
        return test;
    }

    public void setTest(int test) {
        this.test = test;
    }

    public ArrayList<ServiceSettingsListItem> getItems() {
        return items;
    }

    public void setItems(ArrayList<ServiceSettingsListItem> items) {
        this.items = items;
    }

}

public static class ServiceSettingsListItem {
    private String name;
    private int value;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getValue() {
        return value;
    }

    public void setValue(int value) {
        this.value = value;
    }

}

}

这是我的JSON：

{"url":"http://localhost:8080/summe",
"test":123,
"items":[
 {"name":"name1","value":5},
 {"name":"name1","value":6}
 ]
}

我希望得到两个结果，但结果表明它是0。

而不是POST var compilation = await project.GetCompilationAsync(); //Add Module compilation.AddReferences(ModuleMetadata.CreateFromFile(@"c:\artifacts\MyLib.netmodule").GetReference()); compilationStatus = compilation.Emit(outputFolderPath + @"\Test1.dll", outputFolderPath + @"\Test1.pdb"); if (!compilationStatus.Success) { foreach (var item in compilationStatus.Diagnostics) { Console.WriteLine(item); } }对象，您需要发布它的ServiceSettings元素，因为控制器期望有效负载是一个列表。请尝试以下方法：

items

Spring RESTful Web服务POST对象
