Question

我有一个像波纹管这样的模型。

public class ColumnDtoWrapper extends JavaScriptObject{

protected ColumnDtoWrapper() {}

public final native JsArray<ColumnDto> getfields() /*-{
    return this.fields;
}-*/;

public final native void gettable() /*-{
return this.table;
}-*/;

public final native JavaScriptObject getHasMany() /*-{
    return this.hasmany;
}-*/;
}

我像

一样进行服务器调用

RequestBuilder build = new RequestBuilder(RequestBuilder.POST, URL);
    try {
        Request request = build.sendRequest(null, new RequestCallback(){
            @Override
            public void onResponseReceived(Request request, Response response) {
                if(200== response.getStatusCode()){

                    }
                }

            @Override
            public void onError(Request request, Throwable exception) {
                Window.alert("error : " + exception.getLocalizedMessage());
            }

        });
    } catch (Exception e) {
        Window.alert("try err");
    }

当我成功响应JSON字符串时。我想将该字符串转换为ColumnsDtoWrapper。

像ColumnDtoWrapper col = new ColumnDtoWrapper（responce.getText（））;

但它不起作用是否有任何好的方法将字符串转换为JavaScriptObject？

使用JsonUtils.safeEval：

ColumnDtoWrapper col = JsonUtils.safeEval(response.getText());

GWT创建JAVAscriptObject表单字符串
