使用LoganSquare

Question

我正在尝试使用LoganSqure解析器序列化json

我在我的java构建路径中添加了以下jar

jackson-annotations-2.5.0.jar
jackson-core-2.5.0.jar
logansquare-1.0.3.jar
logansquare-compiler-1.0.5.jar

以下是我的模特

@JsonObject
public class Image {

    /*
     * Standard field declaration.
     */
    @JsonField
    public String format;

}

但我仍然遇到以下错误

以下是我如何序列化

Image i = new Image();

        try {
            String data = LoganSquare.serialize(i);

            Log.e("Data ", data+"");
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

JSON请求非常简单我只是想创建一个示例请求

{"format":"png"}
