我一直在尝试创建Jersey REST Web服务.我想从Java类接收和发出JSON对象,如下所示:

@XmlRootElement
public class Book {

    public String code;

    public HashMap<String, String> names;

}

这应该像这样转换为JSON:

{
    "code": "ABC123",
    "names": {
        "de": "Die fabelhafte Welt der Amelie",
        "fr": "Le fabuleux destin d'Amelie Poulain"
    }
}

但是我找不到标准的解决方案.每个人似乎都在实施自己的包装 解决方案.这个要求对我来说似乎是极其基本的; 我无法相信这是普遍接受的解决方案,特别是因为Jersey真的是Java中更有趣的部分之一.

我也试过升级到Jackson 1.8,它只给了我这个,这是极端虚假的JSON:

{
    "code": "ABC123",
    "names": {
        "entry": [{
            "key": "de",
            "value": "Die fabelhafte Welt der Amelie"
        },
        {
            "key": "fr",
            "value": "Le fabuleux destin d'Amelie Poulain"
        }]
    }
}

有什么建议的解决方案吗？

我正在尝试使用Jersey作为框架实现一个小的REST API,原则上代码运行正常,但是当我尝试对哈希表进行'GET'时,我收到以下错误:
