Question

我有一个Jersey webservice，生成以下JSON：

{"ConfigData":[{"@name":"Admin Component Version","@value":"version 1","@type":"String"},{"@name":"Component Version","@value":"version 1","@type":"String"}]}

从这个JAX-B对象：

@XmlRootElement(name = "ConfigData")
public class ConfigData {

    @XmlAttribute(name = "name", required = true)
    String name;

    @XmlAttribute(name = "value", required = true)
    String value;

    @XmlAttribute(name = "type", required = true)
    String type;

    @XmlAttribute(name = "groupId", required = false)
    String groupId;
    [...]
}

我正在使用以下内容运行单元测试：

    final WebResource webResource = resource();
    final ClientResponse response = webResource.path(
            VersionProviderTest.SERVICE_PATH).get(ClientResponse.class);
    String jsonResponse = response.getEntity(String.class);

    ObjectMapper mapper = new ObjectMapper();
    //Exception is thrown at the line below obviously
    ConfigData[] list = mapper.readValue(jsonResponse.getBytes(),ConfigData[].class);

为什么抛出此异常？我错过了什么？这是我第一次尝试将杰克逊用于Marshall和UnMarchall课程。似乎一切都在那里......

谢谢，

那么为什么不完全跳过杰克逊并直接从球衣中获取输出。它们显然默认不使用相同的Json格式。

    final WebResource webResource = resource();
    final ClientResponse response = webResource.path(
            VersionProviderTest.SERVICE_PATH).get(ClientResponse.class);
    ConfigData[] list = response.getEntity(ConfigData[].class);

这就像一个魅力！
