带有GenericType的getEntity [英] getEntity with GenericType

问题描述

尝试从REST服务获取实体.我的代码是这样的:

Trying to get an Entity from a REST service. My code is like this:

我要发送这样的对象:new GenericType<List<MyObject>>() {}

I want to send in an object like this: new GenericType<List<MyObject>>() {}

像这样的方法:

public static Object callRestWithUrl(String url, Class<?> responseObject)
            throws MetaServiceException {

        ClientResponse response = RESTConnectionUtils.callMetaService(url);

            result = response.getEntity(responseObject);

        .....

但是它会在运行时被评估为List而不是GenericType，并且会引发异常.

But it gets evaluated to List during runtime and not GenericType and an exception is thrown.

推荐答案

如何调用callRestWithUrl方法?

How do you invoke your callRestWithUrl method?

如果您的方法具有签名，则可能会更好地工作:

It could be that it would work better if your method had the signature:

public static Object callRestWithUrl(String url, GenericType<List<?>> responseObject)

然后您按以下方式调用它:

And that you then invoked it as this:

List<...> list = callRestWithUrl(new GenericType<List<MyObject>>() {});
