问题解决了。
final ParameterizedTypeReference<?> typeReference =
ParameterizedTypeReference.forType(
method.getGenericReturnType());
responseEntity = template.exchange(requestUrl, httpMethod, entity,
typeReference, params.getPathVariables());
我们之前的调用方式有问题， 代码如上所示。 这里处理ParameterizedTypeReference有问题。
修改为 responseEntity = template.exchange(requestUrl, httpMethod, entity,
method.getReturnType(),
params.getPathVariables());
就正常了
