Re: [Resteasy-developers] Upgrading a client proxy from v2 to v3

[John U. <uj...@gm...>]

Ok, thanks, so I can use response.readEntity(MyPojo.class), that works.

My main problem here is that the old pattern of using ClientResponse<MyPojo>
with a generic type parameter is not only deprecated but no longer works at
all.

In the code I'm currently working on, I must check the HTTP response status
with all calls to the client, so now I have to use the interface pattern
where the method returns a (non-generic) Response type, not a POJO.

This, however changes my previous call patterns from something like

MyPojo myPojo = entitySuccessful0(client.myMethod0(…));


with

<T> T entitySuccessful0(ClientResponse<T> response) {
    if
(!Family.SUCCESSFUL.equals(response.getResponseStatus().getFamily())) {
throw …; }
    return response.getEntity();
}


to something like

MyPojo myPojo = entitySuccessful2(client.myMethod2(…), MyPojo.class));


with

<T> T entitySuccessful2(Response response, Class<T> type) {
    if (!Family.SUCCESSFUL.equals(response.getStatusInfo().getFamily())) {
throw …; }
    return response.readEntity(type);
}


This is a breaking change to MANY (ie, many 1.000s of) lines of code for
all applications that use the client.
