推荐答案

使用JavaScript的 功能.

Use JavaScript's window.open function.

例如

<h:form>
    <h:commandButton value="Submit" action="#{bean.submit}">
        <f:ajax render="popup" />
    </h:commandButton>

    <h:panelGroup id="popup">
        <ui:fragment rendered="#{not empty bean.url}">
            <script>window.open('#{bean.url}');</script>
        </ui:fragment>
    </h:panelGroup>
</h:form>

使用

private String url;

public void submit() {
    this.url = sendRequestToServiceAndRetrieveURL();
}

// ...
