Spring vs Guice: The one critical difference that matters

google-logo

Spring objects are recognized based on their names It doesn’t matter whether you use XML or Java config, a Spring scope is roughly like a Map<String, Object> structure. This means that you cannot have two objects with the same name. Why is this a bad thing? If you have a large application with lots of @Configuration classes or XML files, ...

jsf-logo

With JSF, to use comboboxes, listboxes and checkboxes, you need to be aware of the javax.faces.model.SelectItem class. A SelectItem represents a single selectable option; it contains both the information needed for rendering, and the value that should be bound if the item is selected. Most of the time SelectItems are constructed with a value and a label: new SelectItem(Title.MISS, "Miss"); ...
