The "Interceptor" in this article is mainly about intercepting the interceptor, which is one of the challenges we often encounter when customizing interceptors. One of the things that is close to blocking is not intercepting, that is, we can

Constructors are one way we like to overload, because we encounter a variety of situations when instantiating a class, such as in some cases, instances of a series of classes might have properties of the same value, then when we instantiate the

In versions earlier than tapestry4, tapestry uses a large number of dynamic calls (most of which are called using ognl), which will inevitably cause a large loss of operation efficiency. Fortunately, the bottleneck of most web applications is to access the database rather than on the page, so it does not have a devastating impact on the promotion of tapestry. But with the development of the

Equinox uses spring MVC and hibernate as the default implementation (the database is PostgreSQL ). However, you can change the Web framework to JSF, struts, tapestry, or webwork. You can also change the persistent layer box to ibatis, JDO (jpox), spring JDBC, or OJB (). Both ant and mav

Tapestry Tapestry is an open-source servlet-based application framework that uses component object models to create dynamic and interactive web applications. Java code is completely separated from HTML. It is easy to use this framework to develop large applications, and the developed applications are easy to maintain and upgrade.
