Name = James' > At a glance, the differences between the two styles are listed above. Of course, they can also be mixed. Grails also supports these routing styles. Although it emphasizes that the Convention is better than the configuration, it cannot avoid precise control over the URI routing address

Ruby on rail Despite the ongoing interest in software engineering, enterprise-class development rooms still have a lot of mistrust. Why? "Can the scripting language framework also fit into enterprise applications?" "The main argument for ROR is that they lack enterprise-class services (such as distributed transactions, messages, etc.)." For many businesses, platforms without these services are not considered at all. Grail is a fast enterprise-level rapid application development tool. It is based

Grails Development platform In view technology, my favorite technology, in addition to the introduction of flash variables, is template technology. The most convenient reuse technology for the Java platform in view is include. Although tiles and so on are very powerful, but because of the cumbersome configuration, so that they as the entire project layout outside, almost no application. Include is convenient to use, but it has a natural weakness in t
