The specific use of this annotation, in the programming life of the blog has been written in more detail and in place, attach links:http://blog.csdn.net/li_xiao_ming/article/details/8349115In this to express gratitude to the programming life, learned a lot, a little bit less clear, small do supplementary explanation, mainly on the article mentioned:2. @ModelAttribute annotate the parameters of a Method-(2) from the form form or URL parameter (in fact,

A simple example of how to use spring annotations for caching configurations (EHCache and Oscache) is described earlier in this article.Spring annotation-based cache configuration--ehcache and OscacheNow how to use note caching in a web app based on annotation SPRINGMVC is simply a matter of declaring the SPRINGMVC con

I. OverviewSpring Boot Actuator is a child project of spring boot. With it, you can add some production-level services to your app without requiring special configuration. This tutorial shows the use of Eclipse + maven to build a restful app from scratch.The effect of this application is to access http://localhost:8080/fuck?name=xxx, return a JSON string, and access http://localhost:8080/metrics to see some information about the application heap.

class, run the test, pass!To this, the content of this chapter is finished, if there is no understanding of the annotations place, please look at my previous SSH2 series of three, as for MyBatis, it is too much content, if not clear also please look at the use of the guide.In the next chapter I will cover the web layer and use the annotations of spring MVC to implement the controller functionality. This is the original pineapple elephant, if you want

registration classification methods apply to all further bean containers. Because the implementation of AOP auto-proxying aBeanPostProcessor itself, whether it is BeanPostProcessors or beas, they are eligible to get the auto-proxying direct reference, so there is no way to knit in. BeanPostProcessor using callback APIs or annotations and custom implementation is a common SpringIoC container extension. RequiredAnnotationBeanPostProcessor is an example

Today, I looked at the video of the Dark Horse programmer, a small example of using spring AOP + custom annotations to implement permission control, personally feel that can be used for reference, organized out to share with you.Requirements: The service tier has methods that require different permissions to access.Implementation: Customize a privilegeinfo annotation
