tiny4j:一个轻量级的类似Spring的实现

会点java,做点web,基本也就是spring全家桶,所以打算自己折腾一个,实现最基本最常用的一些功能。断断续续地终于完成了大部分自己想要的功能。实际项目中使用或许还不太现实,不过也提供了一个去了解框架实现的一个简单的版本,也让大家有动力有思路自己去实现一个,源码请戳github

IOC

IOC很大程度借鉴了Spring,简单的使用

ApplicationContext applicationContext = new ClassPathXmlApplicationContext("test.xml");
ServiceBean serviceBean=(ServiceBean)applicationContext.getBean("testService");
System.out.println(serviceBean);
serviceBean.service();

ServiceBean serviceBean2=(ServiceBean)applicationContext.getBean("serviceBean");
System.out.println(serviceBean2);
serviceBean2.service();

//全局的容器上下文
ApplicationContextHolder holder=applicationContext.getBean("applicationContextHolder", ApplicationContextHolder.class);
System.out.println("holder get bean : "+holder.getBean("serviceBean"));

rest

实现了许多SpringMvc里高频使用的功能和一些针对restful改进的功能
