requsetMapping可以修饰方法也可以修饰类 类定义了映射的初步信息,方法定义了具体信息【RUL】 requwstMapping(value,method,params,heads) value == URL method == POST/GET/PUT.. parmas和headers支持简单的表达式 @RequestMapping(value="/ph",params={"username","age!=10"}) public String testParamsAndHeader(){ System.out.println("success"); return "success"; } request映射表达式:(Ant风格的路径) *:匹配任意多个字符 @pathvariable映射RUL绑定的占位符 @RequestMapping("/test/{id}") public String testPathVariable(@PathVariable("id") Integer id){ System.out.println("test Variagle"+id); return "success"; } http://localhost:8080/SpringMVC1/test/33.do REST:资源表现层状态转化,最流行的互联网软件构架 Resources: @RequestMapping(value = "/testRequestParam") public String testRequestParam( @RequestParam(value = "username") String un, @RequestParam(value = "age", required = false, defaultValue = "0") int age) { System.out.println("testRequestParam, username: " + un + ", age: " + age); return "success"; } 获取请求参数,映射请求参数!!!! @CookieValue 使用POJO对象绑定请求参数 //此处有问题!!! 可以将Map和model和ModelMap类型数据作为目标方法的参数 BindingAwareModelMap Spring 支持REST风格的请求 REST风格的请求是通过将post请求做进一步封装而成,通过在表单中添加一个隐藏域,并给这些隐藏域一个特定的值,就能够将post请求转化成rest风格的请求【get put delete post】 @SessionAtributes可以放在类上边可以将数据放入其中,供多个类使用 @ModelAttribute 标记的方法会在被每个目标方法执行前被springMVC调用 fmt JSTL的国际化标签,需要在spring-mvc的配置文件中配置国际化资源文件 可以配置直接转发的页面,不需要handler的处理。 <mvc:view-Controller path="" view-name=""/> 注:在实际开发中通常都需要配置mvc:annotation-driven标签,否则 重定向:字符串中带有forward和redirectSpringMVC会对字符串特殊处理
