实现目标：使用springMVC前端控制器，跳转到WEB-INF的templates下面的前端页面
图示
1.目录结构
2.创建一个maven的webapp项目，创建好之后记得把index.jsp文件删除，否i则会首先跳到这个文件，我们要用前端控制器转发所有请求（如果有大佬知道怎么让他存在，又不影响，希望可以学习一下）
3.在xml里面，配置springMVC前端控制器，

<!-- 配置springMVC的前端控制器，对浏览器发送的请求进行统一处理--> < servlet > < servlet-name >springMVC</ servlet-name > < servlet-class >org.springframework.web.servlet.DispatcherServlet</ servlet-class > <!-- 配置SpringMVC配置文件的位置和名称--> < init-param > < param-name >contextConfigLocation</ param-name > < param-value >classpath:springMVC.xml</ param-value > </ init-param > <!--将前端控制器DispatcherServlet的初始化时间提前到服务器启动时--> < load-on-startup >1</ load-on-startup > </ servlet > < servlet-mapping > < servlet-name >springMVC</ servlet-name > <!--匹配除了.jsp请求路径的请求--> < url-pattern >/</ url-pattern > </ servlet-mapping > </ web-app > |
4.创建并配置springMVC.xml，记得配置一下context（开启扫描需要）

5.匹配路径

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 |
@Controller public class HelloController { //"/" -->/web-inf/templates/index.html //RequestMapping请求映射 //value可不写 @RequestMapping (value= "/" ) public String tindex(){ //返回视图名称，因为我们在视图解析器里面，配置了后缀，所以这里不用写了 return "index" ; }
@RequestMapping (value= "/target" ) public String toTarget(){ return "target" ; } } |
index.html
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
<!DOCTYPE html> < html lang = "en" xmlns:th = "http://www.thymeleaf.org" > < head > < meta charset = "UTF-8" > < title >/</ title > </ head > < body > <!--/浏览器从哪个localhost：8080开始--> <!--th:被thymeleaf解析，可从localhost：8080：项目名字开始--> <!--@{}检测到绝对路径，自动添加上下文路径--> < a th:href = "@{/target}" rel = "external nofollow" >访问目标</ a > ahhahahahah </ body > </ html > |
target.html

1 2 3 4 5 6 7 8 9 10 |
<!DOCTYPE html> < html lang = "en" xmlns:th = "http://www.thymeleaf.org" > < head > < meta charset = "UTF-8" > < title >Title</ title > </ head > < body > HELLOWORLD </ body > </ html > |
