所需jar包自己导入
修改web.xml,表示拦截所有请求

dispatcher-servlet.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd">
<bean class="cn.niit.Controller.HelloController" name="/hello"/>
<!-- 视图解析器 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
</beans>
hello.jsp
你好:${requestScope.hello}
HelloController
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class HelloController implements Controller {
@Override
public ModelAndView handleRequest(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws Exception {
ModelAndView hello = new ModelAndView("hello");
hello.addObject("hello", "无情");
return hello;
}
}
运行自动打开首页index.jsp,如果404找不到或者空白,运行没报错,那么试试下面的方法
image image image使用注解
记得添加命名空间
<!-- 注解扫描-->
<context:component-scan base-package="cn.niit.Controller"/>

HelloController
@Controller
public class HelloController {
@RequestMapping(value="/hello",method= RequestMethod.GET)
public String hello(Model model){
model.addAttribute("hello","世界");
// 寻找web-inf目录下的jsp/hello.jsp文件
return "hello";
}
}
