spring mvc:内部资源视图解析器2(注解实现) @Controller/@RequestMapping
访问地址:
http://localhost:8080/guga2/hello/good
http://localhost:8080/guga2/hello/index
项目:guga2
包名:springxmlviewresolver
此实例配置文件有: web.xml, applicationContext.xml, springxmlviewresolver-servlet.xml, views.xml
web.xml

内部解析视图实例
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <bean id="hello" class="org.springframework.web.servlet.view.JstlView"> <property name="url" value="/WEB-INF/jsp/hello.jsp"/> </bean> <bean id="hello_good" class="org.springframework.web.servlet.view.JstlView"> <property name="url" value="/WEB-INF/jsp/hello_good.jsp"/> </bean> </beans>
注意此处:
<bean id="hello_good" class="org.springframework.web.servlet.view.JstlView"> <property name="url" value="/WEB-INF/jsp/hello_good.jsp"/> </bean>
id名称,跟 jsp文件名称一致,同时要跟helloController对应方法中的hello/good返回的视图名称一致.
HelloController.java
package springxmlviewresolver; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.ui.ModelMap; @Controller public class HelloController { @RequestMapping(value="/hello/index", method=RequestMethod.GET) public String printHello(ModelMap model) { model.addAttribute("message", "spring mvc framework 映射页面与请求实例!!!!!!"); return "hello"; } @RequestMapping(value="/hello/good", method=RequestMethod.GET) public String printGood(ModelMap model) { model.addAttribute("message", "spring mvc framework 映射页面与请求实例??????"); return "hello_good"; } }
jsp大同小异
