springmvc的jar包保存在百度云盘jar目录下,本例中还有三个jackson的包,都在百度云盘jar目录下。
1.xml配置
web-app节点下增加
<!-- 配置SpringMVC前端控制器 -->
<servlet>
<servlet-name>springmvc-test</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!-- 指定SpringMVC配置文件 -->
<!-- SpringMVC的配置文件的默认路径是/WEB-INF/${servlet-name}-servlet.xml -->
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:config/springmvc.xml</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>springmvc-test</servlet-name>
<!-- 设置所有以action结尾的请求进入SpringMVC -->
<url-pattern>*.action</url-pattern>
</servlet-mapping>
2.src下增加config文件夹(xml配置路径放在config,这个自己随意,xml对应位置就行),config增加springmvc.xml增加内容
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd">
<!-- 注解驱动 -->
<mvc:annotation-driven />
<!-- 自动扫描controller -->
<context:component-scan base-package="springmvc.controller"/>
<!-- 配置试图解析器 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<!-- 配置逻辑视图的前缀 -->
<property name="prefix" value="/WEB-INF/jsp/"/>
<!-- 配置逻辑视图的后缀 -->
<property name="suffix" value=".jsp"/>
</bean>
</beans>
3.controller大概的几种写法
@Controller
@RequestMapping("itme")
public class ItemController {
/**
* http://localhost:8080/springmvc1/item/itemList.action
* @return
*/
@RequestMapping("/itemList.action")
public ModelAndView queryItemList() {
List<Item> list = new ArrayList<>();
list.add(new Item(1, "张三", 2399, new Date(), "人物1"));
list.add(new Item(2, "李四", 2399, new Date(), "人物2"));
list.add(new Item(3, "王五", 2399, new Date(), "人物3"));
ModelAndView modelAndView=new ModelAndView();
modelAndView.addObject("itemList", list);
modelAndView.setViewName("itemList");
return modelAndView;
}
/**
* http://localhost:8080/springmvc1/item/querylist.action
* @return
*/
@RequestMapping("/querylist.action")
public String querylist() {
return "itemList";
}
/**
* 返回json,注意引用jackson包,有三个
* http://localhost:8080/springmvc1/item/query.action
* @return
*/
@ResponseBody
@RequestMapping("/query.action")
public List<Item> query() {
List<Item> list = new ArrayList<>();
list.add(new Item(1, "张三", 2399, new Date(), "人物1"));
list.add(new Item(2, "李四", 2399, new Date(), "人物2"));
list.add(new Item(3, "王五", 2399, new Date(), "人物3"));
return list;
}
}
4.html就不贴了,看清楚springmvc.xml配置的视图位置就行了
