第一、
引入jar包
第二、
web.xml 文件修改
<servlet>
<servlet-name>springDispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!-- 配置Spring MVC 下的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>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springDispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
第三、
写controller
@Controller
@RequestMapping("/lp")
public class HelloWorld {
@RequestMapping("/he")
@ResponseBody
public Map<String,String> show(){
Map<String,String> map = new HashMap<String,String>();
map.put("1", "2");
map.put("2", "2");
map.put("3", "2");
map.put("4", "2");
map.put("5", "2");
map.put("6", "2");
return map;
}
}第四、
编写springmvc.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"
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.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">
<mvc:annotation-driven />
<!-- 注意：当springMVC-servlet.xml中使用<mvc:annotation-driven />时，如果是3.1之前已经默认注入AnnotationMethodHandlerAdapter，3.1之后默认注入RequestMappingHandlerAdapter只需加上上面提及的jar包即可! -->
<!-- 配置自动扫描的包 -->
<context:component-scan base-package="com.lium"></context:component-scan>
<!-- 配置视图解析器 如何把handler 方法返回值解析为实际的物理视图 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name = "prefix" value="/WEB-INF/views/"></property>
<property name = "suffix" value = ".jsp"></property>
</bean>
</beans>另：目录结构
