springmvc搭建注解开发的小例子
项目搭建展示
导入jar包
1、创建视图和springmvcController.java类
@Controller //需要进行注解标识
@RequestMapping("/textspringmvc")
public class springmvcController {
@RequestMapping(value="/getways")
public String getWays() {
System.out.println("成功进入");
return "show";
}
}视图：创建名称为show.jsp。里面随便书写一句文字，用来测试
2、创建配置文件springmvc.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"
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
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd">
<!--包扫描的方式，找到controller-->
<context:component-scan base-package="controller"></context:component-scan>
<mvc:annotation-driven></mvc:annotation-driven>
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/"/>
<property name="suffix" value=".jsp"/>
</bean>
</beans>
3、搭建web.xml
//classpath: 找到配置文件springmvc.xml的路径，并且配置访问的方式<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springmvc/springmvc.xml</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
搭建好后，把项目放在Tomcat上运行，浏览器端输入
http://localhost:8080/springmvc/textspringmvc/getways
完成测试。
