标题SpringMVC如何搭建环境快速入门(Idea版)
Idea创建骨架
创建一个Maven
第二步
第三步
第四步:
一直点next到完成
配置Maven引入所要依赖的包
<!-- 版本锁定 -->
<properties>
<spring.version>5.0.2.RELEASE</spring.version>
</properties>
<dependencies>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>2.5</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>javax.servlet.jsp</groupId>
<artifactId>jsp-api</artifactId>
<version>2.0</version>
<scope>provided</scope>
</dependency>
</dependencies>
配置web.xml文件
<servlet>
<servlet-name>dispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!--加载Springmvc文件-->
<init-param>
<!--SpringMVC的核心控制器->
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springmvc.xml</param-value>
</init-param>
<!--加载项目的时候创建Servlet对象(当值为0或者大于0时，表示容器在应用启动时就加载这个servlet)-->
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
配置springmvc.xml文件
<?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/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">
<!-- 配置spring创建容器时要扫描的包 -->
<context:component-scan base-package="cn.upzy"></context:component-scan>
<!-- 配置视图解析器 -->
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<!--解析路径-->
<property name="prefix" value="/WEB-INF/pages/"></property>
<!--文件后缀名-->
<!-为什么是后缀名:当控制器返回一个名称时，路径正好是:/WEB-INF/pages/success.jsp-->
<property name="suffix" value=".jsp"></property>
</bean>
<!--配置spring开启注解mvc的支持 -->
<mvc:annotation-driven></mvc:annotation-driven>
</beans>
创建一个控制器类对象
<!--Spring注解:Controller为显示层对象-->
@Controller
public class HelloController {
<!--设置响应路径访问相对路径-->
@RequestMapping(path = "/hello")
public String sayHello(){
<!--在后台打印消息-->
System.out.println("hello StringMVC");
<!--返回一个文件名,根据文件名去/pages下找相应的文件-->
return "success";
}
}
创建一个前端文件index.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>Title</title>
</head>
<body>
<h3>入门程序</h3>
<a href="/hello">入门程序</a>
</body>
</html>
创建一个成功访问的文件success.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>Title</title>
</head>
<body>
<h3>入门成功</h3>
</body>
</html>
项目路径架构
启动Tomcat服务器
自动跳转页面(index.jsp点击超链接):
成功页面(success.jsp):
