使用IDEA快速构建SpringMVC项目
构建Maven项目
创建一个空的Maven的项目 在空的Maven项目中建立一个空的Maven的模块 在创建好的模块右击添加框架支持 构建好的项目结构
示例
导入SpringMVC相关坐标
<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.12</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>5.1.9.RELEASE</version>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>2.5</version>
</dependency>
<dependency>
<groupId>javax.servlet.jsp</groupId>
<artifactId>jsp-api</artifactId>
<version>2.2</version>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
<version>1.2</version>
</dependency>
</dependencies>
配置SpringMVC核心控制器DispathcerServlet
<servlet>
<servlet-name>DispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring-mvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>DispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
创建Controller类并使用注解和视图页面
-
Controller类 和 注解配置Controller类中业务方法的映射地址
@Controller
public class ControllerTest2{
//映射访问路径
@RequestMapping("/t2")
public String index(Model model){
//Spring MVC会自动实例化一个Model对象用于向视图中传值
model.addAttribute("msg", "ControllerTest2");//返回视图位置
return "hello";
}
}
-
视图页面
<html>
<body>
<h2>Hello SpringMVC!</h2>
</body>
</html>
<html>
<head>
<title>Title</title>
</head>
<body>
<h1>${msg}</h1>
</body>
</html>
配置SpringMVC核心文件 spring-mvc.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 https://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc https://www.springframework.org/schema/mvc/spring-mvc.xsd">
<!--扫包-->
<context:component-scan base-package="com.shine"/>
<!---->
<bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"/>
<bean class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter"/>
<!--视图解析器:DispatcherServlet给他的ModelAndView-->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" id="internalResourceViewResolver">
<!--前缀-->
<property name="prefix" value="/WEB-INF/jsp/"/>
<!--后缀-->
<property name="suffix" value=".jsp"/>
</bean>
<mvc:annotation-driven />
</beans>
⑥客户端发起请求测试
特别注意
查看项目结构中是否有lib目录，没有需要手动添加目录并导入jra包
