使用SpringMVC写一个简单的跳转界面

1.目录

2.在pom.xml中配置依赖

                </configuration>
            </plugin>
        </plugins>
    </build>


</project>

3.在main下创建webapp->WEB-INF->web.xml(这里用的是2.5版本的web.xml)，此时springmvc.xml会报红，因为没写

代码语言：javascript复制

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
		  http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
           version="2.5">

    <servlet>
        <servlet-name>mvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <!-- 局部参数：声明配置文件位置 -->
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:springmvc.xml</param-value>
        </init-param>
        <!-- Servlet启动时刻：可选 -->
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>mvc</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

</web-app>

4.在resources下配置springmvc.xml文件

代码语言：javascript复制

<?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"
       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">

<!--    包扫描-->
    <context:component-scan base-package="controller"></context:component-scan>

<!--视图解析器-->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/"></property>
        <property name="suffix" value=".jsp"></property>
    </bean>


</beans>

5.在java下创建controller包->MyController

代码语言：javascript复制

package controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

/**
 * zt
 * 2020/10/9
 * 20:44
 */
@Controller
public class MyController {
    @RequestMapping("/hello")
    public String hello1(){
        System.out.println("开始跳转--->");
        return "hello2";
    }
}

6.在webapp下直接创建两个jsp文件（因为在这里创建可以直接访问）

hello.jsp

</head>
<body>
 这是hello界面跳转过来的另一个界面
</body>
</html>

7.运行结果
