SpringMVC DispatcherServlet Controller 视图注解映射

关键词由优快云通过智能技术生成

①导入SpringMVC相关坐标

<!--Spring坐标-->
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context</artifactId>
    <version>5.0.5.RELEASE</version>
</dependency>
<!--SpringMVC坐标-->
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-webmvc</artifactId>
    <version>5.0.5.RELEASE</version>
</dependency>
<!--Servlet坐标-->
<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>servlet-api</artifactId>
    <version>2.5</version>
</dependency>
<!--Jsp坐标-->
<dependency>
    <groupId>javax.servlet.jsp</groupId>
    <artifactId>jsp-api</artifactId>
    <version>2.0</version>
</dependency>

②配置SpringMVC核心控制器DispathcerServlet（在web.xml）

    <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>

③创建Controller类和视图页面

public class QuickController {
    public String quickMethod(){
        System.out.println("quickMethod running.....");
        return "index";
    }
}

</head>
<body>
<h2>Hello SpringMVC!</h2>
</body>
</html>

④使用注解配置Controller类中业务方法的映射地址

@Controller
public class QuickController {
    @RequestMapping("/quick")
    public String quickMethod(){
        System.out.println("quickMethod running.....");
        return "index.jsp";
    }
}

⑤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"
       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
">

    <context:component-scan base-package="com.text"/>

</beans>

⑥访问测试地址
