springmvc框架简单搭建

一、利用xml 配置

1.web.xml

 

<web-app version="2.4"

    xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee

    http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

 

    <display-name>Spring MVC Application</display-name>

    <servlet>

        <servlet-name>mymvc-dispatcher</servlet-name>

        <!--声明mvc控制器DispatcherServlet-->

        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

       <!--声明mvc配置文件-->

       <!--如果不配置该选项，则默认扫描 ‘servlet-name’-servlet.xml文件 ，

       以该web.xml为例，如不配置，默认访问 mymvc-dispatcher-servlet.xml-->

        <init-param>

           <param-name>contextConfigLocation</param-name>

           <param-value>WEB-INF/mymvc.xml</param-value>

       </init-param>

        <load-on-startup>1</load-on-startup>

    </servlet>

 

    <servlet-mapping>

        <servlet-name>mymvc-dispatcher</servlet-name>

        <!--请求路径-->

        <url-pattern>/</url-pattern>

    </servlet-mapping>

</web-app>

 

2.mymvc.xml配置

 

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       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-3.1.xsd
                http://www.springframework.org/schema/context
                http://www.springframework.org/schema/context/spring-context-3.1.xsd
                http://www.springframework.org/schema/mvc
                http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd" >
    <mvc:annotation-driven />
    <context:component-scan base-package="com"/>
 <import resource="myjpa.xml"/>
    <bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/page/"/>
        <property name="suffix" value=".jsp"/>
    </bean>

</beans>

二、利用java 配置

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29

package com.springapp.mvc;   import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.ComponentScan; import org.springframework.context.annotation.Configuration; import org.springframework.web.servlet.ViewResolver; import org.springframework.web.servlet.config.annotation.DefaultServletHandlerConfigurer; import org.springframework.web.servlet.config.annotation.EnableWebMvc; import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter; import org.springframework.web.servlet.view.InternalResourceViewResolver; import org.springframework.web.servlet.view.JstlView; import org.springframework.web.servlet.view.UrlBasedViewResolver;   /**  * Created by zzq on 2017/11/30.  */ @Configuration @EnableWebMvc @ComponentScan(basePackages = "com") public class MvcConfig{     @Bean     public InternalResourceViewResolver setupViewResolver() {         InternalResourceViewResolver resolver = new InternalResourceViewResolver();         resolver.setPrefix("/WEB-INF/pages/");         resolver.setSuffix(".jsp"); //        resolver.setViewClass(JstlView.class);         return resolver;     } }

       

1 2 3 4 5 6 7 8 9 10 11 12 13 14

package com.springapp.mvc;   import org.springframework.context.annotation.ComponentScan; import org.springframework.context.annotation.Configuration; import org.springframework.context.annotation.FilterType; import org.springframework.web.servlet.config.annotation.EnableWebMvc;   /**  * Created by zzq on 2017/11/30.  */ @Configuration @ComponentScan(basePackages = "com",excludeFilters = {@ComponentScan.Filter(type = FilterType.ANNOTATION,value = EnableWebMvc.class)}) public class RootConfig { }

package com.springapp.mvc;

 

import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;

 

/**

 * Created by zzq on 2017/11/30.

 */

public class SpringMvcWebIn extends AbstractAnnotationConfigDispatcherServletInitializer {

    @Override

    protected Class<?>[] getRootConfigClasses() {

        return new Class<?>[]{RootConfig.class};

    }

 

    @Override

    protected Class<?>[] getServletConfigClasses() {

        return new Class<?>[]{MvcConfig.class};

    }

 

    @Override

    protected String[] getServletMappings() {

        return new String[]{"/"};

    }

}
