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


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;
    }
}






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[]{"/"};
    }
}
