SpringMVC学习（一）：搭建SpringMVC-注解-非注解

文章参考：http://www.cnblogs.com/Sinte-Beuve/p/5730553.html

一、环境搭建：

目录结构：

引用的JAR包：

如果是Maven搭建的话pom.xml配置依赖如下：

 

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

二、代码的编写：

web.xml文件的配置：

DOCTYPE web-app PUBLIC
        "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
        "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>
    
    <welcome-file-list>
        <welcome-file>index.jspwelcome-file>
    welcome-file-list>

    
    <servlet>
        <servlet-name>springMVCservlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServletservlet-class>
        <init-param>
            
            <param-name>contextConfigLocationparam-name>
            <param-value>classpath:spring-mvc.xmlparam-value>
        init-param>
        <load-on-startup>1load-on-startup>
    servlet>
    <servlet-mapping>
        <servlet-name>springMVCservlet-name>
        <url-pattern>/url-pattern>
    servlet-mapping>

web-app>

spring-mvc.xml文件的配置：

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-3.2.xsd
                         http://www.springframework.org/schema/context
                        http://www.springframework.org/schema/context/spring-context-3.2.xsd
                        http://www.springframework.org/schema/mvc
                        http://www.springframework.org/schema/mvc/spring-mvc.xsd">
    
    <context:annotation-config/>

    
    <mvc:annotation-driven/>

    
    <context:component-scan base-package="org.yoki.edu">
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    context:component-scan>

    

    
    
    
    
    

    
    <mvc:resources mapping="/css/**" location="/statics/css/"/>
    <mvc:resources mapping="/js/**" location="/statics/js/"/>
    <mvc:resources mapping="/image/**" location="/statics/image/"/>


    
    
    <bean id="defaultViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
    <property name="prefix" value="/WEB-INF/view/"/>
    <property name="suffix" value=".jsp"/>
    bean>

    
    <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
    <property name="maxUploadSize" value="20971500"/>
    <property name="defaultEncoding" value="UTF-8"/>
    <property name="resolveLazily" value="true"/>
    bean>


    
    
    <bean id="noAnnocationController" class="org.yoki.edu.controller.NoAnnocationController">
        
    bean>

    <bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
        <property name="mappings">
            <props>
                <prop key="noAnnocation">noAnnocationControllerprop>
            props>
        property>
    bean>


beans>

配置log4j.properties：

日志文件是debug中一个必不可少的工具，因此添加了log4j日志包。配置文件如下。

#配置根Logger 后面是若干个Appender
log4j.rootLogger=DEBUG,A1,R
#log4j.rootLogger=INFO,A1,R

# ConsoleAppender 输出
log4j.appender.A1=org.apache.log4j.ConsoleAppender
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=%-d{yyyy-MM-dd HH:mm:ss,SSS} [%c]-[%p] %m%n

# File 输出 一天一个文件,输出路径可以定制,一般在根路径下
log4j.appender.R=org.apache.log4j.DailyRollingFileAppender
log4j.appender.R.File=log.txt
log4j.appender.R.MaxFileSize=500KB
log4j.appender.R.MaxBackupIndex=10
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss,SSS} [%t] [%c] [%p] - %m%n

 

 

 

Controller层AnnocationController.java文件的编写：

package org.yoki.edu.controller;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;


/**
 * Created by SunnyWen on 2017/6/3.
 */
@Controller
@RequestMapping("/annocation")
public class AnnocationController {

    //添加一个日志器
    private static final Logger logger = LoggerFactory.getLogger(AnnocationController.class);

    //映射一个action
    @RequestMapping("/index")
    public  String index(){
        //输出日志文件
        logger.info("the first jsp pages");
        //返回一个index.jsp这个视图
        return "index_annocation";
    }

}

 

Controller层NoAnnocationController.java文件的编写：

 

package org.yoki.edu.controller;


import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

/**
 * Created by SunnyWen on 2017/6/3.
 */
public class NoAnnocationController implements Controller {

    @Override
    public ModelAndView handleRequest(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws Exception {
        //返回ModelAndView
         ModelAndView modelAndView =  new ModelAndView();
        //相当 于request的setAttribut，在jsp页面中通过itemsList取数据
        modelAndView.addObject("nameString", "yoki");
        //指定视图
        modelAndView.setViewName("index_noAnnocation");
        return modelAndView;
    }
}

 

 

 

/WEB-INF/index.jsp

<html>
<body>
<h2>Hello World!h2>
body>
html>

/WEB-INF/view/index_annocation.jsp

<html>
<body>
<h2>Hello! This AnnocationController !!h2>
body>
html>

 

 /WEB-INF/view/index_noAnnocation.jsp

<html>
<body>
<h2>Hello! This noAnnocationController !!h2>
body>
html>

 

 

3、打包放入web容器中运行

 

 

 

　　

　　附：IntelliJ IDEA配置Tomcat及部署项目
