1、新建Maven項目html

點擊菜單欄File項，選擇New-》Project，選中Maven Project,以下圖：java

2、配置pom.xmlmysql

        </dependency>

    </dependencies>
</project>

3、配置springMVCweb

在resources文件夾下創建spring-mvc.xml,以下圖spring

具體內部配置以下：sql

<?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-3.1.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-4.0.xsd">
    <!-- 自動掃描該包，使用SpringMVC認爲包下用了@Controller註解的類是控制器,避免掃描@Service致使事務不能使用 -->
    <context:component-scan base-package = "fv">
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Service"/>
    </context:component-scan>

    <!--避免IE執行AJAX時，返回JSON出現下載文件 -->
    <bean id = "mappingJacksonHttpMessageConverter"
          class = "org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
        <property name = "supportedMediaTypes">
            <list>
                <value>text/html;charset=UTF-8</value>
            </list>
        </property>
    </bean>

    <!-- 啓動SpringMVC的註解功能，完成請求和註解POJO的映射 -->
    <bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">
        <property name="order" value="1"/>
        <property name="defaultViews">
            <list>
                <!-- JSON View -->
                <bean class="org.springframework.web.servlet.view.json.MappingJackson2JsonView">
                </bean>
            </list>
        </property>
    </bean>


    <!-- 定義跳轉的文件的先後綴 ，視圖模式配置-->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <!-- 自動給後面action的方法return的字符串加上前綴和後綴，變成一個 可用的url地址 -->
        <property name="prefix" value="/WEB-INF/page/" />
        <property name="suffix" value=".jsp" />
        <!-- <property name="viewClass" value="org.springframework.web.servlet.view.InternalResourceView"/>   -->
    </bean>
    
    <!-- 文件上傳 -->
    <!-- <bean id="multipartResolver"  class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
        <property name="maxUploadSize" value="102400000"></property>
    </bean> -->
   <!-- <mvc:interceptors>
        <mvc:interceptor>
            <mvc:mapping path="/mvc/**"/>
            <bean class="test.SpringMVC.Interceptor.MyInterceptor"></bean>
        </mvc:interceptor>        
    </mvc:interceptors> -->
    <!-- 添加後能夠顯示welcome-file界面 -->
    <mvc:default-servlet-handler/>

    <!-- 啓動註解 -->
    <mvc:annotation-driven />
</beans>

4、整合mybatis數據庫

在resource文件夾下創建spring-mybatis.xml文件夾，配置內容以下：express

<?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:tx="http://www.springframework.org/schema/tx"
       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/tx
                        http://www.springframework.org/schema/tx/spring-tx.xsd">
    <!-- 自動掃描 -->
    <context:component-scan base-package="fv">
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

    <!-- 引入數據庫配置文件 -->
    <bean id = "propertyConfigurer"
          class = "org.springframework.beans.factory.config.PreferencesPlaceholderConfigurer">
        <property name = "location" value="classpath:jdbc.properties" />
    </bean>
    <!-- 鏈接池 -->
    <bean id = "dataSource" class = "org.apache.commons.dbcp.BasicDataSource"
          destroy-method = "close">
        <property name="driverClassName" value="${jdbc.driver}" />
        <property name="url" value="${jdbc.url}" />
        <property name="username" value="${jdbc.username}" />
        <property name="password" value="${jdbc.password}" />
        <!-- 初始化鏈接大小 -->
        <property name="initialSize" value="${jdbc.initialSize}" />
        <!-- 鏈接池最大數量 -->
        <property name="maxActive" value="${jdbc.maxActive}"/>
        <!-- 鏈接池最大空閒 -->
        <property name="maxIdle" value="${jdbc.maxIdle}" />
        <!-- 鏈接池最小空閒 -->
        <property name="minIdle" value="${jdbc.minIdle}" />
        <!-- 獲取鏈接最大等待時間 -->
        <property name="maxWait" value="${jdbc.maxWait}" />
    </bean>

    <!-- 結合Spring和Mybatis -->
    <bean id = "sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <!-- 自動掃描mapping.xml文件 -->
        <property name = "mapperLocations" value="classpath:fv/mapping/*.xml" />
    </bean>

    <!-- DAO接口所在包名，Spring會自動查找其下的類 -->
    <bean class = "org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name = "basePackage" value="fv.dao" /> 
        <property name = "sqlSessionFactoryBeanName" value = "sqlSessionFactory" />
    </bean>

    <!-- 定義事務 -->
    <bean id = "transactionManager"
          class = "org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name = "dataSource" ref = "dataSource" />
    </bean>
    <!-- 使用註解定義事務 -->
    <tx:annotation-driven transaction-manager = "transactionManager" />
</beans>

　5、配置屬性文件apache

在此總共有兩個屬性文件，一個是log4j.properties,另外一哥是數據庫鏈接文件jdbc.properties;json

log4j.properties文件內容以下：

#定義LOG輸出級別
log4j.rootLogger=INFO,Console,File
#定義日誌輸出目的地爲控制檯
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.Target=System.out
#能夠靈活地指定日誌輸出格式，下面一行是指定具體的格式
log4j.appender.Console.layout = org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n

#文件大小到達指定尺寸的時候產生一個新的文件
log4j.appender.File = org.apache.log4j.RollingFileAppender
#指定輸出目錄
log4j.appender.File.File = logs/ssm.log
#定義文件最大大小
log4j.appender.File.MaxFileSize = 10MB
# 輸出因此日誌，若是換成DEBUG表示輸出DEBUG以上級別日誌
log4j.appender.File.Threshold = ALL
log4j.appender.File.layout = org.apache.log4j.PatternLayout
log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n

jdbc.properties文件以下:

jdbc.driver=oracle.jdbc.driver.OracleDriver
jdbc.url=jdbc:oracle:thin:@192.168.1.213:1521:orcl
jdbc.username=KYYS
jdbc.password=kyys
#定義初始鏈接數
jdbc.initialSize=0
#定義最大鏈接數
jdbc.maxActive=20
#定義最大空閒
jdbc.maxIdle=20
#定義最小空閒
jdbc.minIdle=1
#定義最長等待時間
jdbc.maxWait=60000

　在webapp/WEB-INF/下web.xml文件內容以下：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
         version="3.1">
    <display-name>Archetype Created Web Application</display-name>
    <!-- Spring和Mybatis的配置文件 -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:spring-mybatis.xml</param-value>
    </context-param>

    <!-- 編碼過濾器 -->
    <filter>
        <filter-name>encodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>

        <init-param>
            <param-name>encoding</param-name>

        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>encodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
    
    <!-- configure the HiddenHttpMethodFilter,convert the post method to put or delete -->
  <!-- <filter>
      <filter-name>HiddenHttpMethodFilter</filter-name>
      <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>
  </filter>
  <filter-mapping>
      <filter-name>HiddenHttpMethodFilter</filter-name>
      <url-pattern>/*</url-pattern>
  </filter-mapping> -->

    <!-- Spring監聽器 -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <!-- 防止Spring內存溢出監聽器 -->
    <listener>
        <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
    </listener>

    <!-- Spring MVC servlet -->
    <servlet>
        <servlet-name>SpringMVC</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>
        <!-- 容器在啓動時就加載這個servlet -->
        <load-on-startup>1</load-on-startup>
        <async-supported>true</async-supported>
    </servlet>
    <servlet-mapping>
        <servlet-name>SpringMVC</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

   <!--  設置默認首頁 -->
    <welcome-file-list>
        <welcome-file>/index.jsp</welcome-file>
    </welcome-file-list> 
   
</web-app>

6、程序內容

程序目錄結構以下如：

index.jsp頁面內容：

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
測試框架<a href="test/index"  method ="POST">登陸</a>
    <form action= "test/indexPost" method ="POST">        
           <input type= "submit" value ="測試登陸"/>
     </form >
     <form action= "home/gohome" >   
           <input type= "text" id="id" name="id" value ="0"/>     
           <input type= "submit" value ="測試登陸"/>
     </form >
     <form action= "home/index" >      
           <input type= "submit" value ="測試登陸"/>
     </form >
</body>
</html>
