0.項目結構 html

Springmvc：web層前端

Spring：對象的容器 java

Mybatis：數據庫持久化操做 mysql

1.導入全部須要的jar包，提供一個pom以下：web

pom.xml

2.建立Mybatis核心配置文件（sqlMapConfig.xml） spring

主要配置實體類的別名sql

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
    <!-- 設置別名 -->
    <typeAliases>
        <!-- 指定掃描包，會把包內全部的類都設置別名，別名的名稱就是類名，大小寫不敏感 -->
        <package name="com.pojo" />
    </typeAliases>

</configuration>

mybatis_xml

3.建立Spring核心配置文件（applicationContext.xml）數據庫

主要配置數據庫的數據源（數據庫鏈接池）； apache

Mybatis的工廠（建立sqlsession工廠）；

Mapper動態代理開發掃描方式（掃描Mapper）；

配置事務管理；

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"

    <context:property-placeholder location="classpath:db.properties"/>
    
    <!-- 數據庫鏈接池 -->
    <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}" />
        <property name="maxActive" value="10" />
        <property name="maxIdle" value="5" />
    </bean>
    
    <!-- Mybatis的工廠 -->
    <bean id="sqlSessionFactoryBean" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <!-- 核心配置文件的位置 -->
        <property name="configLocation" value="classpath:sqlMapConfig.xml"/>
        <!-- 下面這句話至關關鍵，否則會找不到xml路徑 -->
        <property name="mapperLocations" value="classpath:mapper/*.xml"/>
    </bean>

    <!-- Mapper動態代理開發   掃描Mapper -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">

    </bean>
    
    <!-- 開啓註解 -->
    <tx:annotation-driven transaction-manager="transactionManager"/>

</beans>

spring_xml

4.建立Springmvc核心配置文件（springmvc.xml）

三大組件：處理器映射器+處理器適配器+視圖解釋器

主要掃描controller和service

<?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:p="http://www.springframework.org/schema/p"
       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-4.0.xsd
        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd">

    <!-- 掃描@Controler  @Service   -->
    <context:component-scan base-package="com"/>

    <!-- 處理器映射器 -->
    <!--         <bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping"/> -->
    <!-- 處理器適配器 -->
    <!--         <bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter"/> -->
    <!-- 註解驅動:處理器映射器+處理器適配器 -->
    <mvc:annotation-driven conversion-service="conversionServiceFactoryBean"/>

    <!-- 配置Conveter轉換器  轉換工廠 （日期、去掉先後空格）。。 -->
    <bean id="conversionServiceFactoryBean"
          class="org.springframework.format.support.FormattingConversionServiceFactoryBean">
        <!-- 配置 多個轉換器-->
        <property name="converters">
            <list>
                <bean class="com.conversion.DateConveter"/>
            </list>
        </property>
    </bean>

    <!-- Springmvc的異常處理器 -->
    <bean class="com.exception.CustomExceptionResolver"/>

    <!-- 上傳圖片配置實現類;multipartResolver這個名字固定，由於經過名字映射 -->
    <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
        <!-- 能夠設置上傳圖片的大小   B   5M  1*1024*1024*5-->
        <property name="maxUploadSize" value="5000000"/>
    </bean>

    <!-- SPringmvc的攔截器 -->
    <mvc:interceptors>
        <!-- 多個攔截器;運行時及其複雜 -->
        <mvc:interceptor>
            <mvc:mapping path="/**"/>
            <!-- 自定義的攔截器類 -->
            <bean class="com.interceptor.Interceptor1"/>
        </mvc:interceptor>
        <!--         <mvc:interceptor>
                    <mvc:mapping path="/**"/>
                    自定義的攔截器類
                    <bean class="com.interceptor.Interceptor2"/>
                </mvc:interceptor> -->
    </mvc:interceptors>

    <!-- 視圖解釋器 -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <property name="suffix" value=".jsp"/>
    </bean>

</beans>

springmvc_xml

5.Web.xml中的配置

配置監聽器讀取applicationContext.xml上下文

配置前端控制器讀取springmvc.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
         id="WebApp_ID" version="2.5">
    <display-name>springmvc_spring_mybatis</display-name>
    <welcome-file-list>
        <welcome-file>index.html</welcome-file>
    </welcome-file-list>

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
    </context-param>

    <!-- Spring監聽器 -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <!-- 處理POST提交亂碼問題 -->
    <filter>
        <filter-name>encoding</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
    </filter>

    <filter-mapping>
        <filter-name>encoding</filter-name>
        <url-pattern>*.action</url-pattern>
    </filter-mapping>

    <!-- 前端控制器 -->
    <servlet>
        <servlet-name>springmvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <!-- 默認找 /WEB-INF/[servlet的名稱]-servlet.xml -->
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:springmvc.xml</param-value>
        </init-param>
    </servlet>

    <servlet-mapping>
        <servlet-name>springmvc</servlet-name>
        <!--
            1. /*  攔截全部   jsp  js png .css  真的全攔截   建議不使用
            2. *.action *.do 攔截以do action 結尾的請求     確定能使用   ERP
            3. /  攔截全部 （不包括jsp) (包含.js .png.css)  強烈建議使用     前臺 面向消費者  www.jd.com/search   /對靜態資源放行
         -->
        <url-pattern>*.action</url-pattern>
    </servlet-mapping>
</web-app>

web.xml

6.數據庫鏈接池（C3P0，DBCP，JDBC，DRUID）

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/數據庫名?characterEncoding=utf-8
jdbc.username=帳號
jdbc.password=密碼

7.日誌（LOG4J）

# Global logging configuration
log4j.rootLogger=DEBUG, stdout
# Console output...
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] - %m%n

8.至此SSM整合完畢
