Springmvc+Spring+Mybatis整合开发（架构搭建）
0.项目结构
Springmvc：web层
Spring：对象的容器
Mybatis：数据库持久化操作
1.导入所有需要的jar包，提供一个pom如下：
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<include>**/*.xml</include>
</includes>

</resources>
</build>
</project>
pom.xml
2.创建Mybatis核心配置文件（sqlMapConfig.xml）
主要配置实体类的别名
<?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>
<!-- 设置别名 -->
<typeAliases>
<!-- 指定扫描包，会把包内所有的类都设置别名，别名的名称就是类名，大小写不敏感 -->
<package name="com.pojo" />
</typeAliases> </configuration>
mybatis_xml
3.创建Spring核心配置文件（applicationContext.xml）
主要配置数据库的数据源（数据库连接池）；
Mybatis的工厂（创建sqlsession工厂）；
Mapper动态代理开发扫描方式（扫描Mapper）；
配置事务管理；
<?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"
xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd
http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd
http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd"> <context:property-placeholder location="classpath:db.properties"/> <!-- 数据库连接池 -->
<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的工厂 -->
<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"/>
<!-- 下面这句话相当关键，不然会找不到xml路径 -->
<property name="mapperLocations" value="classpath:mapper/*.xml"/>
</bean> <!-- Mapper动态代理开发 扫描Mapper -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<!-- 基本包 -->
<property name="basePackage" value="com.dao"/>
</bean> <!-- 注解事务 -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"/>
</bean> <!-- 开启注解 -->
<tx:annotation-driven transaction-manager="transactionManager"/> </beans>
spring_xml
4.创建Springmvc核心配置文件（springmvc.xml）
三大组件：处理器映射器+处理器适配器+视图解释器
主要扫描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"> <!-- 扫描@Controler @Service -->
<context:component-scan base-package="com"/> <!-- 处理器映射器 -->
<!-- <bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping"/> -->
<!-- 处理器适配器 -->
<!-- <bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter"/> -->
<!-- 注解驱动:处理器映射器+处理器适配器 -->
<mvc:annotation-driven conversion-service="conversionServiceFactoryBean"/> <!-- 配置Conveter转换器 转换工厂 （日期、去掉前后空格）。。 -->
<bean id="conversionServiceFactoryBean"
class="org.springframework.format.support.FormattingConversionServiceFactoryBean">
<!-- 配置 多个转换器-->
<property name="converters">
<list>
<bean class="com.conversion.DateConveter"/>
</list>
</property>
</bean> <!-- Springmvc的异常处理器 -->
<bean class="com.exception.CustomExceptionResolver"/> <!-- 上传图片配置实现类;multipartResolver这个名字固定，因为通过名字映射 -->
<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<!-- 可以设置上传图片的大小 B 5M 1*1024*1024*5-->
<property name="maxUploadSize" value="5000000"/>
</bean> <!-- SPringmvc的拦截器 -->
<mvc:interceptors>
<!-- 多个拦截器;运行时及其复杂 -->
<mvc:interceptor>
<mvc:mapping path="/**"/>
<!-- 自定义的拦截器类 -->
<bean class="com.interceptor.Interceptor1"/>
</mvc:interceptor>
<!-- <mvc:interceptor>
<mvc:mapping path="/**"/>
自定义的拦截器类
<bean class="com.interceptor.Interceptor2"/>
</mvc:interceptor> -->
</mvc:interceptors> <!-- 视图解释器 -->
<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
配置监听器读取applicationContext.xml上下文
配置前端控制器读取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监听器 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener> <!-- 处理POST提交乱码问题 -->
<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>
<!-- 默认找 /WEB-INF/[servlet的名称]-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. /* 拦截所有 jsp js png .css 真的全拦截 建议不使用
2. *.action *.do 拦截以do action 结尾的请求 肯定能使用 ERP
3. / 拦截所有 （不包括jsp) (包含.js .png.css) 强烈建议使用 前台 面向消费者 www.jd.com/search /对静态资源放行
-->
<url-pattern>*.action</url-pattern>
</servlet-mapping>
</web-app>
web.xml
6.数据库连接池（C3P0，DBCP，JDBC，DRUID）
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/数据库名?characterEncoding=utf-8
jdbc.username=账号
jdbc.password=密码
7.日志（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整合完毕
