pom.xml

Spring配置文件

• 首先准备一个数据库相关的配置文件application.properties，最简单的配置如下

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/demo?useSSL=false&characterEncoding=utf-8
jdbc.username=root
jdbc.password=123456

• 文件开头的命名空间

<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/s ... ing-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">

• 然后在配置文件中加载上述文件

<context:property-placeholder location="classpath:application.properties" />

• 配置数据库连接池，自行根据选取的类进行相应配置

<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
    <property name="driverClass" value="${jdbc.driver}" />
    <property name="jdbcUrl" value="${jdbc.url}" />
    <property name="user" value="${jdbc.username}" />
    <property name="password" value="${jdbc.password}" />
    <property name="acquireIncrement" value="5"></property>
    <property name="initialPoolSize" value="10"></property>
    <property name="minPoolSize" value="5"></property>
    <property name="maxPoolSize" value="20"></property>
</bean>

• 根据所选的ORM框架，配置对应的sessionFactory

<!-- hibernate的 -->
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
    <property name="dataSource">
        <ref bean="dataSource"/>
    </property>
</bean>

<!-- mybatis的 -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="configLocation" value="classpath:mappers/*.xml" />
</bean>
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
    <property name="basePackage" value="pers.corvey.dao"/>
</bean>

• 配置事务管理

<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    <property name="dataSource" ref="dataSource" />
</bean>

• 扫描包

<context:component-scan base-package="pers.corvey.service"/>

SpringMVC配置文件

• 文件头的命名空间

<?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.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd
        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd">

</beans>

• 需要扫描的类<context:component-scan base-package="pers.corvey.controller"/>

• 注解<mvc:annotation-driven />

• 视图名称解析器

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

• 静态资源处理<mvc:resources mapping="/resources/**" location="/resources/"/>

web.xml配置

• web.xml的加载顺序是：<context-param> - <listener> - <filter> - <servlet>

• <context-param>包含一个参数名和值，一般需要配置contextConfigLocation来指明applicationContext.xml的位置

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

• <session-config>用于设置HttpSession的失效时间，默认为30min，以分钟为单位，必须为整数，如果为0或负数则永不超时。

<session-config>
    <session-timeout>30</session-timeout>
</session-config>

• <filter>过滤器

<filter>
    <filter-name>encodingFilter</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>
    <init-param>
        <param-name>forceEncoding</param-name>
        <param-value>true</param-value>
    </init-param>
</filter>
<filter-mapping>
    <filter-name>encodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

• <listen>监听器

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<listener>
    <listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>
</listener>

• <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:servlet-mvc.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>springmvc</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

• <welcome-file-list>指定首页文件名称

<welcome-file-list>
    <welcome-file>/WEB-INF/content/index.jsp</welcome-file>
</welcome-file-list>

日志相关配置有待补充
