一、搭建开发环境

1.数据库环境

(1)创建一个数据库。

     create database bos character set utf8

(2)创建一个数据库用户。

     create user bos identified by ’123456’

(3)为用户授权

     grant all on bos.* to bos

(4)使用创建的用户登录MySql

     mysql –ubos –p123456

2.Web环境

(1)web.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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
	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>bos</display-name>

	<!-- 解决延迟加载问题的过滤器 -->
	<filter>
		<filter-name>openSession</filter-name>
		<filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>
	</filter>

	<filter-mapping>
		<filter-name>openSession</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>

	<!-- 指定spring配置文件 -->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:applicationContext.xml</param-value>
	</context-param>

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

	<!-- 解决post乱码 -->
	<filter>
		<filter-name>CharacterEncodingFilter</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>CharacterEncodingFilter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>

	<!-- struts2核心过滤器 -->
	<filter>
		<filter-name>struts</filter-name>
		<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
	</filter>

	<filter-mapping>
		<filter-name>struts</filter-name>
		<url-pattern>/*</url-pattern>
		<dispatcher>REQUEST</dispatcher>
		<!-- 服务器内部转发也会经过过滤器处理 -->
		<dispatcher>FORWARD</dispatcher>
	</filter-mapping>

	<welcome-file-list>
		<welcome-file>index.html</welcome-file>
		<welcome-file>index.htm</welcome-file>
		<welcome-file>index.jsp</welcome-file>
		<welcome-file>default.html</welcome-file>
		<welcome-file>default.htm</welcome-file>
		<welcome-file>default.jsp</welcome-file>
	</welcome-file-list>
</web-app>

(2)struts.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
	"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
	"http://struts.apache.org/dtds/struts-2.3.dtd">

<struts>

	<!-- 开启开发模式 -->
	<constant name="struts.devMode" value="true" />
	<package name="user" extends="struts-default">

		<!-- 需要进行权限控制的页面访问 -->
		<action name="page_*_*">
			<result type="dispatcher">/WEB-INF/pages/{1}/{2}.jsp</result>
		</action>

	</package>

</struts>

(3) 配置applicationContext.xml

     数据源、LocalSessionFactoryBean、事务管理器、组件扫描、支持Spring注解、事务注解支持。

<?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:aop="http://www.springframework.org/schema/aop"
	xmlns:tx="http://www.springframework.org/schema/tx"
	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.xsd
						http://www.springframework.org/schema/aop
						http://www.springframework.org/schema/aop/spring-aop.xsd
						http://www.springframework.org/schema/tx
						http://www.springframework.org/schema/tx/spring-tx.xsd">

	<!-- 加载属性文件 -->
	<context:property-placeholder location="classpath:jdbc.properties" />

	<!-- 数据源 -->
	<bean id="ds" class="com.mchange.v2.c3p0.ComboPooledDataSource">
		<property name="driverClass" value="${driverClass}" />
		<property name="jdbcUrl" value="${jdbcUrl}" />
		<property name="user" value="${user}" />
		<property name="password" value="${password}" />
	</bean>

	<!-- 本地会话工厂bean，用于创建SessionFactory -->
	<bean id="sessionFactory"
		class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
		<property name="dataSource" ref="ds" />
		<!-- 注入Hibernate相关属性 -->
		<property name="hibernateProperties">
			<props>
				<prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>
				<prop key="hibernate.show_sql">true</prop>
				<prop key="hibernate.hbm2ddl.auto">update</prop>
			</props>
		</property>
		<!-- 注入hbm映射文件 -->
		<property name="mappingDirectoryLocations">
			<list>
				<value>classpath:com/kiwi/bos/domain</value>
			</list>
		</property>
	</bean>

	<!-- 组件扫描 -->
	<context:component-scan base-package="com.kiwi.bos"/>
	<context:annotation-config/>

	<!-- 事务管理器 -->
	<bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
		<property name="sessionFactory" ref="sessionFactory"/>
	</bean>

	<!-- 事务注解 -->
	<tx:annotation-driven transaction-manager="txManager"/>
</beans>

(4) 配置jdbc.properties

driverClass=com.mysql.jdbc.Driver

jdbcUrl=jdbc:mysql:///bos?useUnicode=true&characterEncoding=utf8

user=admin

password=123456

(5) 配置log4j.properties

### direct log messages to stdout ###

log4j.appender.stdout=org.apache.log4j.ConsoleAppender

log4j.appender.stdout.Target=System.err

log4j.appender.stdout.layout=org.apache.log4j.PatternLayout

log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

### direct messages to file mylog.log ###

log4j.appender.file=org.apache.log4j.FileAppender

log4j.appender.file.File=d:/mylog.log

log4j.appender.file.layout=org.apache.log4j.PatternLayout

log4j.appender.file.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

### set log levels - for more verbose logging change ‘info‘ to ‘debug‘ ###

### fatal error warn info debug trace

log4j.rootLogger=info, stdout
