跟我一起学extjs5(27--服务端web,spring,hibernate配置文件的加入)

        我们前面创建项目的时候是一个java web project，现在在项目中需要加入spring，hibernate,sqlserver连接的jar包以及加入配置文件。spring我现在使用的是3.1版本，hibernate使用的是3.0,具体的jar包以及一些附加包，请自行下载后加到工程中。（所有的jar包在我的前一个博客中提供的演示软件中有）

        一、在java Resources的src中加入一些package。在src目录下建立文件hibernate.cfg.xml和log4j.properties。

        hibenate的配置文件如下：/application5.01/src/hibernate.cfg.xml   

        （使用的是sql server数据库，用其他数据库也可以。）

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
     "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
	<session-factory>

		<property name="hibernate.connection.driver_class">com.microsoft.sqlserver.jdbc.SQLServerDriver</property>
		<property name="hibernate.connection.url">jdbc:sqlserver://10.211.55.5:1433;databaseName=haiyu</property>

		<property name="hibernate.dialect">org.hibernate.dialect.SQLServerDialect</property>
		<property name="hibernate.connection.username">sa</property>
		<property name="hibernate.connection.password"></property>

		<property name="hibernate.connection.autocommit">false</property>
		<property name="format_sql">true</property>
		<property name="show_sql">true</property>

	</session-factory>
</hibernate-configuration>

        系统日志配置文件：/application5.01/src/log4j.properties 。

log4j.rootCategory=error, console

log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern=%-4r [%t] %-5p %c %x - %m%n

log4j.logger.org.hibernate=error
log4j.logger.org.hibernate.SQL=error
log4j.logger.com.jfok=error
log4j.logger.org.springframework=error

#log4j.category.org.hibernate.type=debug

二、修改web.xml文件，加入spring的设置。

        在WEB-INF目录下需要修改web.xml ,并加入二个spring 的配置文件applicationContext.xml和dispatcherServlet-servlet.xml。

      web.xml的文件内容：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
              http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
	version="2.5" xmlns="http://java.sun.com/xml/ns/javaee">

	<!-- spring 监听器 -->
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
	
	<!-- spring 配置文件地址 -->
	<context-param>
		<param-name>ContextConfigLocation</param-name>
		<param-value>
			/WEB-INF/applicationContext.xml
		</param-value>
	</context-param>

	<!-- Servlets -->

	<!-- spring MVC，其配置文件为 <servlet-name>-servlet.xml,这里为“dispatcherServlet-servlet.xml” -->
	<servlet>
		<servlet-name>dispatcherServlet</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<load-on-startup>1</load-on-startup>
	</servlet>
	<servlet-mapping>
		<servlet-name>dispatcherServlet</servlet-name>
		<url-pattern>*.do</url-pattern>
		<!-- 用于匹配/rest/module/remove.do/{id} 之类的调用 -->
		<url-pattern>/rest/*</url-pattern>
	</servlet-mapping>

	<!-- 字符集编码过滤，防止某些乱码 -->
	
	<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>

	<!-- Default page to serve 180 -->
	<welcome-file-list>
		<welcome-file>/index.jsp</welcome-file>
	</welcome-file-list>
	<session-config>
		<session-timeout>180</session-timeout>
	</session-config>

	<jsp-config>
		<jsp-property-group>
			<url-pattern>*.jsp</url-pattern>
			<trim-directive-whitespaces>true</trim-directive-whitespaces>
		</jsp-property-group>
	</jsp-config>

</web-app>

applicationContext.xml的内容：

<?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:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context"
	xsi:schemaLocation="

		http://www.springframework.org/schema/tx/spring-tx-3.1.xsd
		http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context-3.1.xsd">

	<context:annotation-config />
	<context:component-scan base-package="com.jfok">
		<!-- 将控制层排除在外，只扫描生成服务层的DAO层的类 -->
		<context:exclude-filter type="annotation"
			expression="org.springframework.stereotype.Controller" />
	</context:component-scan>
	<tx:annotation-driven transaction-manager="transactionManager" proxy-target-class="true"/>

	<!-- spring用于替换hibernateSessionFactory.java的sessionFactory -->
	<bean id="sessionFactory"
		class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
		<property name="configLocation" value=http://www.mamicode.com/"classpath:hibernate.cfg.xml">>

dispatcherServlet-servlet.xml的内容：

<?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:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context"
	xsi:schemaLocation="
		http://www.springframework.org/schema/beans 
		http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
		
		http://www.springframework.org/schema/mvc
		http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd
		
		http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context-3.1.xsd
		">

	<!-- ①：对web包中的所有类进行扫描，以完成Bean创建和自动依赖注入的功能 , 只对标注为@Controller 的类进行分成，这些类是mvc的控制层 -->
	<context:component-scan base-package="com.jfok" use-default-filters="false">
		<context:include-filter type="annotation"
			expression="org.springframework.stereotype.Controller" />
	</context:component-scan>

	<!-- ②：启动Spring MVC的注解功能，完成请求和注解POJO的映射 -->
	<mvc:annotation-driven />

	<bean
		class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping" />

	<bean
		class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />
	<bean
		class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter"></bean>

	<!-- Configure the multipart resolver -->
	<bean id="multipartResolver"
		class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
		<!-- one of the properties available; the maximum file size in bytes -->
		<property name="maxUploadSize" value=http://www.mamicode.com/"10000000" />>        （由于使用的spring的annotation注解进行开发，因此配置文件在以后开发过程中基本上不用修改。）

三、将index.html改名为index.jsp。

四、在tomcat中发布此工程。如果运行时没有出错信息，则说明所有的配置和jar包都正确了。
