Spring Web框架搭建配置

配置web.xml文件：
在tomcat啓動時加載web.xml文件。

 <?xml version="1.0" encoding="UTF-8"?>

<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

	<!-- springMVC end -->

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

配置spring-common.xml文件：
配置了properties資源文件的加載路徑以及自動注入的掃描路徑。

<?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"
	xsi:schemaLocation="

		http://www.springframework.org/schema/context
		http://www.springframework.org/schema/context/spring-context-3.0.xsd">

	<!-- 引入屬性文件 classpath:資源文件夾根目錄 -->
	<bean id="propertyConfigurer" class="com.giser.config.CustomizedPropertyPlaceholderConfigurer">
		<property name="ignoreResourceNotFound" value="true" />
		<property name="locations">
			<list>
				<value>classpath:datasource.properties</value>
				<value>classpath:mysql-connection.properties</value>
			</list>
		</property>
	</bean> 

	<!-- 自動掃描(自動注入) -->
	<context:component-scan base-package="com.giser" />

</beans>

配置datasource.properties文件：
主要用於配置數據庫的連接信息，如驅動、方言、url、用戶名、密碼、心跳檢測語句等。

jdbc_username=gis
jdbc_password=gis
jdbc_url=jdbc:oracle:thin:@localhost:1521:giser
jdbc_driver=oracle.jdbc.driver.OracleDriver
jdbc_dialect=org.hibernate.dialect.Oracle9Dialect
validationQuery=select 1 from dual

配置spring-mybatis.xml文件：
配置了數據源、事務，接口掃描路徑等。

<?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:tx="http://www.springframework.org/schema/tx"

</beans>

配置spring-mvc.xml文件
主要配置了控制層組件掃描、視圖解析器等。

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

	<!-- 自動掃描(自動注入) -->
	<context:component-scan base-package="com.giser" />
	
	<!-- 啓用mvc註解驅動 -->
	<mvc:annotation-driven />
 
	<!-- 對模型視圖名稱的解析，即在模型視圖名稱添加前後綴 -->
	<bean 	class="org.springframework.web.servlet.view.InternalResourceViewResolver"
			p:prefix="/WEB-INF/view/" 
			p:suffix=".jsp" />
			
	<!-- 避免IE執行AJAX時,返回JSON出現下載文件 -->
	<bean id="mappingJacksonHttpMessageConverter"
		class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
		<property name="supportedMediaTypes">
			<list>
				<value>text/html;charset=UTF-8</value>
			</list>
		</property>
	</bean>

	<!-- 啓動Spring MVC的註解功能，完成請求和註解POJO的映射 -->
	<bean
		class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
		<property name="messageConverters">
			<list>
				<ref bean="mappingJacksonHttpMessageConverter" /><!-- json轉換器 -->
			</list>
		</property>
	</bean>

	<!-- 上傳文件配置bean，配置上傳文件編碼，大小，類型等 -->
	<bean id="multipartResolver"
		class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
		<property name="defaultEncoding">
			<value>UTF-8</value>
		</property>
		<property name="maxUploadSize">
			<!-- 上傳文件大小限制爲31M，31*1024*1024 -->
			<value>32505856</value>
		</property>
		<property name="maxInMemorySize">

		</property>
	</bean>

</beans>

至此就OK了。
