Spring @Value注解使用

在ApplicationContext.xml中配置

	 <bean id="configProperties" class="org.springframework.beans.factory.config.PropertiesFactoryBean">
		 <property name="locations">
			 <list>
				 <value>classpath:imgConfig.properties</value>
			 </list>
		 </property>
	 </bean>
	 <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PreferencesPlaceholderConfigurer">
		 <property name="properties" ref="configProperties" />
	 </bean>

创建配置文件 imgConfig.properties

imgUploadUrl=C:/develop/upload/image/

使用@Value获取属性

@Value("#{configProperties['imgUploadUrl']}")
private String imgUpload;
