首先是Spring的配置文件
applicationContext.xml
<!-- 打开注解 --> <context:annotation-config/> <!-- 扫描包,一定要扫描到相应的VO类 --> <context:component-scan base-package="com.ssh.*" /> <!-- 加载properties文件,用于往javabean中注入 --> <bean name="myproperties" class="org.springframework.beans.factory.config.PropertiesFactoryBean"> <property name="locations"> <list> <value>classpath:META-INF/app_config/properties/sysconfig.properties</value> <value>classpath:META-INF/app_config/properties/sysconfig-debug.properties</value> </list> </property> </bean> <!-- 加载properties文件,用于替换Spring 配置文件中的占位符变量(${varible}) --> <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="properties" ref="myproperties"></property> <property name="locations"> <list> <value>classpath:META-INF/app_config/properties/global.framwork.properties</value> </list> </property> </bean>
SysConfigVo
package com.ssh.service; import org.springframework.stereotype.Component; import org.springframework.bean.factory.annotation.Value; @Component public class SysConfig { //myProperties必须和applicationContext.xml中的PropertiesFactoryBean的name一样 @Value("#{myProperties}['gloable.model']") private String gloable_model; public String getGloable_model() { return gloable_model; } public void setGloable_model(String gloable_model) { this.gloable_model = gloable_model; } }
在service中使用该VO
package com.ssh.service; import javax.annotation.Resource; import org.springframework.stereotype.Service; import com.ssh.dao.UserDao; import com.ssh.entity.User; @Service public class UserService { @Resource private SysConfig sysConfig; logger.info(sysConfig.getGloable_model()); }
