需要加载的配置文件内容(resource.properties):
#FTP相关配置
#FTP的IP地址
FTP_ADDRESS=192.168.1.121
FTP_PORT=21
FTP_USERNAME=ftpuser
FTP_PASSWORD=root
FTP_BASE_PATH=/home/ftpuser/taotao/images
#图片服务器的相关配置
#图片服务器的基础URL
IMAGE_BASE_URL=http://192.168.1.121/images
实现在applicationContext.xml中需要配置加载的配置文件:
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd"> <!-- 加载配置文件 --> <context:property-placeholder location="classpath:resource/*.properties" /> </beans>
然后使用注解方式获取配置文件中的信息:
package com.taotao.service.impl; import com.taotao.service.PictureService; @Service public class PictureServiceImpl implements PictureService { @Value("${FTP_ADDRESS}") private String FTP_ADDRESS; @Value("${FTP_PORT}") private Integer FTP_PORT; @Value("${FTP_USERNAME}") private String FTP_USERNAME; @Value("${FTP_PASSWORD}") private String FTP_PASSWORD; @Value("${FTP_BASE_PATH}") private String FTP_BASE_PATH; @Value("${IMAGE_BASE_URL}") private String IMAGE_BASE_URL; }
这样既可以使用配置文件中的字段了。
