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());
}
Spring配置:加载properties到bean
本文介绍如何在Spring框架中初始化bean,并将properties配置文件的内容注入到bean中,通过XML配置文件`applicationContext.xml`定义`SysConfigVo`,然后在service层使用该配置信息。
