1.spring配置文件

复制代码 代码如下:
<bean id="configproperties"
class="org.springframework.beans.factory.config.PropertiesFactoryBean">
<property name="location" value="classpath:jdbc.properties"/>
</bean>

2.读取属性方法

复制代码 代码如下:
ApplicationContext c=new ClassPathXmlApplicationContext("classpath:applicationContext-datasource.xml");
Properties p=(Properties)c.getBean("configproperties");
System.out.println(p.getProperty("jdbcOrcale.driverClassName"));


另一个朋友提供的读取spring配置文件的方法，也分享一下吧

直接读取方式:
复制代码 代码如下:
public void test() throws IOException
{
Resource resource = ApplicationContextFactory.getApplicationContext().getResource("classpath:com/springdemo/resource/test.txt");

File file = resource.getFile();
byte[] buffer =new byte[(int) file.length()];
FileInputStream is =new FileInputStream(file);

is.read(buffer, 0, buffer.length);

is.close();
String str = new String(buffer);
System.out.println(str);

}

通过spring配置方式读取：
复制代码 代码如下:
package com.springdemo.resource;

import org.springframework.core.io.Resource;

public class ResourceBean {

private Resource resource;

public Resource getResource() {
return resource;
}

public void setResource(Resource resource) {
this.resource = resource;
}
}

spring bean配置:

复制代码 代码如下:
<!-- 可以直接将一个文件路径赋值给Resource类型的resource属性,spring会根据路径自动转换成对应的Resource -->
<bean id="resourceBean" class="com.springdemo.resource.ResourceBean" >
<property name="resource" value="classpath:/com/springdemo/resource/test.txt" ></property>
</bean>
