1.spring配置文件

2.读取属性方法

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

直接读取方式:

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：

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:
