读取spring配置文件的方法(spring读取资源文件)

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

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

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);
}

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;
}
}

<!-- 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>
