method to read the spring configuration file (Spring reads the resource file) _java

1.spring configuration file

Copy Code code as follows:

<bean id= "Configproperties"
class= "Org.springframework.beans.factory.config.PropertiesFactoryBean" >
<property name= "Location" value= "Classpath:jdbc.properties"/>
</bean>

2. Read Property methods

Copy Code code as follows:

ApplicationContext c=new classpathxmlapplicationcontext ("Classpath:applicationcontext-datasource.xml");
Properties P= (properties) C.getbean ("Configproperties");
System.out.println (P.getproperty ("Jdbcorcale.driverclassname"));

Another friend provides a way to read the spring configuration file and share it.

Direct Read mode:

Copy Code code as follows:

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);

}

Read through Spring configuration:

Copy Code code as follows:

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 Configuration:

Copy Code code as follows:

<!--can assign a file path directly to the resource property of the resource type, and spring will automatically convert to the corresponding resource based on the path-->
<bean id= "Resourcebean" class= "Com.springdemo.resource.ResourceBean" >
<property name= "Resource" value= "Classpath:/com/springdemo/resource/test.txt" ></property>
</bean>
