类 JarResourceLoader

java.lang.Object

bboss.org.apache.velocity.runtime.resource.loader.ResourceLoader

bboss.org.apache.velocity.runtime.resource.loader.JarResourceLoader

public class JarResourceLoader
extends ResourceLoader

ResourceLoader to load templates from multiple Jar files.

The configuration of the JarResourceLoader is straightforward - You simply add the JarResourceLoader to the configuration via

    resource.loader = jar
    jar.resource.loader.class = bboss.org.apache.velocity.runtime.resource.loader.JarResourceLoader
    jar.resource.loader.path = list of JAR <URL>s
 

So for example, if you had a jar file on your local filesystem, you could simply do

    jar.resource.loader.path = jar:file:/opt/myfiles/jar1.jar
    

Note that jar specification for the .path configuration property conforms to the same rules for the java.net.JarUrlConnection class.

For a working example, see the unit test case, bboss.org.apache.velocity.test.MultiLoaderTestCase class

JarResourceLoader

public JarResourceLoader()

方法详细资料

init

public void init(org.apache.commons.collections.ExtendedProperties configuration)

Called by Velocity to initialize the loader

指定者:

init 在类中 ResourceLoader

参数:

configuration -

getResourceStream

public java.io.InputStream getResourceStream(java.lang.String source)
                                      throws ResourceNotFoundException

Get an InputStream so that the Runtime can build a template with it.

指定者:

getResourceStream 在类中 ResourceLoader

参数:

source - name of template to get

返回:

InputStream containing the template

抛出:

ResourceNotFoundException - if template not found in the file template path.

isSourceModified

public boolean isSourceModified(Resource resource)

从类复制的说明: ResourceLoader

Given a template, check to see if the source of InputStream has been modified.

指定者:

isSourceModified 在类中 ResourceLoader

返回:

True if the resource has been modified.

另请参阅:

ResourceLoader.isSourceModified(bboss.org.apache.velocity.runtime.resource.Resource)

getLastModified

public long getLastModified(Resource resource)

从类复制的说明: ResourceLoader

Get the last modified time of the InputStream source that was used to create the template. We need the template here because we have to extract the name of the template in order to locate the InputStream source.

指定者:

getLastModified 在类中 ResourceLoader

返回:

Time in millis when the resource has been modified.

另请参阅:

ResourceLoader.getLastModified(bboss.org.apache.velocity.runtime.resource.Resource)
