Java/Velocity/Velocity Properties
Use java.util.Properties to pass in properties
<source lang="java">
import java.io.StringWriter; import java.io.Writer; import java.util.Properties; import org.apache.velocity.Template; import org.apache.velocity.VelocityContext; import org.apache.velocity.app.Velocity; public class HelloWorldProperties {
public static void main(String[] args) throws Exception {
Properties props = new Properties();
props.put("input.encoding", "utf-8");
Velocity.init(props);
Template template = Velocity.getTemplate("./src/HelloWorld.vm");
VelocityContext context = new VelocityContext();
Writer writer = new StringWriter();
template.merge(context, writer);
System.out.println(writer.toString());
}
}
//File: HelloWorld.vm Hello World!
</source>
Velocity with External Properties
<source lang="java">
import java.io.StringWriter; import java.io.Writer; import org.apache.velocity.Template; import org.apache.velocity.VelocityContext; import org.apache.velocity.app.Velocity; public class HelloWorldExternalProperties {
public static void main(String[] args) throws Exception {
Velocity.init("./src/velocity.properties");
Template template = Velocity.getTemplate("./src/HelloWorld.vm");
VelocityContext context = new VelocityContext();
Writer writer = new StringWriter();
template.merge(context, writer);
System.out.println(writer.toString());
}
}
- This is a simple example of a velocity properties file.
- Any property that is not listed here will have it"s default
- value used. The default values are located in :
- * src/java/org/apache/velocity/runtime/default/velocity.defaults
- * http://jakarta.apache.org/velocity/developer-guide.html
- as an example, we are changing the name of the velocity log
runtime.log = velocity_example.log
Hello World!
