Hi, ALL,
I try to write a class file generation based on Velocity, very simple,
but it doesn't work. The problem is, it will not output field type and
name.
what reason, need import something ?
Thanks.

package com;
import java.io.BufferedWriter;
import java.io.OutputStreamWriter;
import java.util.ArrayList;
import java.util.Properties;
import org.apache.velocity.Template;
import org.apache.velocity.VelocityContext;
import org.apache.velocity.app.Velocity;
import org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader;
public class Test {
public static void main(String[] args) {
VelocityContext context = new VelocityContext();
context.put("fldList", getFld());
context.put("CName", "Employee");
context.put("SName", "employee");
Template template = null;
try {
Properties p = new Properties();
p.setProperty("file.resource.loader.class",
ClasspathResourceLoader.class.getName());
Velocity.init(p);
template = Velocity.getTemplate("example.vm");
BufferedWriter writer = new BufferedWriter(new
OutputStreamWriter(System.out));
if (template != null){
template.merge(context, writer);
}
writer.flush();
writer.close();
} catch (Exception e) {
e.printStackTrace();
System.out.println(e.getMessage());
}
}
public static ArrayList<Field> getFld() {
ArrayList<Field> list = new ArrayList<Field>();
list.add(new Field("String", "name"));
return list;
}
}
class Field {
public String name;
public String type;
public Field(){ }
public Field(String type, String name){
this.type = type;
this.name = name;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getType() {
return type;
}
public void setType(String type) {
this.type = type;
}
@Override
public String toString() {
return this.name+"--"+this.type;
}
}
[/code]
vm file
[code]
public class $CName{
#foreach( $field in $fldList )
private ${field.type} ${field.name};
#end
}
[/code]
