这正是模型到文本(M2T)项目中的JET组件的用途.实际上,您甚至可以使用JET创建项目,.classpath和任何其他文件.

Jet模板如下.请注意,这些模板必须完全按照所示命名.

/templates/main.jet

Let c:iterate tags set the XPath context object.

For 100% compatibility with JET 0.9.x or earlier, remove this statement

--%>

--- traverse input model, performing calculations and storing

--- the results as model annotations via c:set tag

com.lacqui.commands

com.lacqui.commands

- Derive the class name from the name of the command

Command

false

--- traverse annotated model, performing text generation actions

--- such as ws:file, ws:folder and ws:project

/templates/classpath.jet

/templates/project.jet

org.eclipse.jdt.core.javabuilder

org.eclipse.jdt.core.javanature

/templates/class.jet

package ;

public class extends Command {

public ResponseCode execute() {

Server srv = getServer();

if (srv.hasCapability(Capabilities.) == false) {

Log.debug("Attempting non-available capability: ");

}

String = getArgument("");

if ( == null) {

throw new InvalidArgumentException("Require ");

}

String command = "GROUP";

if ( != null) command += " - " + ;

srv.send(command);

return srv.getResponse();

}

}

并使用此模型：

给出一个名为com.lacqui.commands的完整java项目,其中包含三个java文件：

package com.lacqui.commands;

public class ArticleCommand extends Command {

public ResponseCode execute() {

Server srv = getServer();

if (srv.hasCapability(Capabilities.READER) == false) {

Log.debug("Attempting non-available capability: READER");

}

String article-id = getArgument("article-id");

if (article-id == null) {

throw new InvalidArgumentException("Require article-id");

}

String message-id = getArgument("message-id");

String command = "GROUP";

if (article-id != null) command += " -article-id " + article-id;

if (message-id != null) command += " -message-id " + message-id;

srv.send(command);

return srv.getResponse();

}

}

还有这个：

package com.lacqui.commands;

public class GroupCommand extends Command {

public ResponseCode execute() {

Server srv = getServer();

if (srv.hasCapability(Capabilities.LOGGER) == false) {

Log.debug("Attempting non-available capability: LOGGER");

}

if (srv.hasCapability(Capabilities.AUTHENTICATOR) == false) {

Log.debug("Attempting non-available capability: AUTHENTICATOR");

}

String groupname = getArgument("groupname");

if (groupname == null) {

throw new InvalidArgumentException("Require groupname");

}

String command = "GROUP";

if (groupname != null) command += " -groupname " + groupname;

srv.send(command);

return srv.getResponse();

}

}
