Question

我有一个xml，其中包含我想用velocity生成的类的描述，格式如下：

<Class name="name">
  <Attribute name="name" type="typeName"/>
  ...
  <Method name="name" type="typeName"/>
</Class>

模板的代码是：

public class $class.Name implements NodeIface {

#foreach($att in $class.Attributes)
  private $att.Type $att.name;

  public $att.Type get$utility.firstToUpperCase($att.Name)() {
    return this.$att.Name;
  } 

  public void set$utility.firstToUpperCase($att.Name)($att.Type $att.Name) {
    this.$att.Name = $att.Name;
  }
#end

#foreach($mtd in $class.Methods)
  if($class.Name == "name") {
    public $mtd.Name() {
      this.$att.Name = new $att.Type(Constants.SERVER_PORT, classNameHandler.class); //here lies the error
    }

    @Override
       public $mtd.Type $mtd.Name() throws TException {
         TSocket $att.Name = new TSocket("localhost", Constants.SERVER_PORT);
         TBinaryProtocol $att.Name = new TBinaryProtocol($att.Name);
         managementClient = new ManagementService.Client($att.Name);
         this.setDispatcher(new OperationDispatcher($att.Name));
         arithmeticServerTransport.open();
         $att.Name.start();
                $att.Name = new $att.Type($att.Name);
        PortNegotiator negotiator = new PortNegotiator($att.Name);
        negotiator.negotiate($att.Type, $att.Name);
    }

    @Override
    public $mtd.Type $mtd.Name() {
        $att.Name.stop();
    }
  }
  else if ($class.Name == "GreetingsNode") {
    public $mtd.Name();
        this.$att.Name = new $att.Type((Constants.SERVER_PORT, GreetingsServiceHandler.class));
    }

    #Override
    public $mtd.Type $mtd.Name() throws TException {
        TSocket $att.Name = new TSocekt("localhost", Constants.SERVER_PORT);
        TBinaryProtocol $att.Name = new TBinaryProtocol($att.Name);
        $att.Name = new ManagementService.Client($att.Name);
        this.SetUser(new User($att.Name);
        this.setMessenger(new MessageDispatcher($att.Name));
        $att.Name.open()

        $att.Name = new $att.Type($att.Name);
        PortNegotiator negotiator = new PortNegotiator($att.Name);
        negotiator.negotiate($att.Type, $att.Name);
    }

    @Override
    public $mtd.Type $mtd.Name() {
      $att.Name.stop();
    }

#End

Eclipse的速度文本编辑器告诉我这条消息有错误：＆＃34;遇到＆＃34;）; \ r \ n \ t \ t} \ r \ n \ t \ t \ r \ n \ t \ t @ Override \ r \ n \ t \ tpublic＆＃34;在Class.vm [第23行，第86栏] 期待以下之一：＆＃34; [＆＃34; ... ＆＃34;＆＃34; ... ＆＃34;）＆＃34; ... ...＆＃34;

这是什么意思？

Answer 1

这是您需要使用formal reference notation：

的情况

      this.$att.Name = new ${att.Type}(Constants.SERVER_PORT, classNameHandler.class);

否则Velocity解析器会认为您正试图在$att.Type对象上调用方法。
