将用于对象序列化的类传递给xml

How can I pass a Class as parameter and return a generic collection in Java?

How do I pass a class as a parameter in Java?

I am unsure how I would pass a JibX generated class as a parameter to a method that serializes the object.

I would like to accomplish something like the following.

protected static String SerializeObject( Class clazz , Object request)
{
    String message = null;

    try
    {
      IBindingFactory lBindingFactory = BindingDirectory.getFactory(
              clazz.class);
      IMarshallingContext lContext = lBindingFactory.
              createMarshallingContext();
      ByteArrayOutputStream lOutputStream = new ByteArrayOutputStream();
      lContext.marshalDocument(request, "UTF-8", null,
              lOutputStream);
      message = new String(lOutputStream.toByteArray(), "UTF-8");
    }
    catch (JiBXException lEx)
    {
      throw new RuntimeException("Problems generating XML, " +
            "underlying problem is " +  lEx.getMessage(), lEx);
    }
    catch (UnsupportedEncodingException lEx)
    {
      throw new RuntimeException("Problems generating XML in specified" +
              "encoding, underlying problem is " + lEx.getMessage(), lEx);
    }
    return message;
}

Where the class is only used to define what the BindingDirectory is using to serialize the object into.

Answer 1

I might be better to avoid attempting to pass the class at all. I can achieve the same affect by passing the IBindingFactory and adding a bit of code to the caller.

The result would end up like this.

protected static String SerializeObject( IBindingFactory lBindingFactory,
        Object request)
{
    String message = null;

    try
    {
      IMarshallingContext lContext = lBindingFactory.
              createMarshallingContext();
      ByteArrayOutputStream lOutputStream = new ByteArrayOutputStream();
      lContext.marshalDocument(request, "UTF-8", null,
              lOutputStream);
      message = new String(lOutputStream.toByteArray(), "UTF-8");
    }
    catch (JiBXException lEx)
    {
      throw new RuntimeException("Problems generating XML, " +
            "underlying problem is " +  lEx.getMessage(), lEx);
    }
    catch (UnsupportedEncodingException lEx)
    {
      throw new RuntimeException("Problems generating XML in specified" +
              "encoding, underlying problem is " + lEx.getMessage(), lEx);
    }
    return message;
}
