xml解析工具mashaller javaee自带解析类

1.怎样去掉Marshaller的格式化？

：

JAXBContext context = JAXBContext.newInstance(Entity.class);
            Marshaller marshaller = context.createMarshaller();
            // xml格式
            marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
            // 去掉生成xml的默认报文头
            marshaller.setProperty(Marshaller.JAXB_FRAGMENT, true);
            // 不进行转义字符的处理
            marshaller.setProperty(CharacterEscapeHandler.class.getName(), new CharacterEscapeHandler() {
                public void escape(char[] ch, int start,int length, boolean isAttVal, Writer writer) throws IOException {
                    writer.write(ch, start, length);
                }
            });
            StringWriter sw = new StringWriter();
            marshaller.marshal(entity, sw);
            return sw.toString();
        } catch (JAXBException e) {
            log.error("", e);
        }

2.xml就像json解析一样，正常不过，是很正常的序列化格式。
