http://blog.csdn.net/qustmeng/article/details/53706657

try {  

            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);  

        } 
其中，类CharacterEscapeHandler为com.sun.xml.internal.bind.marshaller.CharacterEscapeHandler
