写字节流转换String 代码示例

     public void pushEmployee(EmpPushToTianFangRequest request){
         try {
             StringWriter sw = new StringWriter();
             JAXBContext context = JAXBContext.newInstance(EmpPushToTianFangRequest.class);
             Marshaller marshaller = context.createMarshaller();
             marshaller.marshal(request, sw);
             System.out.println(sw.toString());
         } catch (JAXBException e) {
             e.printStackTrace();
         }
     }

marshal方法在JDK中的声明:

 void javax.xml.bind.Marshaller.marshal(Object jaxbElement, Writer writer) throws JAXBException

使用

StringWriter   接受

Writer
