基于JAVA中Jersey处理Http协议中的Multipart的详解

private static WebResource webResource = client.resource("http://xxx.xx.xx:xxx");

public static final String HeadFieldName = "xmlhead";
public static final String BodyFieldName = "xmlbody";

 
// Client发送代码
public static String post(String head, String body) throws BusinessException {
        FormDataMultiPart multiPart = new FormDataMultiPart();
        multiPart.field(RequestField.HeadFieldName, head, MediaType.MULTIPART_FORM_DATA_TYPE);
        multiPart.field(RequestField.BodyFieldName, body, MediaType.MULTIPART_FORM_DATA_TYPE);
        return webResource.type("multipart/form-data").post(String.class, multiPart);
    }

// Server端接收代码
          @POST
    @Produces({MediaType.APPLICATION_XML, MediaType.MULTIPART_FORM_DATA})
    @Consumes({MediaType.APPLICATION_XML, MediaType.MULTIPART_FORM_DATA})   
    public String service(FormDataMultiPart multiPart) throws Exception{
        if(multiPart == null){
            if(_logger.isErrorEnabled()){
                _logger.error("the request FormDataMultiPart is null");
            }

            throw new Exception("the request FormDataMultiPart is null");
        }

        List<RequestField> requestFields = new ArrayList<RequestField>();
        for(BodyPart bodyPart : multiPart.getBodyParts()){
            String fieldName = ((FormDataBodyPart)bodyPart).getName().trim();
            if(fieldName.equalsIgnoreCase(RequestField.HeadFieldName)){
                requestFields.add(new RequestField(fieldName, bodyPart.getEntityAs(String.class)));
            }
            else if(fieldName.equalsIgnoreCase(RequestField.BodyFieldName)){
                requestFields.add(new RequestField(fieldName, bodyPart.getEntityAs(String.class)));
            }
            else{

                }
            }
