Jar package: xmlpull_1_0_5.jar, xstream-1.4.1.jar)

1. Tool class XstreamUtil

　　PackageCom. learn. util;

ImportCom. thoughtworks. xstream. XStream;

ImportCom. thoughtworks. xstream. io. xml. DomDriver;

/**

*

*@ ClassName: XstreamUtil. java

*@ Description:

*/

PublicClassXstreamUtil {

/**

* Convert bean to xml

*@ ParamObj-converted bean

*@ ReturnConvert bean to xml

*/

PublicStaticString objectToXml (Object obj ){

XStream xStream =NewXStream ();

// Use annotation conversion for xstream

XStream. processAnnotations (obj. getClass ());

ReturnXStream. toXML (obj );

}

/**

* Convert xml to bean

*@ Param<T> generic

*@ ParamXml to be converted to bean xml

*@ ParamClass corresponding to cls bean

*@ ReturnConvert xml to bean

*/

PublicStatic<T> T xmlToObject (String xml, Class <T> cls ){

XStream xstream =NewXStream (NewDomDriver ());

// Use annotation conversion for xstream

Xstream. processAnnotations (cls );

Return(T) xstream. fromXML (xml );

}

}

2. Convert Java common object classes to xml

Object Class Message. java code

　　PackageCom. learn. entity;

ImportCom. thoughtworks. xstream. annotations. XStreamAlias;

 

@ XStreamAlias ("Response ")

PublicClassMessage {

 

@ XStreamAlias ("returncode ")

PrivateString returnCode;

 

@ XStreamAlias ("returnmessage ")

PrivateString returnMessage;

 

@ XStreamAlias ("status ")

PrivateIntStatus;

 

@ XStreamAlias ("time ")

PrivateString reqTime;

 

PublicString getReturnCode (){

ReturnReturnCode;

}

 

PublicVoidSetReturnCode (String returnCode ){

This. ReturnCode = returnCode;

}

PublicString getReturnMessage (){

ReturnReturnMessage;

}

PublicVoidSetReturnMessage (String returnMessage ){

This. ReturnMessage = returnMessage;

}

PublicIntGetStatus (){

ReturnStatus;

}

PublicVoidSetStatus (IntStatus ){

This. Status = status;

}

PublicString getReqTime (){

ReturnReqTime;

}

PublicVoidSetReqTime (String reqTime ){

This. ReqTime = reqTime;

}

}

 

3. convert an XML string to an object

@ XStreamAlias
