解决方案

我的包类增加了新的领域,并写有getter和setter。

 私有String chat_id = NULL;
私人字符串custom_packet = NULL;
私人字符串USER_ID = NULL;
私人字符串MANAGER_ID = NULL;
私人字符串TIME_STAMP = NULL;
私人字符串website_id = NULL;
私人字符串visitor_name = NULL;
私人字符串END_TIME = NULL;




公共字符串getChat_id(){
    返回chat_id;
}

公共无效setChat_id(字符串chat_id){
    this.chat_id = chat_id;
}

公共字符串getCustom_packet(){
    返回custom_packet;
}

公共无效setCustom_packet(字符串custom_packet){
    this.custom_packet = custom_packet;
}

公共字符串getUser_id(){
    返回USER_ID;
}

公共无效setUser_id(字符串USER_ID){
    this.user_id = user_ID的;
}

公共字符串getManager_id(){
    返回MANAGER_ID;
}

公共无效setManager_id(字符串MANAGER_ID){
    this.manager_id = MANAGER_ID;
}

公共字符串getTime_stamp(){
    返回TIME_STAMP;
}

公共无效setTime_stamp(字符串TIME_STAMP){
    this.time_stamp = TIME_STAMP;
}

公共字符串getWebsite_id(){
    返回website_id;
}

公共无效setWebsite_id(字符串website_id){
    this.website_id = website_id;
}

公共字符串getVisitor_name(){
    返回visitor_name;
}

公共无效setVisitor_name(字符串visitor_name){
    this.visitor_name = visitor_name;
}

公共字符串getEnd_time(){
    返回END_TIME;
}

公共无效setEnd_time(字符串END_TIME){
    this.end_time = END_TIME;
}
 

然后我说这PacketParserUtils类parseMessage()方法。

  // ------------------------------自定义属性---- -------------------------
    message.setChat_id(parser.getAttributeValue(,chat_id));
    message.setCustom_packet(parser.getAttributeValue(,custom_packet));
    message.setUser_id(parser.getAttributeValue(,USER_ID));
    message.setManager_id(parser.getAttributeValue(,经理标识));
    message.setTime_stamp(parser.getAttributeValue(,TIME_STAMP));
    message.setWebsite_id(parser.getAttributeValue(,website_id));
    message.setVisitor_name(parser.getAttributeValue(,visitor_name));
    message.setEnd_time(parser.getAttributeValue(,end_time时间));

    // ------------------------------------------------ -----------------------------
 

然后我更新了消息toxml用于类()方法来此。

  // ------------------------------自定义标签---- -------------------------

    如果(getChat_id()!= NULL)
    {
        。buf.append(chat_id = \)追加(StringUtils.escapeForXML(getChat_id()))附加(\);

    }
    如果(getCustom_packet()!= NULL)
    {
        。buf.append(custom_packet = \)追加(StringUtils.escapeForXML(getCustom_packet()))附加(\);

    }
    如果(getUser_id()!= NULL)
    {
        。buf.append(USER_ID = \)追加(StringUtils.escapeForXML(getUser_id()))附加(\);

    }

    如果(getManager_id()!= NULL)
    {
        。buf.append(MANAGER_ID = \)追加(StringUtils.escapeForXML(getManager_id()))附加(\);

    }
    如果(getTime_stamp()!= NULL)
    {
        。buf.append(TIME_STAMP = \)追加(StringUtils.escapeForXML(getTime_stamp()))附加(\);

    }
    如果(getWebsite_id()!= NULL)
    {
        。buf.append(website_id = \)追加(StringUtils.escapeForXML(getWebsite_id()))附加(\);

    }
    如果(getVisitor_name()!= NULL)
    {
        。buf.append(visitor_name = \)追加(StringUtils.escapeForXML(getVisitor_name()))附加(\);

    }
    如果(getEnd_time()!= NULL)
    {
        。buf.append(end_time时间= \)追加(StringUtils.escapeForXML(getEnd_time()))附加(\);

    }

    // ------------------------------------------------ ------------------------------------

解决方案

I added new Fields in Packet Class and wrote there Getter and Setter.

private String chat_id = null;
private String custom_packet = null;
private String user_id=null;
private String manager_id=null;
private String time_stamp=null;
private String website_id=null;
private String visitor_name=null;
private String end_time=null;




public String getChat_id() {
    return chat_id;
}

public void setChat_id(String chat_id) {
    this.chat_id = chat_id;
}

public String getCustom_packet() {
    return custom_packet;
}

public void setCustom_packet(String custom_packet) {
    this.custom_packet = custom_packet;
}

public String getUser_id() {
    return user_id;
}

public void setUser_id(String user_id) {
    this.user_id = user_id;
}

public String getManager_id() {
    return manager_id;
}

public void setManager_id(String manager_id) {
    this.manager_id = manager_id;
}

public String getTime_stamp() {
    return time_stamp;
}

public void setTime_stamp(String time_stamp) {
    this.time_stamp = time_stamp;
}

public String getWebsite_id() {
    return website_id;
}

public void setWebsite_id(String website_id) {
    this.website_id = website_id;
}

public String getVisitor_name() {
    return visitor_name;
}

public void setVisitor_name(String visitor_name) {
    this.visitor_name = visitor_name;
}

public String getEnd_time() {
    return end_time;
}

public void setEnd_time(String end_time) {
    this.end_time = end_time;
}

Then i added this to PacketParserUtils Class parseMessage() method.

    // ------------------------------CUSTOM ATTRIBUTES-----------------------------
    message.setChat_id(parser.getAttributeValue("", "chat_id"));
    message.setCustom_packet(parser.getAttributeValue("", "custom_packet"));
    message.setUser_id(parser.getAttributeValue("", "user_id"));
    message.setManager_id(parser.getAttributeValue("", "manager_id"));
    message.setTime_stamp(parser.getAttributeValue("", "time_stamp"));
    message.setWebsite_id(parser.getAttributeValue("", "website_id"));
    message.setVisitor_name(parser.getAttributeValue("", "visitor_name"));
    message.setEnd_time(parser.getAttributeValue("", "end_time"));

    // -----------------------------------------------------------------------------

Then i updated the Message Class toXML() method to this.

// ------------------------------CUSTOM TAGS-----------------------------

    if(getChat_id()!=null)
    {
        buf.append(" chat_id=\"").append(StringUtils.escapeForXML(getChat_id())).append("\"");

    }
    if(getCustom_packet()!=null)
    {
        buf.append(" custom_packet=\"").append(StringUtils.escapeForXML(getCustom_packet())).append("\"");

    }
    if(getUser_id()!=null)
    {
        buf.append(" user_id=\"").append(StringUtils.escapeForXML(getUser_id())).append("\"");

    }

    if(getManager_id()!=null)
    {
        buf.append(" manager_id=\"").append(StringUtils.escapeForXML(getManager_id())).append("\"");

    }
    if(getTime_stamp()!=null)
    {
        buf.append(" time_stamp=\"").append(StringUtils.escapeForXML(getTime_stamp())).append("\"");

    }
    if(getWebsite_id()!=null)
    {
        buf.append(" website_id=\"").append(StringUtils.escapeForXML(getWebsite_id())).append("\"");

    }
    if(getVisitor_name()!=null)
    {
        buf.append(" visitor_name=\"").append(StringUtils.escapeForXML(getVisitor_name())).append("\"");

    }
    if(getEnd_time()!=null)
    {
        buf.append(" end_time=\"").append(StringUtils.escapeForXML(getEnd_time())).append("\"");

    }

    //------------------------------------------------------------------------------------

This how i was able to Recieve custom attributes in MESSAGE TAG.
