下载Openfire源码
下载地址：https://www.igniterealtime.org/downloads/index.jsp，当前最新版本为：4.2.3
Eclipse上部署Openfire
1、把openfire源文件拷贝到Eclisps的工作目录中，我的目录是D:\eclipse-workspace
2、进入openfire_src>build>eclipse目录下，把里面settings、classpath、project三个文件拷贝到openfire_src目录，并用windows命令行重命名它们：
rename settings .settings、rename classpath .classpath、rename project .project
3、导入工程到eclipse中，发现有些错误，一些jar包missing了。
把报错的jar包remove掉，然后把build>lib下的所有jar包括文件夹里面的jar都导进来。
4、在Build Path配置中把 /openfire_src/src/i18n（支持中文） 、/openfire_src/src/resources/jar 、/openfire_src/build/lib/dist （所有依赖jar包）文件夹添加到 Source 中
5、Ant编译
在“Quick Access”中输入Ant，选择Ant
Add BuildFires
Openfire_src/build/build.xml
双击“openfire”进行编译
6、配置run_configurations
选择Java Application，新建一个配置。Main class选择Search,可以进行查询选择“org.jivesoftware.openfire.starter.ServerStarter”，并且勾选第一个复选框
配置Arguments
-DopenfireHome="${workspace_loc:openfire_src}/target/openfire"
注意：标注红色部分，对于你项目的名称。
配置Common
执行“Apply”，运行“Run”
至此源码编译环境已搭建完毕
添加消息记录保存
1、修改初始数据库文件，路径src/database/openfire_sqlserver.sql，添加ofHistory表
CREATE TABLE ofHistory ( username NVARCHAR(64) NOT NULL, messageID INTEGER NOT NULL, creationDate NVARCHAR(64) NOT NULL, messageSize INTEGER NOT NULL, stanza TEXT NOT NULL, CONSTRAINT ofHistory_pk PRIMARY KEY (username, messageID) );
2、添加保存消息方法
MessageRouter类中133行附近
// 保存消息记录——高明——2018年6月20日 15:45:46
OfflineMessageStore oms = new OfflineMessageStore();
oms.addMessage_toHistory(packet);
3、修改OfflineMessageStore类，添加保存消息记录方法
新添加
//保存消息记录——高明-2018年6月20日 15:43:59
private static final String INSERT_HISTORY = "INSERT INTO ofHistory (username, messageID, creationDate, messageSize, stanza) "
+ "VALUES (?, ?, ?, ?, ?)";
新添加
