openfire(一)：使用idea編譯openfire4.2.3源碼

最近公司項目要使用openfire，并對源碼做一些修改，使用的openfire版本為官網目前最新版本4.2.3，網上資料較少，踩了很多坑，特此記錄。

1.下載源碼

http://www.igniterealtime.org/downloads/source.jsp

2.使用idea導入源碼

File-New-Project from Existing Sources 導入解壓后的源碼

一路next

導入后的目錄結構如下

設置Project SDK

打開File-Project Structure（本人使用的jdk1.8）

3.使用ant編譯源碼

　　a)打開右側ant build菜單，點擊+號，選擇openfire-src-build下的build.xml文件

　　b)點擊ant build菜單藍色按鈕（第四個）過濾

　　c)選擇openfire后點擊run按鈕

4.配置運行參數

　　a)選擇application

　　b)設置一些啟動參數如圖所示

　　c)啟動（注意：此步會報一些錯，下面一一解決）

Q:Error:java: 無效的源發行版: 1.9

A：此處選擇8

?Q：Error:(571, 21) java: 無法訪問org.apache.tools.ant.Task

　　找不到org.apache.tools.ant.Task的類文件

?

A:缺少ant包

?　　 1.將idea路徑下或者自己下載的ant.jar復制到openfire_src>build->ib>ant目錄和openfire_src>build->ib>merge目錄下

? ?　? ?2.打開project structure，選擇libraries下的ant和merge，將剛才的ant.jar添加進去

　　? ?3.選擇project structure-modules-tools模塊，加入ant依賴

?Q:啟動成功，打開控制臺頁面報

HTTP ERROR 404

Problem accessing /login.jsp. Reason:

    /login.jsp

A:在web>WEB-INF>web.xml中添加

<jsp-config>
    <taglib>
        <taglib-uri>admin</taglib-uri>
        <taglib-location>/WEB-INF/admin.tld</taglib-location>
    </taglib>
</jsp-config>
然后使用ant重新編譯后啟動

Q:再次啟動后報500錯誤

HTTP ERROR 500

Problem accessing /setup/index.jsp. Reason:

    Server Error

A:缺少配置文件
　　1.將D:\IntelliJ IDEA 2017.3.3\workspace\openfire_src\src\resources\jar下的admin-sidebar.xml復制到D:\IntelliJ IDEA 2017.3.3\workspace\openfire_src\out\production\openfire_src
　　2.將D:\IntelliJ IDEA 2017.3.3\workspace\openfire_src\src\i18n下的所有文件復制到D:\IntelliJ IDEA 2017.3.3\workspace\openfire_src\out\production\openfire_src

成功進入控制臺!!!
