到了添加Server Library步驟時，裏面是空選項，沒有Tomcat 7.0選擇，怎麽辦？

1、選擇 eclipse 的WIndows菜單》Preferences 預設

技術分享

2、在左側列表中找到 Server 項，展開，選中：Runtime Environments，右側點擊添加按鈕

技術分享

3、這裏要根據你使用的 Tomcat 版本來選擇，不一定是 Tomcat 7.0；

我這裏是演示添加 Tomcat，當然也可以選擇添加 IBM 的 Liberty ，或者 JBoss 之類的 Web 服務器（Java EE容器）

如果你還沒有安裝 Tomcat，那可以去官網下載一個壓縮包解壓到一個目錄就可以了。

技術分享

4、點擊 Browse 按鈕選擇 Tomcat 所在的位置

選擇 JRE （Java Runtime Environment），當然你可以使用 Eclipse 自帶的，

但如果你想使用自己安裝的版本就需要添加一下；初學使用自帶的就可以了；

技術分享

5、上面一切就緒點擊 Finish 按鈕就可以了。
