用Google搜尋了一下才找到解決辦法。

1、 Open the project’s properties (e.g., right-click on the project’s name in the project explorer and select “Properties”).
2、Select “Deployment Assembly”.
3、Click the “Add…” button on the right margin.
4、Select “Java Build Path Entries” from the menu of Directive Type and click “Next”.
5、Select “Maven Dependencies” from the Java Build Path Entries menu and click “Finish”.
You should see “Maven Dependencies” added to the Web Deployment Assembly definition.

簡而言之就是，右鍵工程選擇properties -》Deployment Assembly，如下

如果沒有顯示你引用的maven包，就點擊add把工程的maven包引入。我這裡是有的，很奇怪，但是我選定後remove然後重新add進工程然後apply，然後運行就可以了。eclipse好比是IDE界的windows經常報些莫名其妙的錯讓人惱火，還好有google，國內程式員vpn是必備的。
