1.警告提示：The requested profile "pom.xml" could not be activated because it does not exit
解決方案：
步驟1在Eclipse中右鍵單擊您的項目
步驟-2單擊“屬性”
步驟-3在左側列表中選擇Maven。
步驟-4您將在右側的Active Maven Profiles文本框中注意到“pom.xml”。清除它並單擊應用。
2.maven install時錯誤提示：

解決方案：
如果紅框中你是2.0.0的話，建議你新建項目換到1.5.11試一下，如果還是不行，我也沒辦法了。。
3.maven install時錯誤提示：Error starting ApplicationContext. To display the auto-configuration report re-run your application with 'debug' enabled.

去掉這一行代碼再試下@RunWith(SpringRunner.class)，應該就好了
