我正在嘗試創建一個servlet，它使用類GetTicketInfo從HTML表單讀取數據，並將數據插入到類WriteToDatabase的MySQL數據庫中。 問題是，當我填寫了HTML表單，然後按按鈕，註冊票據，這應該啓動數據插入到數據庫的過程中我在我的瀏覽器中出現此錯誤「HTTP狀態405 - HTTP方法GET不受此URL的支持「。我的index.html，其中包含表單，網址爲http://localhost/IssueHandler/index.html我使用的Apache Tomcat 7.0.34服務器此方法不支持HTTP方法GET，狀態405
控制檯不打印任何錯誤，但兩個警告：
WARNING: [SetPropertiesRule]{Server/Service/Engine/Host/Context} Setting property 'source' to 'org.eclipse.jst.jee.server:CDM' did not find a matching property.

我猜測它與表單無法找到servlet有關，但我真的不知道。我已經嘗試將servlet映射標籤等添加到web.xml文件，但它沒有幫助。
