我正在尝试创建一个servlet，它使用类GetTicketInfo从HTML表单读取数据，并将数据插入到类WriteToDatabase的MySQL数据库中。 问题是，当我填写了HTML表单，然后按按钮，注册票据，这应该启动数据插入到数据库的过程中我在我的浏览器中出现此错误“HTTP状态405 - HTTP方法GET不受此URL的支持“。我的index.html，其中包含表单，网址为http://localhost/IssueHandler/index.html我使用的Apache Tomcat 7.0.34服务器此方法不支持HTTP方法GET，状态405
控制台不打印任何错误，但两个警告：
WARNING: [SetPropertiesRule]{Server/Service/Engine/Host/Context} Setting property 'source' to 'org.eclipse.jst.jee.server:CDM' did not find a matching property.

我猜测它与表单无法找到servlet有关，但我真的不知道。我已经尝试将servlet映射标签等添加到web.xml文件，但它没有帮助。

要发送表单数据到服务器，您应该使用POST。 – pbespechnyi
