本地運行時倒是沒啥問題，一上線啟動接連報錯。網上各種找答案，本質上還是依賴沖突報錯，不知道使用哪個具體類
Caused by: java.lang.NoSuchMethodError: javax.servlet.ServletContext.getVirtualServerName()Ljava/lang/String;The following method did not exist:javax.servlet.ServletContext.getVirtualServerName()Ljava/lang/String;The method's class, javax.servlet.ServletContext, is available from the following locations:jar:file:/css-web.jar!/BOOT-INF/lib/javax.servlet-3.0.0.v201112011016.jar!/javax/servlet/ServletContext.classjar:file:/css-web.jar!/BOOT-INF/lib/servlet-api-2.4.jar!/javax/servlet/ServletContext.classjar:file:/css-web.jar!/BOOT-INF/lib/servlet-api-2.5-6.1.14.jar!/javax/servlet/ServletContext.classjar:file:/css-web.jar!/BOOT-INF/lib/tomcat-embed-core-9.0.21.jar!/javax/servlet/ServletContext.classjar:file:/css-web.jar!/BOOT-INF/lib/javax.servlet-api-3.1.0.jar!/javax/servlet/ServletContext.classIt was loaded from the following location:jar:file:/css-web.jar!/BOOT-INF/lib/javax.servlet-3.0.0.v201112011016.jar!/上述是多版本 servlet-api 的jar報錯，做法就是排除依賴
參考: https://www.cnblogs.com/lvbinbin2yujie/p/10726122.html
java.lang.ClassNotFoundException: org.apache.jsp.index_jsp
這個報錯是依賴中的 jsp-api.jar 與tomcat中的沖突，排除依賴
java.lang.NoSuchMethodError: org.eclipse.jdt.internal.compiler.CompilationResult.getProblems()
同上，jasper-runtime沖突
最終修改
