将SpringBoot项目部署到WLS，动态Web模块不断还原回4.0

Question

我有一个正在从事的springboot项目。我正在使用Spring Boot 2.1.3版本。我需要此版本，以便可以使用mysql连接器版本8.0.15。我正在此项目中使用Hibernate和JPA。

由于WLS 12.1.3不使用Servlet 4.0，因此出现此错误

当我将.war文件部署到Web Logic Server时，出现此错误：

Message icon - Error VALIDATION PROBLEMS WERE FOUND C:\Oracle\user_projects\domains\dev_domain\weblogic.utils.classloaders.GenericClassLoader@2ad4423 finder: weblogic.utils.classloaders.CodeGenClassFinder@3be64d51 annotation: \WEB-INF\lib\tomcat-embed-jasper-9.0.16.jar!\META-INF\web-fragment.xml:18:3:18:3: problem: cvc-enumeration-valid: string value '4.0' is not a valid enumeration value for web-app-versionType in namespace http://xmlns.jcp.org/xml/ns/javaee

我已经尝试进入org.eclipse.wst.common.project.facet.core.xml并将其中的动态Web模块设置为3.1。但是，一旦我更新了Maven项目，它就会恢复为4.0。

我还对pom文件进行了更改，以确保已使用正确的java-x servlet。这是我的pom.xml

Answer 1

Servlet规范4.0是JEE 8的一部分，尚未在WebLogic Server 12c中实现。您可以使用其他支持JEE 8和Servlets 4.0的应用程序服务器。
