我的问题
我有这样的servlet:
@WebServlet(name = "MemberController", urlPatterns = {"/MemberController"})
@MultipartConfig
public class MemberController extends HttpServlet {
现在的问题是,WildFly不知何故不遵守注释。当我访问URL时,这是我在浏览器中得到的内容(通过查看源HTML复制):
当我将完全相同的WAR文件重新加载到Tomcat时,注释被正确读取
我的问题是,为什么?以及如何让WildFly识别这些注释?感谢您提供的文件。是Java10。在构建过程中,我注意到:
[INFO] --- maven-war-plugin:2.2:war (default-war) @ SampleForError ---

Wildfly启动时会发出类似的警告。Wildfly 12和Java 10的某些组合在JEE7模式下无法正常工作
但是,有多种变通方法。如果你运行Wildfly,它就会工作。通过运行bin/standalone.sh-Dee8.preview.mode=true
或bin/standalone.sh-c standalone-ee8.xml

否则,在Java8中不会有任何更改
顺便说一句,您正在努力混淆正在运行的任何容器。在pom.xml
中指定servlet spec 4,但是web.xml是:
