Spring boot 2.1.0和Java 11-JSP未加载

Question

我厌倦了调查这个问题，我找不到一个合适的答案。其实我没发现有人用Java 11和Spring。我的JSP没有加载，就这么简单。关于我的项目的一些信息:

Spring Boot version: 2.0.5.RELEASE
Java version: 11
Gradle: 4.10.2

这些是我的application.yml属性:

server:
  contextPath: /mypath
  port: 9012
  display-name: my app

#logging:

我的jsp文件位于：

/parent-project-folder/my-app/src/main/webapp/WEB-INF/jsp/

我的主要班级：

@SpringBootApplication(exclude = { SecurityAutoConfiguration.class })
public class Application extends SpringBootServletInitializer {

    /** The log. */
    private static final Logger LOG = LoggerFactory.getLogger(Application.class);

    /**
     * The main method.
     *
     * @param args the arguments
     */
    public static void main(String[] args) {
        SpringApplication springApplication = new SpringApplication(Application.class);
        springApplication.addListeners(new ApplicationPidFileWriter(System.getProperty("user.home") + File.separator + "app.pid"));
        springApplication.run(args);

        LOG.info("--------------------------------------------------------------");
        LOG.info("--------- application startup complete --------");
        LOG.info("--------------------------------------------------------------");
    }

    /*
     * (non-Javadoc)
     *
     * @see org.springframework.boot.web.support.SpringBootServletInitializer#configure(org.springframework.boot.builder.SpringApplicationBuilder)
     */
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Application.class);
    }

}

我甚至尝试将我的WEB-INF文件夹放在 /src/main/resources.

我有一个登录名.jsp根目录，我应该能够像这样 https://localhost:9012/mypath/login.html，它不会加载。

我正在取得一些进展。我将详细介绍我的应用程序。最初，这个应用程序是使用Java 1.8和Spring 1.5.9.RELEASE和BOM为我的开发编写的。该应用程序曾经在此路径下具有GET控制器：“/登录”。这是棘手的部分：每当你点击网址“https://www.myapp.com/login.htm”时，以某种方式/某种方式，我不明白，Spring设法将“登录.htm”的请求发送到控制器“/login”。我不确定它是如何意识到额外的“.htm”的。

现在，由于我使用的是Java11和Spring2.1.0.RELEASE，这不再有效。如果我点击“/login”，它将转到控制器。但我需要进行透明的迁移，我不能改变逻辑。该应用程序服务于请求，而客户端从几年前就开始使用“/login.htm”。我需要使“/login.htm”转到“/login”。

看起来您在tomcat中运行应用程序。所以检查它使用的java版本。如果版本低于应用程序java版本，tomcat就不会运行它。
