Spring Boot应用程序与外部Webapp之间的数据源共享

Question

我们正在组织中尝试从基于Weblogic的部署转移到基于Spring Boot的微服务。第一步，我试图创建一个Spring Boot应用程序，在这里我想将在weblogic中运行的Web应用程序（.war）作为应用程序加载到嵌入式tomcat。我想要一种配置，使运行在同一tomcat上的spring boot应用程序和webapp将通过JNDI查找共享数据源。

 @Bean
    public ServletWebServerFactory servletContainer() {
       return new TomcatServletWebServerFactory() {
           @Override
           protected TomcatWebServer getTomcatWebServer(Tomcat tomcat) {
               new File(tomcat.getServer().getCatalinaBase(), "webapps").mkdirs();
               TomcatWebServer tomcatWebServer;
               try {

                   tomcat.enableNaming();
                   Context context = tomcat.addWebapp("<context>", "<path to webapp>");
                   context.setParentClassLoader(getClass().getClassLoader());
                   WebappLoader loader =new WebappLoader(Thread.currentThread().getContextClassLoader());
                   context.setLoader(loader);


                  tomcatWebServer = super.getTomcatWebServer(tomcat);
                   Container[] children = tomcatWebServer.getTomcat().getHost().findChildren();
                   for (Container child : children) {
                       if (child instanceof Context) {
                           ClassLoader contextClassLoader =
                                   ((Context)child).getLoader().getClassLoader();
                           Thread.currentThread().setContextClassLoader(contextClassLoader);
                           break;
                       }
                   }

               } catch (Exception ex) {
                   throw new IllegalStateException("Failed to add webapp", ex);
               }

               return tomcatWebServer;
           }

            @Override
            protected void postProcessContext(Context context) {

                ContextResource resource = new ContextResource();
                resource.setAuth("Container");
                resource.setName("*****");
                resource.setType(DataSource.class.getName(`enter code here`));
                resource.setProperty("driverClassName","*****");
                resource.setProperty("url", "*****");
                resource.setScope("Sharable");
                resource.setProperty("password", "****");
                resource.setProperty("username", "*****");
                resource.setProperty("global", "****");

                ContextResourceLink contextResourceLink = new ContextResourceLink();
                contextResourceLink.setName("****");
                contextResourceLink.setGlobal("*****");
                contextResourceLink.setType(DataSource.class.getName());


                context.getNamingResources().addResource(resource);
                context.getNamingResources().addResourceLink(contextResourceLink);


            }
