Read context.xml in Spring Boot Embedded Tomcat

Question

While converting non spring application to Spring Boot want to use existing context.xml file in embedded tomcat.

Using Spring Boot 1.5.1 and Tomcat 8.5.11

TomcatEmbeddedServletContainerFactory Configuration

@Bean
public TomcatEmbeddedServletContainerFactory tomcatFactory() {
    return new TomcatEmbeddedServletContainerFactory() {

        @Override
        protected TomcatEmbeddedServletContainer getTomcatEmbeddedServletContainer(Tomcat tomcat) {
            tomcat.enableNaming();
            return super.getTomcatEmbeddedServletContainer(tomcat);
        }

        @Override
        protected void postProcessContext(Context context) {
            // Try-1 - Not Working
            if (context instanceof StandardContext) {
                StandardContext standardContext = (StandardContext) context;
                standardContext.setCopyXML(true);
            }

            // Try-2 - Not Working
            context.setConfigFile(Paths.get("/META-INF/context.xml").toFile().toURI().toURL());

            // Try-3 - Working - But due to very large and multiple configuration, java config will be cumbersome
            ContextResource resource = new ContextResource();
            resource.setName("jdbc/myDB");
            resource.setType(DataSource.class.getName());
            resource.setAuth("Container");
            resource.setProperty("username", "user111");
            resource.setProperty("password", "password111");
            resource.setProperty("driverClassName", "com.mysql.cj.jdbc.Driver");
            context.getNamingResources().addResource(resource);
       }
}

Method for checking database connection,

public void checkDb() {
    Context initContext = new InitialContext();
    Context envContext = (Context) initContext.lookup("java:/comp/env");
    DataSource datasource = (DataSource) envContext.lookup("jdbc/myDB");
    Connection con = datasource.getConnection();
}

So how to load existing context.xml in Spring Boot.

I think as a variant you can configure path to your tomcat dir and use it in spring boot spring doc with embedded container.

I also try to add server.tomcat.basedir = target/tomcat in application.properties and added context.xml in conf directory but that doesn't help. – Sheel Feb 15 '17 at 11:29
