Cách thêm tệp context.xml vào máy chủ tomcat nhúng

Question

Tôi đang cố chạy ứng dụng của mình trong máy chủ tomcat được nhúng bằng Spring-boot. Tôi đang có Tài nguyên và Môi trường JNDI được định cấu hình trong tệp XML, được đặt dưới src/main/webapp/META-INF/context.xml trong ứng dụng của tôi. Khi tôi triển khai ứng dụng này trong một thùng chứa servlet tiêu chuẩn, nó hoạt động. Nhưng khi tôi bắt đầu nó bằng cách sử dụng một máy chủ nhúng nó không nhận ra các tài nguyên JNDI có mặt trong các tập tin ngữ cảnh.

Tôi đã thử thêm tệp ngữ cảnh vào trình nhúngTomcatContainer bằng cách sử dụng mã sau đây. Được tham chiếu từ số này blog -

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

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

      Context context = new StandardContext(); 
      File f = new File("D:\\Workspace\\SpringBoot\\src\\main\\webapp\\META-INF\\context.xml"); 


      try { 
       context.setConfigFile(f.toURI().toURL()); 
       tomcat.getHost().addChild(context); 
      } catch (MalformedURLException e) { 
       // TODO Auto-generated catch block 
       e.printStackTrace(); 
      } 
      return super.getTomcatEmbeddedServletContainer(tomcat); 
     } 

Nhưng tôi nhận được ngoại lệ sau đây. Ai đó có thể vui lòng cho tôi biết cách thêm tệp context.xml vào máy chủ tomcat được nhúng không?

EDIT:

Tôi cũng thử một số API tomcat hơn để tải các tập tin context.xml (trong đó có nhiều tài nguyên JNDI và Môi trường quy định) để các trường hợp máy chủ nhúng, nhưng tôi cứ bị một Null Pointer ngoại lệ. PFB các API khác nhau mà tôi đã cố gắng sử dụng.

1. tomcat.addContext("/my-boot", System.getProperty("user.dir")+ "/src/main/webapp/META-INF/context.xml"); 

2. StandardContext context = new StandardContext(); 
context.setDefaultContextXml(System.getProperty("user.dir") + "/src/main/webapp/META-INF/context.xml"); 
tomcat.getHost().addChild(context); 

Đối với cả hai cách tiếp cận, tôi nhận được NullPointerException trong khi tomcat đang tìm cách lấy tên tài nguyên của mình. Bằng tên của các phương thức API, tôi cảm thấy rằng cần có một cách để thực hiện điều này. Hãy hỗ trợ với điều này.

Answer 1

Bạn có thể thử một cái gì đó như thế này, nhập khẩu tomcat nhúng của bạn context.xml như một nguồn lực:

@Configuration 
@EnableAutoConfiguration 
@ComponentScan 
@ImportResource("classpath:context.xml") 
public class Application { 

    public static void main(String[] args) throws Exception { 
     new SpringApplicationBuilder() 
       .showBanner(false) 
       .sources(Application.class) 
       .run(args); 
} 

@Bean 
public TomcatEmbeddedServletContainerFactory tomcatFactory() { 
    return new TomcatEmbeddedServletContainerFactory() { 
     @Override 
     protected TomcatEmbeddedServletContainer getTomcatEmbeddedServletContainer(
       Tomcat tomcat) { 
      tomcat.enableNaming(); 
      return super.getTomcatEmbeddedServletContainer(tomcat); 
     } 
    }; 
} 

EDIT: Tuy nhiên, việc thực hiện ở trên sẽ yêu cầu Xuân XSD để phân tích cú pháp thông qua các xml tài liệu theo cách thủ công vì chúng tôi đang cố gắng tùy chỉnh đọc vùng chứa được nhúng.

Vì vậy, nó luôn luôn là tốt hơn để đi cấu hình java cách để tùy biến cấu hình nhúng của context.xml, đây là tài liệu tham khảo doc khởi động mùa xuân cho một cái gì đó như thế:

http://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-developing-web-applications.html#boot-features-embedded-container

Hoặc nếu bạn sẽ chỉ muốn sử dụng jndi, bạn có thể tham khảo một cái gì đó như this

Hy vọng điều này sẽ hữu ích.
