将Spring Boot集成到传统应用程序中

我想将Spring Boot集成到现有应用程序之一中。所以我决定先从POC开始。我从http://www.journaldev.com/3531/spring-mvc-hibernate-mysql-integration-crud-example-tutorial下载了一个示例工作代码，并尝试集成Spring Boot。我更改了pom.xml并添加了一个新的Java类Application。下面是他们两个。将Spring Boot集成到传统应用程序中

的pom.xml

Application.java

package com.journaldev.spring; 

import org.springframework.boot.SpringApplication; 
import org.springframework.boot.autoconfigure.EnableAutoConfiguration; 
import org.springframework.boot.autoconfigure.SpringBootApplication; 
import org.springframework.context.ApplicationContext; 
import org.springframework.context.annotation.Configuration; 
import org.springframework.context.annotation.ImportResource; 


@EnableAutoConfiguration 
@ImportResource("file:/home/gd_java/program_files/projects/SpringMVCHibernate/src/main/webapp/WEB-INF/spring/appServlet/servlet-context.xml") 
public class Application { 

public static void main(String[] args) { 
    ApplicationContext ctx = SpringApplication.run(Application.class, args); 
}

}

当我运行的应用程序它被部署没有任何错误。但是当我尝试访问它时，我在Web浏览器中出现错误。

Whitelabel Error Page 
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Not Found, status=404).

这只是意味着'/ error'没有被映射。其他东西失败了，没有'/ error'的映射。其他任何东西都显示在您的控制台上吗？ – shyam

尝试在Application.java文件中使用@SpringBootApplication注释。
