Question

我们正在使用spring boot开发一个REST应用程序，我们将在JOnAS 5.x上部署它，这是一个servlet 2.5容器。我们使用Spring Boot Legacy从spring documentation获得帮助。该应用程序适用于嵌入式tomcat，但是当我们通过eclispe在JOnAS 5.x上部署此应用程序时，它会给出如下错误：

Caused by: java.lang.NoClassDefFoundError: org/springframework/web/context/WebApplicationContext
at java.lang.Class.getDeclaredFields0(Native Method)
at java.lang.Class.privateGetDeclaredFields(Unknown Source)
at java.lang.Class.getDeclaredFields(Unknown Source)

我们的pom.xml如下

应用程序配置如下：

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;
import org.springframework.context.annotation.ComponentScan;

@SpringBootApplication
@EnableAutoConfiguration
@ComponentScan(basePackages="com.shilpi.rest.configuration")
public class Application extends SpringBootServletInitializer {
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Application.class);
    }
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

Spring boot legacy的链接。我在互联网上广泛搜索，但没有得到任何相关的答案。如果有人可以请求帮助。

使用Spring Boot Legacy的Spring Boot应用程序提供了NoClassDefFoundError
