我正在尝试部署使用JAXRS到Wildfly服务器的Spring Boot应用程序。
当我这样做时，我收到以下错误：

}
错误之前的最后一条INFO消息是关于部署类test.spring.boot.jaxrs.demo.JerseyConfig。我目前看不出这个代码有什么问题，并且使用Tomcat 8.5.5在Spring Tools Suite中部署了。
有谁知道可能导致问题的原因是什么？
JerseyConfig类：
package psd2.spring.boot.jaxrs.demo;
import javax.annotation.PostConstruct;
import javax.ws.rs.ApplicationPath;
import org.glassfish.jersey.server.ResourceConfig;
import org.springframework.stereotype.Component;
@Component
@ApplicationPath("/")
public class JerseyConfig extends ResourceConfig {
@PostConstruct
private void init() {
packages("io.swagger.api");
}
}

更新：我已将JerseyConfig.java代码恢复为上述内容并修改代码以删除应用程序路径，应用程序似乎部署但我看到403禁止错误。当使用相同的URL作为Spring启动应用程序运行时，此应用程序仍然有效。
