早上好
我正在使用Java 8、Spring 5.3.29和Sping Boot 2.7.14开发REST API,当我尝试在Eclipse中的Tomcat 9服务器上启动应用程序时,我遇到了下一个问题:

GRAVE: Error during ServletContainerInitializer processing

当我在SpringServletContainerInitializer.java:157上调试停止时,它是:

initializers.add((WebApplicationInitializer)
                                ReflectionUtils.accessibleConstructor(waiClass).newInstance());

waiClass是:class org.springframework. Boot .autoconfigure.jersey.JerseyAutoConfiguration$JerseyWebApplicationInitializer
我的pom.xml是:

        return application.sources(Application.class);
    }
    
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

}

我该怎么办?
谢谢你,谢谢!

解决了!Apache CXF正在将Spring Core 3.0.7导出到Tomcat服务器的WEB-INF/lib文件夹中,并且正在重写Spring Core 5.3.29,该版本在pom.xml上配置并包含ReflectionUtils.accessibleConstructor方法。
解决方案是不将Apache CXF库导出到WEB-INF/lib。所以:
右键单击Project -> Properties -> Java Build Path -> Apache CXF,删除将Apache CXF库导出到WEB-INF/lib的选项。
再见了!
