Question

我刚刚升级到Spring Boot 2.3.4.RELEASE，现在尝试启动应用程序时必须遵循以下错误提示：

    2020-10-12 10:16:23.870 ERROR 651 --- [           main] o.s.boot.SpringApplication               : Application run failed

有人有同样的错误吗？问候

我必须添加springframework-bom依赖项才能正确更新所有spring依赖项！

<dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-framework-bom</artifactId>
            <version>${spring-framework.version}</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>

没有它，未更新spring-beans，spring-aop等

工厂方法'mvcResourceUrlProvider'抛出异常；嵌套的异常是java.lang.NoSuchFieldError：defaultInstance
