spring - 无法启动 Spring Boot 应用程序 NoClassDefFoundError

Question

我已将 spring-boot-starter-parent 从 1.4.3 更改为 1.5.4

   <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.4.RELEASE</version>
    </parent>

这是我的java应用程序文件

 @SpringBootApplication
    @ComponentScan("com.test")
    @EnableCaching
    @EnableAsync
    @EnableAspectJAutoProxy
    @EnableAutoConfiguration(exclude = { DataSourceAutoConfiguration.class, WebMvcAutoConfiguration.class })
public class Application {

当我启动服务器时，它抛出以下错误。根据依赖关系，它应该处理像 spring-boot 这样的依赖 jar

感谢任何帮助。

Answer 1

customize中的一些代码方法com.xyz.asr.autoconfigure.asr.tomcat.AsrEmbeddedTomcatCustomizer指的是类 org.springframework.boot.context.embedded.ErrorPage 。 Spring Boot 1.5 中不存在该类。 ErrorPage 的正确完全限定名称是 org.springframework.boot.web.servlet.ErrorPage .

AsrEmbeddedTomcatCustomizer需要更新才能使用 org.springframework.boot.web.servlet.ErrorPage .
