Question

我正在将Spring项目迁移到Spring Boot中。但是，当我运行应用程序时，我得到了这个异常

我在SpringApplication Class中使用它

@SpringBootApplication
@ComponentScan(basePackages = "com.app")
public class MyApplication extends SpringBootServletInitializer {

    @Bean
    public EmbeddedServletContainerFactory servletContainer() {
        TomcatEmbeddedServletContainerFactory factory = new TomcatEmbeddedServletContainerFactory();
        return factory;
    }

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application;
    }

    public static void main(String[] args) {
        SpringApplication.run(MyApplication.class, args);
    }
}

关于为什么我可能遇到这个问题的任何想法以及如何解决它？

这是我的傻瓜：

compile('org.springframework.boot:spring-boot-starter-web')
compile group: 'org.springframework.boot', name: 'spring-boot-starter-tomcat', version: '1.5.3.RELEASE'
compile 'org.apache.tomcat:catalina:6.0.53'
compile 'org.apache.tomcat:coyote:6.0.53'

Answer 1

卸下：

@Bean
public EmbeddedServletContainerFactory servletContainer() {
    TomcatEmbeddedServletContainerFactory factory = new TomcatEmbeddedServletContainerFactory();
    return factory;
}

替换：

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application;
    }

使用：

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(MyApplication.class);
    }

spring-boot-starter-web工件会导致spring-boot-starter-tomcat，因此无需将其明确地包含在您的gradle文件中，请将其删除。

卸下：

compile 'org.apache.tomcat:catalina:6.0.53'
compile 'org.apache.tomcat:coyote:6.0.53'

在使用spring-boot-starter-tomcat spring-boot-starter-web时，Tomcat（8.5.14的传递依赖关系）会带来Spring Boot，1.5.3.RELEASE的受支持版本

Answer 2

您需要更新maven依赖项，尝试执行：

std::stringstream或mvn install

将执行完整的maven生命周期。

你也可以看看这里：

找不到Spring Boot Tomcat类
