我最近在我的应用程序中启动了Spring Boot。在使用tomcat8时，有一个文件上传实用程序可以正常工作，但在切换到Spring boot之后，它就不工作了

下面是代码

JSP

Spring启动配置：

@EnableAutoConfiguration(exclude = { DataSourceAutoConfiguration.class, MultipartAutoConfiguration.class })
@Configuration  
@ComponentScan
@ImportResource(value = "classpath:/context.xml")
public class MyApplication {

public MyApplication() {
    super();
}

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

我已经在我的启动应用程序类上尝试了@SpringBootApplication，但是没有用。我正在使用嵌入式tomcat

我搜索了各种各样的博客等问题，但都没能解决。

请提供帮助。

Spring启动和文件上载工作正常。文件是可用的。在默认配置下，它的多部分文件上传是开箱即用的

从您发布的代码来看，我认为您没有正确配置Spring Boot。开始例如，我看到MyApplication中没有@SpringBootApplication注释，该注释触发Spring Boot来实现标准配置。

他有@EnableAutoConfiguration、@ComponentScan和@configuration，其中@SpringBootApplication只是一个较短的版本。对。。。这让我怀疑他是否正确配置了Spring Boot。常见的问题解决策略是从已知的良好配置开始——仅@SpringBootApplication——确认功能，然后添加变量。添加@SpringBootApplication不会改变任何事情，它只是3个注释的简写。它不会改变任何东西。不，我的建议是删除所有其他注释，并按照我提供给Spring Boot教程的链接中指定的@SpringBootApplication开始。这将使您处于已知的良好状态，从该状态可以确认文件上载至少正常工作，然后根据需要开始更改配置。无论如何，这就是你应该如何使用Spring Boot的。从基本配置开始，直到基本配置不适合为止，此时您开始调整配置。这同样不会改变任何内容，因为这只不过是他已有的3个注释而已。。。另外，你所说的Spring Boot对于一个新的应用程序来说也是正确的。他正在移植一个完全不同的应用程序……你是在运行嵌入式tomcat还是仍在部署？
