I have configured and tested in the application.properties or application.yml files according to the modification method on the Internet, but the upload still fails when running. . .
Later, I guessed that it should be covered, so my configuration did not take effect.
Workaround: Create a configuration that overrides the existing bean definition.
@Bean
public MultipartConfigElement multipartConfigElement() {
MultipartConfigFactory config = new MultipartConfigFactory();
// 设置上传文件的单个大小限制
config.setMaxRequestSize(DataSize.of(100, DataUnit.MEGABYTES));
// 设置总的上传的大小限制
config.setMaxRequestSize(DataSize.of(200, DataUnit.MEGABYTES));
// 设置临时保存目录
//config.setLocation("/");
// 创建一个上传配置并返回
return config.createMultipartConfig();
}
The file size above can be changed to suit you.
If this error is reported after running
, then according to his prompt: add spring.main.allow-bean-definition-overriding=truesuch a configuration in application.properties, it will be ok
. This configuration means:
in Spring Boot, set spring.main.allow-bean-definition-overriding= The true attribute allows overriding existing bean definitions. By default, if a bean definition exists in the application context, and another bean definition tries to register a bean with the same name, Spring Boot will throw an exception and refuse to register the new bean.
However, sometimes it may be necessary to override the existing bean definition, such as using a Mock object to replace the actual bean in the test or using a custom bean implementation to replace Spring Boot's default implementation, etc. In this case, the property spring.main.allow-bean-definition-overriding=true can be set to allow overriding of existing bean definitions.
Note that overuse of this property may cause unexpected behavior or difficult-to-diagnose problems. Therefore, it is recommended to use this property only when necessary and to avoid overwriting existing bean definitions.
