- 由spring官方文檔可知育勺，spring-boot在
MultipartProperties配置文件中對(duì)最大上傳大小做了限制需要在啟動(dòng)時(shí)增加一個(gè)配置類
- 在啟動(dòng)類里增加以下類即可解決問題
/**
* 解除上傳文件的限制
*/
@Configuration
@ConditionalOnClass({Servlet.class, StandardServletMultipartResolver.class,
MultipartConfigElement.class})
@ConditionalOnProperty(prefix = "spring.http.multipart", name = "enabled", matchIfMissing = true)
@EnableConfigurationProperties(MultipartProperties.class)
public class MultipartAutoConfiguration {
private final MultipartProperties multipartProperties;
public MultipartAutoConfiguration(MultipartProperties multipartProperties) {
this.multipartProperties = multipartProperties;
multipartProperties.setMaxFileSize("-1");
}
@Bean
@ConditionalOnMissingBean
public MultipartConfigElement multipartConfigElement() {
return this.multipartProperties.createMultipartConfig();
}
@Bean(name = DispatcherServlet.MULTIPART_RESOLVER_BEAN_NAME)
@ConditionalOnMissingBean(MultipartResolver.class)
public StandardServletMultipartResolver multipartResolver() {
StandardServletMultipartResolver multipartResolver = new StandardServletMultipartResolver();
multipartResolver.setResolveLazily(this.multipartProperties.isResolveLazily());
return multipartResolver;
}
}
