如何在Spring Boot中使用CommonsMultipartResolver [英] How to use CommonsMultipartResolver in Spring Boot
问题描述
我试图在Boot中将CommonsMultipartResolver用于将旧应用程序(WAR)转换为Boot,现在它获得了以下代码:
I have tried to use CommonsMultipartResolver in Boot translating my old application (WAR) to Boot, and right now it got the following code:
@Configuration
public class TestConfig {
@Bean
public FilterRegistrationBean openEntityManagerFilterRegistrationBean() {
// Set upload filter
final MultipartFilter multipartFilter = new MultipartFilter();
final FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean(multipartFilter);
filterRegistrationBean.addInitParameter("multipartResolverBeanName", "commonsMultipartResolver");
return filterRegistrationBean;
}
@Bean
public CommonsMultipartResolver commonsMultipartResolver() {
final CommonsMultipartResolver commonsMultipartResolver = new CommonsMultipartResolver();
commonsMultipartResolver.setMaxUploadSize(-1);
return commonsMultipartResolver;
}
}
这是正确的Boot方式,导致我看到了一些要在application.properties中应用的属性。它们与定义FilterRegistrationBean的目的是否相同?
Is this the right way in Boot, cause a I saw some properties to be applied in application.properties. Would they be the same purpose than defining a FilterRegistrationBean?
# MULTIPART (MultipartProperties)
multipart.enabled=true
multipart.file-size-threshold=0 # Threshold after which files will be written to disk.
multipart.location= # Intermediate location of uploaded files.
multipart.max-file-size=1Mb # Max file size.
multipart.max-request-size=10Mb # Max request size.
任何人都可以提供任何样品如何使用它吗?谢谢。
Could anyone provide any sample how to use it? Thanks.
顺便说一下,它试图设置属性multipart.enabled = true,我得到了:
By the way, It tried to set the property "multipart.enabled=true" and I got:
Caused by: org.springframework.beans.NotWritablePropertyException: Invalid property 'enabled' of bean class [org.springframework.boot.autoconfigure.web.MultipartProperties]: Bean property 'enabled' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?
