私はxml設定を使用しますspring4はうまく動作します。このように:
<bean id="multipartResolver"
class="org.springframework.web.multipart.commons.CommonsMultipartResolver"
p:defaultEncoding="utf-8" >
<!-- one of the properties available; the maximum file size in bytes -->
<!-- <property name="maxUploadSize" value="40000000" /> -->
</bean>
このようにxml。なしでspring4を設定すると:
@Configuration
@ComponentScan({ "common.user", "service" })
@EnableWebMvc
public class SpringMVCConfig {
@Bean
public ViewResolver createInternalResourceViewResolver() {
InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
viewResolver.setViewClass(JstlView.class);
viewResolver.setContentType("text/html");
viewResolver.setPrefix("/view/");
//viewResolver.setSuffix(".jsp");
return viewResolver;
}
@Bean
public DefaultServletHttpRequestHandler createDefaultServletHttpRequestHandler() {
return new DefaultServletHttpRequestHandler();
}
@Bean
public CommonsMultipartResolver createMultipartResolver() {
CommonsMultipartResolver resolver=new CommonsMultipartResolver();
resolver.setDefaultEncoding("utf-8");
return resolver;
}
}
例外をスローします:

MultipartResolver
Javadocから:実装を定義するには、DispatcherServletのアプリケーションコンテキストでID "multipartResolver"を使用してBeanを作成します。
Xml構成では、Beanの正しいIDはmultipartResolver
ですが、現在のJava構成ではありません。
@Bean
public CommonsMultipartResolver multipartResolver() {
CommonsMultipartResolver resolver=new CommonsMultipartResolver();
resolver.setDefaultEncoding("utf-8");
return resolver;
}
または
@Bean(name = "multipartResolver")
public CommonsMultipartResolver createMultipartResolver() {
CommonsMultipartResolver resolver=new CommonsMultipartResolver();
resolver.setDefaultEncoding("utf-8");
return resolver;
}
