無法處理部件，因爲即使現有的multipartResolver已經提供了多部分配置

Question

我嘗試實現加載照片和String對象。這是我的方法的聲明。

@RequestMapping(method = RequestMethod.PUT, consumes = MediaType.MULTIPART_FORM_DATA_VALUE) 
    public @ResponseBody ResponseEntity<UserWithPhoto> update(@RequestHeader(value="Access-key") String accessKey, 
             @RequestHeader(value="Secret-key") String secretKey, 
             @RequestPart("user") String string, 
             @RequestPart("photo") MultipartFile file) throws Exception 

這是我的多部分解析器

<beans:bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> 
    <beans:property name="maxUploadSize" value="10000000" /> 
</beans:bean> 

而且我沒有帶想法，爲什麼我得到

java.lang.IllegalStateException: Unable to process parts as no multi-part configuration has been provided 

Answer 1

我總是包裹多文件與其他性質的POJO需要：

public class FileUpload { 

    private Long id; 
    private MultipartFile file; 

    // getters and setters 
} 

筆者認爲：

<spring:url value="/myEndpoint" var="url_upload"/> 
<form:form method="POST" enctype="multipart/form-data" commandName="fileUpload" action="${url_upload}" > 

    <form:hidden path="id" /> 
    <input type="file" name="file" id="inputFile"/> 

    <input type="submit" value="Upload" /> 
</form:form>   

並在端點：

@RequestMapping(value = "/myEndpoint", method = RequestMethod.POST) 
public String uploadFile(@ModelAttribute("fileUpload") FileUpload dto, Model uiModel) { 
    // Process file 
}

嘗試添加該塊代碼添加到您的配置：

<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> 
     <property name="prefix" value="/index" /> 
     <property name="suffix" value=".jsp" /> 
</bean> 

並在web.xml上加載你的配置
