这是我的控制器

<h3>File to upload</h3>

<form action ="upload" method="post" enctype="multipart/form-data">
<input type ="file" name ="file">
<input type ="submit" value ="submit">
</form>

为什么不给你Spring Content去？

在http://start.spring.io/生成自己的春季启动应用程序。

将这些依赖项添加到您的pom。

的pom.xml

<dependency>
    <groupId>com.github.paulcwarren</groupId>
    <artifactId>spring-content-fs-boot-starter</artifactId>
    <version>0.0.11</version>
</dependency>
<dependency>
    <groupId>com.github.paulcwarren</groupId>
    <artifactId>spring-content-rest-boot-starter</artifactId>
    <version>0.0.11</version>
</dependency>

在您的主要课程中添加UploadStore：

SpringBootApplication.java

@SpringBootApplication
public class SpringContentApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringContentApplication.class, args);
    }

    @StoreRestResource(path="upload")
    public interface UploadStore extends Store<String> {
    }
}

每个上传的文件都需要一个唯一的名称，因此我们生成一个guid并动态设置表单的操作。像这样更新html：

form.html

<script language="JavaScript">
    window.onload = function() {
        document.myform.action = get_action();
    }

    function get_action() {
        return "upload/" + guidGenerator();
    }

    function guidGenerator() {
        var S4 = function() {
           return (((1+Math.random())*0x10000)|0).toString(16).substring(1);
        };
        return (S4()+S4()+"-"+S4()+"-"+S4()+"-"+S4()+"-"+S4()+S4()+S4());
    }
</script>

<html>
    <body>
        <h3>File to upload</h3>

        <form name=myform method="post" enctype="multipart/form-data">
            <input type ="file" name ="file">
            <input type ="submit" value ="submit">
        </form>
    </body>
</html>

运行您的应用程序并为UploadStore提供一个位置：

java -jar yourapp.jar --spring.content.fs.filesystemRoot=/path/to/your/store

UploadStore和upload不是很好的名字，因为这是一个支持POST，PUT，GET和DELETE的全功能内容服务。 GET甚至支持视频流。

还可以使用UploadStore来实现Renderable，以便能够获取上传内容的格式;例如，获取上传的word文档的PDF。

和/或Searchable启用全文索引（但这也需要Apache Solr）。

它可以与Spring Data结合使用，允许您关联Spring Data Entities和Spring Content Resources。
