gridfs-spring data mongodb 操作保存文件出現couldnt save chunks

spring data mongodb 操作保存文件出現couldn't save chunks

spring data mongodb 操作保存時為什麼一直出現com.mongodb.MongoException: couldn't save chunks異常
代碼如下 ：
public GridFSFile upload(InputStream inputStream,String fileName,String fileType){
    Assert.notNull(inputStream,"輸入流不能為空!");
    Assert.notNull(fileName,"文件不能為空!");
    Assert.notNull(inputStream,"輸入流不能為空!");
        ApplicationContext ctx = new AnnotationConfigApplicationContext(SpringMongoConfig.class);
        gridOperations = (GridFsOperations) ctx.getBean("gridFsTemplate");
        GridFSFile gridfs = gridOperations.store(inputStream, fileName,fileType);
        return gridfs;
}
