我试图将照片插入到MySQL表的BLOB列中，但出现异常：

Data too long for column 'logo' at row 1.

这是JDBC：

    int idRestaurant = 42;
    String restoname=  "test";
    String restostatus=  "test";
    InputStream fileContent = getUploadedFile();
    int fileSize = getUploadedFileSize();

    Class.forName("com.mysql.jdbc.Driver");
    try (Connection conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/resto" , "root" , "" )) {
        PreparedStatement ps = conn.prepareStatement("insert into restaurants (idRestaurant, restaurantName, status, logo) values(?,?,?,?)");
        ps.setInt(1, idRestaurant);
        ps.setString(2, restoname);
        ps.setString(3, restostatus);
        ps.setBinaryStream(4, fileContent, fileSize);
        ps.executeUpdate();
        conn.commit();
    }

我该如何解决这个问题？
