What is the method in Java for receiving blob data?

In Java, we can receive Blob data by using the getBlob method of ResultSet to retrieve the Blob object. We can then use the getBinaryStream method of the Blob object to obtain the input stream and read the Blob data. Below is an example code snippet:

// 假设resultSet是查询结果的ResultSet对象
Blob blob = resultSet.getBlob("blob_column_name");
InputStream inputStream = blob.getBinaryStream();

// 读取Blob数据
byte[] data = new byte[inputStream.available()];
inputStream.read(data);

// 关闭流
inputStream.close();

Warning: Blob data can be very large, so it is important to be cautious of potential memory overflow issues when reading Blob data.
