从java.sql.CallableStatement调用的存储过程中检索记录

我正在创建一个webapp，用户可以在其中为某些网络文档设置警报。此日期与一堆其他数据一起存储在mysql DB中，这些数据在插入时使用AES_ENCRYPT加密。

插入的插图如下所示：

CREATE DEFINER=`service01`@`%` PROCEDURE `insert_secure_alert`(
IN master_secret VARCHAR(100), 
IN path VARCHAR(300),
IN creation DATE,
IN expiration DATE,
IN alert_name VARCHAR(300),
IN alert_comment VARCHAR(300)
)
BEGIN
INSERT INTO `fujitsu_consensus_core`.`alert`
(`id`,
`path`,
`creation`,
`expiration`,
`name`,
`comment`)
VALUES
(0,
AES_ENCRYPT(path, master_secret),
AES_ENCRYPT(creation, master_secret),
AES_ENCRYPT(expiration, master_secret),
AES_ENCRYPT(alert_name, master_secret),
AES_ENCRYPT(alert_comment, master_secret));
END

这工作得很好，但是在使用存储过程检索此数据时遇到了一些问题。负责此检索的类看起来像这样：

package com.fujitsu.database;

import java.io.IOException;
import java.sql.CallableStatement;
import java.sql.ResultSet;
import java.sql.SQLException;

import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.json.simple.JSONObject;
import org.json.simple.parser.ParseException;

import com.fujitsu.consensus.helper.StreamToJson;

public class RetrieveSecureAlert extends HttpServlet{

/**
 * 
 */
private static final long serialVersionUID = -6379032803226212817L;
protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws IOException{

    try {
        JSONObject obj = StreamToJson.convertStreamToJson(req.getInputStream());
        String path = (String) obj.get("path");

        CallableStatement cs = AccessObject.getConnectionObject().prepareCall("{CALL `fujitsu_consensus_core`.`retrieve_secure_alert`(?,?}");
        cs.setString(1, path);
        cs.setString(2, "FUJITSU");
        cs.execute();

        ResultSet result = cs.getResultSet();

        System.out.println("RESULT!");
        while(result.next()){
            System.out.println(result.getString("id"));
            System.out.println(result.getString("decryptd_path"));
            System.out.println(result.getString("decrypted_creation"));
            System.out.println(result.getString("decrypted_expiration"));
            System.out.println(result.getString("decrypted_name"));
            System.out.println(result.getString("decrypted_comment"));
        }


    } catch (ParseException e) {
        e.printStackTrace();
    } catch (SQLException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

}

}

相应的mysql存储procdure如下所示：

CREATE DEFINER=`service01`@`%` PROCEDURE `retrieve_secure_alert`(IN path_key VARCHAR(300), IN master_secret VARCHAR(100))
BEGIN

DECLARE v_encrypted_path VARBINARY(300);
DECLARE v_encrypted_creation VARBINARY;
DECLARE v_encrypted_expiration VARBINARY;
DECLARE v_encrypted_name VARBINARY(300);
DECLARE v_encrypted_comment VARBINARY(300);

SELECT path INTO v_encrypted_path FROM fujitsu_consensus_core WHERE path = AES_ENCRYPT(path_key, master_secret);
SELECT creation INTO v_encrypted_creation FROM fujitsu_consensus_core WHERE path = AES_ENCRYPT(path_key, master_secret);
SELECT expiration INTO v_encrypted_expiration FROM fujitsu_consensus_core WHERE path = AES_ENCRYPT(path_key, master_secret);
SELECT `name` INTO v_encrypted_name FROM fujitsu_consensus_core WHERE path = path = AES_ENCRYPT(path_key, master_secret);
SELECT `comment` INTO v_encrypted_comment FROM fujitsu_consensus_core WHERE path = AES_ENCRYPT(path_key, master_secret);

SELECT  id,
    AES_DECRYPT(v_encrypted_path, master_secret) AS decryptd_path,
    AES_DECRYPT(v_encrypted_creation, master_secret) AS decrypted_creation,
    AES_DECRYPT(v_encrypted_expiration, master_secret) AS decrypted_expiration,
    AES_DECRYPT(v_encrypted_name, master_secret) AS decrypted_name,
    AES_DECRYPT(v_encrypted_comment, master_secret) AS decrypted_comment
FROM fujitsu_consensus_core.alert
WHERE path = AES_ENCRYPT(path_key, master_secret);
END

所以最大的问题是，如何使用解密我的记录的java.sql.callablestatement从mysql中的存储过程中检索记录？

1 个答案:

答案 0 :(得分：0)

我发现错误但是，callablestatement中的sql字符串不能包含`但是应该包含＆＃39;
