1、pom.xml引入druid包
為了方便其他的操作,這邊直接引入druid的starter
<dependency> <groupId>com.alibaba</groupId> <artifactId>druid-spring-boot-starter</artifactId> <version>${druid.version}</version> </dependency>
2、利用com.alibaba.druid.filter.config.ConfigTools產生公私鑰
ps: 產生的方式有兩種,一種利用命令列生成,一種直接寫個工具類別生成。本文範例直接採用工具類別產生
工具類別程式碼如下
/** * alibaba druid加解密规则: * 明文密码+私钥(privateKey)加密=加密密码 * 加密密码+公钥(publicKey)解密=明文密码 */ public final class DruidEncryptorUtils { private static String privateKey; private static String publicKey; static { try { String[] keyPair = ConfigTools.genKeyPair(512); privateKey = keyPair[0]; System.out.println(String.format("privateKey-->%s",privateKey)); publicKey = keyPair[1]; System.out.println(String.format("publicKey-->%s",publicKey)); } catch (NoSuchAlgorithmException e) { e.printStackTrace(); } catch (NoSuchProviderException e) { e.printStackTrace(); } } /** * 明文加密 * @param plaintext * @return */ @SneakyThrows public static String encode(String plaintext){ System.out.println("明文字符串:" + plaintext); String ciphertext = ConfigTools.encrypt(privateKey,plaintext); System.out.println("加密后字符串:" + ciphertext); return ciphertext; } /** * 解密 * @param ciphertext * @return */ @SneakyThrows public static String decode(String ciphertext){ System.out.println("加密字符串:" + ciphertext); String plaintext = ConfigTools.decrypt(publicKey,ciphertext); System.out.println("解密后的字符串:" + plaintext); return plaintext; }
3、修改資料庫的設定檔內容資訊
a 、修改密碼
把密碼替換成用DruidEncryptorUtils這個工具類別產生的密碼
password: ${DATASOURCE_PWD:HB5FmUeAI1U81YJrT/T6awImFg1/Az5o8imy765WkVJouOubC2H80jqmZrr8L9zWKuzS/8aGzuQ4YySAkhywnA==}
b、filter開啟config
filter: config: enabled: true
c、設定connectionProperties屬性
connection-properties: config.decrypt=true;config.decrypt.key=${spring.datasource.publickey}
spring: datasource: type: com.alibaba.druid.pool.DruidDataSource driverClassName: com.mysql.cj.jdbc.Driver url: ${DATASOURCE_URL:jdbc:mysql://localhost:3306/demo?useUnicode=true&characterEncoding=utf8&useSSL=false&serverTimezone=Asia/Shanghai} username: ${DATASOURCE_USERNAME:root} password: ${DATASOURCE_PWD:HB5FmUeAI1U81YJrT/T6awImFg1/Az5o8imy765WkVJouOubC2H80jqmZrr8L9zWKuzS/8aGzuQ4YySAkhywnA==} publickey: MFwwDQYJKoZIhvcNAQEBBQADSwAwSAJBAIvP9xF4RCM4oFiu47NZY15iqNOAB9K2Ml9fiTLa05CWaXK7uFwBImR7xltZM1frl6ahWAXJB6a/FSjtJkTZUJECAwEAAQ== druid: # 初始连接数 initialSize: 5 # 最小连接池数量 minIdle: 10 # 最大连接池数量 maxActive: 20 # 配置获取连接等待超时的时间 maxWait: 60000 # 配置间隔多久才进行一次检测,检测需要关闭的空闲连接,单位是毫秒 timeBetweenEvictionRunsMillis: 60000 # 配置一个连接在池中最小生存的时间,单位是毫秒 minEvictableIdleTimeMillis: 300000 # 配置一个连接在池中最大生存的时间,单位是毫秒 maxEvictableIdleTimeMillis: 900000 # 配置检测连接是否有效 validationQuery: SELECT 1 FROM DUAL testWhileIdle: true testOnBorrow: false testOnReturn: false webStatFilter: enabled: true statViewServlet: enabled: true # 设置白名单,不填则允许所有访问 allow: url-pattern: /druid/* # 控制台管理用户名和密码 login-username: login-password: filter: stat: enabled: true # 慢SQL记录 log-slow-sql: true slow-sql-millis: 1000 merge-sql: true wall: config: multi-statement-allow: true config: enabled: true connection-properties: config.decrypt=true;config.decrypt.key=${spring.datasource.publickey}
<dependency> <groupId>com.github.ulisesbocchio</groupId> <artifactId>jasypt-spring-boot-starter</artifactId> <version>${jasypt.verison}</version> </dependency>
方案二:使用jasypt對資料庫密碼加密
1、pom.xml引入jasypt套件
public final class JasyptEncryptorUtils { private static final String salt = "lybgeek"; private static BasicTextEncryptor basicTextEncryptor = new BasicTextEncryptor(); static { basicTextEncryptor.setPassword(salt); } private JasyptEncryptorUtils(){} /** * 明文加密 * @param plaintext * @return */ public static String encode(String plaintext){ System.out.println("明文字符串:" + plaintext); String ciphertext = basicTextEncryptor.encrypt(plaintext); System.out.println("加密后字符串:" + ciphertext); return ciphertext; } /** * 解密 * @param ciphertext * @return */ public static String decode(String ciphertext){ System.out.println("加密字符串:" + ciphertext); ciphertext = "ENC(" + ciphertext + ")"; if (PropertyValueEncryptionUtils.isEncryptedValue(ciphertext)){ String plaintext = PropertyValueEncryptionUtils.decrypt(ciphertext,basicTextEncryptor); System.out.println("解密后的字符串:" + plaintext); return plaintext; } System.out.println("解密失败"); return ""; } }
password: ${DATASOURCE_PWD:ENC(P8m43qmzqN4c07DCTPey4Q==)}
jasypt: encryptor: password: lybgeek algorithm: PBEWithMD5AndDES iv-generator-classname: org.jasypt.iv.NoIvGenerator
java -jar -Djasypt.encryptor.password=lybgeek
ps: 在生產環境中,建議使用以下方式配置金鑰,避免金鑰外洩
