2.nacos的yaml的相关配置配置密码和相关算法
jasypt:encryptor:algorithm: PBEWithHmacSHA512AndAES_256password: encryptionkey
3.配置数据源连接 3.1 数据库连接配置 使用ConfigurationProperties(prefix spring.datasource)注解的dataSource()方法通过DataSourceBuilder.create().build();创建了一个DataSource的bean。这个bean的配置信息来自于application.properties或application.yml文件中的spring.datasource前缀下的配置项比如数据库URL、用户名、密码等。 重点: 密码在yaml是加密的,如ENC(N8VBWG5nOHvy5efX3/mlPAmdBykE7iDZFl362LyeaPRXMbLT0PzEIlB/KDXrNYz6)配置了jasypt之后使用password作为密钥进行加密解密。
#加密

4.连接数据库配置类详解DataSourceConfig。 通过配置类的方式实现数据库的连接构建StringEncryptor 的bean对象实现密码的加密解密把加密解密串放到配置文件中用ENC()包裹着加载配置文件的时候有ENC()就会自动解密这样避免配置文件密码泄露的风险。 Beanpublic StringEncryptor stringEncryptor() {PooledPBEStringEncryptor encryptor new PooledPBEStringEncryptor();SimpleStringPBEConfig config new SimpleStringPBEConfig();config.setPassword(encryptionkey); // 加密密钥config.setAlgorithm(PBEWithHmacSHA512AndAES_256);config.setKeyObtentionIterations(1000);config.setPoolSize(1);config.setProviderName(SunJCE);config.setSaltGeneratorClassName(org.jasypt.salt.RandomSaltGenerator);config.setStringOutputType(base64);encryptor.setConfig(config);return encryptor;}
