1、引入jasypt依赖库：
<!-- Jasypt核心库 -->
<dependency>
<groupId>org.jasypt</groupId>
<artifactId>jasypt</artifactId>
<version>1.9.3</version>
</dependency>
2、修改配置
spring.jdbc.username=ENC(pxXd2wjuqNv6VbOegtaUxg==)
spring.jdbc.password=ENC(8Fr/wXgInniWSazqDRU2PyaZwpnQJAqX)
3、修改数据库配置文件
<!-- 数据源配置 --><bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close"><property name="url" value="#{app['spring.jdbc.url']}" /><property name="username" value="#{app['spring.jdbc.username']}" /><property name="password" value="#{app['spring.jdbc.password']}" /><property name="filters" value="slf4j" /><property name="maxActive" value="#{app['spring.jdbc.maxActive']}" /><property name="initialSize" value="#{app['spring.jdbc.initialSize']}" /><property name="minIdle" value="#{app['spring.jdbc.minIdle']}" /><!-- 配置获取连接等待超时的时间 --><property name="maxWait" value="#{app['spring.jdbc.maxWait']}" /><!-- 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 --><property name="timeBetweenEvictionRunsMillis" value="60000" /><!-- 配置一个连接在池中最小生存的时间，单位是毫秒 --><property name="minEvictableIdleTimeMillis" value="300000" /><property name="validationQuery" value="SELECT 'x'" /><property name="testWhileIdle" value="true" /><property name="testOnBorrow" value="false" /><property name="testOnReturn" value="false" /><property name="connectProperties"><props><prop key="appPrivateKeyFilePath">密钥</prop></props></property><property name="userCallback" ref="dbNameCallback"/><property name="passwordCallback" ref="dbPasswordCallback" /></bean><bean id="dbPasswordCallback" class="com.stock.capital.agent.api.controller.DbPasswordCallback"><property name="encPassword" value="#{app['spring.jdbc.password']}" /></bean><bean id="dbNameCallback" class="com.stock.capital.agent.api.controller.DbNameCallback"><constructor-arg index="0" value="密钥" /><property name="encUserName" value="#{app['spring.jdbc.username']}" /></bean>
4、编写生成加密串代码
public static void main(String[] args) {// 注意：加密密钥必须与生产环境一致String encryptionPassword = "密钥";StandardPBEStringEncryptor encryptor = new StandardPBEStringEncryptor();encryptor.setAlgorithm("PBEWithMD5AndDES");encryptor.setPassword(encryptionPassword);String plainText = "用户名";String encryptedText = encryptor.encrypt(plainText);System.out.println("加密后的文本: ENC(" + encryptedText + ")");StandardPBEStringEncryptor decryptor = new StandardPBEStringEncryptor();decryptor.setAlgorithm("PBEWithMD5AndDES");decryptor.setPassword(encryptionPassword);String decryptedText = decryptor.decrypt(encryptedText);System.out.println("解密后的文本: " + decryptedText);}
