如何在Apring Boot的yml文件中配置druid数据源，请写出相关代码

在Spring Boot的yml文件中配置Druid数据源，可以参考以下代码： ```yaml spring: datasource: druid: url: jdbc:mysql://localhost:3306/your_database?useUnicode=true&characterEncoding=utf8&useSSL=false&serverTimezone=UTC username: your_username password: your_password driver-class-name: com.mysql.cj.jdbc.Driver initial-size: 5 min-idle: 5 max-active: 20 max-wait: 60000 time-between-eviction-runs-millis: 60000 min-evictable-idle-time-millis: 300000 validation-query: SELECT 1 FROM DUAL test-while-idle: true test-on-borrow: false test-on-return: false pool-prepared-statements: true max-pool-prepared-statement-per-connection-size: 20 filters: stat,wall,log4j connection-properties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000 ``` 请将`your_database`、`your_username`和`your_password`替换为实际的数据库名称、用户名和密码。
