在配置了spring.datasource.dynamic.datasource.master.druid.public-key的情况下。但是没有配置spring.datasource.dynamic.druid.connection-properties就会出现

spring:
  datasource:
    dynamic:
      datasource:
        master:
          url: xxx
          username: xx
          password: xx
          driver-class-name: com.mysql.cj.jdbc.Driver
          druid:
            public-key: xxx

# 防止空指针问题
spring:
  datasource:
    dynamic:
      druid:
        # noinspection SpringBootApplicationYaml
        connection-properties: config.decrypt=true
