Spring boot application.yml 中的 Spring Kafka SSL 设置

使用Spring Boot创建Kafka消费者和生产者应用程序时，可以通过在application.yml配置文件中设置Spring Kafka SSL来实现安全通信。在本文中，我们将探讨如何使用Spring Kafka SSL配置，以及如何编写代码来实现安全的Kafka应用程序。

yaml
spring:
  kafka:
    bootstrap-servers: 
    ssl:
      trust-store-location: <信任证书库路径>
      trust-store-password: <信任证书库密码>
      key-store-location: <密钥证书库路径>
      key-store-password: <密钥证书库密码>
      key-password: <密钥密码>
