Spring Integration TCP配置SSL遇类解析及文件缺失错误求助

已基于Spring Integration搭建TCP客户端-服务端消息系统，启用SSL配置时出现异常。初始错误为无法解析基类org.springframework.integration.ip.tcp.connection.support.TcpSSLContextSupport，确认sslContextSupport与DefaultTcpSSLContextSupport无冲突后，运行代码触发Bean创建异常，根源是类路径资源client.ks不存在。

配置代码 #

<bean id="sslContextSupport"
      class="org.springframework.integration.ip.tcp.connection.DefaultTcpSSLContextSupport">
    <constructor-arg value="client.ks"/>
    <constructor-arg value="client.truststore.ks"/>
    <constructor-arg value="secret"/>
    <constructor-arg value="secret"/>
</bean>

<int-ip:tcp-connection-factory id="clientConnectionFactory"
                           type="client"
                           host="localhost"
                           port="1234"
                           ssl-context-support="sslContextSupport" />

错误日志 #

初始编译错误 #

Cannot resolve required base class 'org.springframework.integration.ip.tcp.connection.support.TcpSSLContextSupport' 

运行时Bean创建异常日志 #

问题分析与解决步骤 #

1. 初始基类解析错误：Spring Boot 3.1.0默认适配Spring Integration 6.1.x，手动指定的spring-integration-ip版本6.1.0是匹配的。可尝试刷新Maven/Gradle依赖、清理IDE缓存，确保依赖同步正常。
2. 证书文件缺失问题：
   • 将client.ks和client.truststore.ks放置在项目src/main/resources目录下，确保编译后进入类路径。
   • 若证书存放在子目录，需指定完整路径，例如classpath:cert/client.ks（对应src/main/resources/cert目录）。
   • 检查文件名拼写，注意大小写是否匹配。
3. SSL上下文验证：确认构造参数中的密码secret与证书实际设置一致，密码错误也会导致SSLContext创建失败。
