可能的问题原因 #

• TLS协议与加密套件不兼容：MarkLogic 10默认禁用了TLS 1.0/1.1等旧协议，若Java客户端使用的Apache HttpClient版本过低，或未配置支持TLS 1.2+，会导致无法建立安全连接，服务端直接断开无响应。
• 端口服务配置异常：检查9004端口在MarkLogic 10中是否绑定了正确的REST API服务，是否存在服务未启动、绑定地址限制（如仅允许本地访问）的情况。MarkLogic 10可能对默认端口或服务配置有调整，需确认端口映射正确。
• 连接池复用无效连接：客户端使用的Apache HttpClient连接池若未配置合理的连接校验机制，迁移后MarkLogic 10可能主动关闭闲置连接，但连接池仍持有旧连接，复用这些连接时就会触发无响应异常。建议设置validateAfterInactivity参数，确保复用前验证连接有效性。
• 认证权限配置不符：MarkLogic 10对认证机制做了强化，比如默认启用更严格的身份验证策略，若客户端的认证信息（用户名密码、证书）不符合要求，服务端可能拒绝响应但不返回明确错误，导致客户端抛出该异常。
• 网络层面拦截：迁移后防火墙、负载均衡器的规则未更新，阻止了客户端到MarkLogic 10 9004端口的流量；或网络超时设置过短，请求未完成就被中断，引发无响应异常。
