部署至阿里云服务器时出现的问题 #39
Comments
若客户端强制关闭,但是服务器还在从这个套接字通道读取数据,服务器会报“java.io.IOException: 远程主机强迫关闭了一个现有的连接。”。导致这种情况出现的原因就是,客户端异常关闭后,服务器的选择器会获取到与客户端套接字对应的套接字通道SelectionKey,并且这个key的兴趣是OP_READ,执行从这个通道读取数据时,客户端已套接字已关闭,所以会出现“java.io.IOException: 远程主机强迫关闭了一个现有的连接”的错误。通常可以忽略IOException |
我用公网ip设置host:服务器你上启动项目是不报错的,但是我客户端连接用公网ip加端口建立不起连接,然后就是那个ioException 我这边是配置host为0.0.0.0 或者 负载均衡ip 都会一直不停的报ioException |
我设置了公网ip打包进行测试,发现项目启动的时候抛出了一个异常:java.net.BindException: Cannot assign requested address: bind 提示ip地址配置错误 所以建立不了连接:我的公网ip是设置在@serverendpoint(port=8081,host="") host中,所以我不是说很清楚为什么会出现这种情况呢? |

maven打包时,@serverendpoint的host属性如果直接设置阿里云服务器公网ip,无法打包。
当我将host设置为0.0.0.0时,打包正常,客户端也能正常获取到推送的数据,但是会报一个远程主机强迫关闭了一个现有的连接。
