SpringBoot报错（一）端口被占用Address already in use: bind 今天第一次配置springboot就出现一个粗心的错误，虽然我知道怎么解决，但出错，想着就不是很舒服。这个问题的原因是端口被占用，解决方法就是修改Application里边的配置，修改调端口号在application里边加入server.port=8888 . ____ _ __ _ _ /\\ / ___'_ __ _ _(_)_ __ __ _...

springboot配置https启动总是出现端口占用 ## 避免和 server 工程端口冲突 #server.port=80 server.port=443 #证书的路径. #server.ssl.key-store=classpath:pay.xia

⋅求教：在自己定义的VIEW里面，二次调用含有editView的对话框会出错 更多帖子 关注私信空间博客 zhaohuaxishiwzw 本版专家分：50: 端口被占用了吧，打开任务管理器看是否有JAVA进程在运行，如果有可能就是该进程占用该端口。
或者，命令行netstat -ano查看端口号 8773是不是被别的程序占用了，查看进程ID，然后在任务管理器查看该进程ID的进程是什么。
如果都不是，那是不是系统禁止该端口使用。。。
