出现问题:
我的代码是通过本机eclipse访问电脑虚拟机安装的oracle数据库数据,出现了Io 异常: The Network Adapter could not establish the connection,这个异常是由于ui端接口发送数据进行接口访问时出现的。
处理过程:
1.修改虚拟机oracle监听配置,配置listener和tnsnames文件,这两个文件在db_home2中,不是在db_home1中,一定要注意。
2.配置了监听的主机名,一定是主机名不然没法访问,具体如下图所示。
3.修改eclipse中的application.yml文件中的连接,改成了: host:端口:SID,,在这里host是我的主机名(主机名通过计算机属性查看,后面一般带有-PC),端口是1521,注意是SID不是全局数据库名。

SQLNET配置文件:

application.yml文件配置:
注意:文件配置严格按照格式来,只能是用空格键,不能使用tab键。
