【树莓派】h2数据库操作相关

之前在树莓派上面操作时候,遇到一些业务方面的bug,和团队中的同事经过多次尝试,但就是难以重现用户现场的问题。

但是问题却实实在在地发生,虽然并不是必然可重现的bug,但是也比较闹心;

发生了问题,也只能通过数据库,直接操作,作为临时解决方案。

这里记录一下,操作h2数据库的相关的信息。

---------------------------------------------

操作分两种,一种通过linux shell下的命令行方式操作,另外一种是在Web Console的操作,类似与MySQL上面采用PHPAdmin操作一样。见下面:

1、Shell Console

首先下载h2 (h2下载地址:http://pan.baidu.com/s/1slOzQpv) ,上传到盒子上(如:/home/lifeccp/jdbc/)。然后执行如下命令:

java -cp h2*.jar org.h2.tools.Shell

更加提示,依次输入database URL, JDBC driver, user name, and password,即可进入Shell Console:

sql> list

Result list mode is now on

sql> select * from test;

2、WEB Console

修改盒子上的Nginx配置,增加如下信息:

location /h2-console {

        proxy_set_header X-Real-IP $remote_addr;

        proxy_set_header X-Forwared-For $proxy_add_x_forwarded_for;

        proxy_set_header Host $http_host;

        proxy_set_header X-NginX-Proxy true;

        proxy_pass http://127.0.0.1:8090/h2-console;

        proxy_set_header Host $host;

        proxy_set_header X-Real-IP $remote_addr;

        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

        proxy_set_header Upgrade $http_upgrade;

        proxy_set_header Connection "upgrade";

     } 

重启Nginx,成功后,盒子内网环境下,直接访问http://盒子IP/h2-console/即可打开H2 WEB Console。

select * from t_study where study_instance_uid='1.2.410.200048.9496.20170301090845';
update t_study set status=1,cuid=113232 where study_instance_uid='1.2.410.200048.9496.20170301090845';

select * from t_study where study_instance_uid='1.2.840.20150323083837.345413';
select * from t_study where study_instance_uid='1.2.840.20150323085841.345435';

当连接OK之后,你就可以按照自己需要,去进行h2数据操作了。
