运行
通过java命令启动
java -classpath /root/hsql/hsqldb-2.4.1/hsqldb/lib/hsqldb.jar org.hsqldb.Server -database.0 file:/home/hsqldbfile/jxima/hqdb -dbname.0 hqdb
1
-classpath表示启动需要依赖的jar包，指定到hsql安装目录下的对应地址
org.hsqldb.Server 表示server模式启动
-database.0 表示第一个数据库
file 表示数据库文件存储路径
-dbname.0 表示第一个数据库名称

使用数据库
项目中数据库配置文件配置
jdbc.url=jdbc:hsqldb:hsql://10.223.138.236(服务器IP)/hqdb (hqdb为数据库启动时配置的-dbname)
jdbc.username=sa
jdbc.password=
