Question

有人使用这个工具吗？我想从我的数据库中生成一个ER图。我像这样运行SchemaSpy：

java -jar schemaSpy_5.0.0.jar -t pgsql -db mydb -host localhost -dp /home/katie/downloads/postgresql-8.0-312.jdbc3.jar -noschema -u postgres -o .

然后，我收到了错误：

  [schemaSpy_5.0.0.

    jar]/net/sourceforge/schemaspy/dbTypes/pgsql.properties

我在Xubuntu 12.04上使用PostgreSQL 9.1。

Answer 1

问题已通过以下方式解决：

使用PgJDBC当代的PostgreSQL 9.1数据库安装，而不是尝试使用PgJDBC 8.0;和
使用JDBC3驱动程序，因为SchemaSpy似乎不喜欢JDBC4驱动程序。

Answer 2

java -jar F：/schema/schemaSpy_5.0.0.jar -t postgresql -db dhis2ccem1 -host localhost -port 5432 -s public -u postgres -p root -dp F：/schema/postgresql-9.0-801。 jdbc4.jar -o output
