使用Java EE / JPA检索数据库元信息

Question

I need to be able to retrieve database information from any type of database and return this information via a restful service (using Glassfish and JAX-RS).

The information I need includes:

• Database names
• Table names
• Column names and properties

I am currently looking into DatabaseMetaData and seems to provide what I require.

However, I wanted to check if there are alternatives I should be considering (such as JPA2).

Any pointers would be appreciated

Answer 1

I settled on using SchemaCrawler . It is highly configurable and provides me with everything I need.
