In Spring Roo when we enable our project for JPA using the following command:-

jpa setup --provider DATANUCLEUS --database

Then I found that there is no option for MongoDB after --database option.So i want to know how can I do it.

I am thinking to create a JPA setup for MySql and then make changes in the generated persistence.xml for MongoDB cause at the end even ROO is a java project.But I don't know whether its the correct approach.

I would appreciate any assistance in doing this.Any link or example will be great.

MongoDB 有一个类似的 Roo 命令：

roo> mongo setup

并创建实体：

roo> entity mongo --class ~.domain.Pizza

无论数据存储如何，JPA 都是 JPA。只需将数据存储设置为“支持 Spring”的数据库，然后按照您的说法更新 persistence.xml。DataNucleus 对 MongoDB 的支持将忽略不适用于特定数据存储的注释（根据 DN 文档和支持的功能页面）
