标签：object pool

Open source: common-remote-pool

Apache common object pool can help user to manager resource, but if use it , you will find you can only share resources in one machine,not between multi-process or multi-machine. So we use the object pool to constructor one web service to provide distributed pool to share resources between multiple machines. The web common remote pool provide one default implement which can add any json string to pool and borrow json resource from it.What’s more, the resource object factory’s class can be uploaded into the web service. In short, the project is restful style web object pool for global access.

How to initial it

1. mvn tomcat7:run to start the webservice;

2. If you need define your implement, you should upload your resource factory class , if you have no need, omit this step.

client style

The client’s code amount is so small that you can copy the code directly.

        com.googlecode.common.remote.pool.client.CommonRemotePoolClient.borrowObject(Class<T>)
        com.googlecode.common.remote.pool.client.CommonRemotePoolClient.returnObject(Object)
        com.googlecode.common.remote.pool.client.CommonRemotePoolClient.addObject(Object...)
