implements Session.Store

A Session.Store powered by Neo4j.

usage

 {

   session(Neo4jSessionStore.class);

   get("/", req  -> {
    req.session().set("name", "jooby");
   });
 }
 

The name attribute and value will be stored in a Neo4j.

options

timeout

By default, a neo4j session will expire after 30 minutes. Changing the default timeout is as simple as:

 # 8 hours
 session.timeout = 8h

 # 15 seconds
 session.timeout = 15

 # 120 minutes
 session.timeout = 120m
 

It uses GraphAware's Expire library to automatically remove expired sessions.

For embedded databases you need to configure the expire module, like:

 com.graphaware.runtime.enabled = true

 com.graphaware.module = [{
   class: com.graphaware.neo4j.expire.ExpirationModuleBootstrapper
   nodeExpirationProperty: _expire
 }]
 

The Neo4jSessionStore uses the _expire to evict sessions.

If you connect to a remote server make sure the expire module was installed. More information at .

If no timeout is required, use -1.

session label

It's possible to provide the session label using the neo4j.session.label properties.
