Class SimpleConnectionFactory
java.lang.Object
org.springframework.erlang.connection.SimpleConnectionFactory
- All Implemented Interfaces:
- InitializingBean, ConnectionFactory
public class SimpleConnectionFactory
- extends Object
- implements ConnectionFactory, InitializingBean
A simple implementation of ConnectionFactory
that return a new connection
for each invocation of the createConnection method.
Note that use of this ConnectionFactory with ErlangTemplate has unstable behavior when
invoked frequently and will be deprecated. See SingleConnectionFactory
for an
alternative implementation.
Provides a more traditional API to creating a connection to a remote erlang node than
the JInterface API.
The following is taken from the JInterface javadocs that describe the valid
node names that can be used. These naming constraints apply to the string values
you pass into the node names in SimpleConnectionFactory's constructor.
About nodenames: Erlang nodenames consist of two components, an alivename and
a hostname separated by '@'. Additionally, there are two nodename formats:
short and long. Short names are of the form "alive@hostname", while long
names are of the form "alive@host.fully.qualified.domainname". Erlang has
special requirements regarding the use of the short and long formats, in
particular they cannot be mixed freely in a network of communicating nodes,
however Jinterface makes no distinction. See the Erlang documentation for
more information about nodenames.
The constructors for the AbstractNode classes will create names exactly as
you provide them as long as the name contains '@'. If the string you provide
contains no '@', it will be treated as an alivename and the name of the local
host will be appended, resulting in a shortname. Nodenames longer than 255
characters will be truncated without warning.
Upon initialization, this class attempts to read the file .erlang.cookie in
the user's home directory, and uses the trimmed first line of the file as the
default cookie by those constructors lacking a cookie argument. If for any
reason the file cannot be found or read, the default cookie will be set to
the empty string (""). The location of a user's home directory is determined
using the system property "user.home", which may not be automatically set on
all platforms.
