java.lang.Object org.springframework.integration.store.AbstractMessageGroupStore org.springframework.integration.jdbc.JdbcMessageStore
@ManagedResource public class JdbcMessageStore
Implementation of MessageStore
using a relational database via JDBC. SQL scripts to create the necessary
tables are packaged as org/springframework/integration/jdbc/schema-*.sql
, where *
is the
target database type.
