Available as of Camel 2.13
The optaplanner: component solves the planning problem contained in a message with OptaPlanner.
For example: feed it an unsolved Vehicle Routing problem and it solves it.
The component supports consumer as BestSolutionChangedEvent listener and producer for processing Solution and ProblemFactChange
Maven users will need to add the following dependency to their pom.xml
for this component:
<dependency> <groupId>org.apache.camel</groupId> <artifactId>camel-optaplanner</artifactId> <version>x.x.x</version><!-- use the same version as your Camel core version --> </dependency> |
optaplanner:solverConfig[?options] |
The solverConfig is the classpath-local URI of the solverConfig, for example /org/foo/barSolverConfig.xml
.
You can append query options to the URI in the following format, ?option=value&option=value&...
Name | Default Value | Type | Context | Description |
---|---|---|---|---|
solverId | DEFAULT_SOLVER | String | Shared | The endpoint keeps a map of Solver instances. solverId specifies a the map key to use. |
threadPoolSize | 10 | int | Producer | Specifies the size the of thread pool to use for processing async Solution messages. |
async | false | Boolean | Producer | Specify whether to use another thread for submitting Solution instances rather than blocking the current thread. |
Name | Default Value | Type | Context | Description |
---|---|---|---|---|
CamelOptaPlannerSolverId | null | String | Shared | Specifies the solverId to use |
CamelOptaPlannerIsAsync | PUT | String | Producer | Specify whether to use another thread for submitting Solution instances rather than blocking the current thread. |
Camel takes the planning problem for the IN body, solves it and returns it on the OUT body.
(since v 2.16) The IN body object supports the following use cases:
The solving will take as long as specified in the solverConfig
.
<solver> ... <termination> <!-- Terminate after 10 seconds, unless it's not feasible by then yet --> <terminationCompositionStyle>AND</terminationCompositionStyle> <secondsSpentLimit>10</secondsSpentLimit> <bestScoreLimit>-1hard/0soft</bestScoreLimit> </termination> ... <solver> |
Solve an planning problem that's on the ActiveMQ queue with OptaPlanner:
from("activemq:My.Queue"). .to("optaplanner:/org/foo/barSolverConfig.xml"); |
Expose OptaPlanner as a REST service:
from("cxfrs:bean:rsServer?bindingStyle=SimpleConsumer") .to("optaplanner:/org/foo/barSolverConfig.xml"); |
