Description
Current example request to POST /server/containers/{containerId}/solvers/{solverId}/state/solving:
{
"employeerostering.employeerostering.EmployeeRoster": {
"employeeList": [
{
"name": "John",
"skills": {
"employeerostering.employeerostering.Skill": {
"name": "reading"
}
}
},
{
"name": "Mary",
"skills": {
"employeerostering.employeerostering.Skill": {
"name": "writing"
}
}
},
{
"name": "Petr",
"skills": {
"employeerostering.employeerostering.Skill": {
"name": "speaking"
}
}
}
],
"shiftList": [
{
"timeslot": {
"startTime": "2017-01-01T00:00:00",
"endTime": "2017-01-01T01:00:00"
},
"requiredSkill": {
"-reference": "../../../employeeList/employeerostering.employeerostering.Employee/skills/employeerostering.employeerostering.Skill"
}
},
{
"timeslot": {
"-reference": "../../employeerostering.employeerostering.Shift/timeslot"
},
"requiredSkill": {
"-reference": "../../../employeeList/employeerostering.employeerostering.Employee[3]/skills/employeerostering.employeerostering.Skill"
}
},
{
"timeslot": {
"-reference": "../../employeerostering.employeerostering.Shift/timeslot"
},
"requiredSkill": {
"-reference": "../../../employeeList/employeerostering.employeerostering.Employee[2]/skills/employeerostering.employeerostering.Skill"
}
}
],
"skillList": [
{
"-reference": "../../employeeList/employeerostering.employeerostering.Employee/skills/employeerostering.employeerostering.Skill"
},
{
"-reference": "../../employeeList/employeerostering.employeerostering.Employee[3]/skills/employeerostering.employeerostering.Skill"
},
{
"-reference": "../../employeeList/employeerostering.employeerostering.Employee[2]/skills/employeerostering.employeerostering.Skill"
}
],
"timeslotList": {
"employeerostering.employeerostering.Timeslot": {

{
"employee": {
"-reference": "../../../employeeList/employeerostering.employeerostering.Employee"
},
"date": "2017-01-01"
}

}
}
but when I request best solution, I get:
{
"container-id" : "employeerostering_1.0.0-SNAPSHOT",
"solver-id" : "solver-json",
"solver-config-file" : "employeerostering/employeerostering/EmployeeRosteringSolverConfig.solver.xml",
"status" : "NOT_SOLVING",
"score" : {
"value" : "0hard/0soft",
"scoreClass" : "org.optaplanner.core.api.score.buildin.hardsoft.HardSoftScore"
},
"best-solution" : {"employeerostering.employeerostering.EmployeeRoster":{
"employeeList" : [ {
"name" : "John",
"skills" : [ {
"name" : "reading"
} ]
}, {
"name" : "Mary",
"skills" : [ {
"name" : "writing"
} ]
}, {
"name" : "Petr",
"skills" : [ {
"name" : "speaking"
} ]
} ],
"shiftList" : [ {
"timeslot" : {
"startTime" : [ 2017, 1, 1, 0, 0 ],
"endTime" : [ 2017, 1, 1, 1, 0 ]
},
"requiredSkill" : {
"name" : null
}
}, {
"timeslot" : {
"startTime" : null,
"endTime" : null
},
"requiredSkill" : {
"name" : null
}
}, {
"timeslot" : {
"startTime" : null,
"endTime" : null
},
"requiredSkill" : {
"name" : null
}
} ],
"skillList" : [ {
"name" : null
}, {
"name" : null
}, {
"name" : null
} ],
"timeslotList" : [ {
"startTime" : null,
"endTime" : null
} ],
"dayOffRequestList" : [ {
"employee" : {
"name" : null,
"skills" : null
},
"date" : [ 2017, 1, 1 ]
} ],
"shiftAssignmentList" : [ ],
"score" : "0hard/0soft"
}}
}
with lot of null, so the references don't work.
If I submit a solution in XML and retrieve it in JSON there are no references. All objects are serialized fully. That may work for simple objects like skills (just a string) but for example a dayOffRequest needs to reference an existing object from employeeList.
TODO: Recreate the employee rostering problem that is used in documentation and looks like this:
<employeerostering.employeerostering.EmployeeRoster> <employeeList> <employeerostering.employeerostering.Employee> <name>John</name> <skills> <employeerostering.employeerostering.Skill> <name>reading</name> </employeerostering.employeerostering.Skill> </skills> </employeerostering.employeerostering.Employee> <employeerostering.employeerostering.Employee> <name>Mary</name> <skills> <employeerostering.employeerostering.Skill> <name>writing</name> </employeerostering.employeerostering.Skill> </skills> </employeerostering.employeerostering.Employee> <employeerostering.employeerostering.Employee> <name>Petr</name> <skills> <employeerostering.employeerostering.Skill> <name>speaking</name> </employeerostering.employeerostering.Skill> </skills> </employeerostering.employeerostering.Employee> </employeeList> <shiftList> <employeerostering.employeerostering.Shift> <timeslot> <startTime>2017-01-01T00:00:00</startTime> <endTime>2017-01-01T01:00:00</endTime> </timeslot> <requiredSkill reference="../../../employeeList/employeerostering.employeerostering.Employee/skills/employeerostering.employeerostering.Skill"/> </employeerostering.employeerostering.Shift> <employeerostering.employeerostering.Shift> <timeslot reference="../../employeerostering.employeerostering.Shift/timeslot"/> <requiredSkill reference="../../../employeeList/employeerostering.employeerostering.Employee[3]/skills/employeerostering.employeerostering.Skill"/> </employeerostering.employeerostering.Shift> <employeerostering.employeerostering.Shift> <timeslot reference="../../employeerostering.employeerostering.Shift/timeslot"/> <requiredSkill reference="../../../employeeList/employeerostering.employeerostering.Employee[2]/skills/employeerostering.employeerostering.Skill"/> </employeerostering.employeerostering.Shift> </shiftList> <skillList> <employeerostering.employeerostering.Skill reference="../../employeeList/employeerostering.employeerostering.Employee/skills/employeerostering.employeerostering.Skill"/> <employeerostering.employeerostering.Skill reference="../../employeeList/employeerostering.employeerostering.Employee[3]/skills/employeerostering.employeerostering.Skill"/> <employeerostering.employeerostering.Skill reference="../../employeeList/employeerostering.employeerostering.Employee[2]/skills/employeerostering.employeerostering.Skill"/> </skillList> <timeslotList> <employeerostering.employeerostering.Timeslot reference="../../shiftList/employeerostering.employeerostering.Shift/timeslot"/> </timeslotList> <dayOffRequestList/> <shiftAssignmentList/> </employeerostering.employeerostering.EmployeeRoster>
Add a dayOffRequest and serialize the problem into JSON using Jackson. Make sure references work, it can be sent to server and best solution returns expected solution.
May require the use of @JsonIdentityInfo. See https://www.baeldung.com/jackson-annotations, https://www.baeldung.com/jackson-bidirectional-relationships-and-infinite-recursion.
