Hi liuhuaqing,

I tried following code and it works fine for me, I don't know why it causing you an error, Might be you are violating the constraint of the database table. Check your DB as well whether there is entry of this variables or not.

Map<String, Object> taskVariables = new HashMap<String, Object>();
String str1="test1";
String str2="test2";
String str3="test3";

taskVariables.put(str1, str1);
taskVariables.put(str2, str2);
taskVariables.put(str3, str3);

ProcessInstance processInstance = runtimeService.startProcessInstanceByKey("myProcess","",taskVariables);

by activiti.cfg.xml

java code :
————————————————————–

engine = ProcessEngines.getDefaultProcessEngine();
…….
runtimeService.startProcessInstanceByKey(processKey, businessID, map);

i tryed other functions that has the map parameter,the result is the same i post

here is activiti.cfg.xml:

I am not using the activiti.cfg.xml, This is how I am communicating with database,

ProcessEngine processEngine = ProcessEngineConfiguration.createStandaloneProcessEngineConfiguration()
    .setDatabaseSchemaUpdate(ProcessEngineConfiguration.DB_SCHEMA_UPDATE_FALSE)
    .setJdbcUrl("jdbc:h2:tcp://localhost/activiti;DB_CLOSE_DELAY=1000;")
    .setJdbcUsername("alfresco")
    .setJdbcPassword("alfresco")
    .setAsyncExecutorEnabled(true)
    .setAsyncExecutorActivate(false)
    .setProcessEngineName("MyEngine")
    .buildProcessEngine();

Might you get any idea,

————–the process i deployed
startEvent—->userTask—->endEvent

————–the java code

engine = ProcessEngineConfiguration.createStandaloneProcessEngineConfiguration()
    .setDatabaseSchemaUpdate(ProcessEngineConfiguration.DB_SCHEMA_UPDATE_FALSE)
    .setJdbcUrl("jdbc:mysql://localhost/activitidb")   //diferent from your
    .setJdbcUsername("root")
    .setJdbcPassword("root")
    .setAsyncExecutorEnabled(true)
    .setAsyncExecutorActivate(false)
    .setProcessEngineName("MyEngine")
    .buildProcessEngine();

Do one thing open your db and try enter values manually in that and check wehther it is working or not

Re: need help：about runtimeService.startProcessInstanceByKey（key，businessID，map）

abbask — Thu, 28 Apr 2016 10:27:34 GMT

please post your hashmap/map declaration. try passing direct string values inside put() method e.g. map.put("test2", "test2")

Re: need help：about runtimeService.startProcessInstanceByKey（key，businessID，map）

liuhuaqing — Thu, 28 Apr 2016 11:23:10 GMT

——————–
The error occurred while setting parameters
