示例如下

package com.zz.flow.utils;
import org.activiti.engine.impl.interceptor.Command;
import org.activiti.engine.impl.interceptor.CommandContext;
import org.activiti.engine.impl.persistence.entity.ByteArrayEntity;
import java.io.UnsupportedEncodingException;

try {
ByteArrayEntity resourceEntity = new ByteArrayEntity(h.getBytes("UTF-8"));
resourceEntity.setId("obj1356889910785433603");
resourceEntity.setRevision(6);
commandContext.getDbSqlSession().update(resourceEntity);
//清除缓存
commandContext.getProcessEngineConfiguration().getProcessDefinitionCache().clear();
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
return null;
}
}

调用如下

@Resource
private ManagementService managementService;

//controller中如下

managementService.executeCommand(new UpdateByteArrayCmd())
