java.sql.SQLException:在SWT中使用时数据库被锁定

我正试图通过ibatis实现，使用SWT/Jface数据绑定到DB来删除SWT表行

每当我尝试从客户端（SWT）执行插入或删除操作时，就会出现以下异常

当我试图通过ibatis直接命中DB（SQLite）时，这不会发生

下面是我正在使用SWT按钮执行的删除操作的代码部分，并尝试删除SWT表行

SWT代码

btnDeleteWorkspaceRow.addSelectionListener(new SelectionAdapter() {
      @Override
      public void widgetSelected(SelectionEvent e) {
        IStructuredSelection selection = (IStructuredSelection) m_workplaceViewer.getSelection();                       
WorkplaceDetail workplaceDetail = (WorkplaceDetail) selection.getFirstElement();
boolean confirm = MessageDialog.openConfirm(shell,                          "Confirm Delete", "Are you sure you want to delete row"+                                    + workplaceDetail.getCode() + "'?");
if (confirm) {

 **int code =186;**   (Hardcoded row value- actual DB row number)                                       
 WorkplaceDaoImpl workplaceDaoImpl = new WorkplaceDaoImpl();

try {
**WorkplaceDaoImpl.deleteWorkplaceDetail(code);**                               
} catch (SQLException e1) {
                                                e1.printStackTrace();
}
m_bindingContext.updateModels();
}
}           
});

This is Ibatis DAO implementation code which i am invoking in SWT

**WorkplacseDaoImpl.java**

public void deleteWorkplaceDetail(int code)
            throws SQLException {
         SqlSession session = sqlSessionFactory.openSession();      
         session.delete("WorkplaceDetail.deleteWorkplaceById", code);    
         session.commit();
         session.close();        
}

**Ibatis Configuration**

  <delete id="deleteWorkplaceById">
    delete from Workplace where workplaceCode=#{code}
  </delete>

Please help me to resolve this issue. I am using SQLite DB

btnDeleteWorkspaceRow.addSelectionListener（新建SelectionAdapter（））{
@凌驾
公共无效WidgeSelected（SelectionEvent e）{
IStructuredSelection=（IStructuredSelection）m_workplaceViewer.getSelection（）；
WorkplaceDetail WorkplaceDetail=（WorkplaceDetail）selection.getFirstElement（）；
boolean confirm=MessageDialog.openConfirm（shell，“confirm Delete”，“确定要删除行“++workplaceDetail.getCode（）+”？”）；
如果（确认）{
**int code=186；**（硬编码行值-实际DB行数）
WorkplaceDaoImpl WorkplaceDaoImpl=新的WorkplaceDaoImpl（）；
试一试{
**WorkplaceDaoImpl.deleteWorkplaceDetail（代码）；**
}捕获（SQLException e1）{
e1.printStackTrace（）；
}
m_bindingContext.updateModels（）；
}
}           
});
这是我在SWT中调用的Ibatis DAO实现代码
**workacsedaoimpl.java**
public void deleteWorkplaceDetail（内部代码）
抛出SQLException{
SqlSession session=sqlSessionFactory.openSession（）；
删除（“WorkplaceDetail.deleteWorkplaceById”，代码）；
commit（）；
session.close（）；
}
**Ibatis配置**
从workplaceCode=#{code}的工作区中删除
请帮我解决这个问题。我正在使用SQLite数据库

根据您的描述和之前的描述，我认为您试图同时在不同的线程中访问SQLite数据库。按钮事件处理程序代码正在SWT UI线程内部运行。您可能有其他代码试图在其他线程中连接到数据库。

是的，您是真的。。。我正在使用SQLite和Ibatis。有没有办法解决这个问题…因为我没有直接使用JDBC…而是使用ibatis。那么我如何确保单连接…而不是通过多个DB连接。我在下面添加了标记，以确保在sqlmap配置中有单活动连接，

btnDeleteWorkspaceRow.addSelectionListener(new SelectionAdapter() {
      @Override
      public void widgetSelected(SelectionEvent e) {
        IStructuredSelection selection = (IStructuredSelection) m_workplaceViewer.getSelection();                       
WorkplaceDetail workplaceDetail = (WorkplaceDetail) selection.getFirstElement();
boolean confirm = MessageDialog.openConfirm(shell,                          "Confirm Delete", "Are you sure you want to delete row"+                                    + workplaceDetail.getCode() + "'?");
if (confirm) {

 **int code =186;**   (Hardcoded row value- actual DB row number)                                       
 WorkplaceDaoImpl workplaceDaoImpl = new WorkplaceDaoImpl();

try {
**WorkplaceDaoImpl.deleteWorkplaceDetail(code);**                               
} catch (SQLException e1) {
                                                e1.printStackTrace();
}
m_bindingContext.updateModels();
}
}           
});
