Question

我试图通过ibatis实现使用SWT / Jface数据绑定删除SWT表行。

每当我尝试从客户端（SWT）执行插入或删除操作时，我都会遇到异常。

org.apache.ibatis.exceptions.PersistenceException: 
### Error committing transaction.  Cause: java.sql.SQLException: database is locked

当我尝试直接通过ibatis命中DB（SQLite）时，不会发生这种情况。

以下是我正在使用SWT按钮并尝试删除SWT表行的删除操作的代码部分。

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

从您的描述和related question之前，我认为您正在尝试同时在不同的线程中访问SQLite数据库。 Button事件处理程序代码在SWT UI线程内运行。您可能有其他代码尝试连接到其他线程中的数据库。

java.sql.SQLException：在SWT中使用时数据库被锁定
