public class UserContorller extends HttpServlet{ 
	private static final long serialVersionUID = 1L;


	@Override
	public void service(ServletRequest req, ServletResponse res) throws ServletException, IOException { 
		try {
			IerpTransactionManagerProxy tx = getTransactionManager();
			BaseDAO dao = new BaseDAO();
			String a = req.getParameter("a");
			String b = req.getParameter("b");
			
			dao.executeUpdate("UPDATE BD_AREACL SET def4='"
					+ b + "' WHERE PK_AREACL='0001F8100000000009NM'");
			BusinessException exception = null;
			if("1".equals(a)) {
				exception = new BusinessException();
			} 
			tx.end(exception);
			res.getWriter().write("200 ok");
		} catch (Exception e) { 
			res.getWriter().write("403 get ERRORs!");
			e.printStackTrace();

	private IerpTransactionManagerProxy getTransactionManager() throws Exception {
		IerpTransactionManagerProxy txp = new IerpTransactionManagerProxy();
		txp.begin(1, 2);
		return txp;
	}
}

 

注意： txp.begin(1, 2); 此處的參數很重要，通常 1 2 是普通事務，3  2 是新起一個新子事務， 0， 0 只讀線程 無事務！

參考代碼，其餘的原理同樣.
