import javax.servlet.FilterConfig;import javax.servlet.ServletException;import javax.servlet.ServletRequest;import javax.servlet.ServletResponse;import org.hibernate.Session;import org.hibernate.Transaction;import util.HibernateUtil;public class OpenSessionInViewFilter implements Filter {    @Override    public void destroy() {            }    @Override    public void doFilter(ServletRequest request, ServletResponse response,            FilterChain chain) throws IOException, ServletException {        // 聲明對象        Session session = null;        Transaction tx = null;        // 異常處理        try {            // 開啟session            session = HibernateUtil.currentSession();            // 開始事務            tx = session.beginTransaction();
            // 執行過濾            chain.doFilter(request, response);                        tx.commit();  // 提交        } catch (Exception e) {            if(tx!=null)tx.rollback();            e.printStackTrace();        } finally {            System.out.println("關閉session");            HibernateUtil.closeSession();        }    }    @Override    public void init(FilterConfig arg0) throws ServletException {    }}

最後更改web.xml檔案配置

<filter>      <filter-name>OpenSessionInViewFilter</filter-name>       <filter-class>filter.OpenSessionInViewFilter</filter-class>  </filter><filter-mapping>    <filter-name>OpenSessionInViewFilter</filter-name>       <url-pattern>/*</url-pattern>  </filter-mapping>
