hibernate框架总是出现数据连接错误，不频繁发生
显示某个pool的线程得不到数据库连接，session不能close。。。
都是数据库操作的错误
重启后好转
[解决办法]
Java code
package com.drp.business.util; import java.io.IOException; import javax.servlet.Filter; import javax.servlet.FilterChain; import javax.servlet.FilterConfig; import javax.servlet.ServletException; import javax.servlet.ServletRequest; import javax.servlet.ServletResponse; import org.hibernate.Session; import org.hibernate.SessionFactory; import org.hibernate.cfg.Configuration; /** * 管理session * @author Administrator * */ public class HibernateFilter implements Filter { private static ThreadLocal hibernateHolder = new ThreadLocal(); private static SessionFactory factory = null; public void destroy() { } public static Session getSession() { Session session = (Session)hibernateHolder.get(); if (session == null) { session = factory.openSession(); hibernateHolder.set(session); } return session; } public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException { try { filterChain.doFilter(servletRequest, servletResponse); } finally { Session session = (Session)hibernateHolder.get(); if (session != null) { if (session.isOpen()) { session.close(); } hibernateHolder.remove(); } } } public void init(FilterConfig filterConfig) throws ServletException { try { Configuration cfg = new Configuration().configure(); factory = cfg.buildSessionFactory(); } catch (Exception e) { e.printStackTrace(); throw new ServletException(e); } } }
