Hibernate常见问题集锦(2)

1。问题:

 

异常原因:

2010/10/17-22:09:40  WARN Configurator:

126 - No configuration found. Configuring ehcache from ehcache-failsafe.xml found in the classpath: jar:file:/D:/%e6%88%91%e7%9a%84%e6%96%87%e6%a1a3/workspace/ePetSSH/WebRoot/WEB-INF/lib/ehcache-1.1.jar!/ehcache-failsafe.xml

解决办法:

public List<Petinfo> search(Petinfo petinfo, String orderBy) {
  List<Petinfo> lists = null;
  String hql = "select p from Petinfo as p where 1=1";
  // 查询对象
  Query query = null;
  // 宠物名
  if (petinfo.getPetName() != null && petinfo.getPetName().trim() != "") {

   hql += " and p.petName like :petname";
   System.out.println(hql);
   query = getSession().createQuery(hql);

   query.setString("petname", "%"+petinfo.getPetName()+"%");

  }
  // 宠主
  if (petinfo.getPetOwnerName() != null
    && petinfo.getPetOwnerName().trim() != "") {

   hql += " and p.petOwnerName=:petownername";
   System.out.println(hql);
   query = getSession().createQuery(hql);
   query.setString("petname", "%"+petinfo.getPetName()+"%");
   query.setString("petownername", petinfo.getPetOwnerName());
  }
        //執行查詢
  System.err.println("Search方法的查询语句:::"+hql);
  lists = query.list();
  return lists;
 }
看到红色加粗的字体了吧!需要对重新组建的hql语句重新赋值!
