NamedQuery

JAVA 代码:

   1.
      @Entity
   2.
      @NamedQuery(name="findByName", queryString =
   3.
      "SELECT o FROM People o WHERE o.name = :queryname")
   4.
      public class People{
   5.
      ...
   6.
      }

则对接口public List<People> findByNamedQueryAndNamedParam(String queryName, String[] paramNames, Object[] values);
调用

JAVA 代码:

   1.
      List<People> peoples=XXXXXXX.findByNamedQueryAndNamedParam("findByName",
   2.
         new String[]{"queryname"},new String[]{"ABCD"});

相当于将name为findByName的queryString中的queryname参数换成ABCD.
效果就相当于执行SELECT o FROM People o WHERE o.name = 'ABCD'
