List query(String sql,Ojbect[] args,RowMapper rowMapper)
说明:常用的查询,sql待执行的sql语句,args是sql语句的参数,rowMapper负责将每一行记录转化为java对象存放在list,并最终返回,例如:
Java代码 收藏代码
public List<Book> queryByAuthor(String author) {
String sql = "select * from book where author=?";
Collection c = getJdoTemplate().find(sql,
new Object[] { author },new BookRowMapper());
List<Book> books = new ArrayList<Book>();
books.addAll(c);
return books;
}
class BookRowMapper implements RowMapper{
public Object mapRow(ResultSet res, int index) throws SQLException {
Book book = new Book();
book.setId(rs.getInt("id"));
//省略set
return book;
}
}
