Hibernate标量查询的使用

前言

每次写标量查询都要百度一波，索性记录下来。

标量查询

• 菜单实体

public class Menu {
    private String id;
    private String name;
    private String code;
    private Float showOrder;
    /* getter/setter */
}

• 查询方法

public List<Menu> listMenus(String code) {
    String sql = "select id, name, code, showOrder from menu where code=:code";
    Session session = super.getSession();
    SQLQuery query = session.createSQLQuery(sql);
    query.addScalar("id", Hibernate.STRING);
    query.addScalar("name", Hibernate.STRING);
    query.addScalar("code", Hibernate.STRING);
    query.addScalar("code", Hibernate.FLOAT);
    query.setResultTransformer(Transformers.aliasToBean(Menu.class));
    query.setParameter("code", code);
    return query.list();
}
