jdbcTemplate查询

    //       简单sql

 String sql = " select w.id,w.title,w.menucode,w.pid,w.pname,w.createdate,w.content,w.status,w.imagename " +

    " from mss_worknewcontent w " +

    " where 1=1 and w.status = 1 and w.menucode = 'fengguang' and w.pid = '"+id+"' ";

//    jdbcTemplate模板查询获得map list

List<Map<String,Object>> list = jdbcTemplate.queryForList(sql);

//在把list封装成某对象的形式，这样的操做就是避免了实体类在与操做表那些复杂关系
