Spring 分页

JdbcTemplate 2 中分页查询简介。 一、第一种方法
// sqlFetchRows分页sql语句
// startRow 开始行
// currentRow 当前行
// pageSize页面大小
// 实体类rowMapper

JdbcTemplate.query(sqlFetchRows,args, new ResultSetExtractor() {  
       public Object extractData(ResultSet rs) throws SQLException,  
                DataAccessException {  
     
            final List result = fr.getResult();  
            int currentRow = 0;  
            while (rs.next() && currentRow < startRow + pageSize) {
                if (currentRow <= startRow) {
                result.add(rowMapper.mapRow(rs, currentRow));  
                }  
                currentRow++;  
            }
            return result;  
        }  
       });



二、第二种方法

String yoursql = "select * from XXX";
StringBuffer sqlQuery = new StringBuffer();
sqlQuery.append("select * from (select temp.*,rownum rownumber from (")
                 .append(yoursql)
                 .append("))");

    // objects 参数数组Object[]
   //总记录数
   int totalRows = jdbcTemplate.queryForInt(sqlCount.toString(), objects);
   //开始索引位置
   int startIndex = (currentPage - 1)*Constant.PAGESIZE;
   //最后一条记录的索引位置
   int lastIndex = 0;
   //总页数
   int totalPages = 0;
   if (totalRows % PAGESIZE == 0) {
    totalPages = totalRows / PAGESIZE;
   } else {
    totalPages = (totalRows / PAGESIZE) + 1;
   }
 
   if (totalRows < PAGESIZE){
    lastIndex = totalRows;
   } else if ((currentPage == totalPages && totalRows % PAGESIZE == 0) || currentPage < totalPages) {
    lastIndex = currentPage*PAGESIZE;
   } else if ((currentPage == totalPages && totalRows % PAGESIZE != 0)) {
    lastIndex = totalRows;
   }

   sqlQuery.append(") temp where ROWNUM <= ")
          .append(lastIndex)
          .append(" ) where rownumber > ")
          .append(startIndex);

   List list = this.jdbcTemplate.queryForList(sqlQuery.toString(), objects);
