Spring RowMapper callback Interface and QUERYFOR series summary

public void Queryfor () throws Exception {

StringBuilder sql=new StringBuilder ()

. Append ("Select Pid,pname,psex,pnationality,phobby,pdescription from where pid=?")

;

Object args[]={12};

Person p= () this.getjdbctemplate (). queryForObject (

Sql.tostring (),

Args

New RowMapper () {

Public Object Maprow (ResultSet rs, int arg1) throws SQLException {

Person P=new person ();

P.setpid (Rs.getint (1));

P.setpname (rs.getstring (2));

P.setpsex (Rs.getstring (3));

P.setpnationality (Rs.getstring (4));

P.setphobby (Rs.getstring (5));

P.setpdescription (rs.getstring (6));

return p;

}

}

);

System.out.println (P.getpid ());

System.out.println (P.getpname ());

}

Note: Spring's JDBC template provides a Queryfor series of methods:

queryForList (String sql,object args[],class ElementType)

Query for question mark in Object Args[]:sql statement

Class ElementType can check a column of multiple records the type of this column can be defined by itself as: String.class

queryForObject (String sql,class requiredtype) can query only one column of a single record
