使用Spring_JDBCTemplate

org.springframework.jdbc.core.PreparedStatementCreator 返回预编译SQL   不能于Object[]一起用
public PreparedStatement createPreparedStatement(Connection con) throws SQLException {
  return con.prepareStatement(sql);
}
1.增删改
org.springframework.jdbc.core.JdbcTemplate   类(必须指定数据源dataSource)
template.update("insert into web_person values(?,?,?)",Object[]);
  或
template.update("insert into web_person values(?,?,?)",new PreparedStatementSetter(){ 匿名内部类只能访问外部最终局部变量
  public void setValues(PreparedStatement ps) throws SQLException {
   ps.setInt(index++,3);
});
org.springframework.jdbc.core.PreparedStatementSetter 接口处理预编译SQL
public void setValues(PreparedStatement ps) throws SQLException {
  ps.setInt(index++,3);
}
2.查询JdbcTemplate.query(String,[Object[]/PreparedStatementSetter],RowMapper/RowCallbackHandler)
org.springframework.jdbc.core.RowMapper   记录映射接口  处理结果集
public Object mapRow(ResultSet rs, int arg1) throws SQLException {   int表当前行数
   person.setId(rs.getInt("id"));
}
List template.query("select * from web_person where id=?",Object[],RowMapper);

org.springframework.jdbc.core.RowCallbackHandler  记录回调管理器接口处理结果集
template.query("select * from web_person where id=?",Object[],new RowCallbackHandler(){
  public void processRow(ResultSet rs) throws SQLException {
   person.setId(rs.getInt("id"));
});
