javaDAO层获取以及使用

 private DataSource ds;
 private JdbcTemplate jdbc;
 
 public DataSource getDs() {
  return ds;
 }

 @Override
 public void setDataSource(DataSource ds) {
  this.ds = ds;
  this.jdbc = new JdbcTemplate(ds);
 }

 @Override
 public void create(String name, String password) {
 String sql = "insert into t_user (username, password) values (?, ?)";    
 jdbc.update( sql, name, password);
  System.out.println("Created Record Name = " + name + " Age = " + password);
 }
