The content of Helloform.java is as follows:

The content of Helloform.java is as follows:

Package com.ben.test.struts;

Public string getname () {

Return name;}

Public void setname (String name) {

THIS.NAME = Name;

}

Public ActionerRors Validate (ActionMapping Mapping, httpservletRequest Request) {

ActionerroS Errors = new actionerrors ();

// Error handle, add yourself

Return Errors;

}

}

The content of HelloAction.java is as follows:

The content of HelloAction.java is as follows:

HTTPSERVLETREQUEST REQUEST,

HttpservletResponse response) throws exception {

Helloform Helloform = (Helloform) Form;

String name = helloform.getname ();

INT ID = 0;

DataSource DataSource = (DataSource) servlet.getServletContext (). GetAttribute (

"org.apache.struts.action.data_source");

Try {

Try {

Connection conn = DataSource.getConnection ();

Statement Stmt = conn.createstatement ();

ResultSet RS = Stmt.executeQuery ("Select * from name " ");

While (rs.next ()) {

ID = rs.getint ("id");

}

Rs.close ();

CONN.CLOSE ();

}

Catch (SQLException E) {

Throw New Sqlexception ("Database Error");

}

Request.setttribute ("Name", New Integer (ID));

Return mapping.findforward ("Sayhello");

}

}

The code is created in accordance with the data source configured in Struts-Config, and then obtain the ID corresponding to the Name in accordance with the NameTable of the Name to the database, then let the ID value of the request to Sayello More struts-config configuration, Sayhello corresponds to this file
