也就是不寫dwr.xml，用annotation的方式一樣可以
以前端取資料庫的 method為例，改成annotation
※web.xml
<servlet> <servlet-name>dwr-invoker</servlet-name> <servlet-class>org.directwebremoting.servlet.DwrServlet</servlet-class> <init-param> <param-name>debug</param-name> <param-value>true</param-value> </init-param> <init-param> <param-name>classes</param-name> <param-value> dao.impl.DaoImpl, vo.Chess </param-value> </init-param> </servlet> <servlet-mapping> <servlet-name>dwr-invoker</servlet-name> <url-pattern>/dwr/*</url-pattern> </servlet-mapping>
※只有增加classes的init-param部分
※這裡增加impl和java bean，如果不寫會在執行時出「DefaultConverterManager convertOutbound」的錯
※impl
@RemoteProxy(name="dao")
public class DaoImpl implements Idao {
@Override
@RemoteMethod
public boolean save(Chess chess) {
System.out.println("新增成功！");
return true;
}
@Override
@RemoteMethod
public Chess getChess(Long id) {
Chess chess = new Chess();
chess.setId(id);
chess.setName("象棋");
chess.setDate(new Date());
return chess;
}
@Override
@RemoteMethod
public List<Chess> getAllChess() {
List<Chess> chList = new ArrayList<>();
for (long i = 1; i < 4; i++) {
Chess chess = new Chess();
chess.setId(i);
if (i == 1) {
chess.setName("象棋");
} else if (i == 2) {
chess.setName("跳棋");
} else if (i == 3) {
chess.setName("五子棋");
}
try {
chess.setDate(new SimpleDateFormat("yyyyMMdd").parse("2010061" + i));
} catch (ParseException e) {
e.printStackTrace();
}
chList.add(chess);
}
return chList;
}
}
※class上多個@RemoteProxy，其他方法上面都是@RemoteMethod
※vo
@DataTransferObject
public class Chess{
@RemoteProperty
private Long id;
@RemoteProperty
private String name;
@RemoteProperty
private Date date;
// setter/getter...
}
※java bean要轉換要使用@DataTransferObject，而欄位用@RemoteProperty
