这是一个关于dwr和使用ext进行编辑的例子,ext初搞，头大.感觉ext学习起来有些麻烦
bean类
package table;
import java.util.Date;
public class ExtBean {
private String common;
private String light;
private float price; // automatic date conversions
private Date availDate;
private boolean indoor;
public ExtBean() {
}
public ExtBean(String common, String light, float price, Date availDate, boolean indoor) {
this.common = common;
this.light = light;
this.price = price;
this.availDate = availDate;
this.indoor = indoor;
}
public Date getAvailDate() {
return availDate;
}
public void setAvailDate(Date availDate) {
this.availDate = availDate;
}
public String getCommon() {
return common;
}
public void setCommon(String common) {
this.common = common;
}
public boolean isIndoor() {
return indoor;
}
public void setIndoor(boolean indoor) {
this.indoor = indoor;
}
public float getPrice() {
return price;
}
public void setPrice(float price) {
this.price = price;
}
public String getLight() {
return light;
}
public void setLight(String light) {
this.light = light;
}
}
dwr处理类:
package table;
import java.util.ArrayList;
import java.util.Date;
import java.util.Iterator;
import java.util.List;
import org.apache.log4j.Logger;
public class ExtBeanModel {
private static Logger logger = Logger.getLogger(ExtBeanModel.class.getName());
public ExtBeanModel() {
// TODO Auto-generated constructor stub
}
public String save(List<ExtBean> extBeans) throws Exception{
logger.debug("start");
for(Iterator<ExtBean> it = extBeans.iterator(); it.hasNext();){
ExtBean extBean = it.next();
System.out.println(extBean.getCommon() + " "
+ extBean.getLight()+" "
+ extBean.getAvailDate()+ " " + extBean.getPrice() + " "
+ extBean.isIndoor());
}
return "ok";
}
public List<ExtBean> getExtBeans(){
List<ExtBean> extList = new ArrayList<ExtBean>();
ExtBean ext1 = new ExtBean("Erythronium","测试1",9.6F,new Date(),false);
ExtBean ext2 = new ExtBean("Erythronium2","测试2",9.6F,new Date(),true);
extList.add(ext1);
extList.add(ext2);
return extList;
}
}
