How-to-bind-String-to-java.sql.Timestamp

http://forum.springsource.org/showthread.php?48979-How-to-bind-String-to-java.sql.Timestamp

java.sql.TimeStamp is derived from java.util.Date. It shouldn't be hard to figure out how to handle that in the persistence layer- in fact I'm willing to bet that some persistence tools can handle that conversion automatically.

In regard to your command object, however, you have a tougher problem using TimeStamp. I'll explain why.

As I noted, TimeStamp is derived from java.util.Date. Spring has an out-of-the-box CustomDateEditor property editor that does conversions from Strings (like on a form filled out by a user) to java.util.Date. It also converts from java.util.Date back to String when a BindingResult is being used to re-populate form fields because the submission failed validation.

Now, for the CustomDateEditor to take the Date it has converted your String to and "jam" it into a TimeStamp field is not possible because it requires an explicit downcast. Spring does no such thing on your behalf. In fact- off the top of my head, I don't think such a downcast is even legal in Java- meaning you'd get an exception.

Do you see why I'm recommending going back to java.util.Date? It's the standard class used for transporting date (and time) information.

If you're really gung-ho about sticking with java.sql.TimeStamp, however, your next best bet is to create your own CustomTimeStampEditor. Basically crack open and copy the code for Spring's CustomeDateEditor and then modify it to suit TimeStamp.

Spring事务管理与异常处理注意事项

任何RuntimeException 将触发事务回滚，但是任何checked Exception 将不触发事务回滚

在dao 、servcie层都不要try catch，即使try catch 也要在catch中throw ServiceException供controler捕获

在controler中处理异常，所有catch都要ServiceException(自定义异常类继承于RuntimeException)

参考：http://www.iteye.com/topic/34867

@InitBinder 日期转换

@Controller
public class AbstractController {
   private String message;

    public String getMessage() {
       return message;
   }

   public void setMessage(String message) {
       this.message = message;
   }

   @InitBinder
    protected void initBinder(WebDataBinder binder) {
        binder.registerCustomEditor(Integer.class, null,
                                    new CustomNumberEditor(Integer.class, null, true));
        binder.registerCustomEditor(Long.class, null,
                                    new CustomNumberEditor(Long.class, null, true));
        binder.registerCustomEditor(byte[].class,
                                    new ByteArrayMultipartFileEditor());
        binder.registerCustomEditor(Date.class,new PropertyEditorSupport() {
        public void setAsText(String value) {
            try {
                setValue(new SimpleDateFormat(Constants.DATE_FORMAT).parse(value));
            } catch(ParseException e) {
                setValue(null);
            }
        }

        public String getAsText() {
            return new SimpleDateFormat(Constants.DATE_FORMAT).format((Date) getValue());
        }

    });
    }

}

自定义异常处理类

packagecom.capinfo.webapp.handler;

importorg.apache.commons.logging.Log;

importorg.apache.commons.logging.LogFactory;

importorg.springframework.web.servlet.HandlerExceptionResolver;

importorg.springframework.web.servlet.ModelAndView;

importjavax.servlet.http.HttpServletRequest;

importjavax.servlet.http.HttpServletResponse;

importjava.util.HashMap;

importjava.util.Map;

/**

public classMyHandlerExceptionResolver implements HandlerExceptionResolver {

private Log log =LogFactory.getLog(getClass());

public ModelAndViewresolveException(HttpServletRequest request,

HttpServletResponse httpServletResponse,

Object o, Exception ex) {

log.warn("Handle exception: "+ ex.getClass().getName());

Map model = newHashMap();

model.put("ex",ex.getClass().getSimpleName());

model.put("error",ex.getMessage());

return newModelAndView("error", model);

}

Jsp：error.jsp

<%@page language="java" pageEncoding="UTF-8"contentType="text/html;charset=UTF-8" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"

url-pattern问题

spring用到forward("/WEB-INF/jsp/*.jsp")
而forward当然是又要经过web.xml的映射的，
然后，在URL匹配时，
<url-pattern> / </url-pattern> 不会匹配到*.jsp，不会进入spring的DispatcherServlet类
<url-pattern> /* </url-pattern> 会匹配*.jsp，导致进入spring的DispatcherServlet 类，然后去寻找controller，接着找不到对应的controller所以报错。

总之，关于web.xml的url映射的小知识:
<url-pattern>/</url-pattern> 会匹配到/login这样的路径型url，不会匹配到模式为*.jsp这样的后缀型url
<url-pattern>/*</url-pattern> 会匹配所有url：路径型的和后缀型的url(包括/login,*.jsp,*.js和*.html等)

maven理解笔记

1、maven的生命周期 resources:resources--->compiler:compiler-->resources:testResources-->compiler:testCompile-->surefire:test-->jar:jar

2、maven的传递性依赖，在我们的项目中只需定义直接的依赖，maven会自动搜索并添加所有依赖并处理之间的冲突，在maven库中不仅有jar文件还有一个定义了依赖关系的pom文件，以实现依赖的查找。

3、依赖分为测试范围test 、编译范围compile、provided 范围（只在编译时使用，部署时已由容器提供，Servlet API 第三方开源实现Apache Geronimo org.apache.geronimo.specs）

4、配置jetty插件

<plugins>
<plugin>
<groupId>org.mortbay.jetty</groupId>
<artifactId>maven-jetty-plugin</artifactId>
</plugin>
</plugins>

5、maven 插件

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.5</source>
<target>1.5</target>
</configuration>

weblogic中部署多个使用了hibernate的应用 SessionFactory not available

一直以来我这边的工作就是在一个已有系统上克隆成一个又一个系统，超级无聊，以至于打断点跟踪时 eclipse经常犯晕跳到另外一个系统的同package同名的类中

今天又是两个及其相似的系统部署到了weblogic上，发现一个能访问数据库一个不行，一个行了另一个又不行

最后发现hibernate.cfg.xml中

<property name="hibernate.session_factory_name">hibernate_session</property>

两个应用中hibernate.session_factory_name值是一样的

改成不一样的值就OK了

但我的lib里面有这两个jar

而后发现删除javax.servlet.jar javax.servlet.jsp.jar 就不报错了

部署到GAE时中途退出后引起的问题

如果部署GAE时正在upload files时退出，下次部署时会报错

Another transaction by user is already in progress for this app and major version. That user can undo the transaction with appcfg.py's "rollback" command

找到eclipse中的GAE SDK目录

如：D:\eclipse\plugins\com.google.appengine.eclipse.sdkbundle.1.3.8_1.3.8.v201010161055\appengine-java-sdk-1.3.8\bin

执行命令

appcfg.cmd rollback 后面跟gae项目war所在目录

如 appcfg.cmd rollback D:/spring/eclipse_workspace/taobaoke/war

执行：

汉字按拼音排序

public int compare(String s1, String s2) {
return ((java.text.RuleBasedCollator)java.text.Collator.
getInstance(java.util.Locale.CHINA)).compare(s1, s2);
}

但是在GWT中不支持java.text...

改成这样

return javascriptSort(o1, o2);
}

在GAE上简单实现了一个淘宝客

在网上无意搜到一个用Ext实现的淘宝客，恩，咱用GWT做一个车轮

下了淘宝的 SDK for java就开干参考API文档按部就班

在淘宝的沙箱里测试，很顺利，乘胜前进，到正式环境下测试

问题来了

invalid signature

网上搜了一通，有说时间戳不对，果不其然，GAE使用的是标准时间，整整差了8小时，遂在获得的当前时间上加了8小时，OK

invalid signature 可能的另一个原因是APP_KEY 或 APP_SERCET不正确，仔细检查

调用 taobao.item.get

1 TaobaoClient client=new DefaultTaobaoClient(TaobaokeConstant.SANDBOX_URL, TaobaokeConstant.APP_KEY, TaobaokeConstant.APP_SERCET);
2 ItemcatsGetRequest req=new ItemcatsGetRequest();
3 java.util.Calendar c=java.util.Calendar.getInstance(TimeZone.getTimeZone("GMT+8"));
4 c.add(Calendar.HOUR, 8);
5 req.setTimestamp(c.getTime().getTime()) ;
6 req.setParentCid(new Long(0));
7 ItemcatsGetResponse response=client.execute(req);
8 return response.getItemCats();

调用 taobao.taobaoke.items.get 1 TaobaoClient client=new DefaultTaobaoClient(TaobaokeConstant.SANDBOX_URL, TaobaokeConstant.APP_KEY,TaobaokeConstant.APP_SERCET);
2 TaobaokeItemsGetRequest req=new TaobaokeItemsGetRequest();
3 req.setFields("num_iid,title,nick,pic_url,price,click_url,commission,commission_rate,commission_num,commission_volume,shop_click_url,seller_credit_score,item_location,volume,taobaoke_cat_click_url,keyword_click_url");
4 req.setCid(Long.parseLong(cid));

GWT POST 提交页面

将所有参数以&分隔放入builder.setRequestData中

01 RequestBuilder builder = new RequestBuilder(RequestBuilder.POST, BASIC_URL);
02 builder.setHeader("Content-Type","application/x-www-form-urlencoded; charset=utf-8");
03 builder.setRequestData("chartSWF=" + be.getSelectedItem().getType() + ".swf&chartId=" + be.getSelectedItem().getType() + "&strXML=" + generateXml(entry));
04 builder.setCallback(new RequestCallback(){
05      public void onError(Request request, Throwable exception) {
06          chart.removeAll();chart.addText("出错啦");
07      }
08      public void onResponseReceived(Request request, Response response) {
09      if(200 == response.getStatusCode()){
10          chart.removeAll();
11          chart.addText(response.getText());
12          chart.layout();
13      }else{
14          chart.removeAll();chart.addText("出错啦");
15      }
16      }
17 });
18
19      try {
20      builder.send();
21 } catch (RequestException e) {
22     e.printStackTrace();
23 }
