Spring MVC 3中关于url-pattern设成"/"后，资源访问问题

2011-11-28T01:52:00Z

SpringMVC3中关于url-pattern设成"/"后，CSS等资源的访问会报错：No mapping found for HTTP request with URI。

解决办法是将资源类文件夹放到resources目录中，然后在 servlet-context.xml中添加

xmlns:mvc="http://www.springframework.org/schema/mvc"

<resources mapping="/resources/**" location="/resources/" />

运行服务输出：

INFO : org.springframework.web.servlet.handler.SimpleUrlHandlerMapping - Mapped URL path [/resources/**] onto handler 'org.springframework.web.servlet.resource.ResourceHttpRequestHandler#0'

ODI调用必须使用代理才能访问的web service

2011-11-09T07:20:00Z

这个web service的服务器在防火墙内，通过端口映射的方式将端口映射为8080，实际服务器的端口为80.结果，访问通过wsdl时没有任何问题，但是wsdl中描述的服务地址仍然是80端口，所以调用此web service时需要将8080这个地址作为代理传入才能正常调用。在使用odi调用时需要时需要修改 odiparams.bat设置jvm运行参数。注意一下放置的位置。set ODI_ADDITIONAL_JAVA_OPTIONS="-Dhttp.proxyHost=finance.sysu.edu.cn" "-Dhttp.proxyPort=8800"

Android 给自己的类加个事件

2011-01-04T07:48:00Z

Android 给自己的类加个事件

1、定义一个接口

public abstract interface ISpriteAction {
    public interface OnClickListener {
        void onClick(Sprite v);
    }
}

2、给你的类定义事件

private ISpriteAction.OnClickListener onClickListener = null;

    public void setOnClickListener(ISpriteAction.OnClickListener listener){
        this.onClickListener = listener;
    }

触发事件

if(onClickListener != null) onClickListener.onClick(this);

3、设置事件处理代码

   @Override
   public void onClick(Sprite v) {
