1.exception setting property value with CGLIB (set hibernate.cglib.use_reflection_optimizer=false for more info) setter of
又见这样的错误,原因是对于一些数字项由于从数据库里面取出的值为null

2.映射为bolean的字段,在建表时，如果没有设定字段的default值,会导致exception setting property value with CGLIB setter错误.设置好默认值问题就可以解决了



--------------------得到SPRING的BEAN-------------
1 .WebApplicationContextUtils     .getRequiredWebApplicationContext(servlet.getServletContext());  
public Object getBean(String name)  
   {  
       if (ctx == null)  
       {  
           ctx = WebApplicationContextUtils  
                 .getRequiredWebApplicationContext(servlet.getServletContext());  
       }  
       return ctx.getBean(name);  
   }

2. public static void main(final String[] args) throws Exception {
        ApplicationContext ctx = new ClassPathXmlApplicationContext("context.xml", Boot.class); //必需放在WEB-INF/lib/class下面
        FooService fooService = (FooService) ctx.getBean("fooService");
        fooService.insertFoo (new Foo());
    }


3. ApplicationContext ctx = new FileSystemXmlApplicationContext(new String[] { "src/cn/com/jbaptech/po/applicationContext.xml" });ctx.getBean("fooService");

-----------------------下载时，设置response的参数----------------------

response.setContentType("APPLICATION/OCTET-STREAM");

------------------------查找路径方法-----------------------------------
在类中: this.getClass().getClassLoader().getResource("/").getPath(); -- 返回 "工程/web-inf/classes"路径，可以把“/”替换成 ××.xml 找文件

--------------------------linux 乱改显卡型号后-------------------------
cd /etc/Xll

----------web 项目在 JAVA中获得SESSION (配DWR)------------------

WebContext webCtx = WebContextFactory.get();
User o = (User)webCtx.getSession().getAttribute(AppConstants.SESSION_USER);

It's easy to use DWR and Reverse Ajax from a thread outside of DWR. You can't use WebContext though because that's only of use to threads under the control of DWR.In place of WebContext, you should use ServerContext, which has many of the same operations
