/**
* SpringMVC HelloWorld
*
* 1、在web.xml中配置dispatcherservlet(如果eclipse中配置了spring插件可以用alt+/進行快速配置)
* 2、在spring-mvc.xml中配置InternalResourceViewResolver的bean
* 配置前序和後續
* ============================================================
* 3、使用requestmapping配置路徑
* 格式爲 prefix+requestmapping返回的路徑+suffix
* 其中requestmapping可以修飾在類上面
*
* 4、使用method指定請求方式:get、post、put、delete
* 5、指定params 則必須帶有指定參數,並且必須滿足參數條件,才能訪問函數,不滿足則報404,可以指定簡單表達式
* 6、指定headers,與指定params一樣,必須滿足表達式才能訪問方法,不滿足則報404
* ============================================================
*
* 7、配置ant方式訪問 參考sayhello2方法
* 在requestmapping中配置
* /*/方法名 則訪問時,可以用任意字符 訪問例如:http://127.0.0.1:8080/24SpringMVC01/Test/asdfasdf/sayHello2
* /**/方法名 如果兩個*號,代表任意路徑
*
* 8、@PathVariable 參考sayHello3方法
* /sayHello3/{xxx} 然後使用註解 @PathVariable(value="xxx") 類型 參數名
* 例如:http://127.0.0.1:8080/24SpringMVC01/Test/sayHello3/1/2
*
* @return
