題外話
這幾天要要寫項目了,Springmvc要先放下了,等放假在學,這幾天認真寫項目,實戰!
正文
web.xml與springmvc-servlet.xml兩個配置文件與上一篇一樣
.java

@Controller
@RequestMapping("/test")
// 相似於命名空間,唯一標識一個Controller,防止名稱重複
public class TestAnnController {
/**
* desc 參數列表中直接定義PrintWriter,來往頁面寫內容

*/

String result = "hello" + name;
out.print(result);
}
/**
