javaweb各种框架组合案例(三)：maven+spring+springMVC+hibernate
生活随笔
收集整理的這篇文章主要介紹了
javaweb各种框架组合案例(三)：maven+spring+springMVC+hibernate
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
1.hibernate譯為“越冬”，指的是給java程序員帶來春天，因為java程序員無需再關心各種sql了；
2.hibernate通過java類生成數據庫表，通過操作對象來映射成SQL；
3.hibernate是真正意義上的ORM框架，因為他實現了對象（Object）---->關系（Relation）的映射（Mapping）；
4.maven項目整體包結構（報錯是eclipse發神經，不用管）
因為hibernate可以根據類生成表，所以只需創建數據庫即可;
create database ssh;?
該案例實現了一個用戶擁有多部手機的關系

?
11.jsp頁面測試登錄
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <!doctype html> <html> <head> <meta charset="UTF-8"> <title>Insert title here</title> </head> <body><form action="user/login" method="post"><div><label>username</label><input type="text" name="username"/></div><div><label>password</label><input type="password" name="password"/></div><div><input type="submit" value="登錄"></div></form> </body> </html> index.jsp <%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <!doctype html> <html> <head> <meta charset="UTF-8"> <title></title> </head> <body>username=${user} </body> </html> result.jsp?
?
12.項目啟動后，你會發現你的ssh數據庫中多了兩張表User和Phone，自己在插入幾條數據
user表? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?phone表
? ? ??
?
13.測試
index.jsp表單中輸入1001和123
result.jsp

14.注意點：我個人覺得ssh框架坑實在是多，我在搭建的過程中出現了各種各樣的問題，不過最惡心的問題是spring和hibernate存在版本不兼容問題，一開始使用的是spring5+hibernate5，發現報錯，就將hibernate5換成4（應該沒問題了吧），結果還是報錯，折騰半天，發現雖然Pom版本雖然換成4，但是之前dao層用到的HibernateDaoSupport和spring-context.xml配置中SessionFactory還是5的版本，誒，智障問題。
