Maven+SSM+oracle框架實現簡單的增刪改查

最下方是代碼但不建議直接使用，本身搭一下環境印象更加深入。

Spring介紹:

spring 使用基本的 JavaBean 來完成之前只可能由 EJB 完成的事情。然而， Spring的用途不只限於服務器端的開發。從簡單性、可測試性和鬆耦合的角度而言，任何Java 應用均可以從 Spring 中受益。 簡單來講， Spring 是一個輕量級的控制反轉（IoC ）和麪向切面（ AOP ）的容器框架。

SpringMVC介紹

Spring MVC 屬於 SpringFrameWork 的後續產品，已經融合在Spring Web Flow 裏面。 Spring MVC  分離了  控制器 、模型  對象 、分派器以及處理程序對象的角色，這種分離讓它們更容易進行定製。

MyBatis介紹

  MyBatis  本是  apache 的一個開源項目  iBatis , 2010 年這個項目由apache software foundation  遷移到了 google code ，而且更名爲 MyBatis  。MyBatis 是一個基於 Java 的  持久層 框架。 iBATIS 提供的  持久層 框架包括SQL Maps 和 Data Access Objects （ DAO ） MyBatis  消除了幾乎全部的 JDBC 代碼和參數的手工設置以及結果集的檢索。 MyBatis  使用簡單的  XML 或註解用於配置和原始映射，將接口和  Java  的 POJOs （ Plain Old Java Objects ，普通的  Java 對象）映射成數據庫中的記錄。

首先不是maven架構整合的  SSM 框架

 

建立數據庫、表  t_user   user_t【最下面有sql語句】

1.項目總體結構，上一篇已經介紹了搭建maven環境

2.Eclipse下建立Maven項目

 

這裏建立一個Maven project，上面的Maven Module是maven模塊化開發用到的，能夠理解爲子工程。

接着Next

 

 這裏選擇maven-archetype-webapp，建立一個maven-webapp樣例工程的意思

 

這裏因爲我已經建立了此項目，若是新建直接點擊finish

 

 

 

。因爲

 

 

 

此處groupid和artifactId被統稱爲「座標」是爲了保證項目惟一性而提出的.。org通常指一些組織機構，非盈利組織。我我的的項目通常喜歡用org。zch是我名字的縮寫。artifactId寫項目名稱就能夠了。

 

如今須要改一下項目的結構。由於maven項目是須要下列Source Folder文件夾的。

src/main/resources

src/main/java

src/test/resources

src/test/java

 

 

 

這裏提示沒有找到這幾個文件夾。先把它們remove掉。手動建立

 

 

 

OK，這就是maven項目的結構了，如今已經沒有報錯提示。提醒：此處建立的是Source Folder文件夾。不要建立成Folder。

下面再改一下輸出目錄，把下面的allow output folders for source folders勾上。

 

 

按上述步驟把那四個source folder改下輸出目錄。編譯的class就是輸出到對應的目錄下。

src/main/resources和src/main/java選擇classes。建立文件的輸出。

建立完以後引入所須要的jar包

 

配置文件更改。因爲maven沒有oracle的jar包因此要本身下載，個人工程裏有對應的jar包。
