SSH分層設計

一、先來看代碼

---

1.準備好所需要的Jar包

antlr-2.7.6.jar 
aopalliance-1.0.jar 
c3p0-0.9.1.2.jar 
commons-collections-3.2.1.jar 
commons-logging.jar 
dom4j-1.6.1.jar 
ejb3-persistence.jar 
hibernate-jpa-2.0-api-1.0.0.Final.jar 
hibernate3.jar 
javassist-3.11.0.GA.jar 
jta-1.1.jar 
ojdbc6.jar 
slf4j-api-1.6.1.jar 
spring-aop-3.2.4.RELEASE.jar 
spring-beans-3.2.4.RELEASE.jar 
spring-context-3.2.4.RELEASE.jar 
spring-core-3.2.4.RELEASE.jar 
spring-expression-3.2.4.RELEASE.jar 
spring-jdbc-3.2.4.RELEASE.jar 
spring-orm-3.2.4.RELEASE.jar 
spring-tx-3.2.4.RELEASE.jar

2.準備數據庫

<code class="hljs sql has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><span class="hljs-operator" style="box-sizing: border-box;"><span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">create</span> <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">table</span> USER_INFO(

3.配置Spring配置文件

<code class="hljs applescript has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><?xml <span class="hljs-property" style="box-sizing: border-box;">version</span>=<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"1.0"</span> encoding=<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"UTF-8"</span>?>

二 、原理分析與實際應用

這種封裝的好處能夠大大的解決了Dao層代碼的重複性。因爲在Dao層中基本都是增刪改查的操作。所以代碼重複性很高。通過繼承和泛型的應用來實現一勞永逸的方法
