本身接觸ssm框架有一段時間了，從最先的接觸新版ITOO項目的（SSM/H+Dobbu zk），再到本身近期來學習到的《淘淘商城》一個ssm框架的電商項目。用過，可是還真的沒有本身搭建過，一直都是用別人搭建好的。因此，從網上找了一些材料，結合本身來解決過程當中的一些問題，使本身對ssm框架理解更加深了，不爲分享，只是總結一下，下次有機會再搭建的時候，直接看本身的博客，免得找了！css

 

1、準備環境：html

maven：apache-maven-3.2.3java

jdk：jdk1.8.0_25mysql

tomcat：tomcat-6.0.37web

2、配置Maven、jdkspring

一、Window——>Preferences——>Maven——>設置本身的Settingssql

二、Window——>Preferences——>Java——>Installed JREs——>Add數據庫

配置好maven以後，就能夠在本地設置好的地方看到對應的Maven文件了，還有包含resp文件夾express

 

3、新建Maven項目：apache

一、右擊——>New（或者是File——>New）——>other——>Maven——>Maven Project——>Next

 

 

二、這時候，咱們就成功建立出一個Maven項目了，項目結構以下圖：

 

三、右擊項目，選擇Properties進行一些配置：

 

       到這裏，咱們的Maven項目就建好了，接下來，咱們來整合搭建SSM（spring MVC + Spring + Mybatis）

首先咱們來配置一些整合框架所必需要的jar包，也就是來配置咱們的pom文件，而後直接alt+f5，保存後，就會自動下載，存放在以前配置好的本地maven倉庫中。

二、在src/main/resources下添加配置文件：applicationContext.xml:

 

view plain  copy  print?在CODE上查看代碼片派生到個人代碼片
  1. <?xml version="1.0" encoding="UTF-8"?>    
  2. <beans xmlns="http://www.springframework.org/schema/beans"    
  3.     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"    
  4.     xmlns:context="http://www.springframework.org/schema/context"    
  5.     xmlns:mvc="http://www.springframework.org/schema/mvc"    
  6.     xsi:schemaLocation="http://www.springframework.org/schema/beans      
  7.                         http://www.springframework.org/schema/beans/spring-beans-3.1.xsd      
  8.                         http://www.springframework.org/schema/context      
  9.                         http://www.springframework.org/schema/context/spring-context-3.1.xsd      
  10.                         http://www.springframework.org/schema/mvc      
  11.                         http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">    
  12.                             
  13.     <!-- 使用註解式注入 -->    
  14.     <context:annotation-config />    
  15.         
  16.     <!-- 自動掃描 -->    
  17.     <context:component-scan base-package="com.ssm" />    
  18.         
  19.     <!-- 導入DAO配置 -->    
  20.     <import resource="spring-dao.xml"/>    
  21.         
  22.     <!-- 導入數據庫配置 -->    
  23.     <import resource="spring-db.xml"/>    
  24.         
  25.     <!-- 導入數據庫配置 -->    
  26.     <import resource="spring-tx.xml"/>    
  27.         
  28. </beans>    

 

 

配置數據庫鏈接池：jdbc.properties

 

 

view plain  copy  print?在CODE上查看代碼片派生到個人代碼片
  1. driver=com.mysql.jdbc.Driver    
  2. url=jdbc:mysql://localhost:3306/maven_ssm    
  3. username=root    
  4. password=root    
  5. #定義初始鏈接數    
  6. initialSize=0    
  7. #定義最大鏈接數    
  8. maxActive=20    
  9. #定義最大空閒    
  10. maxIdle=20    
  11. #定義最小空閒    
  12. minIdle=1    
  13. #定義最長等待時間    
  14. maxWait=60000    

 

 

配置日誌：log4j.properties

 

view plain  copy  print?在CODE上查看代碼片派生到個人代碼片
  1. #定義LOG輸出級別    
  2. log4j.rootLogger=INFO,Console,File    
  3. #定義日誌輸出目的地爲控制檯    
  4. log4j.appender.Console=org.apache.log4j.ConsoleAppender    
  5. log4j.appender.Console.Target=System.out    
  6. #能夠靈活地指定日誌輸出格式，下面一行是指定具體的格式    
  7. log4j.appender.Console.layout = org.apache.log4j.PatternLayout    
  8. log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n    
  9.     
  10. #文件大小到達指定尺寸的時候產生一個新的文件    
  11. log4j.appender.File = org.apache.log4j.RollingFileAppender    
  12. #指定輸出目錄    
  13. log4j.appender.File.File = logs/ssm.log    
  14. #定義文件最大大小    
  15. log4j.appender.File.MaxFileSize = 10MB    
  16. # 輸出因此日誌，若是換成DEBUG表示輸出DEBUG以上級別日誌    
  17. log4j.appender.File.Threshold = ALL    
  18. log4j.appender.File.layout = org.apache.log4j.PatternLayout    
  19. log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n    


配置咱們的ioc注入：spring-dao.xml

  21.                             
  22. </beans>    

 

 

spring-db.xml

配置spring的事務管理器：spring-tx.xml

接下來，咱們來整合spring mvc：spring-mvc.xml:

到這裏，咱們的ssm框架就完成了，下面，咱們來個實現：

在src/main/java下分別添加咱們的dao包，service包，還有controller包.包裏面添加相應的類，效果圖以下：

 

 

UserController.java:
