Maven创建Web项目、、、整合SSM框架

标签：styles   valueof   字符   null   导入   center   tom   软件测试   mon   

自己接触ssm框架有一段时间了，从最早的接触新版ITOO项目的（SSM/H+Dobbu zk），再到自己近期来学习到的《淘淘商城》一个ssm框架的电商项目。用过，但是还真的没有自己搭建过，一直都是用别人搭建好的。所以，从网上找了一些材料，结合自己来解决过程中的一些问题，使自己对ssm框架理解更加深了，不为分享，只是总结一下，下次有机会再搭建的时候，直接看自己的博客，省得找了！

一、准备环境：

maven：apache-maven-3.2.3

jdk：jdk1.8.0_25

tomcat：tomcat-6.0.37

二、配置Maven、jdk

1、Window——>Preferences——>Maven——>设置自己的Settings

2、Window——>Preferences——>Java——>Installed JREs——>Add

配置好maven之后，就可以在本地设置好的地方看到对应的Maven文件了，还有包含resp文件夹

三、新建Maven项目：

1、右击——>New（或者是File——>New）——>other——>Maven——>Maven Project——>Next

2、这时候，我们就成功创建出一个Maven项目了，项目结构如下图：

3、右击项目，选择Properties进行一些配置：

       到这里，我们的Maven项目就建好了，接下来，我们来整合搭建SSM（spring MVC + Spring + Mybatis）

首先我们来配置一些整合框架所必须要的jar包，也就是来配置我们的pom文件，然后直接alt+f5，保存后，就会自动下载，存放在之前配置好的本地maven仓库中。

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

[html] view plain copy

 

 print?

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"

24.         
25.     <!-- 导入数据库配置 -->    
26.     <import resource="spring-tx.xml"/>    
27.         
28. </beans>    

配置数据库连接池：jdbc.properties

[html] view plain copy

 

 print?

1. driver=com.mysql.jdbc.Driver    
2. url=jdbc:mysql://localhost:3306/maven_ssm    
3. username=root    
4. password=root    
5. #定义初始连接数    
6. initialSize=0    
7. #定义最大连接数    
8. maxActive=20    
9. #定义最大空闲    
10. maxIdle=20    
11. #定义最小空闲    
12. minIdle=1    
13. #定义最长等待时间    
14. maxWait=60000    

配置日志：log4j.properties

[html] view plain copy

 

 print?

1. #定义LOG输出级别    
2. log4j.rootLogger=INFO,Console,File    
3. #定义日志输出目的地为控制台    
4. log4j.appender.Console=org.apache.log4j.ConsoleAppender    
5. log4j.appender.Console.Target=System.out    
6. #可以灵活地指定日志输出格式，下面一行是指定具体的格式    
7. log4j.appender.Console.layout = org.apache.log4j.PatternLayout    
8. log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n    
9.     
10. #文件大小到达指定尺寸的时候产生一个新的文件    
11. log4j.appender.File = org.apache.log4j.RollingFileAppender    
12. #指定输出目录    
13. log4j.appender.File.File = logs/ssm.log    
14. #定义文件最大大小    
15. log4j.appender.File.MaxFileSize = 10MB    
16. # 输出所以日志，如果换成DEBUG表示输出DEBUG以上级别日志    
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    

配置我们的ioc注入：spring-dao.xml

到这里，我们的ssm框架就完成了，下面，我们来个实现：

在src/main/java下分别添加我们的dao包，service包，还有controller包.包里面添加相应的类，效果图如下：

UserController.java:

userinfo.jsp:

31. </html>     

哦,忘记配置tomcat，配置一下tomcat，然后部署发布项目，进行测试

到此，框架成

Maven创建Web项目、、、整合SSM框架
