實習小結（五）--- SSM框架搭建（Maven項目）

以前分享了一個普通的SSM框架的搭建方法，感受仍是過於老套，如今都流行使用Maven來管理項目，在這分享一個使用Maven搭建的SSM（SpringMVC+Spring+MyBatis）

一、首先maven項目的最重要的部分是在pom.xml中添加依賴

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

二、在resources下存放一些配置文件信息，包括MyBatis中的實體類映射文件

（1）applicationContext.xml是Spring的配置文件，其中包括了鏈接數據庫，配置mybatis的sqlSessionFactory，dao接口，事務，以及Shiro，aop的配置

<?xml version="1.0" encoding="UTF-8"?>

（2）jdbc.properties和log4j.properties是鏈接數據庫的信息和打印日誌的信息

jdbc.properties

#jdbc.name=
jdbc.url=jdbc:mysql://localhost:3306/studentmanager?characterEncoding=utf8&useSSL=no
jdbc.username=root
jdbc.password=root

 

log4j.properties

log4j.rootLogger=DEBUG, Console  
  
#Console  
log4j.appender.Console=org.apache.log4j.ConsoleAppender  
log4j.appender.Console.layout=org.apache.log4j.PatternLayout  
log4j.appender.Console.layout.ConversionPattern=%d [%t] %-5p [%c] - %m%n  
  
log4j.logger.java.sql.ResultSet=INFO  
log4j.logger.org.apache=INFO  
log4j.logger.java.sql.Connection=DEBUG  
log4j.logger.java.sql.Statement=DEBUG  
log4j.logger.java.sql.PreparedStatement=DEBUG  

 

（3）mybatis-config.xml是MyBatis的配置文件

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
    <!-- 別名 -->
    <typeAliases>
        <package name="com.tm.entity"/>
    </typeAliases>
</configuration>

 

（4）spring-mvc.xml是SpringMVC的配置文件

<?xml version="1.0" encoding="UTF-8"?>    
<beans xmlns="http://www.springframework.org/schema/beans"

（5）最後是web.xml文件

SSM框架的配置文件就放在這裏，之後如有用到搭建環境的時候，直接能夠拿去使用。
