6_SSM

一. ssm整合

1.1 项目创建

1.1.1 创建Maven项目

• 创建一个普通的Maven-web项目,名称为ssm
• 记得勾选上Create from archetype然后选择后缀为maven-archetype-webapp的选项

1.1.2 导入依赖(pom.xml)

1.1.3 创建项目目录

• src/main/java下创建
• com.dz.pojo
• com.dz.dao
• com.dz.service
• com.dz.controller
• src/main/resources下创建
• jdbc.properties (数据库连接配置文件)
• log4j.properties (日志配置文件)
• mybatis-config.xml (MyBatis配置文件)
• applicationContext.xml (Spring配置文件,总)
• spring-dao.xml (Spring配置文件,子)
• spring-service.xml (Spring配置文件,子)
• spring-mvc.xml (Spring配置文件,子)
• src/main/webapp/WEB-INF下
• 新建jsp目录, 里面存放.jsp文件
• 已有的web.xml也要进行配置

2.1 配置文件

2.1.1 jdbc.properties

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/mybatis_db?useUnicode=true&useSSL=false&characterEncoding=UTF-8
jdbc.username=root
jdbc.password=8031

2.1.2 log4j.properties

log4j.rootLogger=DEBUG, stdout

log4j.logger.org.mybatis.example.BlogMapper=TRACE

log4j.appender.stdout=org.apache.log4j.ConsoleAppender

log4j.appender.stdout.layout=org.apache.log4j.PatternLayout

log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss,SSS} - %5p [%t] - %m%n

2.1.3 mybatis-config.xml

        <package name="com.dz.pojo"/>
