1. Mybatis層編寫
1、在 resources 目錄下新建數據庫配置文件 database.properties

jdbc.driver=com.mysql.jdbc.Driver# 如果是使用 MySQL8.0+ 那么還需要增加一個時區的配置; serverTimezone=Asia/Shanghaijdbc.url=jdbc:mysql://localhost:3306/ssmbuild?useSSL=true&useUnicode=true&characterEncoding=utf8jdbc.username=rootjdbc.password=123456 |
2、在 resources 目錄下創建Mybatis配置文件 mybatis-config.xml

<?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> <!--配置數據源, 交給Spring--> <!--配置log--> <settings> <!--STDOUT_LOGGING: 標準的日志工廠實現--> <setting name="logImpl" value="STDOUT_LOGGING"/> </settings> <!--配置別名--> <typeAliases> <package name="com.pro.pojo"/> </typeAliases> <!--綁定Mapper--> <mappers> <mapper class="com.pro.dao.BooksMapper"/> </mappers></configuration> |
2. Spring層編寫
1. Spring整合Mybatis
配置Spring整合MyBatis，這里數據源使用c3p0連接池；
編寫Spring整合Mybatis的相關的配置文件；在 resources 目錄下創建 spring-dao.xml
注意：這里要引入上面Mybatis層的兩個配置文件，配置文件的名稱不要寫錯

2. Spring整合service
將業務層的類注入到Spring中，在 resources 目錄下創建 spring-service.xml

3. SpringMVC層編寫
1. 編寫web.xml
修改 WEB-INF 下的 web.xml 文件
這里引入Spring整合的配置文件 applicationContext.xml
