第一阶段:
1、用PowerDesign建数据模型,并导出SQL文件;
2、将SQL文件导入到MySQL客户端,建立表格;
MySQL数据远程访问:GRANT ALL PRIVILEGES ON . TO ‘root’@’%’IDENTIFIED BY ‘mypassword’ WITH GRANT OPTION;
如果是固定IP:grant all privileges on . to ‘root’@’192.168.41.100’identified by ‘123456’ with grant option;
//推送设置到内存或重启服务器也行
mysql>FLUSH PRIVILEGES
3、使用MyBatis框架,搭建DAO层:——————————-Mybatis—————————————
1)数据库连接的信息:驱动类、连接地址、用户名、密码
2)targetPackage=”com.softjx.model”
3)把表名与类名对应
4)运行GeneratorSqlmap.java生成dao和model
第二阶段:
1、在MyEclipse上新建一个Web项目,并导入ssm所需的jar包,放在WEB-INF/lib目录下;
2、将第一阶段通过Mybatis框架生成的model和dao复制到当前项目;—————–Dao层—————-
3、搭建Service层:建com.softjx.service与com.softjx,service,impl包;————-spring层—————
4、将需要相关的配置文件
(mybatisconfig.xml,dbconfig.properties,applicationContext.xml,log4j.properties)放到src目录下;
1)修改dbconfig.properties文件,ip,数据库,用户名,密码
2)修改applicationContext.xml中的包名,目录名
5、在com.softjx.service包中写接口,在com.softjx.service.impl写接口的实现。
注意:com.softjx.service.impl写接口的实现,
@Service(“studentService”)
@Transactional
类中注入
@Autowired
private StudentMapper studentMapper;
7.单元测试:
要注意mysql数据库中主键要自增,这一步要我们去mysql中设置。
studentService = (StudentService) context.getBean(“studentService”);
这个”studentService”是从@Service(“studentService”)
第三阶段:
1、修改WebRoot目录下的web.xml如下:
1
2 <web-app version="2.5"
3 xmlns="http://java.sun.com/xml/ns/javaee"
4 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
5 xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
6 http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

2、在src目录下建立springmvc.xml文件,文件内容如下:———-SpringMVC层—————-
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
