🥭本文内容:SSM框架的整合使用,还有bootstrap等前端框架的简单使用,做一个简单的新闻管理系统
SSM整合
前言
在前文中,我们学完了
Spring
、SpringMVC
的内容,现在我们就将学过的内容做一个整合使用,做一个新闻管理系统。
系统功能需求
系统结构设计
本系统根据功能的不同,项目结构可以划分为以下几个层次:
- 持久对象层:由若干持久化类(实体类)组成。
- 数据访问层:曲若干DAO 接口和
mybatis
映射文件组成。接口的名称统一以DAO结尾,且MyBatis
的映射文件名称要与接口的名称相同。 - 业务逻辑层:该层由若干
Service
接口和实现类组成。在本系统中,业务逻辑层的接口统一使用Service结尾,共实现类名称统一在接口名后加Impl。该层主要用于实现系统的业务逻辑。 - Web表现层:该层主要包括
SpringMVC
中的Controller类和 JSP 页面。Controller 类主要负责拦截用户请求,并调用业务逻拜层中相应组件的业务逻輯方法来处理用户请求,然后将相应的结果返回给 JSP 页面。
数据库设计
数据库设计比较简单,这里我直接放建表语句
create database news;
use news;
#创建一个角色表
create table t_role(
roleId int primary key,
roleName varchar(20)
);
#插入两条数据
insert into t_role values(1,'管理员'),(2,'信息员');
#创建一个名为t_user的表
create table t_user(
`userId` int primary key AUTO_INCREMENT,
`userName` varchar(20),
`loginName` varchar(20),
`password` varchar(20),
`tel` varchar(50),
`registerTime` datetime,
`status` char(1),
`roleId` int,
foreign key (roleId) references t_role(roleId)
);
#插入一条数据
insert into t_user(userName, loginName, `password`, `status`, roleId) values("至简","admin","abc123456","2",1);
#创建一个名称为t_category的表
create table t_category(
categoryId int primary key,
categoryName varchar(20)
);
#插入四条数据
insert into t_category values(1,"今日头条"),(2,"综合资讯"),(3,"国内新闻"),(4,"国际新闻");
#创建一个名为t_news的表
create table t_news(
newsId int primary key AUTO_INCREMENT,
title varchar(60),
contentTitle varchar(120),
titlePicUrl varchar(120),
content TEXT,
contentAbstract varchar(300),
keywords varchar(100),
author varchar(30),
publishTime dateTime,
clicks int,
publishStatus char(1),
categoryId int,
userId int,
foreign key (categoryId) references t_category(categoryId),
foreign key (userId) references t_user(userId)
);
整合环境搭建
创建一个maven项目
添加Web整合(在Project structure里面的Facets中)
编辑pom.xml

结语
以上就是今天要讲的内容,主要是SSM的整合使用,因为代码太多了,不好放在这上面,所以大家可以关注公众号 回复 新闻就可以获取代码哟。
如果各位大哥大姐对我所写的内容觉得还行的话,希望可以点个关注,点个收藏,您的支持就是我最大的动力,非常感谢您的阅读(❁´◡`❁)
