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

        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>encoding</filter-name>
        <url-pattern>*.action</url-pattern>
    </filter-mapping>
    <!--配置SpringMVC前端控制器-->
    <servlet>
        <servlet-name>springmvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <!--初始化时加载配置文件-->
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath*:springmvc-config.xml</param-value>
        </init-param>
        <!--配置服务器启动时立即加载SpringMVC配置文件-->
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>springmvc</servlet-name>
        <url-pattern>*.action</url-pattern>
    </servlet-mapping>

    <!--系统默认页面-->
    <wel***e-file-list>
        <wel***e-file>index.jsp</wel***e-file>
    </wel***e-file-list>
</web-app>

此时配置文件基本完成
下面是项目的目录结构
