一、配置SSM框架
创建Maven项目，勾选Create from archetype后，选择maven-archetype-webapp
输入项目名并选择保存位置
继续下一步，使用本地的setting文件和jar包地址
点击finish后项目创建完成，下面开始正式配置
首先要配置文件的目录结构，配置完成后的目录结构如图所示：
注意:我在建包时遇到了无法在com包下建立它的下级包的情况，在下图所示位置取消勾选compact middle packlages选项即可
修改pom.xml文件，导入需要的包

</project>
修改完成后，在项目名处右击，选择Maven-Reimport即可完成引入
下一步，在resource目录进行配置文件的添加，共4个文件
（1）连接数据库配置信息文件：db.properties
druid.driver=com.mysql.jdbc.Driver druid.url=jdbc:mysql://localhost:3306/all_db?characterEncoding=utf-8 druid.username=root druid.password=Guozhaojie610
（2）Mybatis配置文件：SqlMapConfig.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>
<!-- 给实体类起别名 -->
<typeAliases >
<package name="com.xiao.pojo"/>
</typeAliases>
</configuration>
（3）Spring配置文件：applicationContext.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.2.xsd">
<!-- 配置扫描注解 @Controller @Service -->
<context:component-scan base-package="com" />
<!-- SpringMVC使用<mvc:annotation-driven>自动加载RequestMappingHandlerMapping和RequestMappingHandlerAdapter -->
<mvc:annotation-driven />
<!-- 配置静态资源映射 -->
<mvc:resources location="/js/" mapping="/js/**"/>
<mvc:resources location="/css/" mapping="/css/**"/>
<mvc:resources location="/images/" mapping="/images/**"/>
<mvc:resources location="/img_source/" mapping="/img_source/**"/>
<mvc:resources location="/ueditor/" mapping="/ueditor/**"/>
<mvc:resources location="/utilLib/" mapping="/utilLib/**"/>
<!-- 配置视图解析器-->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<!-- 配置逻辑视图的前缀 -->
<property name="prefix" value="/WEB-INF/jsp/" />
<!-- 配置逻辑视图的后缀 -->
<property name="suffix" value=".jsp" />
</bean>
</beans>
最后需要在web.xml文件中进行配置：
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
version="2.5">
<display-name>SSM</display-name>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
<!-- spring监听器 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- 指定spring核心配置文件 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<!-- 处理POST提交乱码问题 -->
<filter>
<filter-name>encoding</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>encoding</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!-- 配置前端控制器 -->
<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!-- 指定配置文件位置和名称 如果不设置,默认找/WEB-INF/<servlet-name>-servlet.xml -->
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springmvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
最终的目录结构：
二、修改项目代码
将原项目的java类、页面文件复制进项目后，需要进行一定的修改使其基于spring框架运行
将原有的各个NewsServlet类集合到一个新建的NewsController类中
package com.controller;
import com.entity.News;
import com.entity.User;
import com.service.NewsService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.io.UnsupportedEncodingException;
import java.sql.SQLException;
import java.util.Arrays;
import java.util.List;
public class NewsController {
@Autowired
private NewsService newsService;
//显示所有新闻
@RequestMapping("/ShowNews")
public void ShowNews(HttpServletRequest request, HttpServletResponse response) throws UnsupportedEncodingException {
request.setCharacterEncoding("utf-8");
response.setCharacterEncoding("utf-8");
try {
List<News> newsList = newsService.QueryNews();
for (News s:newsList
) {
System.out.println(s.getNewsId());
}
request.setAttribute("News", newsList);
request.getRequestDispatcher("ShowNews.jsp").forward(request, response);
} catch (Exception e) {
e.printStackTrace();
}
}
@RequestMapping("/AddNews")
public void addNew(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException {
request.setCharacterEncoding("utf-8");
response.setCharacterEncoding("utf-8");
response.setHeader("Context-Type","text/html;charset=utf-8");
News news =new News();
news.setNewsId(Integer.valueOf(request.getParameter("newsid")));
news.setNewsAuthor(request.getParameter("author"));
news.setNewsContent(request.getParameter("Content"));
news.setNewsTitle(request.getParameter("title"));
NewsService newsService=new NewsService();
try {
newsService.AddNews(news);
request.getRequestDispatcher("ShowNews").forward(request,response);
} catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (SQLException e) {
e.printStackTrace();
}
}
@RequestMapping("/UpdateNews")
public void editNew(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException {
response.setContentType("text/html; charset=UTF-8");
request.setCharacterEncoding("UTF-8");
response.setHeader("Context-Type", "text/html;charset=utf-8");
News news = new News();
news.setNewsId(Integer.valueOf(request.getParameter("newsid")));
news.setNewsAuthor(request.getParameter("author"));
news.setNewsContent(request.getParameter("Content"));
news.setNewsTitle(request.getParameter("title"));
NewsService newsService = new NewsService();
try {
newsService.UpdateNews(news);
request.getRequestDispatcher("ShowNews").forward(request, response);
} catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (SQLException e) {
e.printStackTrace();
}
}
@RequestMapping("/deleteNew")
public void deleteNew(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException {
int newsID=Integer.valueOf(request.getParameter("newsid"));
NewsService newsService=new NewsService();
try {
newsService.DeleteNews(newsID);
} catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (SQLException e) {
e.printStackTrace();
}
request.getRequestDispatcher("com.controller.ShowNewsServlet").forward(request,response);
}
@RequestMapping("/viewNew")
public void viewNew(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException {
int newsID=Integer.valueOf(request.getParameter("newsid"));
NewsService newsService=new NewsService();
try {
News news=newsService.QueryIndividualNews(newsID);
request.setAttribute("news",news);
request.getRequestDispatcher("NewsDetail.jsp").forward(request,response);
}catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (SQLException e) {
e.printStackTrace();
}
}
}
将LoginServlet类改为UserController类
package com.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.io.PrintWriter;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;
@Controller
public class UserController {
@RequestMapping("/Login")
public void login(HttpServletRequest request, HttpServletResponse response) throws IOException {
response.setContentType("text/html; charset=UTF-8");
request.setCharacterEncoding("UTF-8");
response.setHeader("Context-Type", "text/html;charset=utf-8");
PrintWriter output = response.getWriter();
String uname = request.getParameter("username");
String pwd = request.getParameter("pwd");
ResultSet rs;
Statement statement = null;
Connection conn = null;
try {
Class.forName("com.mysql.cj.jdbc.Driver");
conn = DriverManager.getConnection("jdbc:mysql://localhost:3306?serverTimezone=GMT&characterEncoding=utf-8", "root", "Guozhaojie610");
String sql = "select * from new_schema.login where username='" + uname + "' and password='" + pwd + "'";
statement = conn.createStatement();
rs = statement.executeQuery(sql);
if (rs.next()) {
request.setAttribute("username", uname);
response.sendRedirect("index.html");
} else {
output.println("账号或密码错误");
response.sendRedirect("index.jsp");
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
实体类：
News
package com.entity;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
@Data
@AllArgsConstructor
@NoArgsConstructor
public class News {
private int newsId;
private String newsContent;
private String newsAuthor;
private String newsTitle;
public int getNewsId() {
return newsId;
}
public void setNewsId(int newsId) {
this.newsId = newsId;
}
public String getNewsContent() {
return newsContent;
}
public void setNewsContent(String newsContent) {
this.newsContent = newsContent;
}
public String getNewsAuthor() {
return newsAuthor;
}
public void setNewsAuthor(String newsAuthor) {
this.newsAuthor = newsAuthor;
}
public String getNewsTitle() {
return newsTitle;
}
public void setNewsTitle(String newsTitle) {
this.newsTitle = newsTitle;
}
}
User
package com.entity;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
@Data
@AllArgsConstructor
@NoArgsConstructor
public class User {
String username;
String password;
public String getUsername() {
return username;
}
public void setUsername(String username) { this.username = username; }
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
最后将页面的连接进行重定向，这里不再放出代码
最终项目结构：
三、最终效果展示
与MVC版本效果相同
