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

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>
    
    <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">

    
    <context:component-scan base-package="com" />

    
    <mvc:annotation-driven />

    

    <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/**"/>

    
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        
        <property name="prefix" value="/WEB-INF/jsp/" />
        
        <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>SSMdisplay-name>

  <welcome-file-list>
    <welcome-file>index.jspwelcome-file>
  welcome-file-list>

  
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListenerlistener-class>
  listener>

  
  <context-param>
    <param-name>contextConfigLocationparam-name>
    <param-value>classpath:applicationContext.xmlparam-value>
  context-param>

  
  <filter>
    <filter-name>encodingfilter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilterfilter-class>

  <filter-mapping>
    <filter-name>encodingfilter-name>
    <url-pattern>/*url-pattern>

  servlet>
  <servlet-mapping>
    <servlet-name>springmvcservlet-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 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
