配置recource

1.配置JDBC

druid.driver=com.mysql.jdbc.Driver
druid.url=jdbc:mysql://localhost:3306/all_db?characterEncoding=utf-8
druid.username=root
druid.password=zxl19981019

2。配置Mybatis的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.配置spring的配置文件

<?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>

 

配置web.xml文件

<?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>

 

 

修改mvc项目中的java类文件

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();
        }
    }
    
}

 

原有的user类与news类导入:

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;
    }

}
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;
    }
}

 

效果图与mvc相同
