基于 SSM 框架的 Soso 移动业务大厅

一、整体基本实现情况

对本学期的 Java 作业 1 的 SOSO 移动大厅进行改进，基于 SSM、JSP、Maven、Tomcat、MySQL 等实现。

二、实现详情

1、工程结构图

2、工程结构各部分实现

（1）Java

pojo: 存放自定义的 Java 类。每个类的属性设为 private，并提供 public 属性的 getter/setter 方法让外界访问。

// MobileCard.java

``` package com.pojo;

//手机卡类 public class MobileCard { private String cardNumber; //卡号 private String userName; //用户名 private String passWord; //密码 private String serPackage; //服务包 private double consumAmount; //总消费额 private double money; //余额 private int realTalkTime; //实际通话时间 private int realSMSCount; //实际短信数量 private int realFlow; //实际流量消耗

public MobileCard() {
    this.realTalkTime = 0;
    this.realSMSCount = 0;
    this.realFlow = 0;
}

public String getcardNumber() {
    return cardNumber;
}
public String getuserName() {
    return userName;
}
public String getpassWord() {
    return passWord;
}
public String getserPackage() {
    return serPackage;
}
public double getconsumAmount() {
    return consumAmount;
}
public double getmoney() {
    return money;
}
public int getrealTalkTime() {
    return realTalkTime;
}
public int getrealSMSCount() {
    return realSMSCount;
}
public int getrealFlow() {
    return realFlow;
}

public void setcardNumber(String temp) {
    cardNumber = temp;
}
public void setuserName(String temp) {
    userName = temp;
}
public void setpassWord(String temp) {
    passWord = temp;
}
public void setserPackage(String temp) { serPackage = temp; }
public void setconsumAmount(double temp) {
    consumAmount = temp;
}
public void setmoney(double temp) {
    money = temp;
}
public void setrealTalkTime(int temp) {
    realTalkTime = temp;
}
public void setrealSMSCount(int temp) {
    realSMSCount = temp;
}
public void setrealFlow(int temp) {
    realFlow = temp;
}

} ```

service：定义接口，包含系统所提供的功能。此外还会在 service 包下再新建 impl 包。

//SosoService.java

``` package com.service; import com.pojo.MobileCard; import java.util.List;

public interface SosoService { int userRegister(MobileCard newUser);

List<MobileCard> queryAllUser();

}

```

dao：定义接口，包含与数据库进行交互的功能。

//SosoDao.java

``` package com.dao; import com.pojo.MobileCard; import java.util.List;

public interface SosoDao { int userRegister(MobileCard newUser); List queryAllUser(); } ```

controller：控制器，负责接收页面请求，转发和处理。

//SosoController.java

``` package com.controller; import com.pojo.MobileCard; import com.service.SosoService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.RequestMapping;

import javax.servlet.http.HttpServletRequest; import java.util.List;

@Controller @RequestMapping("/soso") public class SosoController { @Autowired private SosoService sosoService; @Autowired HttpServletRequest request;

@RequestMapping("/userRegisterWeb")
public String userRegisterWeb(MobileCard newUser) {
    return "userRegister";
}

@RequestMapping(value = "/userRegister")
public String userRegister() {
    MobileCard newUser = new MobileCard();
    newUser.setcardNumber(request.getParameter("cardNumber"));
    newUser.setuserName(request.getParameter("userName"));
    newUser.setpassWord(request.getParameter("passWord"));
    newUser.setserPackage(request.getParameter("serPackage"));
    newUser.setconsumAmount(Double.valueOf(request.getParameter("consumAmount")));
    newUser.setmoney(Double.valueOf(request.getParameter("money")));
    newUser.setrealTalkTime(Integer.valueOf(request.getParameter("realTalkTime")));
    newUser.setrealSMSCount(Integer.valueOf(request.getParameter("realSMSCount")));
    newUser.setrealFlow(Integer.valueOf(request.getParameter("realFlow")));
    sosoService.userRegister(newUser);
    return "userRegister";
}

@RequestMapping("/allUserWeb")
public String allUserWeb(Model model) {
    List<MobileCard> list = sosoService.queryAllUser();
    model.addAttribute("list", list);
    return "allUser";
}

} ```

（2）resource

在 resource 包下有两个文件夹， “mapper”（用于存放 xxxMapper.xml 文件）和“Spring”（用于存放 spring-xxx.xml 配置文件）。

jdbc.properties：MySQL 数据库配置文件

log4j.properties：日志输出配置文件

mybatis-config.xml：MyBatis 框架配置文件

//mapper 文件

```

<insert id="userRegister" parameterType="MobileCard">
    INSERT INTO MobileCardMYSQL(CardNumber,UserName,PassWord,SerPackage,ConsumAmount,Money, RealTalkTime, RealSMSCount, RealFlow) VALUE (#{cardNumber},#{userName}, #{passWord}, #{serPackage}, #{consumAmount},#{money}, #{realTalkTime}, #{realSMSCount}, #{realFlow})
</insert>

<select id="queryAllUser" resultMap="sosoResultMap">
    SELECT * FROM MobileCardMYSQL
</select>

```

// jdbc.properties

jdbc.driver=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://127.0.0.1:3306/soso?useUnicode=true&characterEncoding=utf8 jdbc.username=root jdbc.password=root

// log4j.properties

log4j.rootLogger=ERROR, stdout log4j.appender.stdout=org.apache.log4j.ConsoleAppender log4j.appender.stdout.layout=org.apache.log4j.PatternLayout log4j.appender.stdout.layout.ConversionPattern=%5p [%t] - %m%n

// mybatis-config.xml

```

    <!-- 使用列别名替换列名 默认:true -->
    <setting name="useColumnLabel" value="true" />

    <!-- 开启驼峰命名转换:Table{create_time} -> Entity{createTime} -->
    <setting name="mapUnderscoreToCamelCase" value="true" />
</settings>

```

（3）JSP

Web 界面配置

// index.jsp 主界面

``` <%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8" %> <% pageContext.setAttribute("path", request.getContextPath()); %>

首页

用户登录

用户注册

使用嗖嗖

话费充值

资费说明

退出系统

```

（4）pom.xml

在此文件中配置项目所需要的 jar 包。

```
