## 專案環境
- JDK: 1.8
- IDE: IDEA 201903
- DataBase: MySQL 8.0
- Mybatis: 3.5.2
- POM: Maven
- Tomcat 9
- Bootstrap 3
- JQuery 2
- lombok 外掛
- 分頁外掛: PageHelper 5.1.11
- 涉及技術 MySQL資料庫，Spring，JavaWeb及MyBatis，簡單的前端知識
## 專案詳情
### 設計資料庫
> 大二沒有好好學系統設計與分析，畫的圖一塌糊塗。
> 包含兩個實體類，使用者&管理員
>
> 生成該資料庫的sql檔案 在該[GitHub](https://github.com/CPG123456/GymMS)跳轉GitHub /sql 目錄下
> 生成表如圖示
### 設計要實現的功能
> 應該叫做用例圖吧，但我的好多符號都是錯的，再次後悔沒有好好學習！
### 製作前端頁面Demo
> 設計該圖的[網址](www.processon.com)
其實這一步放在後面也合適，我為了讓自己吃大餅，就先設計了一下。
### 環境配置
> 專案檔案結構如圖所示
#### 基本步驟
1. 新建Maven專案，新增web支援
2. 匯入pom依賴
```xml
junit 4.12
mysql
mysql-connector-java
5.1.47
com.mchange
c3p0
0.9.5.2
javax.servlet
servlet-api
2.5
javax.servlet.jsp 2.2
javax.servlet
jstl
1.2
org.mybatis
mybatis
3.5.2
org.mybatis
mybatis-spring
2.0.2
org.springframework 5.1.9.RELEASE
org.springframework
spring-jdbc
5.1.9.RELEASE
```
3. Maven資源過濾
```xml
src/main/java
**/*.properties
**/*.xml
false
src/main/resources
**/*.properties
**/*.xml
false
```
4. 建立基本結構框架 （如上所示[點此跳轉](# 環境配置)
5. 建立基本配置
- mybatis-config.xml
```xml
```
- applicationContext.xml
```xml
```
6. Mybatis層編寫
- 資料庫配置檔案 **database.properties**
```properties
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssmbuild?useSSL=true&useUnicode=true&characterEncoding=utf8
jdbc.username=root
jdbc.password=123456IDEA關聯資料庫
```
- IDEA關聯資料庫
- 編寫MyBatis的核心配置檔案
```xml
```
### POJO Mapper Services的編寫
#### POJO
1. User
```java
@Data //使用lombok外掛即可省寫get set
@AllArgsConstructor
@NoArgsConstructor
public class User {
private int id;
private String username;
private String password;
private String name;
private String sex;
private String telephone;
private int age;
private String begintime;
private String endtime;
private int remainday;
private int addday;
public static void main(String[] args) {
User u = new User();
u.getTelephone();
}
}
```
2. Admin
```java
@Data
@NoArgsConstructor
@AllArgsConstructor
public class Admin {
private int id;
private String username;
private String password;
private String name;
private String telephone;
}
```
#### Mapper
1. 編寫DAO層的Mapper介面
1. 1 userMapper
```java
public interface UserMapper {
//通過id查詢
User queryUserById(int id);
// 查詢到期時間
Date queryDateById(int id);
//修改賬號密碼
int updateNP(User user);
//login
User userLogin(User user);
//會員註冊
int userRegister(User user);
}
```
1. 2 adminMapper
```java
@Mapper
@Component
public interface AdminMapper{
//查詢會員
List queryUser();
//新增會員
int addUser(User user);
//刪除會員
int deleteUserById(int id);
//更新會員
int updateUser(User user);
//根據id查詢一個會員
User queryUserById(int id);
//根據姓名查詢一個會員
User queryUserByName(String name);
//login
Admin adminLogin(Admin admin);
//查詢使用者總數
int selectTotal();
// 分頁
@Select("select * from gymms.user")
@Results({
// 使用者資訊，只要指定id列與屬性的對映關係，其他列會自動封裝（屬性與列一致）
@Result(property = "id", column = "id"),
// 資訊
@Result(property = "id", column = "id"),
@Result(property = "username", column = "username"),
@Result(property = "password", column = "password"),
@Result(property = "name", column = "name"),
@Result(property = "sex", column = "sex"),
@Result(property = "telephone", column = "telephone"),
@Result(property = "age", column = "age"),
@Result(property = "begintime", column = "begintime"),
@Result(property = "endtime", column = "endtime"),
@Result(property = "remainday", column = "remainday")
})
List findAll();
}
```
2. 編寫介面對應的 Mapper.xml 檔案
2. 1 userMapper.xml
```xml
update gymms.user
set username = #{username},password = #{password}
where id = #{id}
insert into gymms.user(username,password,name,sex,telephone,age,begintime,endtime,remainday)
values (#{username},#{password},#{name},#{sex},#{telephone},#{age},#{begintime},#{endtime},#{remainday})
```
2. 2 adminMapper.xml
```xml
insert into gymms.user(username,password,name,sex,telephone,age,begintime,endtime,remainday)
values (#{username},#{password},#{name},#{sex},#{telephone},#{age},#{begintime},#{endtime},#{remainday})
delete from gymms.user where id=#{id}
update gymms.user
set username = #{username},password = #{password},name = #{name},sex = #{sex},telephone = #{telephone},
age = #{age},endtime = #{endtime},remainday = #{remainday}
where id = #{id}
```
3. 編寫Service層的介面和實現類
3. 1 userService
```java
public interface UserService {
// 查詢到期時間
Date queryDateById(int id);
//修改賬號密碼
int updateNP(User user);
//login
User userLogin(User user);
//通過id查詢
User queryUserById(int id);
//會員註冊
int userRegister(User user);
}
```
3. 2 adminService
```java
public interface AdminService {
//查詢會員
List queryUser();
//新增會員
int addUser(User user);
//刪除會員
int deleteUserById(int id);
//更新會員
int updateUser(User user);
//根據id查詢一個會員
User queryUserById(int id);
//根據姓名查詢一個會員
User queryUserByName(String name);
//login
Admin adminLogin(Admin admin);
//查詢使用者總數
int selectTotal();
// 分頁
List findAll();
/**
* 分頁查詢
* @param pageNum 當然頁
* @param pageSize 頁大小
* @return 返回PageHelper提供的封裝分頁引數的PageInfo物件
*/
PageInfo findByPage(int pageNum, int pageSize);
}
```
3. 3 userServiceImpl
```java
public class UserServiceImpl implements UserService {
private UserMapper userMapper;
public void setUserMapper(UserMapper userMapper) {
this.userMapper = userMapper;
}
public Date queryDateById(int id) {
return userMapper.queryDateById(id);
}
public int updateNP(User user) {
return userMapper.updateNP(user);
}
public User userLogin(User user) {
return userMapper.userLogin(user);
}
public User queryUserById(int id) {
return userMapper.queryUserById(id);
}
public int userRegister(User user) {
return userMapper.userRegister(user);
}
}
```
3. 4 adminServiceImpl
```java
public class AdminServiceImpl implements AdminService {
private AdminMapper adminMapper;
public void setAdminMapper(AdminMapper adminMapper) {
this.adminMapper = adminMapper;
}
public List queryUser() {
return adminMapper.queryUser();
}
public int addUser(User user) {
return adminMapper.addUser(user);
}
public int deleteUserById(int id) {
return adminMapper.deleteUserById(id);
}
public int updateUser(User user) {
return adminMapper.updateUser(user);
}
public User queryUserById(int id) {
return adminMapper.queryUserById(id);
}
public User queryUserByName(String name) {
return adminMapper.queryUserByName(name);
}
public Admin adminLogin(Admin admin) {
return adminMapper.adminLogin(admin);
}
public int selectTotal() {
return adminMapper.selectTotal();
}
public List findAll() {
return adminMapper.findAll();
}
public PageInfo findByPage(int pageNum, int pageSize) {
PageHelper.startPage(pageNum, pageSize);
List list = adminMapper.findAll();
PageInfo pageInfo = new PageInfo<>(list);
return pageInfo;
}
}
```
#### Spring層
- 配置**Spring整合MyBatis**，我們這裡資料來源使用c3p0連線池；
- 編寫Spring整合Mybatis的相關的配置檔案；
spring-dao.xml
```xml
```
- **Spring整合service層**
```xml
```
#### SpringMVC層
- **web.xml**
```xml
DispatcherServlet
org.springframework.web.servlet.DispatcherServlet
contextConfigLocation
classpath:applicationContext.xml
1
DispatcherServlet
/
encodingFilter
org.springframework.web.filter.CharacterEncodingFilter
encoding
utf-8
encodingFilter
/*
15
```
- **spring-mvc.xml**
```xml
```
- **Spring配置整合檔案，applicationContext.xml**
```xml
```

### 拓展與展望
以下功能在以後可拓展開發
## 結束與總結
這個小Demo做了五六天,分頁那裡卡了接近兩天，無數的坑等著踩。
期間也體會到了程式設計的樂趣，每天晚上都肝的快快樂樂。
所有程式碼放在GitHub供大家交流學習。
今天母親節呀，祝我媽媽母親節快樂！
