<think>根据用户要求，我们需要将校园信息管理系统需求分析文档（学生填写版）的
实现分为三类。结合用户提供的引用内容和之前的讨论，这三类可以理解为：
1. **系统架构与技术
实现类**：包含系统整体设计、技术选型、核心架构等
2
. **功能模块与业务逻辑类**：包含具体功能
实现、CRUD操作、业务规则等
3
. **安全与扩展性类**：包含权限管理、系统安全、性能优化等
下面按照这三个类别，用Java
实现相关要求：
### 一、系统架构与技术
实现类
####
1.1 技术选型
采用Spring Boot + MyBatis框架
实现B/S架构系统[^2]，数据库使用My
SQL 8
.0，前端使用Thymeleaf + Bootstrap 5。
####
1.2 核心架构设计
```java
// 主应用类
@SpringBootApplication
public class CampusInfoSystemApp {
public static void main
(String[] args
) {
SpringApplication
.run
(CampusInfoSystemApp
.class, args
);
}
}
// 分层架构
- controller
(表现层
)
- service
(业务逻辑层
)
- dao
(数据访问层
)
- entity
(实体层
)
```
####
1.3 数据库配置
```java
# application
.properties
spring
.datasource
.url=
jdbc:my
sql://localhost:3306/campus_db?useSSL=false
spring
.datasource
.username=root
spring
.datasource
.password=
123456
spring
.datasource
.driver-class-name=com
.my
sql.cj
.jdbc.Driver
mybatis
.mapper-locations=classpath:mapper/*
.xml
```
### 二、功能模块与业务逻辑类
#### 2
.1 学生信息管理模块
```java
// 实体类（体现继承关系）
@MappedSuperclass
public abstract class Person {
@Id
@GeneratedValue
(strategy = GenerationType
.IDENTITY
)
private Long id;
private String number; // 学号/工号
private String name;
private int age;
// getters/setters
}
@Entity
@Table
(name = "students"
)
public class Student extends Person {
private String className;
private double score;
// 业务规则校验
public void setScore
(double score
) {
if
(score < 0 || score >
100
) {
throw new IllegalArgumentException
("成绩必须在0-
100之间"
);
}
this
.score = score;
}
}
// CRUD服务
实现
@Service
public class StudentServiceImpl implements StudentService {
@Autowired
private StudentRepository repository;
@Override
public Student addStudent
(Student student
) {
// 学号唯一性校验
if
(repository
.existsByNumber
(student
.getNumber
())) {
throw new DuplicateKeyException
("学号已存在"
);
}
return repository
.save
(student
);
}
}
```
#### 2
.2 教师信息管理模块
```java
@Entity
@Table
(name = "teachers"
)
public class Teacher extends Person {
private String subject;
private BigDecimal salary;
public void setSalary
(BigDecimal salary
) {
if
(salary
.compareTo
(BigDecimal
.ZERO
) < 0
) {
throw new IllegalArgumentException
("薪资不能为负数"
);
}
this
.salary = salary;
}
}
```
### 三、安全与扩展性类
#### 3
.1 RBAC权限管理
```java
// 权限枚举
public enum Permission {
STUDENT_VIEW,
STUDENT_EDIT,
TEACHER_VIEW,
TEACHER_EDIT,
ADMIN_DASHBOARD
}
// Spring Security配置
@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure
(HttpSecurity http
) throws Exception {
http
.authorizeRequests
()
.antMatchers
("/students/**"
).hasAnyAuthority
("STUDENT_EDIT"
)
.antMatchers
("/teachers/**"
).hasAnyAuthority
("TEACHER_EDIT"
)
.anyRequest
().authenticated
();
}
}
```
#### 3
.2 性能优化
```java
// 使用二级缓存提升查询性能
@Cacheable
(value = "students", key = "#id"
)
public Student getStudentById
(Long id
) {
return repository
.findById
(id
).orElse
(null
);
}
// 批量插入优化
@Transactional
public void batchInsertStudents
(List<Student> students
) {
jdbcTemplate
.batchUpdate
("INSERT INTO students
(...) VALUES
(...)"
);
}
```
### 文档结构
实现
```java
// 自动生成需求文档工具类
public class DocumentGenerator {
public void generateDoc
(String templatePath, Map<String, Object> data
) {
// 使用Freemarker模板引擎生成Word文档
Configuration cfg = new Configuration
(Configuration
.VERSION_2_3_30
);
cfg
.setClassForTemplateLoading
(this
.getClass
(), "/templates"
);
Template template = cfg
.getTemplate
("requirement_template
.ftl"
);
try
(Writer writer = new FileWriter
("校园信息管理系统需求文档
.docx"
)) {
template
.process
(data, writer
);
}
}
}
```
### 测试设计
```java
// 使用JUnit5测试实体类校验规则
class StudentValidationTest {
@Test
void whenScoreLessThan0_thenThrowException
() {
Student student = new Student
();
assertThrows
(IllegalArgumentException
.class,
() -> student
.setScore
(-5
));
}
@ParameterizedTest
@CsvSource
({"2023000
1, true", "20230002, false"}
)
void testCheckStudentNumberUnique
(String number, boolean expected
) {
when
(repository
.existsByNumber
(number
)).thenReturn
(expected
);
boolean result = service
.checkNumberUnique
(number
);
assertEquals
(expected, result
);
}
}
```

</think>### 校园信息管理系统需求分析文档（Java
实现）分类方案
根据引用文档和系统特性，我将
实现方案分为以下三类：
---
### 一、核心功能
实现类（CRUD与业务逻辑）
####
1. 实体类设计（继承体系）
```java
// 基类Person（抽象封装）
public abstract class Person {
private String id; // 学号/工号
private String name;
private int age;
// 封装校验规则
public void setAge
(int age
) {
if
(age <= 0
) throw new IllegalArgumentException
("年龄必须为正整数"
);
this
.age = age;
}
// 公共getter/setter
...
}
// 学生子类
public class Student extends Person {
private String className; // 班级
private double score; // 成绩
public void setScore
(double score
) {
if
(score < 0 || score >
100
)
throw new IllegalArgumentException
("成绩范围0-
100"
);
this
.score = score;
}
}
// 教师子类
public class Teacher extends Person {
private String subject; // 科目
private BigDecimal salary; // 薪资
public void setSalary
(BigDecimal salary
) {
if
(salary
.compareTo
(BigDecimal
.ZERO
) <= 0
)
throw new IllegalArgumentException
("薪资必须为正数"
);
this
.salary = salary;
}
}
```
#### 2
. CRUD服务层
实现
```java
// 学生服务接口
public interface StudentService {
Student addStudent
(Student student
) throws DuplicateKeyException;
Student getStudentById
(String id
);
Student updateStudent
(Student student
) throws NotFoundException;
void deleteStudent
(String id
);
List<Student> searchStudents
(String keyword
);
}
// 服务
实现（Spring Boot示例）
@Service
public class StudentServiceImpl implements StudentService {
@Autowired
private StudentRepository repository;
@Override
@Transactional
public Student addStudent
(Student student
) {
if
(repository
.existsById
(student
.getId
())) {
throw new DuplicateKeyException
("学号已存在"
);
}
return repository
.save
(student
);
}
}
```
---
### 二、系统架构类（技术
实现框架）
####
1. Spring Boot主配置
```java
@SpringBootApplication
public class CampusInfoSystemApp {
public static void main
(String[] args
) {
SpringApplication
.run
(CampusInfoSystemApp
.class, args
);
}
}
```
#### 2
. 数据库集成（MyBatis + My
SQL）
```xml
<!-- pom
.xml 依赖 -->
<dependency>
<groupId>org
.mybatis
.spring
.boot</groupId>
<artifactId>mybatis-spring-boot-starter</artifactId>
<
version>3
.0
.3</
version>
</dependency>
<dependency>
<groupId>com
.my
sql</groupId>
<artifactId>my
sql-connector-j</artifactId>
</dependency>
```
#### 3
. RESTful接口设计
```java
@RestController
@RequestMapping
("/api/students"
)
public class StudentController {
@PostMapping
public ResponseEntity<?> createStudent
(@Valid @RequestBody Student student
) {
return ResponseEntity
.created
(URI
.create
("/students/" + student
.getId
()))
.body
(studentService
.addStudent
(student
));
}
}
```
---
### 三、安全与扩展类（RBAC+校验）
####
1. RBAC权限控制
```java
// Spring Security配置
@Configuration
@EnableWebSecurity
public class SecurityConfig {
@Bean
public SecurityFilterChain filterChain
(HttpSecurity http
) throws Exception {
http
.authorizeHttpRequests
(auth -> auth
.requestMatchers
("/admin/**"
).hasRole
("ADMIN"
)
.requestMatchers
("/teacher/**"
).hasAnyRole
("TEACHER", "ADMIN"
)
.requestMatchers
("/student/**"
).hasAnyRole
("STUDENT", "ADMIN"
)
);
return http
.build
();
}
}
```
#### 2
. 数据校验增强
```java
// 自定义学号校验器
public class StudentIdValidator implements ConstraintValidator<ValidStudentId, String> {
@Override
public boolean isValid
(String id, ConstraintValidatorContext context
) {
return id != null && id
.matches
("2024\\d{4}"
); // 2024+4位数字
}
}
```
#### 3
. 扩展接口设计
```java
// 可扩展的模块接口
public interface InfoManageable<T> {
T create
(T entity
);
T update
(T entity
);
void delete
(String id
);
T getById
(String id
);
}
//
实现示例
@Service
public class TeacherService implements InfoManageable<Teacher> {
//
实现CRUD方法
...
}
```
---
### 文档生成辅助工具
```java
// 自动生成需求文档（Freemarker示例）
public class DocumentGenerator {
public void generateDoc
(Map<String, Object> data
) {
Configuration cfg = new Configuration
(Configuration
.VERSION_2_3_3
1);
cfg
.setClassForTemplateLoading
(this
.getClass
(), "/templates"
);
Template template = cfg
.getTemplate
("requirement_template
.ftl"
);
try
(Writer writer = new FileWriter
("需求文档
.docx"
)) {
template
.process
(data, writer
);
}
}
}
```
