idea实现学生信息管理系统

根据提供的引用内容，可以使用以下步骤在IntelliJ IDEA中实现学生信息管理系统：

1. 创建一个新的Maven项目，并添加SpringMVC、Spring和MyBatis依赖项。

2. 创建一个数据库并设计学生信息表，包括学生ID、姓名、性别、年龄、班级等字段。

3. 创建一个Java类来表示学生信息，并使用MyBatis框架将其映射到数据库表中。

4. 创建一个SpringMVC控制器类来处理HTTP请求，并使用Spring框架将其注入到应用程序上下文中。

5. 创建一个JSP页面来显示学生信息，并使用JSTL标签库来访问控制器中的数据。

6. 使用过滤器拦截器来验证用户是否登录，并使用MVC模式分层来组织应用程序。

以下是一个简单的示例代码，用于在IntelliJ IDEA中实现学生信息管理系统：

// Student.java
public class Student {
    private int id;
    private String name;
    private String gender;
    private int age;
    private String className;

    // getters and setters
}

// StudentMapper.xml
<mapper namespace="com.example.mapper.StudentMapper">
    <resultMap id="studentMap" type="com.example.model.Student">
        <id property="id" column="id"/>
        <result property="name" column="name"/>
        <result property="gender" column="gender"/>
        <result property="age" column="age"/>
        <result property="className" column="class_name"/>
    </resultMap>

    <select id="getStudentById" resultMap="studentMap">
        SELECT * FROM student WHERE id = #{id}
    </select>

    <select id="getAllStudents" resultMap="studentMap">
        SELECT * FROM student
    </select>

    <insert id="addStudent" parameterType="com.example.model.Student">
        INSERT INTO student (name, gender, age, class_name) VALUES (#{name}, #{gender}, #{age}, #{className})
    </insert>

    <update id="updateStudent" parameterType="com.example.model.Student">
        UPDATE student SET name = #{name}, gender = #{gender}, age = #{age}, class_name = #{className} WHERE id = #{id}
    </update>

    <delete id="deleteStudent" parameterType="int">
        DELETE FROM student WHERE id = #{id}
    </delete>
</mapper>

// StudentController.java
@Controller
@RequestMapping("/student")
public class StudentController {
    @Autowired
    private StudentService studentService;

    @RequestMapping("/list")
    public ModelAndView list() {
        List<Student> students = studentService.getAllStudents();
        ModelAndView modelAndView = new ModelAndView("student/list");
        modelAndView.addObject("students", students);
        return modelAndView;
    }

    @RequestMapping("/add")
    public String add() {
        return "student/add";
    }

    @RequestMapping(value = "/doAdd", method = RequestMethod.POST)
    public String doAdd(Student student) {
        studentService.addStudent(student);
        return "redirect:/student/list";
    }

    @RequestMapping("/edit/{id}")
    public ModelAndView edit(@PathVariable int id) {
        Student student = studentService.getStudentById(id);
        ModelAndView modelAndView = new ModelAndView("student/edit");
        modelAndView.addObject("student", student);
        return modelAndView;
    }

    @RequestMapping(value = "/doEdit", method = RequestMethod.POST)
    public String doEdit(Student student) {
        studentService.updateStudent(student);
        return "redirect:/student/list";
    }

    @RequestMapping("/delete/{id}")
    public String delete(@PathVariable int id) {
        studentService.deleteStudent(id);
        return "redirect:/student/list";
    }
}

// StudentService.java
@Service
public class StudentService {
    @Autowired
    private StudentMapper studentMapper;

    public List<Student> getAllStudents() {
        return studentMapper.getAllStudents();
    }

    public Student getStudentById(int id) {
        return studentMapper.getStudentById(id);
    }

    public void addStudent(Student student) {
        studentMapper.addStudent(student);
    }

    public void updateStudent(Student student) {
        studentMapper.updateStudent(student);
    }

    public void deleteStudent(int id) {
        studentMapper.deleteStudent(id);
    }
}
