首先打开idea新建一个springboot项目：file-new project
在这里插入图片描述

然后点击next

分别选中web ->web TemplateEngine-> freemarker SQL->jpa
然后next ->finish
pom文件如下`<?xml version="1.0" encoding="UTF-8"?>

` springboot目录结构如下 ![在这里插入图片描述](https://img-blog.csdn.net/20181002093827398?watermark/2/text/aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2NzZG5fbXlwcm9ncmFtTGlmZQ==/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70) application.properties配置文件如下： 
#基本配置
server.port=8080
server.servlet.context-path=/springBoot
#spring.mvc.view.prefix=classpath:/templates/
#spring.mvc.view.suffix=.jsp
#spring.freemarker.prefix=classpath:/templates/
spring.freemarker.suffix=.html
spring.freemarker.request-context-attribute=rc
spring.freemarker.expose-request-attributes=true
spring.freemarker.settings.auto_import=common/include.html as common

#MySQL
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/mytest?characterEncoding=utf8
spring.datasource.username=root
spring.datasource.password=root
#jpa
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=update
jpa.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect

jpa如下：src->main->java->包名

@Repository
public interface StudengRepository extends JpaRepository<Student,Integer> {
    Student findStudentByAge(Integer age);
}

service :

public interface StudentService {
    List<Student>getList();
    void add(Student student);
    Student findByAge(Integer age);
    void delete(Student student);

    List<Student> findAll();
}

service实现类：

@Service
public class StudentServiceImpl implements StudentService {
    @Autowired
    private StudengRepository studengRepository;
    @Override
    public List<Student> getList() {
        return studengRepository.findAll();
    }

    @Override
    public void add(Student student) {
        Student student1=new Student();
        student1.setAge(26);
        student1.setName("li");
        student1.setScore(100);
        student1.setSex("女");
        studengRepository.save(student1);
    }

    @Override
    public Student findByAge(Integer age) {
        return studengRepository.findStudentByAge(age);
    }

    @Override
    public void delete(Student student) {
        studengRepository.delete(student);
    }

    @Override
    public List<Student> findAll() {
        return studengRepository.findAll();
    }
}

controller如下：

@Controller
public class StudentController {
    @Autowired
   private StudentService studentService;

/*    @GetMapping(value = "/getList")
    @ResponseBody
    public List<Student> getList(){
    List<Student> students=studentService.getList();
       return students;
    }*/
    @RequestMapping(value = "/list")
    public ModelAndView show(Model model, ModelAndView modelAndView) {
        modelAndView.setViewName("student_list");
        List<Student> students = studentService.findAll();
        model.addAttribute("student", students);
        return modelAndView;

    }
 

    @GetMapping(value = "/delete/{id}")
    @ResponseBody
    public void delete(Student student){
        studentService.delete(student);
    }

freemarker如下：list页面如下
