我在intellij上创建了一个简单的结构，使用spring boot，java和html和mysql来创建数据库。我想要做的是从html填充格式并将数据保存在我的数据库中。 当我使用存储库运行 @springboot 测试时，数据将保存在我的数据库中。但是当我尝试从 html 保存数据时什么也没有发生。我从谷歌浏览器打开 html 文件。
下面我给出了控制器、实体、存储库、资源和 sql 模式。
@RestController
public class PersonController {
@Autowired
private PersonRepository personRepository;
@GetMapping("/")
public String index(Model model) {
model.addAttribute("person", new Person());
model.addAttribute("people", personRepository.findAll());
return "index";
}
@PostMapping("/addPerson")
public String addPerson(@ModelAttribute Person person) {
personRepository.save(person);
return "redirect:/";
}
}
@Entity
public class Person {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
private String name;
private String email;
private LocalDate dob; // Date of Birth
// Getters and Setters
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public LocalDate getDob() {
return dob;
}
public void setDob(LocalDate dob) {
this.dob = dob;
}
}
public interface PersonRepository extends JpaRepository<Person, Long> { }
