我正在尝试使用 Thymeleaf 在 html 页面上显示本地数据库 (PostgreSQL) 中的所有客户。我的项目正在使用 Spring Boot。

连接和从数据库获取数据不是这个问题的重点(或者是?)。关键是 thymeleaf 看不到我通过 Controller 传递的模型。

<ul th:each="customer : ${customers}">

<span th:text="${customers.getPhone}">Phone</span>
<span th:text="${customers.getEmail}">e-mail</span>
</li>
</ul>
</body>
</html>

HomePageController.java

@Controller
@RequestMapping("/")
public class HomePageController {

private CustomerRepository customerRepository;

@Autowired
public HomePageController(CustomerRepository customerRepository){
this.customerRepository = customerRepository;
}


@RequestMapping(method = RequestMethod.GET)
public String homePage(Model model) {
List<Customer> customers = Lists.newArrayList(customerRepository.findAll());
model.addAttribute("customers", customers);
return "homePage";
}
}

CustomerRepository.java

@Repository
public interface CustomerRepository extends CrudRepository<Customer, Long> {
}

客户.java

@Entity
@Getter @Setter
public class Customer {

@Id
@GeneratedValue(strategy= GenerationType.AUTO)
private Long id;
@NotNull private String firstName;
@NotNull private String lastName;
@NotNull private String phoneNumber;
@NotNull private String email;

protected Customer(){}

public Customer(Long id, String firstName, String lastName, String phoneNumber, String email){
this.id = id;
this.firstName = firstName;
this.lastName = lastName;
this.phoneNumber = phoneNumber;
this.email = email;
}

@Override
public String toString(){
return String.format(
"Customer[id=%d, firstName='%s', lastName='%s', phoneNumber='%s', emailr='%s']",this.getId(),
firstName, lastName, phoneNumber, email);
}
}

编辑:一些英文更正:(

最佳答案

不要在模板中使用 getter。这样做:

<span th:text="${customer.firstName}">Name</span>

抱歉,您还必须删除 s
