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。

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);
}
}

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
关于java - Thymeleaf 没有看到来自 Controller 的引用，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/41595079/
