我在使用 Spring Tool Suite 4 时遇到了这个问题，我已经用它完成了一个完全相同的项目，但在这个项目中，它变得很糟糕。我已经检查了代码数百次，并且没有更多的提示来修复它......在发布问题之前我已经搜索了堆栈溢出。我找到了一些解决方案，但以不同的方式使用@Service，这不是我的情况，因为这只是我的应用程序的后端。谢谢
这是我的模型类:
package br.unifor.bocume.api.models;
import java.util.List;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.OneToMany;
import javax.validation.constraints.NotEmpty;
import javax.validation.constraints.Size;
@Entity
public class Customer {
@Id
@GeneratedValue (strategy = GenerationType.IDENTITY)
@Column (name = "customer_id")
private Long customer_id;
@NotEmpty
@Size (max = 80)
@Column (name = "customer_name")
private String customer_name;
@NotEmpty
@Size (max = 80)
@Column (name = "customer_email")
private String customer_email;
@NotEmpty
@Size (max = 200)
@Column (name = "customer_address")
private String customer_address;
@NotEmpty
@Size (max = 20)
@Column (name = "customer_cpf")
private String customer_cpf;
@OneToMany(mappedBy = "customer")
@Column(name="cc_id", nullable = true)
private List<CreditCard> ccList;
@Override
public int hashCode() {
final int prime = 31;
int result = 1;
result = prime * result + ((customer_id == null) ? 0 : customer_id.hashCode());
return result;
}
@Override
public boolean equals(Object obj) {
if (this == obj)
return true;
if (obj == null)
return false;
if (getClass() != obj.getClass())
return false;
Customer other = (Customer) obj;
if (customer_id == null) {
if (other.customer_id != null)
return false;
} else if (!customer_id.equals(other.customer_id))
return false;
return true;
}
public Long getCustomer_id() {
return customer_id;
}
public void setCustomer_id(Long customer_id) {
this.customer_id = customer_id;
}
public String getCustomer_name() {
return customer_name;
}
public void setCustomer_name(String customer_name) {
this.customer_name = customer_name;
}
public String getCustomer_email() {
return customer_email;
}
public void setCustomer_email(String customer_email) {
this.customer_email = customer_email;
}
public String getCustomer_address() {
return customer_address;
}
public void setCustomer_address(String customer_address) {
this.customer_address = customer_address;
}
public String getCustomer_cpf() {
return customer_cpf;
}
public void setCustomer_cpf(String customer_cpf) {
this.customer_cpf = customer_cpf;
}
public List<CreditCard> getCcList() {
return ccList;
}
public void setCcList(List<CreditCard> ccList) {
this.ccList = ccList;
}
}
然后，我的 Controller :
package br.unifor.bocume.api.controller;
import java.util.List;
import java.util.Optional;
import javax.validation.Valid;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.CrossOrigin;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseStatus;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.server.ResponseStatusException;
import br.unifor.bocume.api.models.Customer;
import br.unifor.bocume.api.repository.CustomerRepository;
@CrossOrigin
@RestController
@RequestMapping ("/customers")
public class CustomerController {
@Autowired
private CustomerRepository customers;
@GetMapping
public List<Customer> customersList() {
return customers.findAll();
}
@GetMapping ("/{id}")
public ResponseEntity<Customer> fetchCustomer(@PathVariable Long id) {
Optional<Customer> customer = customers.findById(id);
if (customer.isEmpty()) {
return ResponseEntity.notFound().build();
}
return ResponseEntity.ok(customer.get());
}
@PostMapping
@ResponseStatus(HttpStatus.CREATED)
public Customer addCustomer(@Valid @RequestBody Customer customer) {
Optional<Customer> myCustomer = customers.findByNameAndCpf(customer.getCustomer_name(), customer.getCustomer_cpf());
if (myCustomer.isPresent()) {
throw new ResponseStatusException(HttpStatus.BAD_REQUEST,
"Customer already exists");
}
return customers.save(customer);
}
}
最后，我的存储库:
package br.unifor.bocume.api.repository;
import java.util.Optional;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;
import br.unifor.bocume.api.models.Customer;
@Repository
public interface CustomerRepository extends JpaRepository<Customer, Long> {
Optional<Customer> findByNameAndCpf(String name, String cpf);
}
异常(exception)情况是:

最佳答案
从 Customer 实体类的属性名称中删除所有 customer_ 前缀。正如日志中提到的，spring 正在尝试从存储库方法 findByNameAndCpf 创建查询，同时尝试查找属性 name 和 cpf 在您的 Customer 类中，它无法找到这些名称的任何属性。或者，您可以根据属性更改方法名称，例如 findByCustomer_NameAndCustomer_Cpf
