java - 如何在 Spring Boot Rest 和 Postman 中使用表单数据来保存用户？

Question

我正在开发一个用于登录和注册的 Spring Boot Rest API。我能够通过使用 postman 正文中的 @RequestBody 作为原始数据将数据保存在数据库中。但我想从 postman 发送每个字段的表单数据。在这种情况下，我应该在 Controller 中使用哪个注释。

如果有人有一个简单的例子，那就太好了!

Dao 类 -

@Repository
public class CustomerDaoImpl implements CustomerDao {

@Autowired
private SessionFactory sessionFactory;

@Override
public List<Customer> getCustomers() {

    Session session = sessionFactory.getCurrentSession(); 
    
    Query<Customer> query = session.createQuery("from Customer", 
                                                Customer.class);
    
    List<Customer> customers = query.getResultList();
    
    return customers;
}

@Override
public Customer getCustomer(int id) {
    
    Session session = sessionFactory.getCurrentSession(); 

    Customer customer = session.get(Customer.class, id);
    
    return customer;
}

@Override
public void saveCustomer(Customer theCustomer) {
    
    Session session = sessionFactory.getCurrentSession();
    
    session.saveOrUpdate(theCustomer);

}

@Override
public void deleteCustomer(int Id) {

    Session session = sessionFactory.getCurrentSession();
    
    Query query = session.createQuery("Delete from Customer where id=:customerId");
    
    query.setParameter("customerId", Id);
    
    query.executeUpdate();
}

@Override
public Customer getCustomer(String emailId, String password) {
    Customer customer = null;
    Session session = sessionFactory.getCurrentSession();
    Query<Customer> query = session.createQuery("from Customer where emailId=:emailId and "
            + " password=:password");
    
    query.setParameter("emailId", emailId);
    query.setParameter("password", password);
    
    List<Customer> list = query.getResultList();
    
    try {
        return customer = list.get(0);
    }
    catch(Exception e) {
        e.getMessage();
        return null;
    }
 }

}

POJO 类 -

    import java.sql.Timestamp;



    @Entity
    @Table(name="tbl_user_register")
    @JsonInclude(Include.NON_EMPTY) 
    @JsonIgnoreProperties(ignoreUnknown = true)

    public class Customer {

    @Id

    public Customer(String name, String emailId, String mobile, String businessName, String address, String password,
            Timestamp created, int userType, int parentType) {
        super();
        this.name = name;

        this.created = created;
        this.userType = userType;
        this.parentType = parentType;
    }



    public Customer(int id, String name, String emailId, String mobile, String businessName, String address,
            String password, Timestamp created, int userType, int parentType) {
        super();
        this.id = id;
        this.name = name;
        this.emailId = emailId;
        this.mobile = mobile;
        this.businessName = businessName;
        this.address = address;
        this.password = password;
        this.created = created;
        this.userType = userType;
        this.parentType = parentType;
    }

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getEmailId() {
        return emailId;
    }

    public void setEmailId(String emailId) {
        this.emailId = emailId;
    }

    public String getMobile() {
        return mobile;
    }

    public void setMobile(String mobile) {
        this.mobile = mobile;
    }

    public String getBusinessName() {
        return businessName;
    }

    public void setBusinessName(String businessName) {
        this.businessName = businessName;
    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public Timestamp getCreated() {
        return created;
    }

    public void setCreated(Timestamp created) {
        this.created = created;
    }

    public int getUserType() {
        return userType;
    }

    public void setUserType(int userType) {
        this.userType = userType;
    }

    public int getParentType() {
        return parentType;
    }

    public void setParentType(int parentType) {
        this.parentType = parentType;
    }

    @Override
    public String toString() {
        return "Customer [id=" + id + ", name=" + name + ", emailId=" + emailId + ", mobile=" + mobile
                + ", businessName=" + businessName + ", address=" + address + ", password=" + password + ", created="
                + created + ", userType=" + userType + ", parentType=" + parentType + "]";
     }
   }

Controller -

@RestController
@RequestMapping("/api")
public class CustomerController {

@Autowired
CustomerService customerService;
ResponseHandler response;   

@GetMapping("/customers")
public ResponseEntity<List<Customer>> getCustomers(){
            
    List<Customer> list = customerService.getCustomers();
    return new ResponseEntity<List<Customer>>(list, HttpStatus.OK);
}


@PostMapping(value="/login")
public Customer getCustomer(@RequestParam(value="emailId") String emailId, @RequestParam(value="password") String password) {
    

    Customer theCustomer = customerService.getCustomer(emailId, password);

    if(theCustomer == null) {
        throw new CustomerNotFoundException("Customer not found - "+emailId);
    }
    return theCustomer;
}



@PostMapping(value = "/customers", consumes=MediaType.MULTIPART_FORM_DATA_VALUE)
public Customer saveCustomer(@ModelAttribute Customer customer) {
    
    customerService.saveCustomer(customer);
    return customer;
    }

}

在 Controller 中，您可以getParameterMap()，它将为您提供所有表单数据。

Map<String, String[]> parameterMap = request.getParameterMap();

或者只是将 map 作为参数

@RequestMapping("/yourmapping")
void method(@RequestParam HashMap<String, Object> formData){
   //rest your code
}
