尝试创建一个简单的站点来显示我的 MySql 数据库中的内容。我用松散地尝试这个词哈哈。注意我有“/all”的页面,我用它来检查我的列表是否为空。我想弄清楚为什么我的列表是空的并且没有存储我的数据库的内容?
MySql:
CREATE DATABASE IF NOT EXISTS `web_customer_tracker`;
USE `web_customer_tracker`;
DROP TABLE IF EXISTS `customer`;
CREATE TABLE `customer`(
`id` INT(11) NOT NULL auto_increment,
`first_name` VARCHAR(45) DEFAULT NULL,
`last_name` VARCHAR(45)DEFAULT NULL,
`email` VARCHAR(45) DEFAULT NULL,
PRIMARY KEY(`id`)
) ENGINE=INNODB AUTO_INCREMENT=1 CHARSET=latin1;
INSERT INTO `customer` VALUES
(1, 'David', 'Adams', 'david@luv2code.com'),
(2, 'John', 'Die', 'john@luv2code.com'),
(3, 'Ajay', 'Rao', 'ajay@luv2code.com'),
(4, 'Mary', 'Publiidc', 'mary@luv2code.com'),
(5, 'Maxwell', 'Dixon', 'maxwell@luv2code.com');
实体:
@Entity
@Table(name = "customer")
public class Customer implements Serializable {
@Column(name = "id")
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private int id;
@Column(name = "first_name")
private String firstName;
@Column(name = "last_name")
private String lastName;
@Column(name = "email")
private String email;
public Customer(){}
public Customer(String firstName, String lastName, String company){
this.firstName = firstName;
this.lastName = lastName;
this.email = company;
}
@Override
public String toString() {
return "Customer{" +
"id=" + id +
", firstName='" + firstName + '\'' +
", lastName='" + lastName + '\'' +
", email='" + email + '\'' +
'}';
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
public String getCompany() {
return email;
}
public void setCompany(String company) {
this.email = company;
}
}
道
@Repository
@Transactional
public interface CustomerDAO extends CrudRepository<Customer, String> {
public List<Customer> findAll();
}
实现:
@Transactional
@Repository
public abstract class CustomerDAOImpl implements CustomerDAO {
private CustomerDAO customerDAO;
@Override
public List<Customer> findAll() {
return customerDAO.findAll();
}
}
Controller :
@Controller
public class CustomerController {
@Autowired
private CustomerDAO customerDAO;
public String string;
@RequestMapping(value = "/list")
public String listCustomers(Model model){
List<Customer> customers = customerDAO.findAll();
String string = customers.get(1).toString();
model.addAttribute("text", string);
model.addAttribute("customers", customers);
return "list-customers";
}
@RequestMapping(value = "/all")
@ResponseBody
public String get() {
List<Customer> customers = customerDAO.findAll();
String names;
if(customers.isEmpty() == true){
names = "This is empty";
} else {
names = "Something is in here";
}
return names;
}
}

最佳答案
要事第一,
确保您已完成以下操作。
<Customer,String>
至 <Customer,Integer>
@Transactional
和 @Repository
, 它们不是必需的。其余代码看起来还不错。尝试上述步骤。
谢谢
