要使用Spring Boot创建一个公园门票预订系统,你可以按照以下步骤进行:
1. **设置项目结构**[^1]:
- 创建一个新的Spring Boot项目,选择Web支持,这会自动生成`src/main/java`目录下的基本文件结构。
- 添加Thymeleaf模板引擎到`pom.xml`中:
```xml
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
```
2. **数据库配置**:
- 如果还没有MySQL数据库,先安装并配置。在`application.properties`中添加MySQL连接信息:
```
spring.datasource.url=jdbc:mysql://localhost:3306/park_tickets
spring.datasource.username=your_username
spring.datasource.password=your_password
```
3. **创建数据模型**:
```java
@Entity
public class Ticket {
private String parkName;
private LocalDate date;
private double price;
// getters and setters...
}
```
4. **Repository接口**:
```java
public interface TicketRepository extends JpaRepository<Ticket, Long> {
List<Ticket> findByParkNameAndDate(String parkName, LocalDate date);
}
```
5. **Service层**:
```java
public class TicketService {
private final TicketRepository repository;
public TicketService(TicketRepository repository) {
this.repository = repository;
}
// 方法实现如新增、修改、删除和查询操作
public Ticket createTicket(Ticket ticket) { ... }
public void updateTicket(Ticket ticket) { ... }
public void deleteTicket(Long id) { ... }
public List<Ticket> searchTickets(String parkName, LocalDate date) { return repository.findByParkNameAndDate(parkName, date); }
}
```
6. **Controller层**:
```java
@RestController
@RequestMapping("/tickets")
public class TicketController {
private final TicketService service;
public TicketController(TicketService service) {
this.service = service;
}
@GetMapping
public ModelAndView listTickets(@RequestParam(defaultValue = "") String parkName, @RequestParam(defaultValue = "now") LocalDate date) {
// 使用Thymeleaf模板渲染结果
return new ModelAndView("tickets/list", "tickets", service.searchTickets(parkName, date));
}
// 其他HTTP方法对应相应的方法实现
}
```
7. **Thymeleaf模板**:
- 在`templates/tickets/list.html`中编写HTML表单和结果展示:
```html
<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
...
<table>
<tr th:each="ticket : ${tickets}">
<!-- 表格列对应Ticket对象属性 -->
</tr>
</table>
...
</html>
```
8. **路由和页面跳转**:
- 调整`webMvcConfigurer`类以启用默认的`ThymeleafViewResolver`:
```java
@Configuration
public class WebConfig implements WebMvcConfigurer {
@Override
public void configureViewResolvers(ViewResolverRegistry registry) {
registry.viewResolver().prefix("/templates/").suffix(".html");
}
}
```
完成后,你可以通过访问`/tickets`路径来查看和管理公园门票。每个HTTP请求(GET、POST等)都将映射到对应的Controller方法。
