要通过Spring和MyBatis依赖并运用Thymeleaf模板技术将数据库中的表格显示在HTML页面上,你可以按照以下步骤实现:
1. 在pom.xml文件中添加Spring Boot、MyBatis和Thymeleaf的相关依赖:
```xml
<dependencies>
<!-- Spring Boot dependencies -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<!-- MyBatis dependencies -->
<dependency>
<groupId>org.mybatis.spring.boot</groupId>
<artifactId>mybatis-spring-boot-starter</artifactId>
<version>2.2.0</version>
</dependency>
<dependency>
<groupId>com.h2database</groupId>
<artifactId>h2</artifactId>
<version>1.4.200</version>
</dependency>
<!-- Thymeleaf dependencies -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
</dependencies>
```
2. 在application.properties配置文件中配置数据库和MyBatis的相关参数:
```properties
# Data Source Configuration
spring.datasource.driverClassName=org.h2.Driver
spring.datasource.url=jdbc:h2:mem:testdb
spring.datasource.username=sa
spring.datasource.password=
# MyBatis Configuration
mybatis.mapper-locations=classpath:mapper/*.xml
mybatis.type-aliases-package=com.example.demo.domain
```
3. 创建数据库表格对应的实体类,并在MyBatis的映射文件中编写SQL语句:
```java
package com.example.demo.domain;
public class User {
private Long id;
private String name;
private Integer age;
// Getters and Setters
}
```
```xml
<!-- /src/main/resources/mapper/UserMapper.xml -->
<mapper namespace="com.example.demo.mapper.UserMapper">
<select id="selectAll" resultType="com.example.demo.domain.User">
SELECT * FROM user
</select>
</mapper>
```
4. 创建MyBatis的Mapper接口:
```java
package com.example.demo.mapper;
import com.example.demo.domain.User;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Select;
import java.util.List;
@Mapper
public interface UserMapper {
@Select("SELECT * FROM user")
List<User> selectAll();
}
```
5. 在Spring Boot项目中创建Controller,并在其方法中调用MyBatis的Mapper接口获取数据,并将数据传递给Thymeleaf模板:
```java
package com.example.demo.controller;
import com.example.demo.mapper.UserMapper;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
@Controller
public class UserController {
private final UserMapper userMapper;
public UserController(UserMapper userMapper) {
this.userMapper = userMapper;
}
@GetMapping("/")
public String index(Model model) {
model.addAttribute("users", userMapper.selectAll());
return "index";
}
}
```
6. 创建Thymeleaf模板,并在其中使用Thymeleaf标签和表达式来显示数据:
```html
<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8">
<title>User List</title>
</head>
<body>
<table>
<thead>
<tr>
<th>ID</th>
<th>Name</th>
<th>Age</th>
</tr>
</thead>
<tbody>
<tr th:each="user : ${users}">
<td th:text="${user.id}"></td>
<td th:text="${user.name}"></td>
<td th:text="${user.age}"></td>
</tr>
</tbody>
</table>
</body>
</html>
```
以上就是通过Spring和MyBatis依赖并运用Thymeleaf模板技术将数据库中的表格显示在HTML页面上的基本步骤,你可以根据实际需求进行调整和扩展。
