好的,下面是一个简单的使用Spring Boot + MyBatis + JSP实现注册功能的示例。
首先,需要在pom.xml文件中添加以下依赖:
```xml
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.mybatis.spring.boot</groupId>
<artifactId>mybatis-spring-boot-starter</artifactId>
<version>2.1.4</version>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
</dependency>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
</dependency>
```
接着,在application.properties文件中配置数据库连接信息:
```
spring.datasource.url=jdbc:mysql://localhost:3306/mydb?useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTC
spring.datasource.username=root
spring.datasource.password=123456
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
mybatis.mapper-locations=classpath:mapper/*.xml
mybatis.type-aliases-package=com.example.demo.entity
```
然后,创建一个用户实体类User:
```java
public class User {
private Integer id;
private String username;
private String password;
// 省略getter和setter方法
}
```
接着,创建一个MyBatis的Mapper接口UserMapper:
```java
@Mapper
public interface UserMapper {
void insert(User user);
}
```
然后,创建一个UserController类来处理用户的注册请求:
```java
@Controller
public class UserController {
@Autowired
private UserMapper userMapper;
@RequestMapping("/register")
public String register(User user) {
userMapper.insert(user);
return "register_success";
}
}
```
最后,创建一个register.jsp页面来显示用户注册的表单:
```jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>用户注册</title>
</head>
<body>
<h1>用户注册</h1>
<form action="${pageContext.request.contextPath}/register" method="post">
用户名:<input type="text" name="username" /><br />
密码:<input type="password" name="password" /><br />
<input type="submit" value="注册" />
</form>
</body>
</html>
```
在完成上述配置后,启动Spring Boot应用程序,访问http://localhost:8080/register即可看到用户注册页面,填写表单后点击“注册”按钮即可完成用户注册。
