SpringBoot+mysql+Redis 整合

整合Spring Boot, MySQL和Redis主要涉及以下几个步骤：

1. 在pom.xml中添加Spring Boot Starter Data Redis和MySQL的依赖。
2. 配置application.properties或application.yml文件，包括数据库连接信息和Redis连接信息。
3. 创建实体类和Repository接口。
4. 配置Redis缓存。
5. 使用Redis和MySQL。

以下是一个简化的示例：

pom.xml依赖配置：

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jpa</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-redis</artifactId>
    </dependency>
    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <scope>runtime</scope>
    </dependency>
</dependencies>

application.properties配置：

spring.datasource.url=jdbc:mysql://localhost:3306/yourdb?useSSL=false
spring.datasource.username=root
spring.datasource.password=yourpassword
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
 
spring.redis.host=localhost
spring.redis.port=6379
 
spring.jpa.hibernate.ddl-auto=update
spring.jpa.show-sql=true

实体类和Repository：

@Entity
public class User {
    @Id
    private Long id;
    private String name;
    // getters and setters
}
 
public interface UserRepository extends JpaRepository<User, Long> {
    User findByName(String name);
}

Redis配置：

@Configuration
public class RedisConfig extends CachingConfigurerSupport {
    @Bean
    public RedisTemplate<String, Object> redisTemplate(LettuceConnectionFactory lettuceConnectionFactory) {
        final RedisTemplate<String, Object> template = new RedisTemplate<>();
        template.setConnectionFactory(lettuceConnectionFactory);
        return template;
    }
}

Service层使用Redis和MySQL：

@Service
public class UserService {
 
    @Autowired
    private UserRepository userRepository;
 
    @Autowired
    private StringRedisTemplate redisTemplate;
 
    @Cacheable(value = "users", key = "#name")
    public User findByName(String name) {
        // Try to get user from
