SpringBoot整合Mybatis和Redis

好的，以下是SpringBoot整合Mybatis和Redis的步骤：

1. 在pom.xml中引入Mybatis和Redis的依赖：

<dependency>
    <groupId>org.mybatis.spring.boot</groupId>
    <artifactId>mybatis-spring-boot-starter</artifactId>
    <version>${mybatis-spring-boot-starter.version}</version>
</dependency>

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>

2. 在application.properties中配置Mybatis和Redis相关的参数：

# Mybatis配置
mybatis.mapper-locations=classpath:mapper/*.xml
mybatis.type-aliases-package=com.example.demo.model

# Redis配置
spring.redis.host=localhost
spring.redis.port=6379

3. 编写Mybatis的Mapper接口和对应的SQL语句：

@Mapper
public interface UserMapper {
    @Select("SELECT id, name, age FROM user WHERE id=#{id}")
    User getUserById(@Param("id") Integer id);
}

4. 编写Redis的配置类和RedisTemplate实例：

@Configuration
public class RedisConfig {
    @Bean
    public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {
        RedisTemplate<String, Object> redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(redisConnectionFactory);
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.setValueSerializer(new GenericJackson2JsonRedisSerializer());
        return redisTemplate;
    }
}

5. 在Service中使用Mybatis和Redis：

@Service
public class UserService {
    @Autowired
    private UserMapper userMapper;

    @Autowired
    private RedisTemplate<String, Object> redisTemplate;

    public User getUserById(Integer id) {
        String key = "user_" + id;
        User user = (User) redisTemplate.opsForValue().get(key);
        if (user == null) {
            user = userMapper.getUserById(id);
            redisTemplate.opsForValue().set(key, user);
        }
        return user;
    }
}

以上就是SpringBoot整合Mybatis和Redis的步骤，希望能够帮助到你。
