springboot+Mybatis+Redis项目搭建（非常适合新上手springboot或不经常用java写后端的朋友）

以下是一个简化的Spring Boot + MyBatis + Redis项目的基本架构示例：

1. 在pom.xml中添加依赖：

<dependencies>
    <!-- Spring Boot Starter -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter</artifactId>
    </dependency>
 
    <!-- Spring Boot Starter for Redis -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-redis</artifactId>
    </dependency>
 
    <!-- Spring Boot Starter for MyBatis -->
    <dependency>
        <groupId>org.mybatis.spring.boot</groupId>
        <artifactId>mybatis-spring-boot-starter</artifactId>
        <version>2.1.4</version>
    </dependency>
 
    <!-- Database Driver -->
    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <scope>runtime</scope>
    </dependency>
 
    <!-- Spring Boot Starter Test -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>
</dependencies>

2. 配置application.properties或application.yml：

spring.datasource.url=jdbc:mysql://localhost:3306/your_database
spring.datasource.username=your_username
spring.datasource.password=your_password
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
 
mybatis.mapper-locations=classpath:mapper/*.xml
mybatis.type-aliases-package=com.yourpackage.model
 
spring.redis.host=localhost
spring.redis.port=6379

3. 创建一个Redis配置类：

@Configuration
public class RedisConfig {
 
    @Bean
    public CacheManager cacheManager(RedisConnectionFactory redisConnectionFactory) {
        return RedisCacheManager.builder(RedisCacheWriter.nonLockingRedisCacheWriter(redisConnectionFactory))
            .cacheDefaults(CacheConfiguration.defaultCacheConfig())
            .build();
    }
}

4. 创建一个MyBatis的Mapper接口：

@Mapper
public interface YourModelMapper {
    // 定义操作数据库的方法
}

5. 创建一个Service层：

@Service
public class YourModelService {
    
    @Autowired
    private YourModelMapper yourModelMapper;
    
    @Cacheable("yourCacheName")
    public YourModel getById(Integer id) {
        return yourModelMapper.selectByPrimaryKey(id);
