SpringBoot集成Redis
1.添加redis依赖
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-redis</artifactId></dependency><dependency> <groupId>org.apache.commons</groupId> <artifactId>commons-pool2</artifactId></dependency>2.在application.properties中添加redis配置信息
spring.redis.host=127.0.0.1# Redis服务器连接端口spring.redis.port=6379# Redis服务器连接密码（默认为空）spring.redis.password=# 连接池最大连接数（使用负值表示没有限制）spring.redis.lettuce.pool.max-active=8# 连接池最大阻塞等待时间（使用负值表示没有限制）spring.redis.lettuce.pool.max-wait=-1# 连接池中的最大空闲连接spring.redis.lettuce.pool.max-idle=8# 连接池中的最小空闲连接spring.redis.lettuce.pool.min-idle=0# 连接超时时间（毫秒）spring.redis.timeout=300003.SpringBoot启动类中添加注解配置
@EnableCaching@EnableRedisRepositories//注解开启使用RedisRepositories//CRUD操作将会操作redis中的数据@SpringBootApplicationpublic class RedisApplication { public static void main(String[] args) { SpringApplication.run(RedisApplication.class, args); } }4.创建实体类Entity
@Data@RedisHash("user")//RedisHash非常重要//user表示在redis中新建user集合//之后所有的UserEntity的保存操作全部会保存在user这个集合中//保存时Key的格式为——user：idpublic class UserEntity{ @Id private Long id; private String name; private Integer age; private Date createTime = new Date();}5.创建Dao层——数据操作层
@Repositorypublic interface UserDao extends CrudRepository<UserEntity,Long> {}6.创建Service层——服务层
@Servicepublic class UserService { @Autowired private UserDao userDao; //因为使用了RedisRepositories，所以简单的crud将不用使用RedisTemplate// @Autowired// private RedisTemplate redisTemplate; public void save(UserEntity user){ //redisTemplate.opsForValue().set(new Random().nextDouble() + "",user); userDao.save(user); } public UserEntity findOne(Long id){ //UserEntity user = (UserEntity) redisTemplate.opsForValue().get(key); UserEntity user = userDao.findById(id).get(); return user; }}7.创建Controller层——控制层
@RestController@RequestMapping("user")public class UserController { @Autowired private UserService userService; @GetMapping("save") public String save(){ UserEntity user = new UserEntity(); user.setName(String.valueOf(new Random().nextInt(100000))); user.setAge(new Random().nextInt(100000)); userService.save(user); System.out.println(user.toString()); return "success"; } @GetMapping("find/{id}") public String find(@PathVariable Long id){ UserEntity user = userService.findOne(id); System.out.println(user); return "success"; }}8.redis配置类
@Configurationpublic class RedisConfig { @Bean public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory factory) { RedisTemplate<String, Object> template = new RedisTemplate<String, Object>(); template.setConnectionFactory(factory); Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class); ObjectMapper om = new ObjectMapper(); om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY); om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL); jackson2JsonRedisSerializer.setObjectMapper(om); StringRedisSerializer stringRedisSerializer = new StringRedisSerializer(); // key采用String的序列化方式 template.setKeySerializer(stringRedisSerializer); // hash的key也采用String的序列化方式 template.setHashKeySerializer(stringRedisSerializer); // value序列化方式采用jackson template.setValueSerializer(jackson2JsonRedisSerializer); // hash的value序列化方式采用jackson template.setHashValueSerializer(jackson2JsonRedisSerializer); template.afterPropertiesSet(); return template; }}Redis中的结构为
