Spring Boot (二) 整合 Redis

前言

本文将会基于 springboot 2.1.8.RELEASE 简单整合 Redis ,适合新手小白入门

Spring Boot 整合 Redis 入门

1、pom.xml 中引入 redis 依赖

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

2、application.yml 配置文件中配置Redis连接参数等

spring:
# Redis数据源
redis:
# Redis数据库索引(默认为0)
database: 0
# Redis服务器地址
host: 127.0.0.1
# Redis服务器连接端口
port: 6379
# 连接超时时间(毫秒
timeout: 6000
# Redis服务器连接密码(默认为空)
password:
jedis:
pool:
max-active: 1000 # 连接池最大连接数(使用负值表示没有限制)
max-wait: -1 # 连接池最大阻塞等待时间(使用负值表示没有限制)
max-idle: 10 # 连接池中的最大空闲连接
min-idle: 5 # 连接池中的最小空闲连接

3、Redis核心配置类

温馨小提示: 在这里注意设置key和value的序列化方式,否则存到redis里的数据会乱码

@Configuration
public class RedisConfig { @Bean
@SuppressWarnings("all")
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;
} }

4、简单测试

@RestController
@RequestMapping("/api")
@Api(description = "测试-接口")
public class IndexController extends BaseController { private final String key = "sysLog"; @Autowired
private ILogService logService; @Autowired
RedisTemplate redisTemplate; @PostMapping(value = "/saveData", produces = "application/json;charset=utf-8")
@ApiOperation(value = "保存数据", httpMethod = "POST", response = ApiResult.class)
public ApiResult saveData(@RequestBody SysLog sysLog) {
List<SysLog> sysLogList = logService.selectList(null);
redisTemplate.opsForValue().set(key, sysLogList);
return ApiResult.ok("SUCCESS");
} @GetMapping(value = "/getData", produces = "application/json;charset=utf-8")
@ApiOperation(value = "获取数据", httpMethod = "GET", response = ApiResult.class)
public ApiResult getData() {
List<SysLog> result = (List<SysLog>) redisTemplate.opsForValue().get(key);
return ApiResult.ok("SUCCESS", result);
} }
