一、引入依赖及进行配置
1.maven依赖的引入（继承了SpringBoot的父模块，所以不需要再声明版本）
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>2.application.yml配置
spring:
redis:
host: localhost
port: 6379
password:
database: 0 # 指定redis的分库(共16个,0-15)二、使用
使用示例:
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.web.bind.annotation.*;
@RestController
@RequestMapping("/user")
public class UserController {
@Autowired
private RedisTemplate redisTemplate;
@GetMapping("/get")
public Object getUser() {
return redisTemplate.opsForValue().get("user");
}
@GetMapping("/set")
public String setUser(String user) {
redisTemplate.opsForValue().set("user", user);
return "success";
}
}主要是自动装配好redis依赖提供给我们的RedisTemplate，然后通过redisTemplate来进行get和set的操作

三、Redis 操作工具类的封装
redis相应的工具类封装，主要是对各种数据类型操作更方便，设置缓存过期时间等。
utils.RedisCache:
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.BoundSetOperations;
import org.springframework.data.redis.core.HashOperations;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.core.ValueOperations;
import org.springframework.stereotype.Component;
import java.util.*;
import java.util.concurrent.TimeUnit;
@Component
public class RedisCache {
@Autowired
public RedisTemplate redisTemplate;
public <T> void setCacheObject(final String key, final T value) {
redisTemplate.opsForValue().set(key, value);
}
public <T> void setCacheObject(final String key, final T value, final Integer timeout, final TimeUnit timeUnit) {
redisTemplate.opsForValue().set(key, value, timeout, timeUnit);
}
public boolean expire(final String key, final long timeout) {
return expire(key, timeout, TimeUnit.SECONDS);
}
public boolean expire(final String key, final long timeout, final TimeUnit unit) {
return redisTemplate.expire(key, timeout, unit);
}
public <T> T getCacheObject(final String key) {
ValueOperations<String, T> operation = redisTemplate.opsForValue();
return operation.get(key);
}
public boolean deleteObject(final String key) {
return redisTemplate.delete(key);
}
public long deleteObject(final Collection collection) {
return redisTemplate.delete(collection);
}
public <T> long setCacheList(final String key, final List<T> dataList) {
Long count = redisTemplate.opsForList().rightPushAll(key, dataList);
return count == null ? 0 : count;
}
public <T> List<T> getCacheList(final String key) {
return redisTemplate.opsForList().range(key, 0, -1);
}
public <T> BoundSetOperations<String, T> setCacheSet(final String key, final Set<T> dataSet) {
BoundSetOperations<String, T> setOperation = redisTemplate.boundSetOps(key);
Iterator<T> it = dataSet.iterator();
while (it.hasNext()) {
setOperation.add(it.next());
}
return setOperation;
}
public <T> Set<T> getCacheSet(final String key) {
return redisTemplate.opsForSet().members(key);
}
public <T> void setCacheMap(final String key, final Map<String, T> dataMap) {
if (dataMap != null) {
redisTemplate.opsForHash().putAll(key, dataMap);
}
}
public <T> Map<String, T> getCacheMap(final String key) {
return redisTemplate.opsForHash().entries(key);
}
public <T> void setCacheMapValue(final String key, final String hKey, final T value) {
redisTemplate.opsForHash().put(key, hKey, value);
}
public <T> T getCacheMapValue(final String key, final String hKey) {
HashOperations<String, String, T> opsForHash = redisTemplate.opsForHash();
return opsForHash.get(key, hKey);
}
public void incrementCacheMapValue(String key, String hKey, int v) {
redisTemplate.opsForHash().increment(key, hKey, v);
}
public void delCacheMapValue(final String key, final String hkey) {
HashOperations hashOperations = redisTemplate.opsForHash();
hashOperations.delete(key, hkey);
}
public <T> List<T> getMultiCacheMapValue(final String key, final Collection<Object> hKeys) {
return redisTemplate.opsForHash().multiGet(key, hKeys);
}
public Collection<String> keys(final String pattern) {
return redisTemplate.keys(pattern);
}
}使用:
import com.jk.utils.RedisCache;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;
@RestController
@RequestMapping("/user")
public class UserController {
@Autowired
private RedisCache redisCache;
@GetMapping("/get")
public Object getUser() {
return redisCache.getCacheObject("user");
}
@GetMapping("/set")
public String setUser(String user) {
redisCache.setCacheObject("user", user);
return "success";
}
