6.1、引入redis的maven配置
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
6.2、application.properties中配置redis信息
spring.redis.host=192.168.200.129
spring.redis.port=6379
#spring.redis.password=root
spring.redis.timeout=60000
spring.redis.database=0
6.3、使用RedisTemplate工具类操作redis
springboot中使用RedisTemplate来操作redis,需要在我们的bean中注入这个对象,代码如下:
@Autowired
private RedisTemplate<String, String> redisTemplate;
// 用下面5个对象来操作对应的类型
this.redisTemplate.opsForValue(); //提供了操作string类型的所有方法
this.redisTemplate.opsForList(); // 提供了操作list类型的所有方法
this.redisTemplate.opsForSet(); //提供了操作set的所有方法
this.redisTemplate.opsForHash(); //提供了操作hash表的所有方法
this.redisTemplate.opsForZSet(); //提供了操作zset的所有方法
6.4、RedisTemplate示例代码
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import java.util.Set;
@RestController
@RequestMapping("/redis")
public class RedisController {
@Autowired
private RedisTemplate<String, String> redisTemplate;
@RequestMapping("/stringTest")
public String stringTest() {
this.redisTemplate.delete("name");
this.redisTemplate.opsForValue().set("name", "路人");
String name = this.redisTemplate.opsForValue().get("name");
return name;
}
@RequestMapping("/listTest")
public List<String> listTest() {
this.redisTemplate.delete("names");
this.redisTemplate.opsForList().rightPushAll("names", "刘德华", "张学友", "郭富城", "黎明");
List<String> courses = this.redisTemplate.opsForList().range("names", 0, -1);
return courses;
}
@RequestMapping("setTest")
public Set<String> setTest() {
this.redisTemplate.delete("courses");
this.redisTemplate.opsForSet().add("courses", "java", "spring", "springboot");
Set<String> courses = this.redisTemplate.opsForSet().members("courses");
return courses;
}
@RequestMapping("hashTest")
public Map<Object, Object> hashTest() {
this.redisTemplate.delete("userMap");
Map<String, String> map = new HashMap<>();
map.put("name", "路人");
map.put("age", "30");
this.redisTemplate.opsForHash().putAll("userMap", map);
Map<Object, Object> userMap = this.redisTemplate.opsForHash().entries("userMap");
return userMap;
}
@RequestMapping("zsetTest")
public Set<String> zsetTest() {
this.redisTemplate.delete("languages");
this.redisTemplate.opsForZSet().add("languages", "java", 100d);
this.redisTemplate.opsForZSet().add("languages", "c", 95d);
this.redisTemplate.opsForZSet().add("languages", "php", 70);
Set<String> languages = this.redisTemplate.opsForZSet().range("languages", 0, -1);
return languages;
}
}
