Redis专题第6篇：SpringBoot2整合Redis-Java充电社【公众号：Java充电社】

## 6.1、引入redis的maven配置

```xml
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
```

## 6.2、application.properties中配置redis信息

```properties
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：

```java
@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

```java
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;
    }
}
```
