SpringBootWeb 篇-深入了解 Redis 五种类型命令与如何在 Java 中操作 Redis

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.stereotype.Component;
 
@Component
public class RedisCommandExample {
 
    @Autowired
    private StringRedisTemplate stringRedisTemplate;
 
    @Autowired
    private RedisTemplate<String, Object> redisTemplate;
 
    public void setStringValue() {
        stringRedisTemplate.opsForValue().set("stringKey", "stringValue");
    }
 
    public void getStringValue() {
        String value = stringRedisTemplate.opsForValue().get("stringKey");
        System.out.println("String Value: " + value);
    }
 
    public void setObjectValue() {
        User user = new User("user1", 25);
        redisTemplate.opsForValue().set("userKey", user);
    }
 
    public void getObjectValue() {
        User user = (User) redisTemplate.opsForValue().get("userKey");
        System.out.println("Object Value: " + user.getName());
    }
 
    public void incrementValue() {
        long newValue = stringRedisTemplate.opsForValue().increment("counterKey", 5);
        System.out.println("Incremented Value: " + newValue);
    }
 
    public void appendValue() {
        stringRedisTemplate.opsForValue().append("stringKey", "AppendValue");
        String value = stringRedisTemplate.opsForValue().get("stringKey");
        System.out.println("Appended Value: " + value);
    }
}
 
class User {
    private String name;
    private int age;
 
    public User(String name, int age) {
        this.name = name;
        this.age = age;
    }
 
    public String getName() {
        return name;
    }
 
    public void setName(String name) {
        this.name = name;
    }
 
    public int getAge() {
        return age;
    }
 
    public void setAge(int age) {
        this.age = age;
    }
}

这个代码示例展示了如何在Spring Boot项目中使用StringRedisTemplate和RedisTemplate<String, Object>操作Redis。其中包含了设置字符串、对象，以及使用Redis的五种基本类型命令（GET, SET, INCR, APPEND）的例子。这些操作可以在任何需要与Redis交互的Spring Boot应用中使用。
