要配置Spring Data Redis,你需要遵循以下步驟:

  1. 添加依賴

在你的項(xiàng)目中,添加Spring Boot和Spring Data Redis的依賴。對(duì)于Maven項(xiàng)目,將以下依賴添加到pom.xml文件中:

<dependencies>
    <!-- Spring Boot Starter Data Redis -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-redis</artifactId>
    </dependency>

    <!-- Redisson for distributed locks and other features -->
    <dependency>
        <groupId>org.redisson</groupId>
        <artifactId>redisson</artifactId>
        <version>3.16.4</version>
    </dependency>

    <!-- Other dependencies -->
</dependencies>

對(duì)于Gradle項(xiàng)目,將以下依賴添加到build.gradle文件中:

dependencies {
    // Spring Boot Starter Data Redis
    implementation 'org.springframework.boot:spring-boot-starter-data-redis'

    // Redisson for distributed locks and other features
    implementation 'org.redisson:redisson:3.16.4'

    // Other dependencies
}
  1. 配置Redis連接

application.propertiesapplication.yml文件中,配置Redis連接信息。例如:

# application.properties
spring.redis.host=localhost
spring.redis.port=6379
spring.redis.password=
spring.redis.database=0
spring.redis.timeout=60000

或者

# application.yml
spring:
  redis:
    host: localhost
    port: 6379
    password: 
    database: 0
    timeout: 60000
  1. 創(chuàng)建Redis配置類

創(chuàng)建一個(gè)配置類,用于初始化RedisTemplateStringRedisTemplate。例如:

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.data.redis.serializer.GenericJackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;

@Configuration
public class RedisConfig {

    @Bean
    public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory factory) {
        RedisTemplate<String, Object> template = new RedisTemplate<>();
        template.setConnectionFactory(factory);
        template.setKeySerializer(new StringRedisSerializer());
        template.setValueSerializer(new GenericJackson2JsonRedisSerializer());
        template.afterPropertiesSet();
        return template;
    }

    @Bean
    public StringRedisTemplate stringRedisTemplate(RedisConnectionFactory factory) {
        StringRedisTemplate template = new StringRedisTemplate();
        template.setConnectionFactory(factory);
        template.setKeySerializer(new StringRedisSerializer());
        template.setValueSerializer(new StringRedisSerializer());
        template.afterPropertiesSet();
        return template;
    }
}
  1. 使用RedisTemplate和StringRedisTemplate

在你的服務(wù)類中,注入RedisTemplateStringRedisTemplate,然后使用它們執(zhí)行Redis操作。例如:

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.stereotype.Service;

@Service
public class MyService {

    @Autowired
    private RedisTemplate<String, Object> redisTemplate;

    public void saveData(String key, Object value) {
        redisTemplate.opsForValue().set(key, value);
    }

    public Object getData(String key) {
        return redisTemplate.opsForValue().get(key);
    }
}

現(xiàn)在你已經(jīng)成功配置了Spring Data Redis,并可以使用RedisTemplateStringRedisTemplate執(zhí)行Redis操作。
