springdata redis怎样配置

要配置Spring Data Redis，你需要遵循以下步骤：

1. 添加依赖

在你的项目中，添加Spring Boot和Spring Data Redis的依赖。对于Maven项目，将以下依赖添加到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>

对于Gradle项目，将以下依赖添加到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连接

在application.properties或application.yml文件中，配置Redis连接信息。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. 创建Redis配置类

创建一个配置类，用于初始化RedisTemplate和StringRedisTemplate。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

在你的服务类中，注入RedisTemplate或StringRedisTemplate，然后使用它们执行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);

    }

}
    

现在你已经成功配置了Spring Data Redis，并可以使用RedisTemplate和StringRedisTemplate执行Redis操作。
