SpringBoot整合Redis，redis连接池和RedisTemplate序列化

1、SpringBoot整合redis

1.1 pom.xml

    <dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency><dependency><groupId>junit</groupId><artifactId>junit</artifactId><scope>test</scope></dependency><dependency><groupId>org.mybatis.spring.boot</groupId><artifactId>mybatis-spring-boot-starter</artifactId></dependency><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId></dependency><!--redis相关依赖--><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-redis</artifactId></dependency><dependency><groupId>org.apache.commons</groupId><artifactId>commons-pool2</artifactId></dependency></dependencies>

1.2 application.yml

server:port: 8080spring:datasource:driver-class-name: com.mysql.cj.jdbc.Driverusername: rootpassword: rooturl: jdbc:mysql://127.0.0.1:3306/alarm?useUnicode=true&autoReconnect=true&failOverReadOnly=false&characterEncoding=UTF-8&allowMultiQueries=true&useSSL=false&serverTimezone=Asia/Shanghai&zeroDateTimeBehavior=CONVERT_TO_NULLredis:host: 127.0.0.1port: 6379password:database: 0timeout: 1000mslettuce:pool:max-active: 8 # 连接池最大连接数max-idle: 8 # 连接池最大空闲连接数min-idle: 0 # 连接池最小空闲连接数max-wait: -1ms # 连接池最大阻塞等待时间，负值表示没有限制mybatis:type-aliases-package: cn.yx.zg.pojomapperLocations: classpath:mappers/*.xml

1.3 配置类RedisConfig，实现RedisTemplate序列化

import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.annotation.PropertyAccessor;
import com.fasterxml.jackson.databind.ObjectMapper;
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.serializer.Jackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.RedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;
/*** redisConfig** @author zhanggang* @since 2023/11/18 19:15*/
@Configuration
public class RedisConfig {@Beanpublic RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory factory) {RedisTemplate<String, Object> template = new RedisTemplate<>();RedisSerializer<String> redisSerializer = new StringRedisSerializer();Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);ObjectMapper om = new ObjectMapper ();om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);jackson2JsonRedisSerializer.setObjectMapper(om);template.setConnectionFactory(factory);//key序列化方式template.setKeySerializer(redisSerializer);//value序列化template.setValueSerializer(jackson2JsonRedisSerializer);//key hashmap序列化template.setHashKeySerializer (redisSerializer);//value hashmap序列化template.setHashValueSerializer(jackson2JsonRedisSerializer);return template;}
}

1.4 代码测试

import cn.yx.zg.SpringBootMybatisApplication;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.test.context.junit4.SpringRunner;/*** @author zhanggang* @since 2023/11/21 10:29*/
@SpringBootTest(classes = SpringBootMybatisApplication.class)
@RunWith(SpringRunner.class)
public class RedisTest {@Autowiredprivate RedisTemplate redisTemplate;@Autowiredprivate StringRedisTemplate stringRedisTemplate;@Testpublic void testRedis01() {redisTemplate.opsForValue().set("name", "zg");}
}

2、SpringBoot整合redis几个疑问？

2.2、redisTemplate和stringRedisTemplate
