bug描述:
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name ‘assetChangeOrderController’: Unsatisfied dependency expressed through field ‘redisTemplate’; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name ‘redisTemplate’ defined in class path resource [com/rdl/rterp/config/RedisConfig.class]: Unsatisfied dependency expressed through method ‘redisTemplate’ parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘redisConnectionFactory’ defined in class path resource [org/springframework/boot/autoconfigure/data/redis/JedisConnectionConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.data.redis.connection.jedis.JedisConnectionFactory]: Factory method ‘redisConnectionFactory’ threw exception; nested exception is java.lang.NoClassDefFoundError: redis/clients/jedis/util/SafeEncoder
解决办法:
引入正确的jedis依赖版本
<!-- redis依赖--><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-redis</artifactId></dependency><dependency><groupId>redis.clients</groupId><artifactId>jedis</artifactId><version>3.7.0</version> <!-- 使用适合你的项目的版本 --></dependency>
yaml配置文件:
#连接的spring.redisredis:port: 6379host: 172.16.1.254timeout: 5000password:database: 14jedis:pool:max-active: 10max-wait: -1msmax-idle: 8 #空闲min-idle: 0client-type: jedis
config包RedisConfig 配置文件
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.GenericJackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;@Configuration
public class RedisConfig {@Beanpublic RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory connectionFactory) {RedisTemplate<String, Object> template = new RedisTemplate<>();template.setConnectionFactory(connectionFactory);template.setKeySerializer(new StringRedisSerializer());template.setValueSerializer(new GenericJackson2JsonRedisSerializer());return template;}
}
最后成功启动spring boot项目
