springboot中使用spring-data-redis出现Caused by: java.lang.ClassNotFoundException: redis.clients.jedis.JedisPoolConfig
在maven的配置如下：
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-redis</artifactId> <version>2.0.4.RELEASE</version> </dependency>
启动测试类的时候，总是出现如下异常；
Caused by: java.lang.NoClassDefFoundError: redis/clients/jedis/JedisPoolConfig at java.base/java.lang.Class.getDeclaredMethods0(Native Method) at java.base/java.lang.Class.privateGetDeclaredMethods(Class.java:3139) at java.base/java.lang.Class.getDeclaredMethods(Class.java:2266) at org.springframework.util.ReflectionUtils.getDeclaredMethods(ReflectionUtils.java:641) ... 78 more Caused by: java.lang.ClassNotFoundException: redis.clients.jedis.JedisPoolConfig at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1309) at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1138) ... 82 more
解决：
修改成如下配置：
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-redis</artifactId> <exclusions> <exclusion> <groupId>io.lettuce</groupId> <artifactId>lettuce-core</artifactId> </exclusion> </exclusions> </dependency> <dependency> <groupId>redis.clients</groupId> <artifactId>jedis</artifactId> </dependency>
为什么？看友人翻译
JedisPoolConfig is needed when we use Jedis Configuration. In Spring Boot 2.0, spring-boot-starter-data-redis gives Lettuce dependency by default instead of Jedis. To use Jedis configuration, exclude Lettuce and add Jedis as following.
