我是靠谱客的博主轻松火车，最近开发中收集的这篇文章主要介绍SpringMVC使用Jedis发布后提示java.lang.ClassNotFoundException: redis.clients.jedis.Jedis问题，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

开发工具：MyEclipse 2017 CI 10

环境：jdk 1.8 , Spring 4.1 , Jedis 2.10

问题代码：

package com.scott.springmvc.restcontroller;

import org.springframework.web.bind.annotation.RequestMapping;
import com.util.RedisUtil;
import org.springframework.web.bind.annotation.*;
import redis.clients.jedis.Jedis;


@RestController
public class Buy {
    private Jedis redis = null;	
	@RequestMapping("/GetRedis")
	public String GetRedisByKey(String key){
		redis = RedisUtil.getJedis();
		System.out.println("Get data from Redis");
		return redis.get(key);
	}
}

发布到MyEclipse tomcat 8.5后，调用提示

上网查询有关java.lang.ClassNotFoundException: redis.clients.jedis.Jedis的问题，或是有关SpringMVC使用使用Jedis的问题（因为本人初次使用SpringMVC和Jedis，所以这么查了），多数提到org.springframework.data及其各种配置方法，经过各种尝试，换版本，问题依旧，突然想到生成没错，也可以成功发布，只是调用出错，说明项目引用没问题，会不会是jedis-2.10.0.jar这个文件没发布到tomcat呢。更改下发布属性试试

右键项目属性

把引部jar文件添加到这列表，重新发布。重新调用上述代码中的方法，MyEclipse Console 会输出F4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".的信息，应该是少某个引用，不过上述错误信息没有，访问Redis也没有问题了。java.lang.ClassNotFoundException: redis.clients.jedis.Jedis 这个问题终于解决。
