问题环境：SpringBoot 连接redis  集群

1.启动引导类：

package com.zengjx;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
 * @ClassName HelloController
 * @Description TODO
 * @Author zengjx
 * @Company zengjx
 * @Date 2019/12/6  14:38
 * @Version V1.0
 */
@SpringBootApplication
public class RedisDemoApplication {


    public static void main(String[] args) {
        SpringApplication.run(RedisDemoApplication.class);

    }
}

2.配置文件：appliction.yml

spring:
  datasource:
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://192.168.211.132:3306/changgou_user?useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTC
    username: root
    password: 123456
  application:
    name: redis-demo
  #redis配置
  redis:
    cluster:
      nodes:
        - 192.168.211.132:7001
        - 192.168.211.132:7002
        - 192.168.211.132:7003
        - 192.168.211.132:7004
        - 192.168.211.132:7005
        - 192.168.211.132:7006
server:
  ssl:
    enabled: false
  port: 9008
mybatis:
  configuration:
    map-underscore-to-camel-case: true

3. 测试类

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;

import javax.annotation.Resource;

/**
 * @ClassName HelloController
 * @Description TODO
 * @Author zengjx
 * @Company zengjx
 * @Date 2019/12/6  14:39
 * @Version V1.0
 */
@SpringBootTest(classes = RedisDemoApplicationTests.class)
@RunWith(SpringRunner.class)
public class RedisDemoApplicationTests {

    @Autowired
   // @Resource
    RedisTemplate<String, Object> redisTemplate;
    @Test
    public void contextLoads() {
        redisTemplate.boundValueOps("name").set("zengjx");
        System.out.println(redisTemplate.boundValueOps("name").get());
    }


}

 4.  运行测试类出现问题

 

Description:

Field redisTemplate in RedisDemoApplicationTests required a bean of type 'org.springframework.data.redis.core.RedisTemplate' that could not be found.

The injection point has the following annotations:
	- @org.springframework.beans.factory.annotation.Autowired(required=true)


Action:

Consider defining a bean of type 'org.springframework.data.redis.core.RedisTemplate' in your configuration.

5.网上的一些解决方法

• @Resource

https://blog.csdn.net/weixin_33913332/article/details/92395338

• RedisTemplate< String, Object>注入

 https://blog.csdn.net/zhaoheng314/article/details/81564166

6.解决方法

原因是aplication.yml   redis 密码要改成 root  

问题1；测试类没有在一个包里面 

问题2:@SpringBootTest(启动类.class)
