今天自己测试了一下，往redis中存数据，代码没有报错，为什么redis中key乱码且看不到值，求解

Question

package com.service;

public interface StudentService {

    void put(String key, String value);
}

package com.service.impl;

import com.service.StudentService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.stereotype.Service;

@Service
public class StudentServiceImpl implements StudentService {

    @Autowired
    private RedisTemplate<Object,Object> redisTemplate;

    @Override
    public void put(String key, String value) {

        redisTemplate.opsForValue().set(key,value);
    }
}

package com.web;

import com.service.StudentService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
public class StudentController {

    @Autowired
    private StudentService studentService;

    @RequestMapping(value = "/put")
    @ResponseBody
    public Object put(String key,String value){

        studentService.put(key,value);
        return "值已成功放入redis";
    }

}

你这个key和value是不是前端传的，你试一下在代码中写死key和value，看下存进去会不会变成乱码，如果不会，说明是前后端传值造成的，如果不会，再排查原因
