如何修复“ org.springframework.data.redis.serializer.SerializationException”？

Question

  

我正在使用Redis通过springboot和mysql进行缓存。第一次api调用成功响应，但是第二次开始获取异常

     

“例外”：“ org.springframework.data.redis.serializer.SerializationException”

t = Tub(id=20, tare_weight=200)
session.merge(t)
session.commit()

{
    "timestamp": 1567273795394,
    "status": 500,
    "error": "Internal Server Error",
    "exception": "org.springframework.data.redis.serializer.SerializationException",
    "message": "Could not read JSON: Can not construct instance of java.util.ArrayList$SubList: no default no-arguments constructor found\n at [Source: [B@8e02e6; line: 1, column: 56] (through reference chain: java.util.ArrayList[0]); nested exception is com.fasterxml.jackson.databind.JsonMappingException: Can not construct instance of java.util.ArrayList$SubList: no default no-arguments constructor found\n at [Source: [B@8e02e6; line: 1, column: 56] (through reference chain: java.util.ArrayList[0])",
    "path": "/api/loginModule"
}

@SuppressWarnings("unchecked")
    @Cacheable(value = "users", key = "#username")
    public List Login(String username, String password, Integer companyId) throws SerializationException {

    return lastList;
    }
