问题：
使用lua脚本释放锁时，lua 脚本中返回值为 int 时出现异常，但是将返回值修改为 string 时却能正常使用
错误信息如下：

原有：
org.springframework.data.redis.connection.ReturnType , 这里面redis没有对应的Integer ,只有使用Long
代码：
public static ReturnType fromJavaType(@Nullable Class<?> javaType) {
if (javaType == null) {
return ReturnType.STATUS;
}
if (javaType.isAssignableFrom(List.class)) {
return ReturnType.MULTI;
}
if (javaType.isAssignableFrom(Boolean.class)) {
return ReturnType.BOOLEAN;
}
if (javaType.isAssignableFrom(Long.class)) {
return ReturnType.INTEGER;
}
return ReturnType.VALUE;
}
