@Cacheable中condition的问题

Question

不加condition = "#result.code!=500"可以正常运行，加了之后就报错，是我写得有问题吗

    @Autowired
    private GlassService glassService;

    @GetMapping("/list")
    @Cacheable(value = "glass",key = "'getGlass'",condition = "#result.code!=500")
    public Result getGlass(){
        List<Glass> list = glassService.list(null);
        return list!=null? Result.success(200,"响应成功",list) :
                Result.error(500,"响应失败");
    }

Answer 1

在condition中，无法获取#result，你可以用unless，反转下条件就行了。
