Spring控制器未获取缓存控制标头

Question

我想在缓存控制头中设置max age以响应。我已经写了如下，但仍然有max-age 0。我想只为一种方法设置max age，所以我不想禁用默认值。我认为应该是ovveride。

 @ApiOperation(value = "get value by foreign currency", response = Property.class)
@RequestMapping(method = RequestMethod.GET, value = "/properties/{id}")
@ResponseBody
public ResponseEntity<BigDecimal> getValueByForeignCurrency(@PathVariable Long id,
                                                @RequestParam("currency") String currency, Locale locale) {
    if (!ForeignCurrency.isLegalCurrency(currency)) {
        throw new IllegalArgumentException("Currency: " + currency + " is not legal");
    }

    BigDecimal foreignValue = propertyService.getPropertyValueInForeignCurrency(id, currency, locale);

    return ResponseEntity.ok().cacheControl(CacheControl.maxAge(1, TimeUnit.HOURS))
            .body(foreignValue);
}

有人知道我做错了什么吗？

SpringSecurity默认设置为无缓存模式。

您可以在HttpServletResponse对象中设置缓存设置。

@RequestMapping(value = "/", method = RequestMethod.GET) 
public String welcome(HttpServletResponse response) { 
    response.setHeader("Cache-Control", "no-transform, public, max-age=3600"); 
    return "welcome"; 
}
