Spring MVC @AutoWired响应不起作用

问题描述

我有：

@Controller
@RequestMapping(value="admin/*", method=RequestMethod.GET)
public class AdminController {

    @Autowired
    private HttpServletRequest request;

    @Autowired
    private HttpServletResponse response;

    @RequestMapping
    public ResponseEntity<String> test0() {
        System.out.println("ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ");
        return null;
    }


}

和标签：

<mvc:annotation-driven />

它我觉得应该足够了，但@Autowired有问题：

It should be enough I feel, but there is a problem with @Autowired:

找不到类型为[javax.servlet.http.HttpServletResponse]的匹配bean ：预计至少有1个符合条件的bean ...

我看过几个解决方案提到设置bean等等，但我相信它已经有了做一些更好的方法。注释扫描应该解决这个问题。如果我必须在xml中为不同时间的几个不同注释设置bean，那就太糟糕了。我只想在我使用它们时注释工作！

I have seen a couple of solutions mention setting up beans and such, but I am sure there has to be some better way. The annotation-scan should take care of this. It would suck if I have to set up beans in xml for several different annotations at different times. I just want the annotations to work when I use them!

我看到：

谢谢！

推荐答案

自动装配没有'为响应工作，只有请求。有解决方法，但它们有点hacky和lame。我遇到了同样的问题，这是我的原始问题以及解决方法的链接：

Autowiring doesn't work for the response, only the request. There are workarounds, but they're kind of hacky and lame. I ran into the same issue, here's my original question with a link to the workaround: @Autowired HttpServletResponse
