}|4402409|使用@ResponseBody会将return+"login";作为String对象返回。您返回的任何对象都将作为payload附加到HTTP中。|4402410|这就是为什么在响应中只得到login的原因。|4402411|entityMap^0|5|F|0|0|0|0|2|D|H|F|1L|7|0|D|5|0^^$0|@$1|2|3|4|5|6|7|U|8|@$9|V|A|W|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|X|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|Y|8|@]|D|@]|E|$]]|$1|M|3|N|5|H|7|Z|8|@]|D|@]|E|$I|J]]|$1|O|3|P|5|6|7|10|8|@$9|11|A|12|B|C]|$9|13|A|14|B|C]|$9|15|A|16|B|C]]|D|@]|E|$]]|$1|Q|3|R|5|6|7|17|8|@$9|18|A|19|B|C]]|D|@]|E|$]]|$1|S|3|-4|5|6|7|1A|8|@]|D|@]|E|$]]]|T|$]]

When using <code>@RestController</code> like this:

<pre><code>@RestController
public class HomeController {

 @RequestMapping("/")
 public String welcome() {
 return "login";
 }
}
</code></pre>

This is the same as you do like this in a normal controller:

<pre><code>@Controller
public class HomeController {

 @RequestMapping("/")
 @ResponseBody
 public String welcome() {
 return "login";
 }
}
</code></pre>

Using <code>@ResponseBody</code> returns <code>return "login";</code> as a String object. Any object you return will be attached as <code>payload</code> in the HTTP body as JSON.

This is why you are getting just <code>login</code> in the response.

The answer from Kukkuz did not work for me until I added in this dependency into the pom file:

<pre><code>&lt;!-- Spring boot Thymeleaf --&gt;
&lt;dependency&gt;
 &lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;

From the guide <a href="https://spring.io/guides/gs/serving-web-content/" rel="nofollow noreferrer">here</a>.

As well as updating the registry resources as outlined <a href="https://stackoverflow.com/a/17013442/2480714/">here</a>. 

It then started working just fine. If anyone in the future runs into the same issue and following the first answer does not solve your problem, follow these 2 other steps after utilizing the code in @Kukkuz's answer and see if that makes a difference.

blocks|key|4402610|text|我知道这很古老，但也许它能帮助某些人。要在RestController中执行此操作，请返回一个实际的HTML代码字符串，然后浏览器就会知道要显示什么。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4402611|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I know this is old but maybe it helps someone. To do this in a RestController, return a String that is the actual HTML code, then the browser will know what to display.

blocks|key|4402383|text|因为只返回名称return+"login";，所以只获得名称。它是@RestController，并且该控制器返回数据而不是视图；因此，您只能获得从method返回的内容。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|4402384|如果你想用这个名字显示视图，你需要使用Spring+MVC，see+this+example。|4402385|entityMap|0|LINK|mutability|MUTABLE|url|https://spring.io/guides/gs/serving-web-content/^0|7|F|X|F|0|U|G|0|0^^$0|@$1|2|3|4|5|6|7|P|8|@$9|Q|A|R|B|C]|$9|S|A|T|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|U|8|@]|D|@$9|V|A|W|1|X]]|E|$]]|$1|H|3|-4|5|6|7|Y|8|@]|D|@]|E|$]]]|I|$J|$5|K|L|M|E|$N|O]]]]

You get only the name because you return only the name <code>return "login";</code>. It's <code>@RestController</code> and this controller returns data rather than a view; because of this, you get only content that you return from method.

If you want to show view with this name you need to use Spring MVC, <a href="https://spring.io/guides/gs/serving-web-content/" rel="nofollow noreferrer">see this example</a>.

You can specify GET or POST method inside RequestMapping like this:-
