spring boot redirect to html page
<p>This is a controller of springboot, I want to write a function to redirect to an html page, but it always responded with 404, and here is the code and properties.
'</p>

<pre><code>@Component

@Controller

@RequestMapping("/Weixin")

public class KindlePocketController {

private static final long serialVersionUID = 1L;

@Autowired
private TextBookInfoSearchService searchService;

@RequestMapping("/homepage")
public String toIndex() {
    System.out.println("redirecting to homepage...");
    return "index";
}
}
</code></pre>

<p>'
application.properties
'</p>

<pre><code>spring.view.prefix=/WEB-INF/views/

spring.view.suffix=.html
</code></pre>

<p>'</p>

<p>the program can get into the function and output is ok. And index.html is in this path:/WEB-INF/views/index.html. Is there any else configurations ?
Thanks a lot</p>
