Your class should extend WebMvcConfigurerAdapter class. please have a look at below example

<pre><code>@Configuration
@ComponentScan(basePackages="com")
@EnableWebMvc
public class MvcConfiguration extends WebMvcConfigurerAdapter{

 @Bean
 public ViewResolver getViewResolver(){
 InternalResourceViewResolver resolver = new InternalResourceViewResolver();
 resolver.setPrefix("/WEB-INF/views/");
 resolver.setSuffix(".jsp");
 return resolver;
 }
}
</code></pre>

blocks|key|203192|text|上面的问题是，在定义bean+getViewResolver之前调用了DispatcherServlet.initViewResolvers+get，并且它找不到bean，所以它从来没有添加视图解析器。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|203193|如果您将bean定义移动到xml定义中，它将被拾取。由于某些原因，如果MvcConfiguration中没有定义DispatcherServlet，那么您定义的XML类不会触发ViewResolvers刷新。|203194|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

The problem with the above is that the DispatcherServlet.initViewResolvers get's called before the bean getViewResolver is defined and it cannot find the bean so it never adds the view resolver.

If you move the bean definition into an xml definition, it get's picked up. For some reason the MvcConfiguration class you have defined does not trigger a DispatcherServlet refresh if there are no ViewResolvers defined in the XML.

blocks|key|2832081|text|我用Spring+4.3.4测试了你的场景，它工作正常。我建议仔细检查您扫描的包，以及是否正确提供了AppConfig。我附加了从你的AppConfig开始的所有文件。然而，扩展WebMvcConfigurerAdapter是一件好事。所附的源代码并不理想，它过于简单化，只是为了重现您所报告的问题。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2832082|从AppConfig开始：|2832083|package+com;

I tested your scenario with Spring 4.3.4 and it is working ok.
I would suggest double checking packages you scan and that AppConfig is properly provided.
I am attaching all files starting from your AppConfig. Yet it is good to extend WebMvcConfigurerAdapter. The source code attached is not ideal, it s simplistic and only to try to reproduce the problem you have reported.

Starting from AppConfig:

<pre><code>package com;

import org.springframework.context.annotation.*;
import org.springframework.web.servlet.view.*;

@Configuration
@ComponentScan("com")
public class AppConfig {
 @Bean
 public UrlBasedViewResolver getViewResovler() {
 UrlBasedViewResolver urlBasedViewResolver = new UrlBasedViewResolver();
 urlBasedViewResolver.setViewClass(JstlView.class);
 urlBasedViewResolver.setPrefix("/WEB-INF/jsp/");
 urlBasedViewResolver.setSuffix(".jsp");
 return urlBasedViewResolver;
 }

}
</code></pre>

Then: 

<pre><code>package com;

import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;

 public class WebInit extends AbstractAnnotationConfigDispatcherServletInitializer {

 @Override
 protected Class&lt;?&gt;[] getRootConfigClasses() {
 return new Class&lt;?&gt;[] { };
 }

 @Override
 protected Class&lt;?&gt;[] getServletConfigClasses() {
 return new Class&lt;?&gt;[] { AppConfig.class };
 }

 @Override
 protected String[] getServletMappings() {
 return new String[] { "/" };
 }
 }
</code></pre>

Finally:

<pre><code>package com;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class MainController {

 @RequestMapping("/")
 public ModelAndView asdf() {
 return new ModelAndView("ABC");
 }
}
</code></pre>

Is it possible in <a href="http://en.wikipedia.org/wiki/Spring_Framework" rel="noreferrer">Spring</a> 3.1.1 to configure a view resolver using Java annotations?
I am done with all configurations using Java annotations, but I am stuck at view resolver.
<h3>Code</h3>
<pre><code>package com;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.jdbc.datasource.DriverManagerDataSource;
import javax.sql.DataSource;
import org.springframework.jdbc.datasource.DataSourceTransactionManager;
import com.*;
import org.springframework.web.servlet.view.InternalResourceViewResolver;
import org.springframework.web.servlet.view.UrlBasedViewResolver;
import org.springframework.web.servlet.view.JstlView;

@Configuration
@ComponentScan(&quot;com&quot;)
public class AppConfig
{
 {
 //Other bean declarations
 }

 @Bean
 public UrlBasedViewResolver urlBasedViewResolver()
 {
 UrlBasedViewResolver res = new InternalResourceViewResolver();
 res.setViewClass(JstlView.class);
 res.setPrefix(&quot;/WEB-INF/&quot;);
 res.setSuffix(&quot;.jsp&quot;);

 return res;
 }
}
</code></pre>
I used this code and ran the application, but it's not returning the appropriate view. However, if I configure a viewresolver in the <code>app-servlet.xml</code> file, it works fine.

ViewResolver using Java annotation

Java

在Java3.1.1中是否可以使用注解来配置视图解析器？我已经完成了使用Java的所有配置，但我仍然只能使用视图解析器。代码package com;import org.springframework.context.annotation.Bean;import org.springframework.context....
