I dont think your dispatcher is configured correctly in your web.xml. You do not have any <init-param>tags. See docs
我不认为您的调度程序在您的 web.xml 中配置正确。您没有任何<init-param>标签。查看文档

Try editing to:
尝试编辑：
<servlet>
<servlet-name>product</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/product-servlet.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>

<servlet>

<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/product-servlet.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
EDIT for additional infoAlso, I believe you will need to add some mapping to your @RequestMapping annotation, see link:
编辑其他信息此外，我相信您需要在@RequestMapping 注释中添加一些映射，请参阅链接：

First clean your project and build again. Check whether you are getting this error.
Then Check with this: nested exception is java.lang.NoSuchMethodError:
org.springframework.core.annotation.AnnotatedElementUtils.hasAnnotation
I think you have missed some repositories in pom.xml or multiple jars of different versions in your pom.xml. Sometimes your spring jars not match mutually with each other.
我认为您错过了 pom.xml 中的一些存储库或 pom.xml 中不同版本的多个 jar。有时您的弹簧罐彼此不匹配。
Add this:
添加这个：
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-framework-bom</artifactId>
<version>4.3.3.RELEASE</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
Remove 4.3.3.RELEASE from all spring dependencies.
从所有 spring 依赖项中删除 4.3.3.RELEASE。
Refer: http://docs.spring.io/spring/docs/current/spring-framework-reference/html/overview.html(Read: Maven "Bill Of Materials" Dependency)
参考：http: //docs.spring.io/spring/docs/current/spring-framework-reference/html/overview.html（阅读：Maven“材料清单”依赖）

Probably you have forgot to import your product-serlet to configuration class
可能您忘记将 product-serlet 导入到配置类
you could move your product-servlet.xml to 'resources' so that it is available in classpath
您可以将您的 product-servlet.xml 移动到“资源”，以便它在类路径中可用
so your servlet mapping looks like this
所以你的servlet映射看起来像这样
<servlet>
<servlet-name>product</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:/product-servlet.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>product</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
in your config
在你的配置中
@Configuration
@EnableTransactionManagement
@ComponentScan("com.kopylov.spring")
@PropertySource("classpath:/com/kopylov/spring/resources/app.properties")
@EnableJpaRepositories("com.kopylov.spring.repository")
@ImportResource("classpath:/product-servlet.xml")
public class DataConfig {
//..
}
BTW, better not to mix match xml and java configuration. As java config has become norm, you could use WebMvcConfigurerAdapter
顺便说一句，最好不要混合匹配 xml 和 java 配置。由于 java 配置已成为常态，您可以使用WebMvcConfigurerAdapter

First check if all of the build path errors are resolved or not. In most of this kind of cases spring initializer throws this error if build path errors are not resolved.
首先检查所有构建路径错误是否已解决。在大多数这种情况下，如果未解决构建路径错误，spring 初始化程序会抛出此错误。

Perfect solution worked for me :
完美的解决方案对我有用：
Add commons-configuration-1.6.jar to the lib directory
将 commons-configuration-1.6.jar 添加到 lib 目录
