创建名称为 'org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping' 的 Bean

Question

使用jdk 1.8

1. 弹簧MVC-4.3.3
2. 弹簧芯-4.3.3
3. javax.servlet-api-3.0.1
4. 春季数据jpa:1.10.4
5. hibernate实体管理器：4.2.5.最终
6. hibernate内核：4.2.5.最终
7. Java的简单日志界面：1.6.1

我遇到这样的错误

org.springframework.beans.factory.BeanCreationException：错误使用名称创建bean"org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping"：init方法调用失败；嵌套异常为java.lang.NoSuchMethodError：org.springframework.core.annotation.AnnotatedElementUtils.hasAnnotation

我的问题：
为什么会出现错误以及如何修复？

Answer 1

完美的解决方案适用于我：

将commons-configuration1.6.jar添加到lib目录

Answer 2

可能您忘记了将产品servlet导入配置类

您可以将product-servlet.xml移动到"resources"，以便它在类路径中可用

所以servlet映射看起来像这个

<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>

在您的配置类中

 @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 {
    //..
    }

顺便说一句，最好不要混用xml和java配置。由于java配置已成为常态，您可以使用WebMvcConfigurerAdapter

Answer 3

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

我想你已经错过了pom.xml中的一些存储库或pom.xml的多个不同版本的jar。有时你的spring jar彼此不匹配。

添加此：

<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>

从所有弹簧依赖项中删除4.3.3.RELEASE。

参考：http://docs.spring.io/spring/docs/current/spring-framework-reference/html/overview.html(阅读：Maven"物料清单"依赖项(

<dependencies>
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-web</artifactId>
</dependency>
<dependencies>

Answer 4

我认为您的调度器在web.xml中配置不正确。您没有任何<init-param>标记。参见文档

http://docs.spring.io/spring-flex/docs/1.0.x/reference/html/ch02s02.html

尝试编辑为：

<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>

编辑以获取更多信息此外，我相信您需要在@RequestMapping注释中添加一些映射，请参阅链接：

http://docs.spring.io/spring/docs/current/spring-framework-reference/html/mvc.html#mvc-ann请求映射

Answer 5

首先检查是否解决了所有构建路径错误。在大多数这种情况下，如果未解决构建路径错误，spring初始值设定项会抛出此错误。
