Question

我不知道出了什么问题。

我会将这些消息来源和建议附在我身上，为什么会发生错误..

的pom.xml

  <!-- https://mvnrepository.com/artifact/org.springframework/spring-webmvc -->
<dependency>
     <groupId>org.springframework</groupId>
     <artifactId>spring-webmvc</artifactId>
     <version>4.3.8.RELEASE</version>
  </dependency>

这是错误代码

org.springframework.beans.factory.BeanInitializationException: Error loading DispatcherServlet's default strategy class [org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerExceptionResolver] for interface [org.springframework.web.servlet.HandlerExceptionResolver]: problem with class file or dependent class; nested exception is java.lang.NoClassDefFoundError: org/springframework/core/annotation/SynthesizingMethodParameter
    at org.springframework.web.servlet.DispatcherServlet.getDefaultStrategies(DispatcherServlet.java:830)
    at org.springframework.web.servlet.DispatcherServlet.initHandlerExceptionResolvers(DispatcherServlet.java:669)
    at org.springframework.web.servlet.DispatcherServlet.initStrategies(DispatcherServlet.java:489)

    at org.springframework.web.servlet.FrameworkServlet$ContextRefreshListener.onApplicationEvent(FrameworkServlet.java:1121)
    at

我不知道为什么会收到错误。

请让我知道如何解决问题。

Answer 1

您需要在pom.xml中为spring-core添加依赖项。以下片段应该可以解决您的问题：

<!-- https://mvnrepository.com/artifact/org.springframework/spring-core -->
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-core</artifactId>
    <version>4.3.8.RELEASE</version>
</dependency>

Answer 2

有一个NoClassDefFoundError我想你没有包含spring-core。以下是应该添加到pom.xml的缺失依赖项：

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-core</artifactId>
    <version>4.3.8.RELEASE</version>
</dependency>

请告诉我Spring MVC错误
