如何更新到org.springframework spring-web.jar的最新版本

Question

我正在通過STS和Maven依賴項來構建“ Hello World” Spring MVC項目。 我有Spring-core，beans和上下文4.3.6-RELEASE.jars。 但是Spriing-web和Spring-webmvc 3.1.1-RELEASE.jar當我啟動Tomcat服務器v7.0時，它給出了錯誤消息：

ERROR: org.springframework.web.servlet.DispatcherServlet - Context initialization failed
org.springframework.beans.factory.BeanDefinitionStoreException: 
Failed to read candidate component class: file [C:\Users\jimme\Documents\Spring\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\SpringMvcDemo-18thFeb\WEB-INF\classes\co\edureka\myapp\HomeController.class]; 
nested exception is java.lang.IncompatibleClassChangeError: class org.springframework.core.type.classreading.ClassMetadataReadingVisitor has interface org.springframework.asm.ClassVisitor as super class

SEVERE: StandardWrapper.Throwable
org.springframework.beans.factory.BeanDefinitionStoreException: Failed to read candidate component class: file [C:\Users\jimme\Documents\Spring\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\SpringMvcDemo-18thFeb\WEB-INF\classes\co\edureka\myapp\HomeController.class]; 
nested exception is java.lang.IncompatibleClassChangeError: class org.springframework.core.type.classreading.ClassMetadataReadingVisitor has interface org.springframework.asm.ClassVisitor as super class

是由於spring-web和webmvc jar的發行版嗎？ 如果我想將spring-web和webmvc更新到4.3.6-RELEASE.jar，我該怎么做？ 有人可以幫幫我嗎？

如果要更新依賴項的版本，則只需將pom.xml更新為所需的版本即可。

但是我建議您進行以下設置，以便您在maven中的所有spring依賴項都與同一版本一致

<project xmlns="http://maven.apache.org/POM/4.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
    http://maven.apache.org/maven-v4_0_0.xsd">
    ...
    ...
<properties>
    <spring.version>4.3.6.RELEASE</spring.version>
    <jstl.version>1.2</jstl.version>
</properties>

<dependencies>

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-core</artifactId>
            <version>${spring.version}</version>
        </dependency>

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context</artifactId>
            <version>${spring.version}</version>
        </dependency>

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-web</artifactId>
            <version>${spring.version}</version>
        </dependency>

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-webmvc</artifactId>
            <version>${spring.version}</version>
        </dependency>

        ...
</dependencies>
</project>

首先右鍵單擊->運行為-> Maven Clean，然后運行為-> Maven安裝

${spring.version}將確保所有版本都相同，並且將更新（升級）到較新版本也很容易。

希望能有所幫助！
