找不到org.springframework.util.ClassUtils.getMethod并且无法初始化DefaultConversionService

运行我的应用程序后，它会在控制台中显示以下错误。 我研究了这个问题，但答案没有用。

虽然它显示了应用程序的第一页，但是当我输入地址时，它会显示以下错误而不是所选页面的内容。

我想这个问题与我的依赖关系有关，但不知道如何解决它。

的pom.xml

  4.0.0 Spring2 Spring2 0.0.1-SNAPSHOT Spring2 http://maven.apache.org   javax.servlet javax.servlet-api 3.1.0   org.springframework spring-context 4.1.5.RELEASE   org.springframework spring-webmvc 4.1.5.RELEASE   org.springframework spring-web 4.1.5.RELEASE   commons-logging commons-logging 1.2   org.springframework spring 2.5.6   org.springframework spring-core 4.1.5.RELEASE   junit junit 4.0 test    Spring   

pom.xml2

我更新了我的maven依赖关系，但无济于事

    javax.servlet javax.servlet-api 3.0.1   org.springframework spring-context 4.1.4.RELEASE   org.springframework spring-web 4.1.4.RELEASE   org.springframework spring-context 4.1.4.RELEASE   org.springframework spring-webmvc 4.1.4.RELEASE   org.springframework spring-web 4.1.4.RELEASE   commons-logging commons-logging 1.2   org.springframework spring 2.5.6   org.springframework spring-core 4.1.4.RELEASE   commons-codec commons-codec 1.10   junit junit 4.0 test

正如我所料，问题在于依赖关系。 我可以通过更新我的pom.xml和清理项目来解决问题。

的pom.xml

  4.0.0 Spring2 Spring2 0.0.1-SNAPSHOT Spring2 http://maven.apache.org  4.1.5.RELEASE    org.springframework spring-core ${spring.version}   org.springframework spring-web ${spring.version}   org.springframework spring-webmvc ${spring.version}   junit junit 4.0 test
