spring-web和spring-webmvc 版本冲突jar包冲突

spring-mvc项目启动成功，但是通过http访问接口时，发生异常。具体报错信息如下：

报错原因：Caused by: java.lang.NoSuchMethodError: org.springframework.http.HttpMethod.matches(Ljava/lang/String;)Z

排查问题过程中发现，spring-web这个包版本是4.2.3，但spring-webmvc这个包版本是4.2.4，该包需要用到matches()方法。
在4.2.4版本spring-web包中，HttpMethod这个类如下：

package org.springframework.http;

import java.util.HashMap;
import java.util.Map;

public enum HttpMethod
{
  GET,  HEAD,  POST,  PUT,  PATCH,  DELETE,  OPTIONS,  TRACE;
  
  private static final Map mappings;
  
  static
  {
    mappings = new HashMap(8);
    for (HttpMethod httpMethod : values()) {
      mappings.put(httpMethod.name(), httpMethod);
    }
  }
  
  public static HttpMethod resolve(String method)
  {
    return method != null ? (HttpMethod)mappings.get(method) : null;
  }
  
  public boolean matches(String method)
  {
    return name().equals(method);
  }
  
  private HttpMethod() {}
}

而spring-web 4.2.3中该类HttpMethod没有matches方法.所以才报错的。

解决方法：把spring-webmvc版本号降为4.2.3即可

最后，附上详细报错日志：
