이런 에러일 경우, 첫번째로 에러가 난 xml 파일에 xsi:scehmaLocation에서 xsd 버전과 스프링 버전이 맞는지 체크해야한다.

내 경우는 xsd 버전은 3.2 였는데, 

<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
                        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsd
                        http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.2.xsd">

스프링 버전이 3.1.1 버전이라 pom.xml에서 스프링 버전을 3.2 버전대로 업그레이드 시켰다.(빨간색부분 참조)

        <java-version>1.7</java-version>

    </properties>

(* 여기서 바로 해결이 안됐지만, 다른 에러이므로 다른 포스팅에서 올림)

그래도 해결이 안된다?

둘째로 오타가 있는데 체크해야한다.

구글링에서 어떤 사람은 xsi:schemaLocation을 xsi:schemlocation 즉, 대문자 L을 써야하는데 소문자 l을 써서

찾지 못했다고 한다.
