Answer 1

XML 파일 만 DTD를 사용하여, 기존 spring2.0 형식입니다. Spring3 이후 xml 스키마를 사용하여 새로운 형식을 사용해야한다. 그러나 왜 당신이 질문에 제공 한 링크의 페이지에서 형식을 유지하지 않았습니까? 코멘트 당

편집 :

2.5 버전은 더 이상 유지 제네릭을 사용하지 않는, 지금은 오히려 구식입니다. Spring framework site에서 일반적으로 사용 가능한 버전은 3.2, 4.0 및 4.1입니다. 그러나 2.5.6을 사용하는 데는 충분한 이유가있을 수 있습니다.

해당 버전의 경우, 당신은 여전히 ​​DTD를 사용할 수 있지만, 크리스 톰슨 상태로, 적어도이 있어야합니다 <?xml version="1.0" encoding="UTF-8"?>

그래서 당신은 할 수 있습니다 :

<?xml version="1.0" encoding="UTF-8"?> 
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.0//EN" 
    "http://www.springframework.org/dtd/spring-beans-2.0.dtd"> 

<beans> 
... 
</beans> 

또는 n XML 스키마를 -style

<?xml version="1.0" encoding="UTF-8"?> 
<beans xmlns="http://www.springframework.org/schema/beans" 
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
     xsi:schemaLocation=" 
http://www.springframework.org/schema/beans 
    http://www.springframework.org/schema/beans/spring-beans-2.5.xsd"> 
...
