안녕하세요.

spring DB 로그 추가에 대해 써보겠습니다.

DB를 불러오고난 뒤 부터 시작하겠습니다.

이전글을 참조해주세요. (spring MVC DB 연결하기)

             <property name="sqlPrefix" value="SQL : "/> 
         </bean>

 </bean>

수정

기존에 있는 dataSource를 dataSourceSpied로 변경

 

다시 호출해보면 결과가 이렇게 나옵니다.

 

 

 

 

감사합니다.

안녕하세요.

spring mvc db 연결에 대해 설명하겠습니다.

해당 설명은 eclispe의 spring Project생성을 기반으로 하였음을 알려드립니다.

후에 기본 패키지 입력 후 finish

ex) com.java.spring

 

프로젝트 생성 후 선택되어있는 부분을 클릭하여 F2눌르고 controller, mapper, service패키지를 추가입력하여 하단 생성

결과 1. HomeServiceImpl.java 에서 결과 로그

 

결과 2. home.jsp에서 결과

일단 DB의 결과를 표시하는 것만 했습니다.

jstl이나 dbㄹ그 추가등은 뒷글에 나올예정입니다.

 

감사합니다.
