Spring 웹 개발 기본 구조 연결 설정법(Eclipse)

스프링(Spring) 기본 설정 순서 

 

1. web.xml
2. *-context.xml  //application-context.xml, servlet-context.xml, root-context.xml 
3. globals.properties  //Java Resources/src/main/resources 내부에 globals.properties.를 생성

 

web.xml 기본 설정

properties 설정 (microsoft sqlServer 설정법)

jdbc.driverClassName = com.microsoft.sqlserver.jdbc.SQLServerDriver <!-- microsoft sql 설정법 -->
jdbc.url = jdbc:sqlserver://[DB IP주소];DatabaseName=[DB 이름];encrypt=true;trustServerCertificate=true;
jdbc.username = [DB 계정아이디]
jdbc.password = [DB 계정비밀번호]

 

mySQL 설정법 

jdbc.driverClassName = com.mysql.cj.jdbc.Driver
jdbc.url = jdbc:mysql://[DB IP주소];DatabaseName=[DB 이름];encrypt=true;trustServerCertificate=true;
jdbc.username = [DB 계정아이디]
jdbc.password = [DB 계정비밀번호]
