[Spring Framework] 전자정부 프레임워크 POST 발송시 한글깨짐 해결

전자정부 프레임워크로 개발을 진행하다

특정 상황에서 한글 깨짐이 발생했다.

Web.xml에 UTF-8필터가 없던 상태 찾아보니 전자정부 프레임워크는 서블릿 3.0 이상부터

Web.xml대신 EgovWebApplicationInitalizer.java로 대신하게 되어있다.

public class EgovWebApplicationInitializer implements WebApplicationInitializer {
 
	private static final Logger LOGGER = LoggerFactory.getLogger(EgovWebApplicationInitializer.class);
	@Override
	public void onStartup(ServletContext servletContext) throws ServletException {

		//characterEncoding.addMappingForUrlPatterns(EnumSet.of(DispatcherType.REQUEST), true, "*.do");

확인해보니 characterEncoding.addMappingForUrlPatterns(null, false, "*");

라는 구문이 characterEncoding.addMappingForUrlPatterns(null, false, "*.do");

로 기본 설정되어있다. 현재 진행하는 프로젝트는 *.do로 끝나지 않기 때문에 

UTF-8 필터가 제대로 설정되지 않았던 것 *로 변경하여 접속되는 모든 URL에 UTF-8을 적용시켰다.
