톰캣 설치 에러

로컬 컴퓨터의 apache tomcat 7.0 tomcat7을 시작하지 못했습니다
Apache Tomcat 8.0 Tomcat8 서비스가 서비스 특정 오류
잘못된 기능입니다. 때문에 종료되었습니다.
msvcr71을 해도 안됨 아마도 32비트 톰캣을 64비트로 변경해서 된듯

1. 해당 jar파일이 있는 곳으로 도스 프롬프트를 이동

2.  jar -uvf "기존의 Jar명" 교체될 클래스

jar -uvf test-V2.1.jar /bin/com/itcomm/itsfw/core/ObjectCache.class

3. 이때 패키지내의 교체될 클래스의 위치를 지정해주고  교체될 클래스 파일은 해당 경로에 존재해야 한다.

jar -uvf test.jar
jar -uvf test.jar .\core\database\ObjectCache.class
jar -uvf test.jar ./core/ObjectCache.class
jar -uvf test.jar ./database/ObjectCache.class

tomcat manager

The page you tried to access (/manager/loginPw) does not exist.
The Manager application has been re-structured for Tomcat 7 onwards and some of URLs have changed. All URLs used to access the Manager application should now start with one of the following options:
/manager/html for the HTML GUI
/manager/text for the text interface
/manager/jmxproxy for the JMX proxy
/manager/status for the status pages
Note that the URL for the text interface has changed from "/manager" to "/manager/text".
You probably need to adjust the URL you are using to access the Manager application. However, there is always a chance you have found a bug in the Manager application. If you are sure you have found a bug, and that the bug has not already been reported, please report it to the Apache Tomcat team.

spring message convert

메시지 컨버터를 별도로 선언하지 않으면 Spring 에서 등록하는 디폴트 메시지 컨버터는 다음과 같다.

ByteArrayHttpMessageConverter
, StringHttpMessageConverter
, FormHttpMessageConverter
, SourceHttpMessageConverter

Current request is not of type [org.springframework.web.multipart.MultipartHttpServletRequest]

// 해결
MultipartHttpServletRequest => HttpServletRequest로 변경해서 처리

((HeaderWriterFilter.HeaderWriterRequest) ((HttpServlet3RequestFactory.Servlet3SecurityContextHolderAwareRequestWrapper) document).request).getHeaders("Content-Length")

// 일반적인 방법
// 1. spring 설정에서 multipartResolver가 bean으로 주입이 되었는지,
// ex)<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"/>
//
// 2. form에서 enctype이 multipart/form-data 으로 되었는지,
// ex)<form id="fileupload" method="post" enctype="multipart/form-data">
//
// 3. Controller에서 Request 를 MultipartHttpServletRequest 로 받고 있는지 확인합니다.
// 올려주신 내용만으로는 해당오류의 원인을 파악하기 힘드나, 보통 form 태그에 enctype="multipart/form-data" 지정되지 않은 경우이거나, form tag가 여러 개 있는지, post로 호출하는 부분들을 재 점검해보시기 바랍니다.
// 아니면 함수의 파라미터로 MultipartHttpServetRequest를 넣지 않고 HttpServletRequest 객체로 받아 함수 안에서 캐스팅을 하는 형태로 처리해 보시기 바랍니다.

autowired 에러 관련

양쪽 @Component컴포넌트에서 서로에 @Autowired를 거는 경우 오류 발생가능 주의 (빌드에서는 문제가 없을 수 도 있음. 개발자들에게 주의주기!!) 또는 lazy를 거는형태로 사용

 Application run failed
org.springframework.beans.factory.BeanCurrentlyInCreationException: Error creating bean with name 'returnBsl':
 Bean with name 'returnBsl' has been injected into other beans [orderBsl] in its raw version as part of a circular reference,
 but has eventually been wrapped. This means that said other beans do not use the final version of the bean.
 This is often the result of over-eager type matching - consider using 'getBeanNamesOfType' with the 'allowEagerInit' flag turned off, for example

substring

public static String splitLength(String text, int length){
	int maxLength = length;
	int textLen = text.length();
	String resultText = "";
	if(textLen > length) {
		resultText = text.substring(0, maxLength);
	} else {
		resultText = text;
	}
	return resultText;
}

public static String relaxSubString(String src, int beginIndex, int endIndex) {
	if(DataUtils.isEmpty(src)) {
		return src;
	}
	if(src.length() < beginIndex) {
		return "";
	}
	if(src.length() < endIndex) {
		return src.substring(beginIndex, src.length());
	}
	return src.substring(beginIndex, endIndex);
}
