[spring] 보안 Security - 1
[spring] 보안 Security - 1
1. 보안 관련 라이브러리 추가
방법 1. https://docs.spring.io/spring-security/site/docs/5.0.6.RELEASE/reference/htmlsingle/ 에서 다운받거나 dependency 추가
방법 2. 이클립스 기준 pom.xml -> 하단 Dependencies탭 클릭 -> Add.. 클릭 -> Enter groupId, artifactId or sha1 prefix ... 에 security 검색
-> org.springframework.security(spring-security-acl) 선택
(1) security-context.xml 생성 ( src/main/webapp/WEB-INF/spring/appServlet/security-context.xml )
[내용]
<?xml version="1.0" encoding="UTF-8"?>
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:security="http://www.springframework.org/schema/security"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/security
http://www.springframework.org/schema/security/spring-security-3.2.xsd">
</beans>
* 해당경로에 오른쪽 클릭해서 xml생성을해서 next를 누르면 사용할 bean을 선택한다
security를 체크하고 맨위의 최신버전을 체크해서 사용하자.
(2) web.xml에 security-context.xml를 추가하자. ( src/main/webapp/WEB-INF/web.xml )
[web.xml]
....
<!-- The definition of the Root Spring Container shared by all Servlets and Filters -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/spring/root-context.xml
/WEB-INF/spring/appServlet/security-context.xml
</param-value>
</context-param>
....
2. In-Memory 인증
(1) security-context.xml 생성 후 내용추가 ( src/main/webapp/WEB-INF/spring/appServlet/security-context.xml )

(2) 필터추가 ( src/main/webapp/WEB-INF/web.xml )
[web.xml]
....
<filter>
<filter-name>springSecurityFilterChain</filter-name>
<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>
<filter-mapping>
<filter-name>springSecurityFilterChain</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
