스프링 암호화 기능

Spring 암호화 해보기

 

1. pom.xml 작성

---

<!--스프링시큐리티 web 라이브러리-->
		<dependency>
		    <groupId>org.springframework.security</groupId>
		    <artifactId>spring-security-web</artifactId>
		    <version>4.1.0.RELEASE</version>
		  </dependency>
		  <!--스프링시큐리티 core 라이브러리-->
		  <dependency>
		    <groupId>org.springframework.security</groupId>
		    <artifactId>spring-security-core</artifactId>
		    <version>4.1.0.RELEASE</version>
		  </dependency>
		  <!--스프링시큐리티 config 라이브러리-->
		  <dependency>
		    <groupId>org.springframework.security</groupId>
		    <artifactId>spring-security-config</artifactId>
		    <version>4.1.0.RELEASE</version>
		</dependency>

 

2. spring-security.xml 작성

---

src/main/resources/config 경로에 spring-security.xml 파일을 만들고 코드를 추가한다.

<?xml version="1.0" encoding="UTF-8"?>
<beans:beans xmlns="http://www.springframework.org/schema/security"
    xmlns:beans="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    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.xsd">

    <beans:bean id="bcryptPasswordEncoder" class="org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder" />  

</beans:beans>

 

3. web.xml 작성

---

<!-- The definition of the Root Spring Container shared by all Servlets and Filters -->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>
			classpath:config/root-context.xml
			classpath:config/spring-security.xml
		</param-value>
		<!-- <param-value>/WEB-INF/spring/root-context.xml</param-value> -->
	</context-param>

추가하여 준다.

 

4. Controller 작성

---

상단에 선언

@Autowired
	private BCryptPasswordEncoder pwdEncoder;

	String aa = "hello";
		String aaPwd = pwdEncoder.encode(aa);
		String bb = "hello";
		String cc="ldy";
		
		if(pwdEncoder.matches(bb, aaPwd)) {
			System.out.println("hello");
		}
		if(pwdEncoder.matches(cc, aaPwd)) {
			System.out.println("ldy");
		}else {
			System.out.println("not matches");
		}
