spring security基礎配置

今天開始看Spring security，從最簡單的hello world開始，但是一上來就被XML配置文件卡住了，折騰三個小時，終於解決。

最上來的時候是提示無法找到XML定義，這就鬱悶了，定義明明就包含在jar包中，jar包也配在構建路徑中了，然後各種折騰，把包重新導入了一遍不行，換到了WEB-INFI/lib下還不行，最後把myeclipse重啓一下，就莫名其妙好了，實在讓人鬱悶。

記錄一下一個最簡單的基礎配置：

使用myeclipse自帶的3.0的包

application-security.xml

<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-3.0.xsd
           http://www.springframework.org/schema/security
           http://www.springframework.org/schema/security/spring-security-3.0.xsd">

	<http auto-config='true'>
		<intercept-url pattern="/**" access="ROLE_USER" />
	</http>

	<authentication-manager>
		<authentication-provider>
			<user-service>
				<user name="admin" password="admin" authorities="ROLE_USER, ROLE_ADMIN" />
				<user name="user" password="user" authorities="ROLE_USER" />
			</user-service>
		</authentication-provider>
	</authentication-manager>

</beans:beans>

web.xml，需要將Spring security的攔截器加上

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" 
	xmlns="http://java.sun.com/xml/ns/javaee" 
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
	http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
  <display-name></display-name>
