今天領導要了我們前端組從十月到年末的開發計劃,發現年底的項目終於迴歸到了javascript做前端了,到時好好練練手。另外,發現以後可能會經常做權限管理,所以現在正好有點時間打算把SpringSecurity資料認真整理下,今天是入門級的,希望以後會越來越來越深入。
java項目首先要提的就是jar包了,Springsecurity的jar下載地址:http://static.springsource.org/spring-security/site/downloads.html。不過我的項目裏的jar包比較舊點了,是從以前項目抽取出來的,我的工程結構圖如下:
第一個實例:
第一個例子是最基本,最簡單的,我第一次接觸springsecurity時候覺得這個技術真驚豔,不過現在感覺也就那麼回事了。
我首先編寫的是web.xml:
<?xml version=
"1.0"
encoding=
"UTF-8"
?>
<web-app xmlns:xsi=
"http://www.w3.org/2001/XMLSchema-instance"
xmlns=
"http://java.sun.com/xml/ns/javaee"
xmlns:web=
"http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
xsi:schemaLocation=
"http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
id=
"WebApp_ID"
version=
"2.5"
>
<display-name>SpringSecurityPrj</display-name>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
classpath:applicationContext*.xml
</param-value>
</context-param>
<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>
<listener>
<listener-
class
>org.springframework.web.context.ContextLoaderListener</listener-
class
>
</listener>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>
|
接下來編寫的是applicationContext-security.xml文件:
<?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"
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.w3.org/2001/XMLSchema-instance"
