spring--security

security spring

1.下载spring security的最新版本，工程下载的是3.1

2. 新建工程，结构如下：

其中，涉及到的jar包可以在spring-security包中的例子中获取

3、配置spring-security.xml

Xml代码

<? xml version = "1.0" encoding = "UTF-8" ?>
< beans xmlns = "http://www.springframework.org/schema/beans"
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.xsd">
< security:http auto-config = "true" >
< security:intercept-url pattern = "/**" access = "ROLE_USER" />
</ security:http >
< security:authentication-manager >
< security:authentication-provider >
< security:user-service >
< security:user name = "user" password = "user" authorities = "ROLE_USER" />
</ security:user-service >
</ security:authentication-provider >
</ security:authentication-manager >
</ beans >

4.配置web.xml

Xml代码

<? 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" >
