最近两星期在学习acegi,过程中感谢 JavaEye, SpringSide和在网上提供acegi学习心得的网友们。
为了加深自己的认识,准备写下一些DEMO,希望可以给准备学习acegi的同学一些帮助。
作为安全服务离不开认证和授权这两个主要组成部分。而这篇文章就是针对acegi的认证服务。
《学习Acegi-认证(authentication)》
代码环境基于:
JDK1.5
acegi1.0.3
spring2.0
IDE基于:
Eclipse3.2+MyEclipse5.0.1
面向人员:
熟悉Eclipse+MyEclipse开发但刚开始了解acegi的人员。如果你是高手请指出文章不足之处。
1.建立一个MyEclipse的WebProject,把下列jar文件拷贝到项目的WEB-INF/lib目录:
acegi-security-1.0.3.jar
spring2.0.jar
commons-codec-1.3.jar
费话说一句(占些字数):这是因为代码运行需要这些包的支持。
2.修改WEB-INF下的web.xml文件,内容如下:
- <?xml version="1.0" encoding="UTF-8"?>
- <web-app>
-
- <display-name>acegi Example of liuyxit</display-name>
-
- <!--
- 定义应用的上下文参数,用于ContextLoaderListener
- -->
- <context-param>
- <param-name>contextConfigLocation</param-name>
- <param-value>
- classpath:spring/applicationContext.xml
- </param-value>
- </context-param>
-
- <!--acegi 的filter链代理-->
- <filter>
- <filter-name>Acegi Filter Chain Proxy</filter-name>
- <filter-class>
- org.acegisecurity.util.FilterToBeanProxy
- </filter-class>
- <init-param>
- <param-name>targetClass</param-name>
- <param-value>
- org.acegisecurity.util.FilterChainProxy
- </param-value>
- </init-param>
- </filter>
- <filter-mapping>
- <filter-name>Acegi Filter Chain Proxy</filter-name>
- <url-pattern>/*</url-pattern>
- </filter-mapping>
-
- <!--
- 装载应用软件的Spring上下文
- 要由WebapplicationContextUtils.getWebApplicationnContext(servletContext)得到.
- -->
- <listener>
- <listener-class>
- org.springframework.web.context.ContextLoaderListener
- </listener-class>
- </listener>
- </web-app>
<?xml version="1.0" encoding="UTF-8"?>
<web-app>
<display-name>acegi Example of liuyxit</display-name>
<!--
定义应用的上下文参数,用于ContextLoaderListener
-->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
classpath:spring/applicationContext.xml
</param-value>
</context-param>
<!--acegi 的filter链代理-->
<filter>
<filter-name>Acegi Filter Chain Proxy</filter-name>
<filter-class>
org.acegisecurity.util.FilterToBeanProxy
</filter-class>
<init-param>
<param-name>targetClass</param-name>
<param-value>
org.acegisecurity.util.FilterChainProxy
</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>Acegi Filter Chain Proxy</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!--
装载应用软件的Spring上下文
要由WebapplicationContextUtils.getWebApplicationnContext(servletContext)得到.
-->
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
</web-app>
其中FilterChainProxy实现了filter接口,它主要是实例化FilterChainProxy,并把所有动作交由FilterChainProxy处理。这样简化了web.xml的配置,并且充分利用了Spring IOC管理Bean的优势。
3.在src目录右键新建一个resource folder,在下面再建立acegi和spring目录
在spring目录中创建applicationContext.xml文件,内容:
- <?xml version="1.0" encoding="UTF-8"?>
- <beans xmlns="http://www.springframework.org/schema/beans"
- xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

[list=A]其中filterChainProxy就是由web.xml声明的filter(FilterToBeanProxy)的targetClass。它主要是装载filterInvocationDefinitionSource指定的filter类(例子中为authenticationProcessingFilter,exceptionTranslationFilter),并顺序调用它们的doFilter方法,进行安全服务处理。[/list]
[list=B]而authenticationProcessingFilter是处理一个认证表单,登陆用的表单必须提交用户名和密码这两个参数给这个filter.由用户名和密码构造一个UsernamePasswordAuthenticationToken,将传给AuthenticationManager的authenticate方法进行认证处理。该filter默认处理filterProcessesUrl属性指定的URL,认证失败会转到authenticationFailureUrl,认证成功会转到defaultTargetUrl页面。[/list]
[list=C]AuthenticationManager顾名思义认证管理器,它只有一个接口方法authenticate用于返回认证结果,他的实现类由多个AuthenticationProvider进行投票,决定认证是否通过。[/list]
[list=D]daoAuthenticationProvider是检验用户录入的认证数据是否正确(说白了就是用户名和密码是否正确)[/list]
[list=E]inMemoryDaoImpl是给daoAuthenticationProvider提供系统的用户资料。而资料的来源是从配置中装载到内存的。[/list]
[list=F]当认证不通过时,AuthenticationManager的实现类AbstractAuthenticationManager会抛出AuthenticationException类型的异常。这时排在最后的exceptionTranslationFilter会捕获该异常,并转向authenticationEntryPoint。[/list]
4.在WebRoot下创建index.jsp(其实不要也没关系,主要是为了方便),直接转向用户资料显示页。内容如下:
- <%@ page language="java" pageEncoding="UTF-8"%>
- <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
- <html>
- <head>
- <META HTTP-EQUIV="Refresh" CONTENT="0;URL=userinfo.jsp">
- </head>
-
- <body>
- <p>Loading ...</p>
- </body>
- </html>
<%@ page language="java" pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<html>
<head>
<META HTTP-EQUIV="Refresh" CONTENT="0;URL=userinfo.jsp">
</head>
<body>
<p>Loading ...</p>
</body>
</html>
5.在WebRoot下创建userinfo.jsp,用于显示当前登陆的用户信息。内容如下
- <%@ page language="java" pageEncoding="UTF-8"%>
- <%@ page import="org.acegisecurity.context.SecurityContextHolder"%>
- <%@ page import="org.acegisecurity.userdetails.*"%>
-
- <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

- if (null != obj){
- Object userDetail = SecurityContextHolder.getContext().getAuthentication().getPrincipal();
- String username = "";
- if (userDetail instanceof UserDetails) {
- username = ((UserDetails) userDetail).getUsername();
- } else {
- username = userDetail.toString();
- }
- out.print(username);
- out.print("<br><a href=/"j_acegi_logout/">注销</a>");
- }else{
- out.print("当前没有有效的用户");
- out.print("<br><a href=/"acegilogin.jsp/">登陆</a>");
- }
- %>
- </body>
- </html>

}else{
out.print("当前没有有效的用户");
out.print("<br><a href=/"acegilogin.jsp/">登陆</a>");
}
%>

6.在WebRoot下创建acegilogin.jsp
- <%@ page language="java" pageEncoding="UTF-8"%>
- <%@ page import="org.acegisecurity.ui.AbstractProcessingFilter" %>
- <%@ page import="org.acegisecurity.ui.webapp.AuthenticationProcessingFilter" %>

- <title>Login</title>

- String strError = request.getParameter("login_error");
- if (null != strError){

</html>
7.OK,发布项目,访问http://localhost:8080/acegiexample
这时index.jsp会自动转向userinfo.jsp,由于还没有用户登录,所以没有资料显示。按登陆链接进入登录页,登录成功后会看到显示用户名的页面(当然可以有更多的用户资料,但这仅仅是example),不成功时会在登录页提示信息。我们可以用user1和user2登陆,可以分别测试登录成功和失败的流程。
8.可以看到登录页上有自动登陆功能,而userinfo.jsp页有注销功能。但还是不起作用,好,现在我们马上首手加入这两个功能。看acegi可以方便到什么程度。修改applicationContext.xml如下:
<?xml version="1.0" encoding="UTF-8"?>

另要注意:Acegi默认的自动登陆设定参数名为_acegi_security_remember_me,注销链接为/j_acegi_logout。
马上重启Tomcat测试看看^_^。
9.通常用户资料会放在数据库中,而不会放在配置文件,接着下面我们来再行修改一下。
首先创建要用到的用户表和权限表,并插入初始化数据:
- CREATE TABLE USERS(
- USERNAME VARCHAR( 50 ) NOT NULL PRIMARY KEY,
- PASSWORD VARCHAR( 50 ) NOT NULL,
- ENABLED BIT NOT NULL)
-
- INSERT INTO USERS(username,password,enabled) values( ' liuyxit ' , ' 123 ' , ' 1 ' )
- INSERT INTO USERS(username,password,enabled) values( ' user1 ' , ' user1 ' , ' 1 ' )
- INSERT INTO USERS(username,password,enabled) values( ' user2 ' , ' user2 ' , ' 0 ' )
-
- CREATE TABLE AUTHORITIES(
- USERNAME VARCHAR( 50 ) NOT NULL,
- AUTHORITY VARCHAR( 50 ) NOT NULL,
- CONSTRAINT FK_AUTHORITIES_USERS FOREIGN KEY(USERNAME) REFERENCES USERS(USERNAME)
- );
-
- INSERT INTO AUTHORITIES(USERNAME,AUTHORITY) values( ' liuyxit ' , ' ROLE_SUPERVISOR ' )
- INSERT INTO AUTHORITIES(USERNAME,AUTHORITY) values( ' user1 ' , ' ROLE_USER ' )
- INSERT INTO AUTHORITIES(USERNAME,AUTHORITY) values( ' user2 ' , ' ROLE_USER ' )
CREATE TABLE USERS(
USERNAME VARCHAR( 50 ) NOT NULL PRIMARY KEY,
PASSWORD VARCHAR( 50 ) NOT NULL,
ENABLED BIT NOT NULL)
INSERT INTO USERS(username,password,enabled) values( ' liuyxit ' , ' 123 ' , ' 1 ' )
INSERT INTO USERS(username,password,enabled) values( ' user1 ' , ' user1 ' , ' 1 ' )
INSERT INTO USERS(username,password,enabled) values( ' user2 ' , ' user2 ' , ' 0 ' )
CREATE TABLE AUTHORITIES(
USERNAME VARCHAR( 50 ) NOT NULL,
AUTHORITY VARCHAR( 50 ) NOT NULL,
CONSTRAINT FK_AUTHORITIES_USERS FOREIGN KEY(USERNAME) REFERENCES USERS(USERNAME)
);
INSERT INTO AUTHORITIES(USERNAME,AUTHORITY) values( ' liuyxit ' , ' ROLE_SUPERVISOR ' )
INSERT INTO AUTHORITIES(USERNAME,AUTHORITY) values( ' user1 ' , ' ROLE_USER ' )
INSERT INTO AUTHORITIES(USERNAME,AUTHORITY) values( ' user2 ' , ' ROLE_USER ' )
这里我用的是acegi默认的数据结构,可以改只要你指定JdbcDaoImpl的authoritiesByUsernameQuery和usersByUsernameQuery属性就可以了。另AUTHORITIES表也要一同加入,原因acegi获得userDetail时,也会读取这个表的内容,否则会抛“nested exception is java.sql.SQLException: 对象名 'authorities' 无效”这个异常。
修改applicationContext.xml,变成如下:
<?xml version="1.0" encoding="UTF-8"?>
