Calculator.java package org.jboss.tutorial.security.bean; import javax.ejb.Remote; @Remote public interface Calculator { int add(int x, int y); int subtract(int x, int y); int divide(int x, int y); } CalculatorBean.java package org.jboss.tutorial.security.bean; import org.jboss.ejb3.security.SecurityDomain; import javax.ejb.MethodPermissions; import javax.ejb.Stateless; import javax.ejb.TransactionAttribute; import javax.ejb.TransactionAttributeType; import javax.ejb.Unchecked; @Stateless @SecurityDomain("other") public class CalculatorBean implements Calculator { @Unchecked //it\\\'s ok to delete this line,it means to use this method without checked @TransactionAttribute(TransactionAttributeType.REQUIRES_NEW) public int add(int x, int y) { return x + y; } @MethodPermissions({"student","teacher"}) //note that we can more role here public int subtract(int x, int y) { return x - y; } @MethodPermissions({"teacher"}) public int divide(int x, int y) { return x / y; } } 这里substract方式定义了访问对象：student和teacher ; divide 方式定义了访问对象为: teacher .可以看role.properties,当然也可以加入些自定义对象。 Client.java package org.jboss.tutorial.security.client; import org.jboss.security.SecurityAssociation; import org.jboss.security.SimplePrincipal; import org.jboss.tutorial.security.bean.Calculator; import javax.naming.InitialContext; public class Client { public static void main(String[] args) throws Exception { InitialContext ctx = new InitialContext(); Calculator calculator = (Calculator) ctx.lookup(Calculator.class.getName()); System.out.println("Everybody can add"); System.out.println("1 + 1 = " + calculator.add(1, 1)); System.out.println("Change role:Kabir is a student"); SecurityAssociation.setPrincipal(new SimplePrincipal("kabir")); SecurityAssociation.setCredential("validpassword".toCharArray()); System.out.println("Students are allowed to do subtraction but division"); System.out.println("1 - 1 = " + calculator.subtract(1, 1)); try { System.out.println("16/4="+calculator.divide(16, 4)); } catch (SecurityException ex) { System.out.println("Kabir try to do division:"+ex.getMessage()); } System.out.println("Change role:roson is a teacher"); SecurityAssociation.setPrincipal(new SimplePrincipal("roson")); SecurityAssociation.setCredential("sandy".toCharArray()); System.out.println("Teacher are allowed do substraction and division"); System.out.println("2 - 1 = " + calculator.subtract(2, 1)); System.out.println("16/4 = "+calculator.divide(16, 4)); } } 这里有两个人物分别为: kabir 是student 密码为 validpassword ; roson 是 teacher 密码为 sandy。 这两个人调用了减、除这两个方式程序将根据访问权限做相应的处理。 users.properties kabir=validpassword roson=sandy 里面是username=password这样的格式，一行一个用户。 roles.properties kabir=student roson=teacher 里面是username=role1,role2,role3，即用户和该用户所属的所有角色。 这里附上log4j.properties 在jboss-EJB-3.0_Preview_5.zip 里面没有这个老是显示缺少appender。有了这个将在该目录下生成个record.log日志文件 log4j.properties log4j.appender.R=org.apache.log4j.RollingFileAppender log4j.appender.R.File=record.log log4j.appender.R.layout=org.apache.log4j.PatternLayout log4j.appender.R.layout.ConversionPattern=%p %d{hh:mm:ss} %t %c{1} -%m%n log4j.appender.R.MaxBackupIndex=1 log4j.appender.R.MaxFileSize=100KB log4j.appender.stdout.layout=org.apache.log4j.PatternLayout log4j.appender.stdout.layout.ConversionPattern=%5p [%t] (%F:%L) -%m%n log4j.appender.stdout=org.apache.log4j.ConsoleAppender log4j.rootLogger=stdout,R 运行：参考installing.html Windows下 打开命令提示符cmd，到 jboss_home/bin Run.bat –c all 用ant 先build后run 就行了。 讨论： 由于对jaas接触的不多，只能尽力说说自己的一些想法和改过的地方。 返回类别: 教程 上一教程: JB2005 UPDATE 4 下一教程: Mini Java编译器（六） 您可以阅读与"Jboss EJB3.0 security"相关的教程: · Jboss Ejb3.0 Interceptor · Jboss Ejb3.0 Statefull Bean · Jboss Ejb3.0 Entity Bean · Lomboz中配置JBoss 4.0.1 · JBuilder2005+JBoss-4.0.2RC1+J2SDK1.5+Log4j 开发Session Bean例解（4） |
