UML class diagram for the before advice classes We now want to secure the StockService so that we can only call its methods after we have logged in. In fact, we ll say that we want to secure all classes in the com.apress.prospring2.ch06. services package so that we don t have to worry about security in the future. A na ve attempt at implementation of the before advice is in Listing 6-20. Listing 6-20. Na ve Implementation of the Before Advice @Aspect public class BeforeAspect { @Before("execution(* com.apress.prospring2.ch06.services.*.*(..))") public void beforeLogin() throws Throwable { if (SecurityContext.getCurrentUser() == null) throw new RuntimeException("Must login to call this method."); } } At first glance, this looks absolutely fine. To test the advice, we will combine the BeforeAspect with the XML configuration in Listing 6-21. birt qr code download, code 128 word barcode add in, birt gs1 128, word upc-a, birt ean 13, insert barcode in word 2007 winforms ean 13 reader EAN-13 Reader for .NET read EAN-13 barcode images in .NET ...

The XML Configuration File for the Before Advice < 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:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd"> <bean id="userService" class="com.apress.prospring2.ch06.services.UserService"/> <bean id="stockService" class="com.apress.prospring2.ch06.services.StockService"/> <bean class="com.apress.prospring2.ch06.before.BeforeAspect"/> <aop:aspectj-autoproxy /> </beans> We have the BeforeAspect as a Spring bean, and we use the aspectj-autoproxy: we can therefore use the code from Listing 6-22 to access the advised services. Listing 6-22. Sample Application for the Before Advice public class BeforeDemo { public static void main(String[] args) { ApplicationContext ac = new ClassPathXmlApplicationContext( "/META-INF/spring/beforedemo1-context.xml" ); StockService stockService = (StockService) ac.getBean("stockService"); System.out.println(stockService.getStockLevel("ABC")); } } When we run the application, it fails with a RuntimeException with the message Must login to call this method. Great, it works! To test that we can call the service methods after logging in, we will add a call to get the UserService bean and call its login method. Listing 6-23 shows a code fragment that does just that. Listing 6-23. Code Fragment to Get the UserService and login UserService userService = (UserService) ac.getBean("userService"); userService.login("janm"); The trouble is that the login method is also in a class in the services package; therefore, it is advised by the beforeLogin advice. Thus, we cannot log in, because we re not logged in. We ll need to modify our pointcut expression to exclude the login method. We can write the pointcut expression directly, but we re going to create two private @pointcut expressions and use them in the before advice s pointcut expression. Listing 6-24 shows how we ve implemented the change. Listing 6-24. Change to the BeforeAspect @Aspect public class BeforeAspect { winforms ean 13 reader Free BarCode API for .NET - CodePlex Archive

NET WinForms fn_syspolicy_is_automation_enabled (shown in Listing 6-3). If Policy-Based Management is enabled, the job proceeds to the next step, which uses PowerShell to invoke the Policy Engine and evaluate the policy. Listing 6-3. Function used to determine if Policy-Based Management is enabled CREATE FUNCTION fn_syspolicy_is_automation_enabled() RETURNS bit AS BEGIN DECLARE @ret bit; SELECT @ret = CONVERT(bit, current_value) FROM msdb.dbo.syspolicy_configuration WHERE name = 'Enabled' RETURN @ret; END Notice that the function in Listing 6-3 uses the syspolicy_configuration view we discussed in the Properties section earlier in the chapter. You can create your own job in SQL Server that uses the function in Listing 6-3 to make sure PolicyBased Management is enabled using the script in Listing 6-4. If the job fails, you could send an alert notification informing you that Policy-Based Management is disabled. Listing 6-4. Script to see if Policy-Based Management is enabled IF (msdb.dbo.fn_syspolicy_is_automation_enabled() != 1) BEGIN RAISERROR(34022, 16, 1) END So for traceability, we can use all existing unit tests when doing bug fixes or change requests in production, and quickly see if, and where, the new code broke anything existing. This will not give us good traceability on its own. We need a good way to directly see what requirements (work items) were covered by the failed unit test. This can be done by forcing the developers to associate a work item ID with each check-in and hence with the unit tests that were created for that check-in. When a unit test fails, we can see which work items were the base for the bug fix by using the work item tracking functionality, and more easily find information about the bug fix and the original requirement.
