To create after returning advice, create an <after-returning> element as a child of the <advice> element. Just like in the before advice, you need to set the method and pointcut or pointcut-ref attributes. In most cases, you would also want to know the return value; to obtain this, set the returning attribute to the name of an Object argument of the method. Finally, you can also use arg-names to specify the argument names of the method in the method attribute. Let s take a look at the code in Listing 6-48, which shows how we can create an aspect that will audit calls to every method and censor some return values. Listing 6-48.

If you keep encountering problems, sometimes it is better to start from scratch than it is to spend hours, days, or weeks troubleshooting an issue at this stage. Reinstalling sounds like it may be more time-consuming, but if you missed just one little check mark in a dialog box somewhere, it will be like looking for a needle in a haystack.

They write a query and design a report in the morning, perform database backups or restores in the afternoon, and update all the systems before heading home Fortunately, during external deployment of SSRS to our clients and internal deployment for my software development company, I (Rodney) have worn each of these hats on a day-today basis I have been entrenched in every deployment phase By developing efficient stored procedures, designing reports, testing security, and maintaining deployed reports as a content manager, I have witnessed the day-to-day operation of SSRS from many perspectives In addition to those roles, I have also been responsible for our company s overall strategy for building solutions to analyze and transform the data that s gathered through both our own and other third-party applications To that end, an essential part of my job was integrating SSRS into the overall BI strategy that incorporated the following:.

<aop:config> <aop:aspect id="firstAspect" ref="aspectBean"> <aop:after-returning method="auditCall" pointcut="execution(* com.apress.prospring2. ch06.services.*.*(..)) && target(target)" arg-names="target, ret" returning="ret"/> </aop:aspect> </aop:config> </beans> Notice that our pointcut expression specifies execution of any method in any class in the services package and that we are binding the invocation target to an argument called target. We are also going to receive the return value the target returned in the AspectBean.auditCall() method. Looking at the arg-names attribute, you can clearly see that the auditCall method needs two arguments, and because we want to receive a target of any type and process any type of return value, the type of the arguments needs to be Object. We can now write the code for the AspectBean.auditCall method (see Listing 6-49). Listing 6-49. The AspectBean auditCall Method public class AspectBean { public void auditCall(Object target, Object ret) { System.out.println("After method call of " + ret); if (ret instanceof User) { ((User)ret).setPassword("****"); } } } We now have the auditCall method with two arguments: target and ret. Notice that the XML configuration in Listing 6-48 file specified the argument names in the correct order. This is quite easy to get wrong. Luckily, some IDEs will detect this and suggest a correction; Figure 6-6 shows this error correction in IntelliJ IDEA when we swapped the order of arguments from the correct target, ret to ret, target.

The first task from a SQL Server standpoint is to create the right users and groups in the domain and then assign them the right permissions on each node so that SQL Server will function properly.

Figure 6-6. Arg-names error detection in IntelliJ IDEA You can see that the <after-returning> element gives you the same configuration options as the @AfterReturning annotation in @AspectJ.

To create the SQL Server service accounts, follow these steps: 1. Log on to one of the servers as an administrator who has rights to add accounts to the domain. 2. From Administrative Tools, start the Active Directory Users and Computers tool. 3. In the left pane, expand the domain, right-click Users, and select New User. 4. In the New Object User dialog box, you must enter at least a first name or a last name, as well as the user logon name. Figure 8-1 shows an example. Click Next.
