aop-example

This project demonstrates the use of aop.

See: https://docs.spring.io/spring/docs/current/spring-framework-reference/core.html#aop

The project consists of the following sub-modules.

• common - contains the Java class objects shared by all projects
• feeder - a client that is deployed as a Gigaspaces Processing Unit that contains a remote GigaSpaces proxy and demonstrates the use of aop. The elapsed time of a GigaSpaces.read() method call is logged.
• space - a project defining a space

The feeder project has defined in the read-profiler.xml the advice and pointcut. This calls the action defined in the ClientReadProfiler.java when the call is made to GigaSpaces.read().

Deployment

1. Build the jar files. Go to the directory containing the project's main pom.xml. We will call this the $PROJ_DIR.

mvn package

2. Start the grid, for example,

$GS_HOME/bin/gs.sh host run-agent --manager --gsc=5 --webui

3. Deploy the jar found in space/target, for example,

$GS_HOME/bin/gs.sh pu deploy space-pu $PROJ_DIR/space/target/space-1.0-SNAPSHOT.jar

4. Deploy feeder/target/aop-example-feeder.jar, for example,

$GS_HOME/bin/gs.sh pu deploy feeder-pu $PROJ_DIR/feeder/target/feeder-1.0-SNAPSHOT.jar

5. Check gsc logs for the following message:

2018-03-05 16:19:43,957 aop-example-feeder [1] INFO [com.gigaspaces.demo.aop.ClientReadProfiler] - clientReadProfiler_gigaSpace_read_MyData took 23 ms. to run.
