Strix

Strix is a lightweight and simple transaction library using aspects to do the magic.

Simple Usage

In short terms you have to:

1. Include strix as dependency

   <dependency>
       <groupId>io.mcarle</groupId>
       <artifactId>strix</artifactId>
       <version>1.0.1</version>
   </dependency>
   

2. Include aspectj-maven-plugin and define strix as aspectLibrary

   <plugin>
       <groupId>org.codehaus.mojo</groupId>
       <artifactId>aspectj-maven-plugin</artifactId>
       <version>1.10</version>
       <executions>
           <execution>
               <goals>
                   <goal>compile</goal>
                   <goal>test-compile</goal>
               </goals>
           </execution>
       </executions>
       <configuration>
           <complianceLevel>${maven.compiler.source}</complianceLevel>
           <source>${maven.compiler.source}</source>
           <target>${maven.compiler.target}</target>
           <aspectLibraries>
               <aspectLibrary>
                   <groupId>io.mcarle</groupId>
                   <artifactId>strix</artifactId>
               </aspectLibrary>
           </aspectLibraries>
       </configuration>
   </plugin>
   

3. Start strix before you call any transactional methods

   import io.mcarle.strix.Strix;
   import org.glassfish.jersey.servlet.ServletContainer;
   
   public class ExampleServlet extends ServletContainer {
      
       @Override
       public void destroy() {
           super.destroy();
           Strix.shutdown();
       }
      
       @Override
       public void init() throws ServletException {
           Strix.startup();
           super.init();
       }
   }
   

4. Annotate your classes or methods, which should be transactional with strix’s @Transactional-Annotation like

   import io.mcarle.strix.annotation.Transactional;
   import static io.mcarle.strix.Strix.em;
   
   @Transactional
   public class ExampleManager {
      public <T> T find(Class<T> entityClass, Long id) {
           return em().find(entityClass, id);
      }
   }
