java - Discover methods without @Transaction? -


i'm struggling validation implement. verify every methods service start update must have @transactional annotation. far have made concept gives me methods service class start update (e.g. updateinvoice). have no idea how build constraint select methods wich have no @transaction annotation.

i'd recommend define concepts representing key elements define constraints on them, i.e.

your services:

<concept id="service:serviceclass">   <description>adds label "service" every class annotated "@com.mycompany.services.service"</description>   <cypher><![cdata[   match     (service:type:class)-[:annotated_by]->()-[:of_type]->(serviceannotationtype)   set     service:service       serviceannotationtype.fqn = "com.mycompany.services.service"   return     service      ]]>   </cypher> </concept>

your transacted methods:

<concept id="service:transactmethod">   <description>adds label "transact" every method annotated "@com.mycompany.services.transact"</description>   <cypher><![cdata[   match     (method:method)-[:annotated_by]->()-[:of_type]->(transactannotationtype)   set     method:transact       transactannotationtype.fqn = "com.mycompany.services.transact"   return     method      ]]>   </cypher> </concept>

your constraint:

<constraint id="service:allupdatemethodsmustbetransacted">   <requiresconcept refid="service:serviceclass" />   <requiresconcept refid="service:transactmethod" />   <description>all update methods must transacted</description>   <cypher><![cdata[   match     (service:service:class)-[:declares]->(updatemethod:method)       updatemethod.name =~ "update.*" // extracted concept     , not updatemethod:transact   return     updatemethod   ]]>   </cypher> </constraint >

this approach has several advantages:

  • you're getting more rules each of them better readable (especially constaint), because you're using terms defined design
  • it's need concepts "service" , "transact" other constraints - use labels
  • if you're creating maven site report concepts in design (i.e. wich service implementations exist)

morning, i have code takes string of shoe sizes, explodes , puts in table. code works , info displayed correctly on page after table there few 1's after table. i'm confused this. so table looks (in columns of 3 on webpage) available in following sizes: 3 4 5 6 9 10 111 here's codes, purpose of example $x = 3|4|6|10|9 function get_sizes_pipe($x) { $counter = 0; $splits = explode("|",$x); asort($splits); $x = print "<table class='greentable'>"; $x .= print "<thead><tr><th scope='col' colspan='3' abbr='starter'>available in following sizes:</th></tr></thead><tbody><tr>"; foreach ($splits $split) { $entry = print "<td>".$split."</td>"; if($counter == 2){ $entry .= print "</tr><tr>"; $counter =0; } else { $counter++; ...
