RE: [Springframework-developer] Attributes - any alternative for commons-attributes ?

[<jue...@we...>]

You mean the current version from Commons Attributes CVS? We plan to =
update to the current Commons Attributes snapshot for RC2; an official =
CA release would be preferable, but I guess we won't get that in time.
=20
BTW, I tried to update to a current Commons Attributes snapshot already =
for RC1, but our test suite failed then. Might be some minor semantic =
change in the CA API or compiler; I haven't had the time to figure this =
out.

for commons-attributes ?


Well.. I managed to get jakarta-commons-attributes to work by using the =
CVS version.
=20
Would it be possible to upgrade spring to use this by default ?


The version number of the jar that the cvs version builds is =
commons-attributes-compiler-2.0alpha.jar
=20
On a side note, I wish to use a =
org.springframework.transaction.interceptor.NameMatchTransactionAttribute=
Source as the default attribute source, allowing me to specify something =
like :
=20
<bean id=3D"matchMethodNamePattern" =
class=3D"org.springframework.transaction.interceptor.NameMatchTransaction=
AttributeSource">
    <property name=3D"properties">
        <props>
            <!-- read only methods -->
            <prop key=3D"list*">PROPAGATION_REQUIRED,readOnly</prop>
            <prop key=3D"find*">PROPAGATION_REQUIRED,readOnly</prop>
            <prop key=3D"get*">PROPAGATION_REQUIRED,readOnly</prop>
            <prop key=3D"load*">PROPAGATION_REQUIRED,readOnly</prop>
            <prop key=3D"read*">PROPAGATION_REQUIRED,readOnly</prop>
            <!-- the default is transactional (least specific, match =
everything) -->
            <prop key=3D"*">PROPAGATION_REQUIRED</prop>
        </props>
    </property>
</bean>

Then, I wish to use a commons attributes attribute source to override =
these defaults.
=20
How would I achieve this.
=20
I saw the jpetstore attribuites sample, using :
=20

<bean id=3D"transactionAttributeSource"
    =
class=3D"org.springframework.transaction.interceptor.AttributesTransactio=
nAttributeSource"
    autowire=3D"constructor">
</bean>
<bean id=3D"attributes" =
class=3D"org.springframework.metadata.commons.CommonsAttributes"/>
=20
but I can't work out how to 'nest' attribute sources as seems to be =
possible as described at=20
=20
http://www.springframework.org/docs/api/org/springframework/metadata/Attr=
ibutes.html
"...as it allows for hierarchical attribute sources..."
=20
Thanks,
=20
Cameron.

commons-attributes ?


I am trying to use commons-attributes to create transactional attributes =
for some beans.
=20
I can't seem to get the commons-attributes compiler to work .. it =
doesn't like my source code, see stack trace below.
=20
Before I dive into the source code for commons-attributes, I would like =
to ask if there are plans to support another metadata system.
=20
If there aren't plans, can you recommend another metadata system that I =
could investigate implementing myself.
=20
I have had a look at=20
  * attrib4j - it modifies the classes, which makes using eclipse a =
pain.
  * nanning attributes may work, though they don't offer instance based =
attributes ( only strings as far as I can see)
  * I am currently trying qdox attributes, but the jar they provide =
doesn't have the right classes.. I am trying a source build.
