java - How to enable enums directive in Struts2 for FreeMarker results? -

-

say have enum class "sample.enums.enum", , have struts2 applications default configuration part.

if configure beanwrappers correctly, should work.

${enums["java.math.roundingmode"].up}

it not work. how configure struts2 freemarker configuration allow enums directive.

i.e.

root.put("enums", beanswrapper.getdefaultinstance().getenummodels());

ok not difficult, extend freemarkermanager , override 

@override public simplehash buildtemplatemodel(valuestack stack, object action, servletcontext ervletcontext, httpservletrequest request, httpservletresponse response, objectwrapper wrapper)

in method, set enums hash model on model. set struts property,

<constant name="struts.freemarker.manager.classname" value="your.freemarker.configclass">

c# - Is it possible to remove an existing registration from Autofac container builder? -

something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ...

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
