-

i java developer. want develop web site own. want choose rapid web application framework. have experience of spring mvc. wondering if should choose web framework. here list of want:

  1. rapid develop
  2. easy secure
  3. easy validate
  4. easy communicate db(mysql or nosql)

i have heard ruby,python,groovy , scala. should include these choices? how effort these take? should invest time on these or stay in java world? please kindly give me advices.

thanks lot.

if you're willing consider python (sounds are), should check out web2py.

  1. it's primary goals ease of use, rapid development, , security.
  2. more on security here , here
  3. if "easy validate" mean input/form validation, has great forms , validation system.
  4. for easy , portable database communication, has database abstraction layer works sqlite, postgresql, mysql, oracle, mssql, firebird, db2, informix, ingres, , google app engine (i.e., bigtable), partial support couchdb.

it's easy set , try out -- download, unzip, , run it. requires no installation or configuration, has no dependencies (the binary distribution includes own python interpreter), , includes ssl-enabled web server, relational database, scaffolding application, , web-based ide/administrative interface error logging , ticketing system. it's well-integrated, full-stack framework lots of features, including caching, session management, internationalization, authentication , role-based access control, web services, ajax, etc.

i'm not familiar spring mvc, think you'll find web2py less verbose. example, see this spring mvc tutorial -- below equivalent code in web2py (actually, web2py code adds field validation, js datepicker, , image upload):

from gluon.tools import crud db=dal('sqlite://storage.sqlite') crud=crud(globals(), db)  db.define_table('person',     field('name', required=true'),     field('birthdate', 'datetime'),     field('address', 'text'),     field('image', 'upload'))  def index():      db.person.id.represent=lambda id: a('view', _href=url('show', args=id))      return dict(people=db(db.person).select(),                  new=a('new contact', _href=url('edit'))) def edit():      row=db.person(request.args(0))      return dict(form=crud.update(db.person, row, next='show/[id]')  def show():      row=db.person(request.args(0)) or redirect(url('index'))      return dict(form=crud.read(db.person, row),                  link=a('edit', _href=url('edit', args=row.id)))

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.
