large files Download in Java using FileCopyUtils.copy -

-

i wrote codes download files sever clients machines: 

   bufferedinputstream in = null;                 try {                     in = new bufferedinputstream(new fileinputstream(filenpath));                 } catch (filenotfoundexception e) {                      e.printstacktrace();                 }                 string mimetype = servletcontext.getmimetype(filenpath);                  response.setbuffersize(fsize);                 response.setcontenttype(mimetype);                  response.setheader("content-disposition", "attachment; filename=\""+ filename + "\"");                 response.setcontentlength(fsize);                    try {                     filecopyutils.copy(in, response.getoutputstream());                      in.close();                     response.getoutputstream().flush();                     response.getoutputstream().close();                   } catch (ioexception e) {                      e.printstacktrace();                 }

this code works fine files smaller 8m not larger files. grateful if guys give me hints.

thanks, nick

there not go on here. in tomcat there various ways set maximum file upload size.

for example in tomcat server.xml, there maxpostsize setting. not know enough server look.

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.
