java - How to avoid stacktrace HTTP Status 500 page with MaxUploadSizeExceededException -

-

i have code (like in spring's reference):

<bean id="multipartresolver"      class="org.springframework.web.multipart.commons.commonsmultipartresolver">         <!-- 1 of properties available; maximum file size in bytes -->         <property name="maxuploadsize" value="100000"/> </bean>

when user tries upload file on 100 kb server error page http status 500 , stacktrace displayed. how avoid in simplest way? redirect form page , show own error message.

assuming it's org.springframework.web.multipart.maxuploadsizeexceededexception, define error-page in web.xml follows:

<error-page>     <exception-type>org.springframework.web.multipart.maxuploadsizeexceededexception</exception-type>     <location>/upload-error.jsp</location> </error-page>

note works when don't have <error-page> covers servletexception or 1 of superclasses. otherwise you've bring in exception filter unwraps , rethrows root cause of servletexception.

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.
