java - Share RestTemplate's MessageConverters across multiple instances -

-

benchmarks made showed 70% of time creating new resttamplate() messageconverters, wondered if it's safe create 1 set of converters , use across multiple instances, different threads.

edit: motivation logging "on wire" traffic. thought implementing using clienthttprequestinterceptor. since each request should logged different file, thought create new resttemplate each set of requests, different interceptor.

this javadoc of httpmessageconverter doesn't explicitly require it, intention implementations thread safe. if thread safe, safe use across multiple resttemplate instances.

resttemplate other http client use. shouldn't typically need more 1 instance per application. (some exceptions exist proxies, ssl configurations, etc.)

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
