EDIT

copied from #10055

there is a local feature branch "feature_10216_spring5"

Issues:

• unitils support (could override some classes but it does not work in cdmlib-remote for some reason)
• cdmlib-remote-webapp ClassifiationIT des not work due to failing @RequestMapping resolution
  • .json is not mapped correctly as content negotiation via pathExtensions is not sufficiently supported anymore by Spring >5.2(?), see deprecated method favorPathExtension() in CdmSpringMVCConfig.configureContentNegotiation()
  • can be workarounded by adding the .json version to the @RequestMapping, tested for ClassificationListController with @RequestMapping(value = {"/classification", "/classification.json"})
    
• all other tests are running
• also running TestModelUpdate works, so generally creating the spring5 application context works

Also important:

• also decide which spring version to use: #4608 (if not yet solved)

• use the encrypto Passwordencoder in UserService instead of the deprecated one

  • required for upgrading to spring-security 5.x

• we may want to further normalize spring config files: #5380

• check if TaxonNodeByNameComparator is needed as spring bean as it is currently the case

• spring 6 issues copied to #10226
