json - How automatically parse response String into Map using RestTemplate -


i'm using resttemplate retrieve list of issues jira. response string lots of fields, of them arrays. request looks like:

 responseentity<string> response =  resttemplate.exchange(url, httpmethod.get, entity, string.class);

response string looks like:

{  "expand": "schema,names",  "total": 12,  "issues": [  {   "id": "32",   "key": "test-1",   "fields": {     "fixversions": [       {         "description": "",         "releasedate": "2017-04-02"       }     ] }, {   "id": "32",   "key": "test-2",   "fields": {     "fixversions": [       {         "description": "",         "releasedate": "2017-04-01"       }     ] } ]    }

is possible convert string map, object string or list of map or this, without defining appropriate objects. result, i'd have possibility access description by: response.getissues().get(0).getfields().getfixversion().get(0).getdescription()

in such occasion, defining chain of specific objects looks cumbersome.

you can create own pojo classes corresponds structure of response json. based on json have shared, can have class structure : 

public class response {     private string expand;     private string total;     private list<issues> issues; }  public class issues {     private string id;     private string key;     private map<string, list<fixversions> fields; }  public class fixversions {     private string description;     private string releasedata; }

your get call change following :

responseentity response = resttemplate.exchange(url, httpmethod.get, entity, response.class);

p.s. - fields in pojo class must have getters , setters well.

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...

verilog - Systemverilog dynamic casting issues -

i've code snippet following in testbench function void write_to_port( my_data_type_base data ); my_data_type_extended data_ext; if(!$cast(data_ext, data)); `uvm_error(get_type_name(), "failed cast"); `uvm_info(get_name(), $psprintf("data_ext :\n%s", data_ext.sprint()), uvm_medium) // write data_ext out port.... endfunction when run it, i'm getting uvm_error "failed cast." i'm not quire sure why $cast not returning 1. can see, i'm printing out extended class data item after casting uvm_info. can see it's being cast properly. if don't use $cast if condition, don't runtime error. isn't coding practice use if dynamic cast check if $cast returning 1 ? what might reason behind cast not returning 1 in above case? i think semicolon on line 'if' not belong? i think consumes if statement, , uvm_error executes regardless of how if evaluates: if(!$cast(data_ext, data)); <- no semico...
