c# - Seralization issue in WebApi 2.0 -


i developing rest api using ef 6.0 code first, automapper , webapi 2.0.

i struggling serializing data, or more specific; selecting should serialized when responding request.

lets creating app a football league has following classes:

public class player {     public string name { get; set; }     public virtual icollection<team> teams { get; set; } // example }  public class team {     public string name { get; set; }     public virtual icollection<team> players { get; set; }     public virtual icollection<footballgame> games { get; set; } }  public class footballgame {     public team team1 { get; set; }     public team team2 { get; set; }     public datetime datetime { get; set; } }

i have api controller named playerscontroller, , normal method url/api/players/id should return player.

however, due lazyloading, serialization , many-to-many relations every object related player returned:

{   "$id": "1",   "id": 1,   "name": "jon jones",   "teams": [     {       "$id": "2",       "id": 1,       "name": "liverpool",       "players": [         {           "$id": "3",           "id": 2,           "name": "james white",           "teams": [             {               "$ref": "2"             },             {               "$id": "4",               "id": 2,               "name": "man utd",               "players": [                 {                   "$ref": "3"                 },                 {                   "$id": "5",                   "id": 3,                   "name": "john snow",                   "teams": [                     {                       "$ref": "2"                     },                     {                       "$ref": "4"                     }                   ]                 },                 {                   "$ref": "1"                 }               ],               "games": [                 {                   "$id": "6",                   "id": 1,                   "team1": {                     "$ref": "2"                   },                   "team2": {                     "$ref": "4"                   },                   "datetime": "2014-08-18t23:20:01.7797942+02:00"                 },                 {                   "$id": "7",                   "id": 2,                   "team1": {                     "$id": "8",                     "id": 3,                     "name": "man city",                     "players": [                       {                         "$ref": "1"                       },                       {                         "$ref": "3"                       },                       {                         "$id": "9",                         "id": 4,                         "name": "elton john",                         "teams": [                           {                             "$ref": "2"                           },                           {                             "$ref": "8"                           }                         ]                       }                     ],                     "games": [                       {                         "$ref": "7"                       },                       {                         "$id": "10",                         "id": 5,                         "team1": {                           "$ref": "2"                         },                         "team2": {                           "$ref": "8"                         },                         "datetime": "2014-08-18t23:20:01.7807943+02:00"                       }                     ]                   },                   "team2": {                     "$ref": "4"                   },                   "datetime": "2014-08-18t23:20:01.7807943+02:00"                 }               ]             },             {               "$ref": "8"             }           ]         },         {           "$ref": "5"         },         {           "$ref": "9"         }       ],       "games": [         {           "$ref": "6"         },         {           "$ref": "10"         }       ]     },     {       "$ref": "4"     }   ] }

how can in easy way choose return player, , teams, rather return url team can data can obtained, like:

{   "id": 1,   "name": "jon jones",   "teams": "http://url/api/player/1/teams/" }

edit: disabeling lazyloading suggested, get:

{   "id": 1,   "name": "jon jones",   "teams": [] }

if thats way go, there "best practice" add uri teams in there?

you should disable lazy loading when building webservices - it's force explicit data being fetched. alternative drop [jsonignore] attributes on properties of classes don't want serializer at.

java - How to specify maven bin in eclipse maven plugin? -

i have eclipse maven plugin coming on centos. how can execute maven command on linx like: mvn clean package [abigail@localhost ~]$ mvn bash: mvn: command not found how should specify path executable of maven plugin in eclipse? or have install maven seperately？ thanks. eclipse (m2e) have bundled central parts of maven inside eclipse plugin, why not detected, , not usable. investigation find correct way bootstrap it, have create launcher file manually. if want run maven outside of eclipse, far better off standalone version of maven. mvn command bootstrap maven runtime system correctly, , secondly, able use advice concerning use of maven. maven binaries quite stable, wouldn't need upgrade upgrade eclipse. you can subsequently switch eclipse use external installation if prefer.
