java - Spring MockMvc UnsupportedOperationException after upgrading to new spring version -

i'm working on migration spring 3.2.3.release spring 4.2.0.release. got stuck because existing tests start failing. code looks (simplified):

@webappconfiguration @contextconfiguration(classes = [testconfig.class]) class mvctest extends specification {      @autowired     webapplicationcontext context     mockmvc mockmvc      @subject     mycontroller controller      def setup() {         controller = new mycontroller()         mockmvc = mockmvcbuilders.standalonesetup(controller).build()     }      def "should not allow save invalid entity"() {     when:      def result = mockmvc.perform(post("/people")                                          .content('''{                                             "name": "",                                             "age": 21,                                             "sex": 1                                          }''')                                          .contenttype(mediatype.application_json)                                          .accept(mediatype.application_json))      then:     result.anddo(print())           .andexpect(status().isbadrequest())           .andexpect(jsonpath('$.message').value("name cannot empty."))     } } 

mycontroller.java

@controller public class mycontroller {      @requestmapping(method = requestmethod.post,              value = "/people",              produces = "application/json",              consumes = "application/json")     @responsebody     public response create(@requestbody @valid person person) {         //save person repository. debugger not entering line...     } } 

person.java:

public class person {      private int age;      @notempty(message = "name cannot empty.")     private string name;      @notnull     @jsonserialize(using = sextypeserializer.class)     @jsondeserialize(using = sextypedeserializer.class)     private sex sex;      //getters, setters, other methods } 

testconfig.groovy

@enablewebmvc @configuration class testconfig {      @bean     @primary     public objectmapper objectmapper() {         def objectmapper = new objectmapper()         def jacksonmodule = new simplemodule()         jacksonmodule.adddeserializer(sex.class, new sextypedeserializer())         jacksonmodule.addserializer(sex.class, new sextypeserializer())          objectmapper.registermodule(jacksonmodule)         objectmapper     } }

custom serializers provided , working correctly previous version of spring. think there wrong configuration, because of fact such method being called:

stubwebapplicationcontext.java

@override public <t> t createbean(class<t> beanclass) {     throw new unsupportedoperationexception(); } 

looks other implementation of createbean should used. ideas problem?

this breaking change introduced in spring framework 4.1.3.

i have created bug report make sure gets resolved:

https://jira.spring.io/browse/spr-13375

thanks bringing our attention!

by way, when use mockmvcbuilders.standalonesetup(), there no need load applicationcontext via @contextconfiguration , @webappconfiguration. if analyze test class, see in fact not using webapplicationcontext have @autowired test. can safely remove of configuration.

note testconfig not used in mockmvc since using mockmvcbuilders.standalonesetup() test instance of controller directly. in other words, custom sextypedeserializer not used in test configured this. if want continue use stand-alone setup, can configure mappingjackson2httpmessageconverter custom configured objectmapper (along custom serializer, etc.) , pass standalonemockmvcbuilder via setmessageconverters(...) method.

as alternative, consider using mockmvcbuilders.webappcontextsetup(context) in order use sextypedeserializer in tests along rest of production spring mvc configuration.
