一、错误信息如下:
error 2015-12-02 14:33:17,653 http-bio-8080-exec-42 o.s.s.r.i.e.internalerrorexceptionmapper - unrecognized field "$promise" (class com.inetpsa.fnd.rest.client.clientrepresentation), not marked as ignorable (6 known properties: "lastname", "address", "telephone", "clientid", "mail", "firstname"]) at [source: org.apache.catalina.connector.coyoteinputstream@1b9d797d; line: 1, column: 357] (through reference chain: com.inetpsa.fnd.rest.client.clientrepresentation["$promise"]) com.fasterxml.jackson.databind.exc.unrecognizedpropertyexception: unrecognized field "$promise" (class com.inetpsa.fnd.rest.client.clientrepresentation), not marked as ignorable (6 known properties: "lastname", "address", "telephone", "clientid", "mail", "firstname"]) at [source: org.apache.catalina.connector.coyoteinputstream@1b9d797d; line: 1, column: 357] (through reference chain: com.inetpsa.fnd.rest.client.clientrepresentation["$promise"]) at com.fasterxml.jackson.databind.exc.unrecognizedpropertyexception.from(unrecognizedpropertyexception.java:51) ~[jackson-databind-2.4.4.jar:2.4.4] at com.fasterxml.jackson.databind.deserializationcontext.reportunknownproperty(deserializationcontext.java:744) ~[jackson-databind-2.4.4.jar:2.4.4] at com.fasterxml.jackson.databind.deser.std.stddeserializer.handleunknownproperty(stddeserializer.java:915) ~[jackson-databind-2.4.4.jar:2.4.4] at com.fasterxml.jackson.databind.deser.beandeserializerbase.handleunknownproperty(beandeserializerbase.java:1306) ~[jackson-databind-2.4.4.jar:2.4.4] at com.fasterxml.jackson.databind.deser.beandeserializerbase.handleunknownvanilla(beandeserializerbase.java:1284) ~[jackson-databind-2.4.4.jar:2.4.4] at com.fasterxml.jackson.databind.deser.beandeserializer.vanilladeserialize(beandeserializer.java:243) ~[jackson-databind-2.4.4.jar:2.4.4] at com.fasterxml.jackson.databind.deser.beandeserializer.deserialize(beandeserializer.java:118) ~[jackson-databind-2.4.4.jar:2.4.4]
二、问题代码
angular 自动会在返回的data数据中带上$promise属性。
在进行下面copy时将从data返回的数据copy到当前行用来显示,这样在进行update的操作时带的数据体中就包含了$promise属性,结果就会出现上述错误导致update失败。
三、更改如下:
// ===============show the update modal dialog ================== $scope.temprowentityforupdate; $scope.openupdateclientpopup=function(){ $scope.form1.$setsubmitted(true); $scope.temprowentityforupdate = {}; angular.copy($scope.currentselectedrowentity, $scope.temprowentityforupdate); angular.element('#updatedialog').modal({ backdrop: false }); }; $scope.updateclient=function(){ if($scope.form1.$submitted && $scope.form1.$valid){ client.update({},$scope.temprowentityforupdate,function(){ angular.copy($scope.temprowentityforupdate,$scope.currentselectedrowentity); }); angular.element('#updatedialog').modal('hide'); } };
解决办法:不使用更新后获得的data数据,而是从当前的行模型中取得数据copy给当前选中的行即可。
