前言
本文主要介绍的是在angularjs中update两次出现$promise属性无法识别的解决方法，下面话不多说，先来看看错误提示，然后再看看解决的办法吧。
一、错误信息如下：
error 2015-12-02 14:33:17,653 http-bio-8080-exec-42 o.s.s.r.i.e.internalerrorexceptionmapper - unrecognized field "$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：
我要评论
// ===============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。
