[英]How to pass large number of parameters from Angular js to rest service
I am trying to fetch parameters from angular JS $http
service to rest service using ** @queryParam**
. 我正在尝试使用** @queryParam**
从有角JS $http
服务获取参数到其余服务。 I need to fetch lot of parameters(below have shown for 3 as an example ,but I need to use around 12-15 of them which I need to pass to the java side) ,so fetching all with @QueryParam makes the code look pretty bad .I am using GET
. 我需要获取很多参数(下面以3为例进行说明,但是我需要使用其中的12-15个参数,我需要传递给Java端),因此使用@QueryParam获取所有参数会使代码看起来很漂亮不好。我正在使用GET
。
How can I optimize this ? 我该如何优化呢?
Example what I am doing - 示例我在做什么-
Angular Js code - Angular Js代码-
$http({
url: someUrl,
method: "GET",
params: {filter1: $scope.filter1,
filter2:$scope.filter2,
filter3:$scope.filter3
});
Java side - Java端-
@path("/getAllData")
@GET
@Produces({..}
public response getAllData(@QueryParam("filter1") final String filter1,
@QueryParam("filter2") final String filter2,
@QueryParam("filter3") final String filter3){
}
Also ,wanted to know the optimization in case when I am building URL instead of params object, and picking the same with @PathParam
另外,想知道优化情况,以防我构建URL而不是params对象,并使用@PathParam
$http.get('rest/test/getAllData/?filter1='$scope.filter1 +
'&filter2='$scope.filter2 + '&filter3='$scope.filter3 +
'&filter4='$scope.filter4)
I am able to do it by passing individually in @QueryParam . 我可以通过在@QueryParam中单独传递来做到这一点。 I am looking for optimized code when we a large number of parameters. 当我们有大量参数时,我正在寻找优化的代码。
Create a POJO with all the required parameters. 使用所有必需的参数创建一个POJO。
In angular, do this 在角度,这样做
var obj = {};
obj.filter1 = $scope.filter1;
obj.filter2 = $scope.filter2;
obj.filter3 = $scope.filter3;
$http({
url: someUrl,
method: "GET",
params: obj
});
You can accept all the parameters in you rest like this - 您可以像这样接受休息中的所有参数-
@path("/getAllData")
@GET
@Produces({..}
public response getAllData(MyPojo obj){
//String filter1 = obj.filter1;
}
You can do it in 2 ways: 您可以通过2种方式来做到这一点:
1) org.json.simple.JSONObject
. 1) org.json.simple.JSONObject
。
2) Bean or POJO Class. 2)Bean或POJO类。
AngularJS Controller: AngularJS控制器:
var URL = appURL+'/adm/addCollProcess.do';
var json = {"col_pro_id":$scope.col_pro_id, "col_code": $scope.col_code, "exam_type_ids": $scope.exam_types.toString().replace("[","").replace("]",""),
"created_by" : "admin", "file_path" : $scope.file_path, "website" : $scope.website, "facebook" : $scope.facebook};
// using JSONObject
$http.post(URL, json).then(function(response){
if(response.data){
// Code
}
});
// using Bean Class
$http.post(URL, JSON.stringify(json)).then(function(response){
if(response.data){
// Code
}
});
Java Controller: Java控制器:
// using JSONObject
@RequestMapping(value="/addCollProcess.do", method=RequestMethod.POST)
public boolean addCollProcess(@RequestBody JSONObject json){
// Code
}
// using Bean Class:
@RequestMapping(value="/addCollProcess.do", method=RequestMethod.POST)
public @ResponseBody boolean addCollProcess(@RequestBody AdmissionProcessBean processBean) {
// Code
}
