标签:++ 展示 res $scope data 前端 function list 外部
场景:
本系统用的Mybatis分页插件PageHelper,调用了外部系统返回的数据为String类型的JSON串,数据量毕竟多,界面需要分页展示。
解决思路:
返回数据转List,然后把多个List放到一个List里,然后在从这个List里进行分页,前端只需要传一个页码过来即可,
部分代码如下:
Service代码
ResponseMsg<AppResp> responseMsg = new ResponseMsg<>();
int currentPage = req.getCurrentPage();
int pageSize = req.getPageSize();
String str= "[{"id":1546051323216,"name":"TPCE测试流程"},{"id":1546051343822,"name":"TPC-DS测试流程"}]";//例子
List list = JSONArray.parseArray( str );
List<Object> objects = new ArrayList<>();
int num = (currentPage > 1 ? (currentPage - 1) * pageSize : 0);
assert list != null;
for (int i = 0; i < pageSize && i < list.size() - num; i++) {
objects.add( list.get( num + i ) );
}
AppResp appResp = new AppResp();
appResp.setList( objects );
responseMsg.setResult( appResp );
responseMsg.setCurrentPage( currentPage );
responseMsg.setTotal( list.size() );
js代码:
$scope.list = [];
$scope.currentPage = 1;
$scope.pageSize = 10;
$scope.getProcessList = function () {
PARAM_BODY.currentPage = $scope.currentPage;
PARAM_BODY.pageSize = $scope.pageSize;
$http({
method: ‘POST‘,
url: options.app_api + ‘/app/getProcessList‘,
data: JSON.stringify(PARAM_BODY)
}).success(function (data) {
$scope.list = data.result.list;
$scope.currentPage = data.currentPage;
$scope.total = data.total;
});
};
