版本声明：Activiti 5.22.0异步

需求：Activiti对接业务数据库后，使用自定义的用户和角色表代替Activiti原生用户、角色组等功能（实现详情见这篇文章：https://www.jianshu.com/p/45341b440316） 后，其在线流程设计器在设置任务节点的办理人时，若是能作到直接勾选自定义库的办理人、候选人、候选组，其体验相信会上升一个台接。下面将介绍下实现思路：url

一、重写设定办理人界面：spa

<div style="width:100%;height:100%;" class="modal" ng-controller="KisBpmAssignmentPopupCtrl">
	<div style="width:80%;height:100%;" class="modal-dialog">
		<div class="modal-content">
			<div class="modal-header">
				<button type="button" class="close" data-dismiss="modal"
					aria-hidden="true" ng-click="close()">&times;</button>
				<h2 translate>PROPERTY.ASSIGNMENT.TITLE</h2>
			</div>
			<div class="modal-body">
				<div class="row row-no-gutter">
					<div class="col-xs-4">
						<div class="row row-no-gutter">

									placeholder="{{'PROPERTY.ASSIGNMENT.ASSIGNEE_PLACEHOLDER' | translate}}" />
							</div>
						</div>
		
						<div class="row row-no-gutter">
							<div class="form-group">
								<label for="userField">{{'PROPERTY.ASSIGNMENT.CANDIDATE_USERS'
									| translate}}</label>
								<div ng-repeat="candidateUser in assignment.candidateUsers">

										ng-model="candidateUser.value"
										ng-click="selectCandidate()" /> <i

										ng-click="addCandidateUserValue($index)"></i>
								</div>
							</div>
		
							<div class="form-group">
								<label for="groupField">{{'PROPERTY.ASSIGNMENT.CANDIDATE_GROUPS'

								<div ng-repeat="candidateGroup in assignment.candidateGroups">

								</div>
							</div>
						</div>
					</div>
					<div class="col-xs-8">
						<span class="mb10">

							</select>
						</span>
						<div style="min-height:350px;" class="default-grid ng-scope ngGrid ng1521010657341 unselectable" ng-grid="gridOptions"></div>
					</div>
				</div>
			</div>
			
			<div class="modal-footer">
				<!--  <button ng-click="close()" class="btn btn-primary" translate>ACTION.CANCEL</button>-->
				<button ng-click="save()" class="btn btn-primary" translate>ACTION.SAVE</button>
			</div>
		</div>
	</div>
</div>

二、重写properties-assignment-controller.js，废话很少说，先上代码：设计

        	}
            return true;

            minWidth: 100,  
            width : '25%'  
        },  
        {  
            field : 'realName',   
            displayName : '姓名',  
            minWidth: 100,  
            width : '25%'  
        }       
    ];
    $scope.displayText = function(enterpriseType){
    	var tmp = '';
    	switch(enterpriseType){
    	case 0:
    		tmp = '运营';
    		break;
    	case 1:
    		tmp = '银行';

    		break;
    	}
    	return tmp;
    }
    //选择用户组时表头
    $scope.groupColumns = [          
        {  
            field : 'pkid',  
            type:'number',  
            displayName : '角色Id',  
            minWidth: 100,  
            width : '16%'  
        }, 
        {  
            field : 'roleCode',   
            displayName : '角色code',  
            minWidth: 100,  
            width : '16%'  
        }, 
        {  
            field : 'name',   
            displayName : '角色名称',  
            minWidth: 100,  
            width : '25%'  
        },  
        {  
            field : 'type',
            type:'number',  
            displayName : '角色类型',  
            minWidth: 100,  
            width : '18%',
            cellTemplate : '<span>{{row.entity.type==1?"公有":"私有"}}</span>'
        },  
        {  
            field : 'enterpriseType',    
            displayName : '业务类型',  
            minWidth: 100,  
            width : '18%'
            ,cellTemplate : '<span>{{displayText(row.entity.enterpriseType);}}</span>'
        }  
    ];
    
    //代理人(审批人)
    $scope.selectAssignee = function () {
    	$scope.selectType = 0;
    	$scope.selectTitle = '选择代理人';
    };
    
    //候选人
    $scope.selectCandidate = function () {
    	$scope.selectType = 1;
    	$scope.selectTitle = '选择候选人';   
    };
    
    //候选组
    $scope.selectGroup = function () {
    	$scope.selectType = 2;
    	$scope.selectTitle = '选择候选组';
    };

}];
//声明----若是有此 contains 直接用最好
function array_contain(array, obj){
    for (var i = 0; i < array.length; i++){
        if (array[i].value == obj)//若是要求数据类型也一致，这里可以使用恒等号===
            return true;
    }
    return false;
}

核心： 一、设定办理人界面须要渲染一个数据表格：代理

//表格属性配置
    $scope.gridOptions = {  
		data: $scope.gridDataName,
		multiSelect: false,//不可多选
		enablePaging: true,
		pagingOptions: $scope.pagingOptions,
		totalServerItems: 'totalServerItems',
		i18n:'zh-cn',  
		showFooter: true,
	    showSelectionCheckbox: false, 
	    columnDefs : $scope.columnDataName,
        beforeSelectionChange: function (event) {
        	var data = event.entity.pkid;
            
            if($scope.selectType == 0){//选代理人
            	event.entity.checked = !event.selected;
            	$scope.assignment.assignee = data;
            }else if($scope.selectType == 1){//候选人
            	var obj = {value: data};
            	if(!array_contain($scope.assignment.candidateUsers, obj.value)){
            		$scope.assignment.candidateUsers.push(obj);
            	}                 	               	
        	}else if($scope.selectType == 2){//候选组
        		var obj = {value: $scope.getGroupData(event.entity)};
            	if(!array_contain($scope.assignment.candidateGroups, obj.value)){
            		$scope.assignment.candidateGroups.push(obj);
            	} 
        	}
            return true;
        }
    };

二、须要请求用户列表和角色列表的接口，而后办理人界面进行加载：code

//异步请求表格数据
    $scope.getPagedDataAsync = function(pageNum, pageSize, projectId){    	
    	var url;
    	if($scope.selectType == 2){
    		url = '/model/getGroupList';
    		$scope.columnData = $scope.groupColumns;
    	}else{
    		url = '/model/getUserList';
    		$scope.columnData = $scope.userColumns;
    	}
    	$http({
            method: 'POST',
            url: ACTIVITI.CONFIG.contextRoot+url,
            params:{
            	'pageNum': pageNum,
            	'pageSize': pageSize,
            	'projectId': projectId
            },
        }).then(function successCallback(response) {
                $scope.gridData = response.data.rows;               
                $scope.totalServerItems = response.data.total;
            }, function errorCallback(response) {
                // 请求失败执行代码
            	$scope.gridData = [];
            	$scope.totalServerItems = 0;
        });
    }

三、监听左侧切换选择办理人、候选人、候选组时表格从新加载数据：当选择办理人和候选人时，右侧加载用户列表，当选择候选组时右侧加载角色列表，并注意动态变换表格表头；orm

//代理人(审批人)
    $scope.selectAssignee = function () {
    	$scope.selectType = 0;
    	$scope.selectTitle = '选择代理人';
    };
    
    //候选人
    $scope.selectCandidate = function () {
    	$scope.selectType = 1;
    	$scope.selectTitle = '选择候选人';   
    };
    
    //候选组
    $scope.selectGroup = function () {
    	$scope.selectType = 2;
    	$scope.selectTitle = '选择候选组';
    };

表头：blog

//选择用户时表头
    $scope.userColumns = [          
        {  
            field : 'pkid',  
            type:'number',    
            displayName : '用户Id',  
            minWidth: 100,  
            width : '18%'  
        },            
        {  
            field : 'nickName',  
            displayName : '昵称',  
            minWidth: 100,  
            width : '25%'  
        },  
        {  
            field : 'loginName',  
            displayName : '登陆名',  
            minWidth: 100,  
            width : '25%'  
        },  
        {  
            field : 'realName',   
            displayName : '姓名',  
            minWidth: 100,  
            width : '25%'  
        }       
    ];
    $scope.displayText = function(enterpriseType){
    	var tmp = '';
    	switch(enterpriseType){
    	case 0:
    		tmp = '运营';
    		break;
    	case 1:
    		tmp = '银行';
    		break;
    	case 2:
    		tmp = '核心';
    		break;
    	case 3:
    		tmp = '链属';
    		break;
    	default:
    		tmp = 'N/A';
    		break;
    	}
    	return tmp;
    }
    //选择用户组时表头
    $scope.groupColumns = [          
        {  
            field : 'pkid',  
            type:'number',  
            displayName : '角色Id',  
            minWidth: 100,  
            width : '16%'  
        }, 
        {  
            field : 'roleCode',   
            displayName : '角色code',  
            minWidth: 100,  
            width : '16%'  
        }, 
        {  
            field : 'name',   
            displayName : '角色名称',  
            minWidth: 100,  
            width : '25%'  
        },  
        {  
            field : 'type',
            type:'number',  
            displayName : '角色类型',  
            minWidth: 100,  
            width : '18%',
            cellTemplate : '<span>{{row.entity.type==1?"公有":"私有"}}</span>'
        },  
        {  
            field : 'enterpriseType',    
            displayName : '业务类型',  
            minWidth: 100,  
            width : '18%'
            ,cellTemplate : '<span>{{displayText(row.entity.enterpriseType);}}</span>'
        }  
    ];
