本文目的：
针对自定义的用户、角色表，对Activiti的在线流程设计器进行优化改造，使之能直接在图形界面上完成对节点办理人、候选人、候选组的配置，不需要先去查数据库中的用户ID、角色ID等信息再填入。
先上一张实现效果图：

1、页面改造

修改上图中的页面，主要是修改页面布局，以及将输入框添加一些事件，代码如下：
<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()">×</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">
<div class="form-group">
<label for="assigneeField">{{'PROPERTY.ASSIGNMENT.ASSIGNEE'
| translate}}</label> <input type="text" id="assigneeField"
class="form-control" ng-model="assignment.assignee"
ng-click="selectAssignee()"
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">
<input id="userField" class="form-control" type="text"
ng-model="candidateUser.value"
ng-click="selectCandidate()" /> <i
class="glyphicon glyphicon-minus clickable-property"
ng-click="removeCandidateUserValue($index)"></i> <i
ng-if="$index == (assignment.candidateUsers.length - 1)"
class="glyphicon glyphicon-plus clickable-property"
ng-click="addCandidateUserValue($index)"></i>
</div>
</div>
<div class="form-group">
<label for="groupField">{{'PROPERTY.ASSIGNMENT.CANDIDATE_GROUPS'
| translate}}</label>
<div ng-repeat="candidateGroup in assignment.candidateGroups">
<input id="groupField" class="form-control" type="text"
ng-model="candidateGroup.value"
ng-click="selectGroup()" />
<i class="glyphicon glyphicon-minus clickable-property"
ng-click="removeCandidateGroupValue($index)"></i>
<i ng-if="$index == (assignment.candidateGroups.length - 1)"
class="glyphicon glyphicon-plus clickable-property"
ng-click="addCandidateGroupValue($index)"></i>
</div>
</div>
</div>
</div>
<div class="col-xs-8">
<span class="mb10">
<strong>{{selectTitle}}</strong>
<select class="pull-right" ng-change="change(selectedProject)"
id="project" ng-if="projects.length>0" ng-model="selectedProject" ng-options="project.pkid as project.projectName for project in projects">
</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>
2、js改造
image.png
修改上述js文件，添加如下代码：
/*---------------------流程设计器扩展用户与用户组--------------------*/
//参数初始化
$scope.gridData = [];//表格数据
$scope.gridDataName = 'gridData';
$scope.selectTitle = '选择代理人';
$scope.columnData = [];//表格列数据
$scope.columnDataName = 'columnData';
$scope.selectType = 0;//0-代理人，1-候选人，2-候选组
$scope.totalServerItems = 0;//表格总条数
//分页初始化
$scope.pagingOptions = {
pageSizes: [10, 20, 30],//page 行数可选值
pageSize: 10, //每页行数
currentPage: 1, //当前显示页数
};
//Grid 筛选
$scope.projects = [];
$scope.selectedProject = -1;
//异步请求项目列表数据
$scope.getProjectDataAsync = function(){
$http({
method: 'POST',
url: ACTIVITI.CONFIG.contextRoot+'/model/getProjectList'
}).then(function successCallback(response) {
$scope.projects = response.data;
if($scope.projects.length > 0){
$scope.selectedProject = $scope.projects[0].pkid;
}
$scope.dataWatch();
}, function errorCallback(response) {
// 请求失败执行代码
console.log("项目列表请求失败！");
});
}
$scope.getProjectDataAsync();
//数据监视
$scope.dataWatch = function (){
//分页数据监视
$scope.$watch('pagingOptions', function (newValue, oldValue) {
$scope.getPagedDataAsync($scope.pagingOptions.currentPage, $scope.pagingOptions.pageSize, $scope.selectedProject);
},true);
//当切换类型时，初始化当前页
$scope.$watch('selectType', function (newValue, oldValue) {
if(newValue != oldValue){
$scope.pagingOptions.currentPage = 1;
$scope.getPagedDataAsync($scope.pagingOptions.currentPage, $scope.pagingOptions.pageSize, $scope.selectedProject);
}
},true);
//切换平台
$scope.change = function(x){
$scope.selectedProject = x;
$scope.getPagedDataAsync($scope.pagingOptions.currentPage, $scope.pagingOptions.pageSize, $scope.selectedProject);
};
};
//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;
});
}
//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;
}
};
$scope.getGroupData = function(data){
var prefix = ['${projectId}_','${bankEnterpriseId}_','${coreEnterpriseId}_','${chainEnterpriseId}_'];
var result = prefix[data.enterpriseType] + data.roleCode;
return result;
};
//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 : '登录名',
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>'
}
];
//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----如果有此 contains 直接用最好
function array_contain(array, obj){
for (var i = 0; i < array.length; i++){
if (array[i].value == obj)//如果要求数据类型也一致，这里可使用恒等号===
return true;
}
return false;
}
其中，查询用户和角色列表的接口需要后端接口提供：
//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;
});
}
本文实现了先选项目，然后再加载用户和角色列表，因此代码中多出了这一部分，读者可根据需要决定是否去除：
//异步请求项目列表数据
$scope.getProjectDataAsync = function(){
$http({
method: 'POST',
url: ACTIVITI.CONFIG.contextRoot+'/model/getProjectList'
}).then(function successCallback(response) {
$scope.projects = response.data;
if($scope.projects.length > 0){
$scope.selectedProject = $scope.projects[0].pkid;
}
$scope.dataWatch();
}, function errorCallback(response) {
// 请求失败执行代码
console.log("项目列表请求失败！");
});
}
最终实现的效果是：
1）点击办理人输入框，右侧立即加载用户列表，支持分页，点击右侧某个用户，该用户的ID自动填入办理人输入框；
2）点击候选人输入框，右侧立即加载用户列表，支持分页，点击右侧某个用户，该用户的ID自动填入候选人输入框，可多次点击用户添加多个候选人；
3）点击候选组输入框，右侧加载角色列表，支持分页，点击某个角色，该角色编号自动填入候选组输入框，可多次点击角色添加多个候选组；

另外非常抱歉，由于最近换了工作，而公司不能连接外网，故有小伙伴的信息没有及时回复。主要代码都在文中了，私信要源码的小伙伴可以在文中直接复制下来，是一样的。
