Salesforce Apex开发笔记

获取记录类型

Id rid = [select Id from RecordType where DeveloperName = 'Campaign' and sobjecttype ='DocumentCompiling__c'][0].Id;

RecordType recoType =  [select Id from RecordType where SobjectType = 'DocumentCompiling' and DeveloperName = 'BidDocumentation' limit 1];

Id recordTypeId = Schema.SObjectType.对象API.getRecordTypeInfosByName().get('记录类型名').getRecordTypeId();

备注：不建议用ByName查询记录类型，因为记录类型的Name会根据系统语言进行变更。

Id recordTypeId = Schema.SObjectType.对象名.getRecordTypeInfosByDeveloperName().get('记录类型名称').getRecordTypeId();

根据ID获取记录类型名

Schema.getGlobalDescribe().get(objectName).getDescribe().getRecordTypeInfosById().get(strRecordTypeId).getName();

锁定记录

先开启配置

例子

List<Order_Details__c> orddList = [Select Id,OrderNo__r.Status, OrderNo__c fromOrder_Details__cwhere OrderNo__c in : ordId];
//将数据锁定 可以是对象的List集合，也可以是Id的Set
Approval.LockResult[] lrList = Approval.lock(orddList, false);
//将数据解锁
Approval.UnlockResult[] lrList = Approval.unlock(orddList, false);

判断记录是否锁定：

Approval.isLocked(记录Id);

获取旧对象

trigger.oldMap.get();

Apex Scheduler类启动方法

proschedule p = new proschedule();
String sch = '0 0 8 13 2 ?';//秒分时日月周年
system.schedule('One Time Pro', sch, p);

每小时运行一次

System.schedule('交际费预算每小时运行一次', '0 0 * * * ?', new Sch_Interface_B2B_ComBudget() );

Apex batch调用方法

无参数情况并立即启动：

Database.executeBatch(new UpdateAccountFields());

Database.executeBatch(new UpdateAccountFields(),'ID',数量);

在apex类中给页面给页面提示

原始页面报错：

对象.addError('');

自己定义的页面报错

ApexPages.addMessage(new ApexPages.Message(ApexPages.Severity.ERROR, '责任人字段必填'));

获取选项列表的值

List<String> listHaveAcquiredLsit = new List<String>();
        List<String> designInformationList = new List<String>();
        Integer i = 0;
        Schema.DescribeSObjectResult dsr = 对象名.sObjectType.getDescribe();
        Map<String, Schema.SObjectField> field_map = dsr.fields.getMap();
        List<Schema.PicklistEntry> HaveAcquiredValues = field_map.get('字段名').getDescribe().getPickListValues();
        List<Schema.PicklistEntry> DesignInfoValues = field_map.get('字段名').getDescribe().getPickListValues();
        for (Schema.PicklistEntry a : HaveAcquiredValues) {
            listHaveAcquiredLsit.add(a.getValue());
        }
        for (Schema.PicklistEntry a : DesignInfoValues) {
            designInformationList.add(a.getValue());
        }

public static Map<String,String> getPickList(String objectName,String fieldname){
        Map<String,String> picklistMap = new Map<String,String>();
        Schema.SObjectType targetType = Schema.getGlobalDescribe().get(objectName);//From the Object Api name retrieving the SObject
        Sobject Object_name = targetType.newSObject();
        Schema.sObjectType sobject_type = Object_name.getSObjectType(); //grab the sobject that was passed
        Schema.DescribeSObjectResult sobject_describe = sobject_type.getDescribe(); //describe the sobject
        Map<String, Schema.SObjectField> field_map = sobject_describe.fields.getMap(); //get a map of fields for the passed sobject
        List<Schema.PicklistEntry> pick_list_values = field_map.get(fieldname).getDescribe().getPickListValues(); //grab the list of picklist values for the passed field on the sobject
        for (Schema.PicklistEntry a : pick_list_values) { //for all values in the picklist list
          picklistMap.put(a.getValue(), a.getLabel());
       }
       return picklistMap;
    }

字符串

去空行

opp.Field4YZSQ__c = opp.Field4YZSQ__c.replaceAll('((\r\n)|\n)[\\s\t ]*(\\1)+', '$1').replaceAll('^((\r\n)|\n)', '');

替换

opp.Field4YZSQ__c = opp.Field4YZSQ__c.replaceAll(旧值,新值);

包含

contains

类型之间的转换

list转string

String s = String.join(集合名称,';')

string转list

str.split(';')

map转obj

Map<String,String> mapstr  = new Map<String,String>();
mapstr.put('Name', 'true');
mapstr.put('Id', 'eee');
String s = JSON.serialize(mapstr);
Account acc = (Account)JSON.deserialize(s, Account.class);
System.debug(acc);

Object 转 Map

 Map<String, Object> tempMap = (Map<String, Object>)JSON.deserializeUntyped(JSON.serialize(Object));

审批

SF中，与审批有关的对象：
ProcessInstance
关联了记录
ProcessInstanceHistory
PorcessInstanceHistory
被分配人 =======> OriginalActorId
实际批准人 =======> ActorId
审批日期 =======> SystemModstamp
审批状态 =======> StepStatus
审批整体状态 =======> 与之相对应的ProcessInstance上的Status
审批留言 =======> Comments
审批目标对象 =======> TargetObjectId
Approval Status:(ProcessInstance:Status, ProcessInstanceHistory:StepStatus)
中文名 API Name Label
已批准 =====>Approved =====> Approved
故障 =====>Fault =====> Fault
暂停 =====>Held =====> Hold
无响应 =====>NoResponse =====> NoResponse
待处理 =====>Pending => Pending
已重新分配=>Reassigned =====> Reassigned
已拒绝 =====>Rejected =====> Rejected
已调回 =====>Removed =====> Recalled

通过/拒绝某个节点的审批

//Class used for Approving Record
 Approval.ProcessWorkitemRequest req = new Approval.ProcessWorkitemRequest();
 req.setComments('Approving request for Opportunity');
 
 //Approve or Reject Record
 req.setAction('Approve');//设置状态为批注还是拒绝 Reject
 
 //Getting Work Item Id
 ProcessInstanceWorkitem pItem = [Select Id from ProcessInstanceWorkitem 
 where ProcessInstance.TargetObjectId =: opp.id];

 req.setWorkitemId(pItem.Id);
 // Submit the request for approval
 Approval.ProcessResult result = Approval.process(req);

自动提起审批流
单个提交审批

 Approval.ProcessSubmitRequest req1 = new Approval.ProcessSubmitRequest();
    req1.setComments('新供应商注册信息已提交，请审核！');
    req1.setObjectId(需要审批的记录的Id);
    req1.setSubmitterId(初始提交人Id);
    req1.setProcessDefinitionNameOrId('批准进程api Name');
   // req1.setNextApproverIds(approverIdList);// 下一步审批人，传入参数必须为List，注意是队列类型小组Id，而不是用户Id 
   // req1.setSkipEntryCriteria(true);// 是否跳过标准
    Approval.ProcessResult result = Approval.process(req1);

批量提交审批

List<Approval.ProcessSubmitRequest> requests = new List<Approval.ProcessSubmitRequest>();
	For(对象){
		Approval.ProcessSubmitRequest req1 = new Approval.ProcessSubmitRequest();
	        req1.setComments('新供应商注册信息已提交，请审核！');
	        req1.setObjectId(需要审批的记录的Id);
	        req1.setSubmitterId(初始提交人Id);
	        req1.setProcessDefinitionNameOrId('批准进程api Name');
	       // req1.setNextApproverIds(approverIdList);// 下一步审批人，传入参数必须为List，注意是队列类型小组Id，而不是用户Id 
	       // req1.setSkipEntryCriteria(true);// 是否跳过标准
		requests.add(req1); 
		
	}
	 Approval.ProcessResult[] processResults = Approval.process(requests);

获取字段的标签、API、选项列表的值

获取所有字段

SObjectType esalesTemp = Schema.getGlobalDescribe().get('表名称');
Map<String,Schema.SObjectField> mfields = esalesTemp.getDescribe().fields.getMap();

for (String s: mfields.keySet()) {
    SObjectField fieldToken = mfields.get(s);
          DescribeFieldResult selectedField = fieldToken.getDescribe();
          System.debug('===Name=='+selectedField.getName()); //API名称
          System.debug('===Label=='+selectedField.getLabel());  //字段标签
          System.debug('===Type=='+selectedField.getType());//数据类型
          Boolean isRequired = false;
          if (selectedField.isNillable() == false) {
            isRequired = true;
          }else{
            isRequired = false;
          }
          System.debug('===isRequired=='+isRequired);
}

获取特定的选项列表字段:

    List<String> result = new List<String>();
        Schema.DescribeFieldResult fieldResult = 表名称.字段API.getDescribe();
        List<Schema.PicklistEntry> ple = fieldResult.getPicklistValues();
        for( Schema.PicklistEntry f : ple)
        {
            result.add(f.getLabel());
        }       

表名称.字段API.getDescribe().getLabel()

// 获取全部字段

List fields = new List(AgreementPayment__c.SObjectType.getDescribe().fields.getMap().keySet());
Set  set_agmeId = new Set();
set_agmeId.addAll(map_agid_queidset.keySet());
String appaSql = 'select ' + String.join(fields, ',') + ' from AgreementPayment__c where Agreement__c in: set_agmeId';

获取Map集合的第一个值

Map<Decimal,Decimal> maps = new Map<Decimal,Decimal>();
maps.put(1, 2);
maps.put(2, 7);
maps.put(5, 9);
System.debug(maps.keySet().iterator().next());
System.debug(maps.values().iterator().next());

获取salesforce的链接

基础链接：

Url.getSalesforceBaseUrl().toExternalForm()

完全链接：

ApexPages.currentPage().getURL()

获取当前登录用户的id

UserInfo.getId();

通过Id获取对象

某个ID.getsobjecttype().getDescribe()
Id.valueOf('a0G0p0000005bVT').getsobjecttype().getDescribe().getName()

后台发送邮件

无邮件模板

Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();
String[] toAddresses = new String[] {UserInfo.getUserEmail()};
mail.setToAddresses(toAddresses);        
mail.setSenderDisplayName('销售目标');
mail.setSubject('主题');
mail.setHtmlBody( '内容' );
Messaging.sendEmail(new Messaging.SingleEmailMessage[] {mail});

有邮件模板

List<Messaging.SingleEmailMessage> emails  = new List<Messaging.SingleEmailMessage>();
Messaging.SingleEmailMessage temail = new Messaging.SingleEmailMessage();
temail.setSenderDisplayName('主题');
temail.setWhatId(邮件需要的对象Id);
temail.setTargetObjectId(联系人Id);
temail.setTreatTargetObjectAsRecipient(false);
temail.setTemplateId(邮件模板Id);
temail.setSaveAsActivity(false);
temail.setToAddresses(addresses);
emails.add(temail);
Messaging.sendEmail(emails);

如果需要的对象为潜客则

temail.setWhatId(邮件需要的对象Id); 不需要了
temail.setTargetObjectId(联系人Id);修改为 temail.setTargetObjectId(潜客ID);

通过url下载附件保存到salesforce

// Instantiate a new http object
Http h = new Http();
// Instantiate a new HTTP request, specify the method (GET) as well as the endpoint
HttpRequest req = new HttpRequest();
req.setEndpoint('YOUR_URL');
req.setTimeout(60000);//sets maximum timeout
req.setMethod('GET');
// Send the request, and return a response
HttpResponse res = h.send(req);
Blob body = res.getBodyAsBlob();
//then you can attach this body wherever you want
Attachment att = new Attachment(Name = 'SET A NAME', Body = body, ContentType = 'SET A VALID CONTENT TYPE', ParentId='PARENT_OBJ_ID');
insert att;

Add a static boolean variable to a class, and check its value within the affected triggers.

public class HelperClass { public static boolean firstRun = true; }



trigger affectedTrigger on Account (before delete, after delete, after undelete) 
{ 
	if(Trigger.isBefore)
	{       
		if(Trigger.isDelete)
		{            
			if(HelperClass.firstRun)

				Trigger.old[0].addError('Before Account Delete Error');                
				HelperClass.firstRun=false;

根据列表视图获取数据

Yes you can!

First get the sObjectType of the ListView by querying like

SELECT Id, sObjectType FROM ListView WHERE Id = :yourId

Then simply make a callout to your own org with a URL like

/services/data/v40.0/sobjects/[sObjectType]/listviews/[yourId]/describe

You will get back an object with (amongst others) a query attribute. Use that to query your records.

Making a callout to your own org has become even easier since spring 19 because you don’t need a Remote Site Setting and can use UserInfo.getSessionId() even in async jobs.

Good luck!

客户中标准生日字段
查询今天的数据是如果用 = today 或 yesterday 时只匹配月份和日期，不匹配年份

TimeZone tz = UserInfo.getTimeZone();
DateTime dt = Datetime.now();
system.debug('gmt时间 ' + dt);
system.debug('正确时间' + dt.format());
system.debug('Offset ' + tz.getOffset(dt)/1000);
system.debug('Formatted Time ' + dt.addSeconds((tz.getOffset(dt)/1000)));

sql的分组查询

使用 GROUP BY 进行分组，并且搜索出来的字段仅能是Id和用于分组的字段。


List<AggregateResult> agrResult = new List<AggregateResult>([SELECT Status FROM Case GROUP BY Status]);//

注意点：不能超过2000条数据，limit 2000

数字格式化成货币格式

Decimal rA = 1298763.86;
Integer ra2 = Integer.valueOf(rA);
List<String> args = new String[]{'0','number','###,###,##0.00'};
String s = String.format(ra2.format(), args);
System.debug(s);

获取富文本区域的图片链接

Account record = [select Id,textlong__c from Account where id = '0010K00002I3aCI'];
// use reluctant regex to match each image tag individually
// https://docs.oracle.com/javase/tutorial/essential/regex/quant.html
Matcher imgMatcher = Pattern.compile( '<img(.+?)>' ).matcher( record.textlong__c );

// iterate each image tag found
while ( imgMatcher.find() ) {

    // get the image tag html
    String imageTag = imgMatcher.group();
    System.debug( 'imageTag=' + imageTag );

    // get the value of the src attribute
    // the leading space is significant to avoid other attributes like data-cke-saved-src
    String imageURL = imageTag.substringBetween( ' src="', '"' );
    System.debug( 'imageURL=' + imageURL );

    // if url contained parameters they might be html escaped, unescape them
    // or, more conservatively, replace '&' with '&'
    String decodedURL = imageURL.unescapeHtml4();
    System.debug( 'decodedURL=' + decodedURL );

    // note, as of API 34.0 or later, getContent() is considered an http callout
    // so take that into consideration for your unit tests and governor limits
    // https://developer.salesforce.com/docs/atlas.en-us.pages.meta/pages/apex_System_PageReference_getContent.htm
    PageReference page = new PageReference( decodedURL );
    Blob b = page.getContent();
    System.debug( 'blob=' + b );

    System.debug( 'Enjoy your Blob, save it as a Document, ContentVersion, whatever!' );

    System.debug(''); // I like blank lines in my logs, easier to scan/read =)

计算工作日

Date selectedDate =  Date.today();
Date lastDate = selectedDate.toStartOfMonth().addDays(Date.daysInMonth(selectedDate.year(), selectedDate.month()) - 1);
System.debug(lastDate);
BusinessHours bh = [SELECT Id FROM BusinessHours WHERE IsDefault=true];
System.debug(BusinessHours.isWithin(bh.id, lastDate));

BusinessHours.isWithin(bh.id, lastDate) 如果这一天是工作日，那么则返回true，如果不是，则返回false

需先在系统设置标准的工作时间

获取倒数第二个工作日

Date selectedDate =  Date.today();
Date lastDate = selectedDate.toStartOfMonth().addDays(Date.daysInMonth(selectedDate.year(), selectedDate.month()) - 1);
System.debug(lastDate);
BusinessHours bh = [SELECT Id FROM BusinessHours WHERE IsDefault=true];
System.debug(BusinessHours.isWithin(bh.id, lastDate));
Integer i = 0;
Date last2day;
while (i < 2)
{
    if (BusinessHours.isWithin(bh.id, lastDate)) 
    {
        i++;
    }
    last2day = lastDate;
    lastDate = lastDate.addDays(-1);
}
System.debug(last2day);
