一、考勤界面
二、分析
1)同步数据首先要得到数据,如何得到数据呢?
第一步:创建签卡数据的触发器
第二步:创建同步日志类,把所有的签卡信息都添加到同步日志里
2)从数据源得到数据后以Json格式传递
3)创建一个SpringMVC的Maven工程,
a、以阿里巴巴的Druid配置数据源,
b、创建个定时器,每隔一分钟从Salesforce的日志里读取信息
c、在Dao层里写数据同步的代码
d、测试
三、同步示意图:
四、触发器代码:
trigger attendanceSyncTrigger on attendance__c (after insert) {
//查询类型
List<RecordType> rtList = [SELECT Id, Name, DeveloperName, SobjectType FROM RecordType WHERE SobjectType=‘attendance__c‘];
Map<String,String> recordMap = new Map<String,String>();
for(RecordType r:rtList){
recordMap.put(r.Name,r.Id);
}
attendance__c order = Trigger.new[0];
//如果是插入状态,判断是不是“考勤“
if(Trigger.isInsert && recordMap.get(‘考勤管理‘).equals(order.RecordTypeId)){
if(order != null){
String projson = json.serialize(order);
system.debug(‘jjjjjjj:‘+projson);
//创建日志
SynLog__c syn = new SynLog__c();
syn.Name=String.valueOf(order.Id).subString(0,15);
//把数据赋给日志参数
syn.parameter__c = projson;
syn.ObjectName__c = ‘attendance__c‘;
syn.Operation__c = ‘Insert‘;
syn.Flag__c =‘No‘;
insert syn;
}
}
}
日志类:
五、SpringMVC的Maven工程
1)架构图:
2)pom.xml文件

</property>
</bean>
</beans>
6)实体类配置
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"

<bean id="appUtil" class="com.dzjg.common.AppUtil"/>
<context:component-scan base-package="com.dzjg.TimedTask"/>

7)从Salesforce读取信息
public class SyncLogDao {
/**
* 查询salesforce同步日志
*
* @return
*/
public static List<SynLog__c> getSynLogList() {
String soql = "select parameter__c,errorMsg__c,Flag__c,ObjectName__c,Operation__c,id from SynLog__c where Flag__c = ‘No‘";
try {
return (List<SynLog__c>) SFDaoUtils.queryListBySql(soql);
} catch (ConnectionException e) {
throw new RuntimeException(e);
}
}
/**
* 回写成功日志
*
* @param id
*/
public static void markFinishedById(String id) {
try {
SynLog__c synLog = new SynLog__c();
synLog.setId(id);
//设置处理时间
Date date = new Date();
Calendar cal = Calendar.getInstance();
cal.setTime(date);
synLog.setCompleteDate__c(cal);
synLog.setFlag__c("Yes");
SFDaoUtils.updateSObject(synLog);
} catch (Exception e) {
throw new RuntimeException(e);
}
}
/**
* 回写失败信息
* @param id
* @param errorMsg
*/
public static void markErrorMsgById(String id, String errorMsg) {
try {
SynLog__c a = new SynLog__c();
a.setId(id);
a.setErrorMsg__c(errorMsg);
//设置处理时间
Date date = new Date();
Calendar cal = Calendar.getInstance();
cal.setTime(date);
a.setCompleteDate__c(cal);
a.setFlag__c("Error");
SFDaoUtils.updateSObject(a);
} catch (Exception e) {
throw new RuntimeException(e);
}
}
}
8)把数据写入到数据库
/**
* salesforce 同步到中控考勤系统
*
* @Project dzjg
* @Package com.dzjg.TimedTask
* @author chenlin
* @version 1.0
* @Date 2016年5月16日
*/
@Service
public class SfToZKScheduler {
/**
* 记录日志文件
*/
private Logger log = LoggerFactory.getLogger(SfToZKScheduler.class);
/**
* 在app-scheduling.xml里<property name="targetMethod" value="sync" />调用,进行定时扫描
*/
public void sync() {
List<SynLog__c> synLogList = SyncLogDao.getSynLogList();
for (SynLog__c synLog : synLogList) {
handleItem(synLog);
}
}
public void handleItem(final SynLog__c synLog) {
try {
if(synLog == null){
return;
}
if (LogDao.isExit(synLog.getId())) {
SyncLogDao.markFinishedById(synLog.getId());// 回写成功日志
return;
}
if ("attendance__c".equalsIgnoreCase(synLog.getObjectName__c())) {
log.info("同步用户名称,id,签卡时间,签卡类型到中控考勤系统:" + synLog.getParameter__c());
final Attendance__c order = JSON.parseObject(synLog.getParameter__c(), Attendance__c.class);
ERPDao.commit(new VoidWrapper() {
public void doWork() {
if (order != null) {
try {
System.out.println("order == "+ order);
ERPDao.saveAttendenc(order);
log.info("考勤数据到中控:SUCCESS!!!");
} catch (Exception e) {
e.printStackTrace();
log.info("考勤数据到中控:ERROR!!!");
}
}
SyncLogDao.markFinishedById(synLog.getId());// 回写成功日志
LogDao.insertLog(synLog);
}
});
}
} catch (Exception e) {
log.error(ExceptionUtils.getStackTrace(e));
SyncLogDao.markErrorMsgById(synLog.getId(), e.getMessage());// 回写错误日志
}
}
}
9)数据层处理
public static void saveAttendenc(final Attendance__c order) {
if (order == null) {
return;
}
String uid = order.getAttend_userid__c();
if (TextUtil.isEmpty(uid)) {
return;
}
String userSql = "select userid from userinfo where badgenumber = ? ";
List<String> list = zkJdbcTemplate.queryForList(userSql, new Object[] { uid.trim() }, String.class);
if (list == null || list.size() <= 0) {
return;
}
final String userid = list.get(0).toString();
if (!TextUtil.isEmpty(userid) && TextUtil.isNum(userid)) {
String sql = "insert into checkexact "
+ " (change_time, create_operator, create_time, UserID, CHECKTIME, YUYIN , audit_status, CHECKTYPE, status, ISMODIFY, ISDELETE, INCOUNT, ISCOUNT) "
+ " values (?, ?, ?, ?, ?, ?, 2, ‘l‘, 0, 0, 0, 0, 0)";
zkJdbcTemplate.update(sql, new PreparedStatementSetter() {
@Override
public void setValues(PreparedStatement ps) throws SQLException {
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
ps.setString(1, sdf.format(new Date()));
ps.setString(2, order.getAttend_name__c());
ps.setString(3, sdf.format(new Date()));
ps.setInt(4, Integer.parseInt(userid));
// 添加异常打卡时间
ps.setString(5, order.getAttend_time__c());
ps.setString(6, order.getAttend_type__c());
}
});
}
}
10)获取Spring 的jdbcTemplate工具类
public class AppUtil implements ApplicationContextAware {
private static ApplicationContext appCtx;
/**
* 此方法可以把ApplicationContext对象inject到当前类中作为一个静态成员变量。
*
* @param applicationContext ApplicationContext 对象
* @throws org.springframework.beans.BeansException
*/
public void setApplicationContext(ApplicationContext applicationContext)
throws BeansException {
appCtx = applicationContext;
}
/**
* 这是一个便利的方法,帮助我们快速得到一个BEAN
*
* @param beanName bean的名字
* @return 返回一个bean对象
*/
public static <T> T getBean(String beanName) {
checkApplicationContext(appCtx);
return (T) appCtx.getBean(beanName);
}
/**
* 用于方便单元测试
* @param applicationContext
*/
private static void checkApplicationContext(ApplicationContext applicationContext) {
if (appCtx == null) {
synchronized (AppUtil.class) {
if (applicationContext == null) {
appCtx = new ClassPathXmlApplicationContext("spring/app-context.xml","spring/app-dao.xml","spring/app-action.xml");
}
}
}
}
}
