工作始终会遇到很多需要收集的资料，时间长了，难免会忘记。作个简要记录，以资后用....
1. EJB容器下面使用JPA处理大批量数据，最终还是直接使用JDBC来做底层处理，容器处理事务，
不需要对事务做单独处理。
public void importData(final List<TimetableJourneyDetail> retList) {
if (null != retList && retList.size() > 0) {
final EntityManagerFactory emf = entityManager.getEntityManagerFactory();
final BrokerFactory factory = JPAFacadeHelper.toBrokerFactory(emf);
final OpenJPAConfiguration conf = factory.getConfiguration();
final DataSourceWrapper dw = new DataSourceWrapper((DataSource) conf.getConnectionFactory());
final SystemUser user = SecurityUtil.getCurrentUser();
final Long userId = user.getId();
final String loginId = user.getLoginId();
PreparedStatement pst = null;
Connection conn = null;
try {
conn = dw.getConnection();
//conn.setAutoCommit(false);
final StringBuffer sql = new StringBuffer("INSERT INTO \"LR_TIMETABLE_JOURNEY_DETAIL\"");
sql.append("(\"ID\",\"PARENT_ID\",\"LINE_NAME\",\"TRAIN_NO\",\"TRS_NO\",")
.append("\"TRIP_NO\",\"REVENUE_FLAG\",\"DIRECTION\",\"FROM_STOP_PLATFORM\",")
.append("\"FROM_STOP_ARRIVAL_TIME\",\"FROM_STOP_DEPART_TIME\",\"TO_STOP_PLATFORM\"")
.append(",\"TO_STOP_ARRIVAL_TIME\",\"TO_STOP_DEPART_TIME\",\"DEPART_IN_OUT_INDICATOR\"")
.append(",\"SINGLE_COUPLE_CAR\",\"KM\",\"TRIPS\",\"LAST_UPD_USER_ID\",")
.append("\"LAST_UPD_USER\",\"LAST_UPD_DATETIME\") VALUES")
.append("(SEQ_JOURNEY_DETAIL.NEXTVAL,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,")
.append(userId).append(",'").append(loginId).append("',(CURRENT DATE))");
pst = conn.prepareStatement(sql.toString());
for (TimetableJourneyDetail d : retList) {
pst.setLong(1, d.getParentId());
pst.setString(2, d.getLineName());
pst.setString(3, d.getTrainNo());
pst.setString(4, d.getTrsNo());
pst.setString(5, d.getTripNo());
pst.setString(6, d.getRevenueFlag());
pst.setString(7, d.getDirection());
pst.setString(8, d.getFromStopPlatform());
pst.setString(9, d.getFromStopArrivalTime());
pst.setString(10, d.getFromStopDepartTime());
pst.setString(11, d.getToStopPlatform());
pst.setString(12, d.getToStopArrivalTime());
pst.setString(13, d.getToStopDepartTime());
pst.setString(14, d.getDepartInOutIndicator());
pst.setString(15, d.getSingleCoupleCar());
pst.setDouble(16, d.getKm());
pst.setDouble(17, d.getTrips());
pst.addBatch();
}
final int []count = pst.executeBatch();
System.out.println("number : " + count.length);
//conn.commit();
conn.close();
} catch (SQLException e) {
e.printStackTrace();
} finally {
if (null != pst) {
try {
pst.close();
if (null != conn && !conn.isClosed()) {
conn.close();
}
} catch (SQLException e) {
e.printStackTrace();
}
}
}
}
}
2. 利用Java异常特性来校验日期格式，代码简洁，不错的功能...
/**
* To check the date is valid or not
* @param input
* @return
*/
public static boolean isValidDate(final String input) {
boolean isValid = false;
final String formatString = "yyyy-MM-dd";
try {
final SimpleDateFormat format = new SimpleDateFormat(formatString);
format.setLenient(false);
format.parse(input);
isValid = true;
} catch (ParseException e) {
isValid = false;
} catch (IllegalArgumentException e) {
isValid = false;
}
return isValid;
}
3. Java操作内存溢出几个案例...
/**
*
* outOfmemory
* @param a
* @param b
* @return the void
*/
private static void outOfmemory(int a , int b) {
//java.lang.StackOverflowError outOfmemory
// outOfmemory(a*b, b);
//java.lang.OutOfMemoryError: Java heap space
List<String> str = new ArrayList<String>(0);
int ab = 0;
while(true) {
//ab++;
str.add("abc");
//Object obk = new Object();
}
//java.lang.OutOfMemoryError: PermGen space
// List<String> str = new ArrayList<String>(0);
// int i = 0;
// while(true) {
// i++;
// str.add(String.valueOf(i).intern());
// }
}
4. 四舍五入处理方法...
/**
*
* jsfRound
* @param a
* @return the void
*/
private static void jsfRound(double a) {
System.out.println("==0==" + a + "==" + String.format("%.2f", a));
//please attention ROUND_HALF_DOWN ROUND_HALF_UP
System.out.println("==1==" + a + "===" + new BigDecimal(String.valueOf(a)).setScale(2, BigDecimal.ROUND_HALF_DOWN).doubleValue());
System.out.println("==2==" + a + "==" + new BigDecimal(String.valueOf(a)).setScale(2, BigDecimal.ROUND_HALF_UP).doubleValue());
}
5. 处理集合中重复数据....
/**
*
* dealWithDuplicationObjArray
* @return
* @return the List<Object[]>
*/
private static List<Object[]> dealWithDuplicationObjArray() {
final List<Object[]> listObj = new ArrayList<Object[]>(0);
listObj.add(new Object[]{"20/10/2012","a","1 REV 4"});
listObj.add(new Object[]{"21/10/2012","b","1 REV 4"});
listObj.add(new Object[]{"22/10/2012","c","1 REV 4"});
listObj.add(new Object[]{"23/10/2012","d","1 REV 4"});
listObj.add(new Object[]{"23/10/2012","666","1 REV 3"});
final List<Object[]> retList = new ArrayList<Object[]>(0);
final Map<Object, Object[]> map = new HashMap<Object, Object[]>();
for (Object[] objects : listObj) {
map.put(objects[0], objects);
}
final Set<Entry<Object, Object[]>> set = map.entrySet();
for (Entry<Object, Object[]> entry : set) {
retList.add(entry.getValue());
System.out.println("key = " + entry.getKey() + "=value=" + ((Object[])entry.getValue())[1] + "---" + ((Object[])entry.getValue())[2]);
}
return retList;
}
处理重复集合元素另一方法，从已有集合元素中找出重复的元素：
/**
* Find Collection duplicated elements,get duplicated elements
* @param elements
* @return Collection
*/
public static Collection<?> findCollectionDuplicateElements(final Collection<?> elements) {
final Set<Object> set = new HashSet<Object>();
final Set<Object> retSet = new HashSet<Object>();
for (Object object : elements) {
set.add(object);
}
if (elements.size() == set.size()) {
return retSet;
} else {
for (Object object : set) {
elements.remove(object);
}
}
for (Object object : elements) {
retSet.add(object);
}
return retSet;
}
6. 反射找出javabean对象属性名以及对应值：
/**
*
* copyObjectToHashMap
* @param object
* @return
* @throws Exception
* @return the Map<?,?>
*/
public static Map<?,?> copyObjectToHashMap(final Object object) throws Exception {
final Class clazz = object.getClass();
final Method[] methods = clazz.getDeclaredMethods();
final Map<String, Object> vo = new HashMap<String, Object>();
for (Method method : methods) {
String methodName = method.getName();
String tempName = "";
if (methodName.startsWith("get")) {
tempName = methodName.substring(3, 4).toLowerCase() + methodName.substring(4);
final Object obj = method.invoke(object, (Object[]) method.getParameterTypes());
if (null != obj && !"".equals(obj)) {
vo.put(tempName, obj);
}
}
tempName = null;
methodName = null;
}
return vo;
}
7. 对于大数值的运算公式(任意整数使用BigInteger类，对于任意浮点数使用BigDecimal类)
private static final int DEF_DIV_SCALE = 10;
public static BigDecimal add(BigDecimal v1, BigDecimal v2) {
return v1.add(v2);
}
public static BigDecimal subtract(BigDecimal v1, BigDecimal v2) {
return v1.subtract(v2);
}
public static BigDecimal multiply(BigDecimal v1, BigDecimal v2) {
return v1.multiply(v2);
}
public static BigDecimal div(BigDecimal v1, BigDecimal v2) {
return div(v1, v2, DEF_DIV_SCALE);
}
public static BigDecimal div(BigDecimal v1, BigDecimal v2, int scale) {
if (scale < 0) {
throw new IllegalArgumentException("The scale must be a positive integer or zero");
}
return v1.divide(v2, scale, BigDecimal.ROUND_HALF_UP);
}
public static double round(double v, int scale) {
if (scale < 0) {
throw new IllegalArgumentException("The scale must be a positive integer or zero");
}
BigDecimal b = new BigDecimal(Double.toString(v));
BigDecimal one = new BigDecimal("1");
return b.divide(one, scale, BigDecimal.ROUND_HALF_UP).doubleValue();
}
public static void main(String[] args) {
BigDecimal a = new BigDecimal("123456789123");
BigDecimal b = new BigDecimal("987654321987");
System.out.println(add(a, b));
System.out.println(subtract(a, b));
System.out.println(div(a, b));
System.out.println(multiply(a, b));
}
8. 深度克隆方法(推荐数据流方法，或者自己重写必须要写最小的基本数据类型为止(难度大))
//深度克隆, 克隆对象必须实现 java.io.Serializable
public final static Object objectCopy(Object oldObj) {
Object newObj = null;
ByteArrayOutputStream bo = null;
ObjectOutputStream oo = null;
ByteArrayInputStream bi = null;
ObjectInputStream oi = null;
try {
bo = new ByteArrayOutputStream();
oo = new ObjectOutputStream(bo);
oo.writeObject(oldObj);//源对象
bi = new ByteArrayInputStream(bo.toByteArray());
oi = new ObjectInputStream(bi);
newObj = oi.readObject();//目标对象
} catch (IOException e) {
e.printStackTrace();
} catch (ClassNotFoundException e) {
e.printStackTrace();
} finally {
try {
bo.close();
oo.close();
bi.close();
bo.close();
} catch (IOException e) {
e.printStackTrace();
}
}
return newObj;
}
9，图形化校验一例
三种方式输出：流文件直接输出、base64(有些浏览器存在问题)、保存文件路径方式
后端
private static class GenerateVerifyPicture {
private static char pictureChars[] = { 'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i',
'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v',

'9', '0' };
public static String getCertPic(int width, int height, OutputStream os) {
if (width <= 0)
width = 60;
if (height <= 0)
