Apache Commons 常用工具类整理

其实一直都在使用常用工具类，只是从没去整理过，今天空了把一些常用的整理一下吧
怎么使用的一看就明白，另外还有注释，最后的使用pom引入的jar包

public class ApacheCommonsTest {

    
    @Test
    public void testCopyNewBean() throws Exception {
 StuForm form = new StuForm("lee", 18, 1, new Date(), true);
 Stu stu = new Stu(); 
 BeanUtils.copyProperties(form, stu);
 System.out.println(stu.toString());

    }

    
    @Test
    public void testbase64Code() throws Exception {    
 String name1 = "hello, my name is lee~";
 System.out.println("Before: " + name1);

 String name2 = base64.encodebase64String(name1.getBytes());
 System.out.println("After encode: " + name2);

 String name3 = new String(base64.decodebase64(name2));
 System.out.println("After decode: " + name3);

 String url1 = "www.lee.com.cn";
 System.out.println("URL Before: " + url1);

 String url2 = base64.encodebase64URLSafeString(url1.getBytes());
 System.out.println("URL After decode: " + url2);

 String url3 = new String(base64.decodebase64(url2));
 System.out.println("URL After decode: " + url3);
    }

    
    @Test
    public void testCollection() throws Exception {
 OrderedMap om = new linkedMap();
 om.put("one", 1);
 om.put("two", "2");
 om.put("three", "three");
 om.put("fore", 4);
 om.put("five", "5");
 System.out.println(om.firstKey());
 System.out.println(om.nextKey("fore"));
 System.out.println(om.previousKey("five"));

 System.out.println("==============================");

 BidiMap bm = new TreeBidiMap();
 bm.put("three", "3");
 bm.put("five", "isfive");
 System.out.println(bm.getKey("isfive").toString());
 System.out.println(bm.get("three"));

 // 交换key和value
 BidiMap newMap = bm.inverseBidiMap();
 System.out.println(newMap.size());

 System.out.println("==============================");
