1-----创建javabean 代码如下
1 package BeanUtils; 2 import java.util.Date; 3 public class Admin { 4 private String userName; 5 private String age; 6 private Date birth; 7 public String getUserName() { 8 return userName; 9 } 10 public void setUserName(String userName) { 11 this.userName = userName; 12 } 13 public String getAge() { 14 return age; 15 } 16 public void setAge(String age) { 17 this.age = age; 18 } 19 20 public Date getBirth() { 21 return birth; 22 } 23 public void setBirth(Date birth) { 24 this.birth = birth; 25 } 26 @Override 27 public String toString() { 28 return "Admin [userName=" + userName + ", age=" + age + ", birth=" + birth + "]"; 29 } 30 }
2------java代码测试
1 @Test 2 public void test2(){ 3 String userName = "Jack"; 4 String age = "25"; 5 String birth = "1995-08-08"; 6 Admin admin = new Admin(); 7 //注册日期类型转换 8 ConvertUtils.register(new Converter() { 9 @Override 10 public Object convert(Class type, Object value) { 11 //判断 12 if(type != Date.class){ 13 return null; 14 } 15 if(value == null || "".equals(value.toString().trim())){ 16 return null; 17 } 18 SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd"); 19 try { 20 return dateFormat.parse(value.toString()); 21 } catch (Exception e) { 22 e.printStackTrace(); 23 throw new RuntimeException(e); 24 } 25 } 26 }, Date.class); 27 // 把表单提交的数据,封装到对象中 28 try { 29 BeanUtils.copyProperty(admin, "userName", userName); 30 BeanUtils.copyProperty(admin, "age", age); 31 BeanUtils.copyProperty(admin, "birth", birth); 32 } catch (Exception e) { 33 // TODO Auto-generated catch block 34 e.printStackTrace(); 35 throw new RuntimeException(e); 36 } 37 System.err.println(admin); 38 } 39 40 //2. 使用提供的日期类型转换器工具类 41 @Test 42 public void test3() throws Exception { 43 // 模拟表单数据 44 String name = "jack"; 45 String age = "20"; 46 String birth = "1998-08-25"; 47 // 对象 48 Admin admin = new Admin(); 49 // 注册日期类型转换器:2, 使用组件提供的转换器工具类 50 ConvertUtils.register(new DateLocaleConverter(), Date.class); 51 // 把表单提交的数据,封装到对象中 52 BeanUtils.copyProperty(admin, "userName", name); 53 BeanUtils.copyProperty(admin, "age", age); 54 BeanUtils.copyProperty(admin, "birth", birth); 55 //------ 测试------ 56 System.out.println(admin); 57 }
--------测试结果
