Commons BeanUtils的基本用法
//1.Commons beanutils要用到的三个包，一个主要包commons-beanutils-1.8.0.jar和两个依赖包commons-logging-1.1.1.jar和commons-logging-api-1.1.1.jar
public class BeanUtilsExample {
public static void main(String[] args) throws IllegalAccessException, InvocationTargetException, NoSuchMethodException {
Profile profile = new Profile();
Map<String,String> map = new HashMap<String,String>();
map.put("home", "123");
map.put("tel", "12574");
profile.setPhone(map);
profile.setBrithDate(new Date());
profile.setEmail("[email protected]");
Address[] address = {new Address("pzh","xj"),new Address("km","rmdl")};
profile.setAddress(address);
User user = new User();
user.setId(100);
user.setUsername("username");
user.setPassword("password");
user.setProfile(profile);
//一般类型
prt(BeanUtils.getProperty(user, "id"));
//引用类型的一般类型
prt(BeanUtils.getProperty(user, "profile.brithDate"));
//Map类型
prt(BeanUtils.getProperty(user, "profile.phone(home)"));
//数组和List，Set类型
prt(BeanUtils.getProperty(user, "profile.address[0].city"));
User user2 = new User();
//复制Bean，但如果Bean里面引用类型的不能复制
BeanUtils.copyProperties(user2, user);
}
public static void prt(Object object){
System.out.println(object);
}
}
JavaBean
public class Address implements Serializable {
private String city;
private String addr;
public Address(){
}
public Address(String city,String addr){
this.city = city;
this.addr = addr;
}
public String getCity() {
return city;
}
public void setCity(String city) {
this.city = city;
}
public String getAddr() {
return addr;
}
public void setAddr(String addr) {
this.addr = addr;
}
}
public class Profile implements Serializable {
private Map<String,String> phone;
private Address[] address;
private Date brithDate;
private String email;
public Map<String, String> getPhone() {
return phone;
}
public void setPhone(Map<String, String> phone) {
this.phone = phone;
}
public Address[] getAddress() {
return address;
}
public void setAddress(Address[] address) {
this.address = address;
}
public Date getBrithDate() {
return brithDate;
}
public void setBrithDate(Date brithDate) {
this.brithDate = brithDate;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
}
public class User implements Serializable {
private int id;
private String username;
private String password;
private Profile profile;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public Profile getProfile() {
return profile;
}
public void setProfile(Profile profile) {
this.profile = profile;
}
}
//LazyDynaBeanExample的用法，动态的创建JAVABEAN
public class LazyDynaBeanExample {
public static void main(String[] args) {
LazyDynaBean user = new LazyDynaBean();
LazyDynaBean profile = new LazyDynaBean();
//设置一般属性
user.set("userId", 123456);
//设置对象
user.set("profile", profile);
//设置对象的数组，List
profile.set("address", 0, "a");
//设置对象的Map
profile.set("tel","key", "value");
}
}
//BeanUitls还封装了对JDBC连结结果集ResultSet
//ResultSetDynaClass和RowSetDynaClass
