SpringMVC——POJO对象绑定请求参数

使用POJO对象绑定请求参数值

public class User {
private String username;
private String password;
private String email;
private int age;
private Address address;

public Address getAddress() {
return address;
}
public void setAddress(Address address) {
this.address = address;
}
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 String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
@Override
public String toString() {
return "User [username=" + username + ", password=" + password + ", email=" + email + ", age=" + age
+ ", address=" + address + "]";
}

}

public class Address {
private String province;
private String city;
public String getProvince() {
return province;
}
public void setProvince(String province) {
this.province = province;
}
public String getCity() {
return city;
}
public void setCity(String city) {
this.city = city;
}
@Override
public String toString() {
return "Address [province=" + province + ", city=" + city + "]";
}

}
