JAXRS之与XML打交道


import javax.xml.bind.annotation.XmlAttribute;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;

&＃64;XmlRootElement(name &＃61; "user")
public class User {

String username;
String password;
int pin;

&＃64;XmlElement
public String getUsername() {
return username;
}

public void setUsername(String username) {
this.username &＃61; username;
}

&＃64;XmlElement
public String getPassword() {
return password;
}

public void setPassword(String password) {
this.password &＃61; password;
}

&＃64;XmlAttribute
public int getPin() {
return pin;
}

public void setPin(int pin) {
this.pin &＃61; pin;
}

}


使用JAXB后&＃xff0c;会转为如下XML&＃xff1a;

JAX-RS要返回XML的话&＃xff0c;可以通过&＃64;Produces("application/xml")标签,前提是user对象是经过jaxb的


import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;

&＃64;Path("/xml/user")
public class XMLService {

&＃64;GET
&＃64;Path("/get")
&＃64;Produces("application/xml")
public User getUserInXML() {

User user &＃61; new User();
user.setUsername("mkyong");
user.setPassword("password");
user.setPin(123456);

return user;

}

}




当运行“/xml/user/get”时&＃xff0c;就返回XML了&＃xff1a;



password

mkyong
