用JAXB从对象生成XML

import java.io.FileOutputStream;

import javax.xml.bind.JAXBContext;
import javax.xml.bind.Marshaller;
import javax.xml.bind.annotation.XmlRootElement;

public class JavaToXMLDemo {
 public static void main(String[] args) throws Exception {
 JAXBContext context = JAXBContext.newInstance(Employee.class);

 Marshaller m = context.createMarshaller();
 m.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);

 Employee object = new Employee();
 object.setCode("CA");
 object.setName("Cath");
 object.setSalary(300);

 m.marshal(object, System.out);

 }
}

import java.io.FileOutputStream;

import javax.xml.bind.JAXBContext;
import javax.xml.bind.Marshaller;
import javax.xml.bind.annotation.XmlRootElement;

public class JavaToXMLDemo {
  public static void main(String[] args) throws Exception {
    JAXBContext context = JAXBContext.newInstance(Employee.class);

    Marshaller m = context.createMarshaller();
    m.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);

    Employee object = new Employee();
    object.setCode("CA");
    object.setName("Cath");
    object.setSalary(300);

    m.marshal(object, System.out);

  }
}

 

 

@XmlRootElement
class Employee {
 private String code;

 private String name;

 private int salary;

 public String getCode() {
 return code;
 }

 public void setCode(String code) {
 this.code = code;
 }

 public String getName() {
 return name;
 }

 public void setName(String name) {
 this.name = name;
 }

 public int getSalary() {
 return salary;
 }

 public void setSalary(int population) {
 this.salary = population;
 }
}

@XmlRootElement
class Employee {
  private String code;

  private String name;

  private int salary;

  public String getCode() {
    return code;
  }

  public void setCode(String code) {
    this.code = code;
  }

  public String getName() {
    return name;
  }

  public void setName(String name) {
    this.name = name;
  }

  public int getSalary() {
    return salary;
  }

  public void setSalary(int population) {
    this.salary = population;
  }
}

 

 

运行结果:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<employee>
 <code>CA</code>
 <name>Cath</name>
 <salary>300</salary>
</employee>

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<employee>
    <code>CA</code>
    <name>Cath</name>
    <salary>300</salary>
</employee>
