xml沒有填充 - 使用JAXB

大家晚上好。我在學校的實驗室遇到了一些問題。實質上，我必須創建一個XML Schema，運行JAXB編譯器，然後創建Java類來序列化en員工記錄。xml沒有填充 - 使用JAXB

所以這是我到目前爲止有：被稱爲「employeeSchema.xsd」

<?xml version="1.0" encoding="UTF-8"?> 
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" 
     xmlns:jxb="http://java.sun.com/xml/ns/jaxb" 
     jxb:version="2.0"> 

<xs:element name="employee" type="employeeType"/> 

<xs:complexType name="jobListType"> 
    <xs:sequence> 
     <xs:element name="job_id" type="xs:positiveInteger"/> 
     <xs:element name="job_title" type="xs:string"/> 
     <xs:element name="min_salary" type="xs:positiveInteger"/> 
     <xs:element name="max_salary" type="xs:positiveInteger"/> 
    </xs:sequence> 
</xs:complexType> 

<xs:complexType name="departmentType"> 
    <xs:sequence> 
     <xs:element name="department_id" type="xs:positiveInteger"/> 
     <xs:element name="department_name" type="xs:string"/> 
     <xs:element name="manager_id" type="xs:positiveInteger"/> 
     <xs:element name="location_id" type="xs:positiveInteger"/> 
    </xs:sequence> 
</xs:complexType> 

<xs:complexType name="employeeType"> 
    <xs:sequence> 
     <xs:element name="employee_id" type="xs:positiveInteger"/> 
     <xs:element name="first_name" type="xs:string"/> 
     <xs:element name="last_name" type="xs:string"/> 
     <xs:element name="email" type="xs:string"/> 
     <xs:element name="phone_number" type="xs:string"/> 
     <xs:element name="hire_date" type="xs:date"/> 
     <xs:element name="job" type="jobListType"/> 
     <xs:element name="salary" type="xs:positiveInteger"/>  
     <xs:element name="commission_pct" type="xs:decimal"/> 
     <xs:element name="manager_id" type="xs:positiveInteger"/> 
     <xs:element name="department" type="departmentType"/>    
    </xs:sequence> 
</xs:complexType> 

</xs:schema>

一個文件，一旦我把它用JAXB遵守，我創造了這個班叫做「employee.java」

package employeeSchema; 

import java.text.DateFormat; 
import java.text.SimpleDateFormat; 
import java.util.*; 
import javax.xml.bind.*; 
import javax.xml.datatype.DatatypeFactory; 
import javax.xml.datatype.XMLGregorianCalendar; 
import java.math.*; 

public class employee { 

private ObjectFactory of; 
private EmployeeType myEmployee; 

public employee(){ 
    of = new ObjectFactory(); 
    myEmployee = of.createEmployeeType(); 
} 

public void make(BigInteger empID, String firstName, String lastName, String email, String phoneNumber, 
     Date hireDate, JobListType jobID, BigInteger salary, BigDecimal commPct, 
     BigInteger managerID/*, DepartmentType departmentID*/){ 

    try{ 
     GregorianCalendar gcal = new GregorianCalendar(); 
     gcal.setTime(hireDate); 
     XMLGregorianCalendar xgcal = DatatypeFactory.newInstance().newXMLGregorianCalendar(gcal); 


     EmployeeType emp = of.createEmployeeType(); 

     emp.setEmployeeId(empID); 
     emp.setFirstName(firstName); 
     emp.setLastName(lastName); 
     emp.setEmail(email); 
     emp.setPhoneNumber(phoneNumber); 
     emp.setHireDate(xgcal); 
     emp.setJob(jobID); 
     emp.setSalary(salary); 
     emp.setCommissionPct(commPct); 
     emp.setManagerId(managerID); 

    } 

    catch (Exception e){ 
    } 
} 

public void marshal() { 
    try { 
     JAXBElement<EmployeeType> em = 
      of.createEmployee(myEmployee); 
     JAXBContext jc = JAXBContext.newInstance("employeeSchema"); 
     Marshaller m = jc.createMarshaller(); 
     m.marshal(em, System.out); 
    } catch(JAXBException jbe){ 
     // ... 
    } 
} 


public static void main(String args[]) 
{ 
    int employeeID = 123456;   
    BigInteger empID = BigInteger.valueOf(employeeID); 


    String firstName = "Ehssan"; 
    String lastName = "Tehrani"; 
    String email = "[email protected]"; 

    Date hireDate = null; 
    try{ 
     DateFormat df=new SimpleDateFormat("dd/MM/yyyy"); 
     hireDate=df.parse("20/02/2014"); 
    } 

    catch (Exception e){ 
    } 


    String phoneNumber = "647-588-3774"; 

    JobListType jList = new JobListType(); 

    int theJobId = 12345; 
    BigInteger jID = BigInteger.valueOf(theJobId); 
    jList.setJobId(jID); 

    jList.setJobTitle("Java Developer"); 

    int theMinSal = 50000; 
    BigInteger jMinSal = BigInteger.valueOf(theMinSal); 
    jList.setMinSalary(jMinSal); 

    int theMaxSal = 150000; 
    BigInteger jMaxSal = BigInteger.valueOf(theMaxSal); 
    jList.setMinSalary(jMaxSal); 

    int theSalary = 90000; 
    BigInteger salary = BigInteger.valueOf(theSalary); 

    BigDecimal commPct = new BigDecimal(5.0); 

    int theManagerID = 12345; 
    BigInteger managerID = BigInteger.valueOf(theManagerID); 

//DepartmentType departmentID 
    //setDepartmentID 

    employee myEmp = new employee(); 

    myEmp.make(empID, firstName, lastName, email, phoneNumber, hireDate, jList, salary, commPct, managerID); 

    myEmp.marshal(); 
} 
}

然而，當我運行employee.java，我的輸出如下：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?><employee/>

但目的是爲了顯示主要定義的員工。任何形式的建議或幫助將不勝感激。

非常感謝您提前。

乾杯

具有u使用XJC命令從XSD生成Java類？ – Naren

@Naren：是的，我創建XSD後，我做了以下幾點：jxc -p employeeSchema employeeSchema.xsd ...它編寫得很好，並創建了OjbectFactory和相關文件。 –

你可以這樣做

謝謝@Naren，但我相信教練希望我們使用她提供給我們的模板（我發佈的方式）......她的示例有效，但由於某種原因，我的工作不正常。我將繼續堵塞走...非常感謝您的意見。我會試試你的方法來更好地理解它們。謝謝 –

歡迎您@EssiJoon – Naren
