# 使用 Eclipse 從 JAXB Java 類生成 XSD > 原文： [https://howtodoinjava.com/jaxb/java-class-to-xsd-eclipse/](https://howtodoinjava.com/jaxb/java-class-to-xsd-eclipse/) 學習**使用 Eclipse IDE 從帶有 JAXB 注解的 Java 類**創建 XML 模式文檔（xsd）。 ## 1）將 JAXB 注解添加到 Java 類 第一步是向 Java 類添加`@XmlRootElement`，`@XmlAccessorType`和`@XmlElement`等注解。 ```java import java.io.Serializable; import javax.xml.bind.annotation.XmlAccessType; import javax.xml.bind.annotation.XmlAccessorType; import javax.xml.bind.annotation.XmlRootElement; @XmlRootElement(name = "employee") @XmlAccessorType(XmlAccessType.PROPERTY) public class Employee implements Serializable { private static final long serialVersionUID = 1L; private Integer id; private String firstName; private String lastName; private Department department; public Employee() { super(); } //Setters and Getters } ``` ```java import java.io.Serializable; import javax.xml.bind.annotation.XmlAccessType; import javax.xml.bind.annotation.XmlAccessorType; import javax.xml.bind.annotation.XmlRootElement; @XmlRootElement(name = "department") @XmlAccessorType(XmlAccessType.PROPERTY) public class Department implements Serializable { private static final long serialVersionUID = 1L; Integer id; String name; public Department() { super(); } //Setters and Getters } ``` ## 2）從 JAXB 類生成 XSD #### 2.1）導航到 Eclipse 選項 ```java File -> New -> JAXB -> Schema from JAXB Classes ```  JAXB 類選項的模式 ## 2.2）選擇生成的模式文件的位置  生成的模式文件的位置 #### 2.3）選擇 JAXB 類  選擇 JAXB 類 #### 2.4）生成 xsd 文件 ```java <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <xs:schema version="1.0" xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:element name="department" type="department"/> <xs:element name="employee" type="employee"/> <xs:complexType name="employee"> <xs:sequence> <xs:element ref="department" minOccurs="0"/> <xs:element name="firstName" type="xs:string" minOccurs="0"/> <xs:element name="id" type="xs:int" minOccurs="0"/> <xs:element name="lastName" type="xs:string" minOccurs="0"/> </xs:sequence> </xs:complexType> <xs:complexType name="department"> <xs:sequence> <xs:element name="id" type="xs:int" minOccurs="0"/> <xs:element name="name" type="xs:string" minOccurs="0"/> </xs:sequence> </xs:complexType> </xs:schema> ``` XSd 文件已生成，現在您可以將其用于各種應用用例。 學習愉快！
