# 使用 Eclipse 从 JAXB Java 类生成 XSD > 原文： [https://howtodoinjava.com/jaxb/java-class-to-xsd-eclipse/](https://howtodoinjava.com/jaxb/java-class-to-xsd-eclipse/) 学习**使用 Eclipse IDE 从带有 JAXB 注解的 Java 类**创建 XML 模式文档（xsd）。 ## 1）将 JAXB 注解添加到 Java 类 第一步是向 Java 类添加`@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）从 JAXB 类生成 XSD #### 2.1）导航到 Eclipse 选项 ```java File -> New -> JAXB -> Schema from JAXB Classes ```  JAXB 类选项的模式 ## 2.2）选择生成的模式文件的位置  生成的模式文件的位置 #### 2.3）选择 JAXB 类  选择 JAXB 类 #### 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，现在您可以将其用于各种应用用例。 学习愉快！
