　　jersey 配置类

/**
 * 配置 jersey rest api 资源路径, Spring Boot建议在使用
 * ResourceConfig添加资源类的时候，不要使用packages方法去自动扫描，建议还是使用register添加。
 * 
 * 注解ApplicationPath，默认为/*
 * 
 */
@Component
@ApplicationPath("/jersey")
public class JerseyConfig extends ResourceConfig  {
    
    public JerseyConfig() {
        //packages("com.oy"); // 扫描 com.oy 包，使其识别 JAX-RS 注解
        register(UserController.class);
    }
    
}

　　模型类

package com.oy.model;

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

@XmlRootElement(name = "user") // 将该类转化成XML时，说明这个是XML的根节点
public class User {
    private String name;
    private String email;
    
    public User() {}
    
    public User(String name, String email) {
        this.name = name;
        this.email = email;
    }

    @XmlAttribute // 属性
    public String getName() {
        return name;
    }

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

    @XmlElement // 节点
    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
