RESTEasy使用json返回的例子

创建一个json的model类：

[java] view plain copy

package com.howtodoinjava.model;

import java.io.Serializable;

import javax.xml.bind.annotation.XmlAccessType;

import javax.xml.bind.annotation.XmlAccessorType;

import javax.xml.bind.annotation.XmlAttribute;

import javax.xml.bind.annotation.XmlElement;

import javax.xml.bind.annotation.XmlRootElement;

@XmlAccessorType(XmlAccessType.NONE)

@XmlRootElement(name = "user")

public class User implements Serializable {

private static final long serialVersionUID = 1L;

@XmlAttribute(name = "id")

private int id;

@XmlElement(name = "firstName")

private String firstName;

@XmlElement(name = "lastName")

private String lastName;

public int getId() {

return id;

}

public void setId(int id) {

this.id = id;

}

public String getFirstName() {

return firstName;

}

public void setFirstName(String firstName) {

this.firstName = firstName;

}

public String getLastName() {

return lastName;

}

public void setLastName(String lastName) {

this.lastName = lastName;

}

}

2、创建一个服务器回调类：

[java] view plain copy

UserManagementModule.java

[java] view plain copy

package com.howtodoinjava.service;

import javax.ws.rs.GET;

import javax.ws.rs.Path;

import javax.ws.rs.PathParam;

import javax.ws.rs.core.Response;

import com.howtodoinjava.model.User;

@Path("/user-management")

public class UserManagementModule

{

@GET

@Path("/users/{id}")

@Produces("application/json")

public Response getUserById(@PathParam("id") Integer id)

{

User user = new User();

user.setId(id);

user.setFirstName("Lokesh");

user.setLastName("Gupta");

return Response.status(200).entity(user).build();

}

}

3、应用测试
