前面文章构建了服务提供者http://www.cookqq.com/lookBlog.action?id=8a10a5f365898f3201659d6318800652

本文构建服务消费者订单项目order调用user服务。

APP启动类

package com.cookqq.consumer;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
import org.springframework.web.client.RestTemplate;

/**
 * 订单服务
 *
 */
@SpringBootApplication
public class App 
{
	
	@Bean
	public RestTemplate restTemplate(){
		return new RestTemplate();
	}
	
    public static void main( String[] args )
    {
        SpringApplication.run(App.class, args);
    }
}

POJO类User.java

package com.cookqq.consumer.bean;

import java.math.BigDecimal;

public class User {

	private Long id;
	private String username;
	private String name;
	private Integer age;
	private BigDecimal balance;
	
	
	public Long getId() {
		return id;
	}
	public void setId(Long id) {
		this.id = id;
	}
	public String getUsername() {
		return username;
	}
	public void setUsername(String username) {
		this.username = username;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public Integer getAge() {
		return age;
	}
	public void setAge(Integer age) {
		this.age = age;
	}
	public BigDecimal getBalance() {
		return balance;
	}
	public void setBalance(BigDecimal balance) {
		this.balance = balance;
	}
	
	
	
}

order控制类OrderController

package com.cookqq.consumer.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.client.RestTemplate;

import com.cookqq.consumer.bean.User;

@RestController
public class OrderController {

	@Autowired
	private RestTemplate restTemplate;
	
	@GetMapping("/user/{id}")
	public User findUserById(@PathVariable Long id){
		return this.restTemplate.getForObject("http://127.0.0.1:8000/"+id, User.class);
	}
}
