笔者一直有个观念，学习一个东西最好的方式是结合一个实际案例一起学习。
在本篇中，我们将开发一个简单的SIM(学生信息管理)的项目，作为我们学习springCloud的一个案例，后面的文章笔者也会基于这个案例进行更深入的开发和探讨。
好了，废话不多讲，我们先搭建这个项目。（项目基于maven构建）
sim-parent 父工程(pom工程)，提供所有子项目的顶级配置。
sim-base 基础工程，含有 model、基础util等
sim-provider 服务提供者工程
sim-consumer 服务消费者工程
数据库：db_sim，数据库中现只有一张学生表 t_student
CREATE TABLE `t_student` (
`studentId` int(11) NOT NULL AUTO_INCREMENT COMMENT '主键id',
`name` varchar(50) DEFAULT NULL COMMENT '姓名',
`birthday` varchar(24) DEFAULT NULL COMMENT '生日yyyy-MM-dd',
`phone` varchar(24) DEFAULT NULL COMMENT '手机号',
`address` varchar(200) DEFAULT NULL COMMENT '家庭地址',
`createtime` varchar(24) DEFAULT NULL COMMENT '创建时间',
PRIMARY KEY (`studentId`)
) ENGINE=InnoDB AUTO_INCREMENT=5 DEFAULT CHARSET=utf8
插入一些初始数据
INSERT INTO `t_student`(NAME ,birthday,phone,address,createtime)
VALUE('张三','1991-09-23','1357788888','北京',NOW());
INSERT INTO `t_student`(NAME ,birthday,phone,address,createtime)
VALUE('李四','1991-09-20','1357788888','广州',NOW());
INSERT INTO `t_student`(NAME ,birthday,phone,address,createtime)
VALUE('王五','1991-09-24','1357788888','杭州',NOW());
注 ： 现在这个项目暂时未使用到springcloud的任何东西(使用到了springboot)，后面我们讲一步步地进行 spring cloud化 。
sim-parent 父工程(pom工程) ,项目代码如下：

sim-consumer 服务消费者工程 ,项目代码如下：
学生controller ，springboot入口类 ，等。
StudentConsumerController.java
package com.tingcream.simConsumer.controller;
import java.util.List;
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.tingcream.simBase.model.Student;
@RestController
@RequestMapping("/student")
public class StudentConsumerController {
@Autowired
private RestTemplate restTemplate;
private String PRE_URL="http://localhost:7001/";
/**
* 学生列表 list
* @return
*/
@SuppressWarnings("unchecked")
@GetMapping("/list")
public List<Student> list(){
return restTemplate.getForObject(PRE_URL+"/student/list", List.class);
}
/**
* 根据id查询一个学生
* @return
*/
@GetMapping(value="/get/{id}")
public Student get(@PathVariable("id") Integer id){
return restTemplate.getForObject(PRE_URL+"/student/get/"+id, Student.class);
}
/**
* 根据id删除一个学生
* @return
*/
@GetMapping(value="/delete/{id}")
public boolean delete(@PathVariable("id") Integer id){
return restTemplate.getForObject(PRE_URL+"/student/delete/"+id, Boolean.class);
}
/**
* 添加学生
* @param student
* @return
*/
@PostMapping(value="/save")
public boolean save(Student student){
return restTemplate.postForObject(PRE_URL+"/student/save", student, Boolean.class);
}
/**
* 修改学生
* @param student
* @return
*/
@PostMapping(value="/update")
public boolean update(Student student){
return restTemplate.postForObject(PRE_URL+"/student/update", student, Boolean.class);
}
}
MyConfiguration.java
package com.tingcream.simConsumer.configuration;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.client.RestTemplate;
@Configuration
public class MyConfiguration {
/**
* 定义调用rest服务模版对象
*/
@Bean
public RestTemplate restTemplate(){
return new RestTemplate();
}
}
SimConsumerApp.java
package com.tingcream.simConsumer;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.SpringBootConfiguration;

@EnableAutoConfiguration
@ComponentScan
public class SimConsumerApp extends SpringBootServletInitializer{
//实现SpringBootServletInitializer接口 ，需实现此方法。 可以war包形式 发布到tomcat中
@Override
protected SpringApplicationBuilder configure(
SpringApplicationBuilder builder) {
return builder.sources(SimConsumerApp.class);
}
public static void main(String[] args) {
SpringApplication.run(SimConsumerApp.class, args);
}
}

ok，一个简单的RESTFull 风格的学生信息管理项目就搭建完成了 。
依次启动服务提供者 SimProviderApp 和服务消费者SimConsumerApp ，浏览器访问 http://localhost:7001/student/list http://localhost/student/list 查询学生列表。
