springcloud relying on springBoot, springBoot can leave springcloud,
But springcloud not leave springBoot
Spring Boot is Spring of a fast configuration Scaffolding, based on Spring Boot rapid development of single
Micro-service, the Spring Cloud is based on Spring Boot cloud application development tools to achieve; Spring Boot professionals
Note to quickly and easily integrated single individual micro-services, the Spring Cloud attention of global service governance framework;
The following figure such as the establishment of the project

Create an entity class in the microservice_cloud_02_api
package com.yuan.springcloud.entities; public class Product { //跨服调用必须实现序列化 private long id; private String productName; private String dbSource; public long getId() { return id; } public void setId(long id) { this.id = id; } public String getProductName() { return productName; } public void setProductName(String productName) { this.productName = productName; } public String getDbSource() { return dbSource; } public void setDbSource(String dbSource) { this.dbSource = dbSource; } @Override public String toString() { return "Product{" + "id=" + id + ", productName='" + productName + '\'' + ", dbSource='" + dbSource + '\'' + '}'; } }

03中的建立controller、service、mapper
productmapper应放入resources-》mapper中否则会报错
