Spring Cloud搭建服务消费者项目

作用

用于消费服务

新建Module

该Module为Maven项目，命名为microservice-student-consumer-80

修改pom.xml

SpringCloud相关配置

package com.ledao.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.client.RestTemplate;

/**
 * SpringCloud相关配置
 *
 * @author LeDao

@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class, HibernateJpaAutoConfiguration.class})
public class StudentConsumerApplication_80 {

    public static void main(String[] args) {
        SpringApplication.run(StudentConsumerApplication_80.class, args);
    }
}
