spring boot创建和数据库关联模块详解

spring boot创建和数据库关联模块详解

创建步骤

1.导入依赖

2.配置文件

3.创建启动类

1.导入依赖

org.springframework.cloud

spring-cloud-starter-openfeign

provided

javax.persistence

persistence-api

1.0

compile

org.springframework.cloud

spring-cloud-starter-netflix-eureka-client

com.xx

common_db

1.0-SNAPSHOT

com.xx

service_goods_api

1.0-SNAPSHOT

2.配置文件

server:

port: 9011

spring:

application:

name: goods

datasource:

driver-class-name: com.mysql.jdbc.Driver

url: jdbc:mysql://192.168.200.128:3306/goods?useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTC

username: root

password: root

eureka:

client:

service-url:

defaultZone: http://127.0.0.1:6868/eureka

instance:

prefer-ip-address: true

feign:

hystrix:

enabled: true

#hystrix 配置

hystrix:

command:

default:

execution:

timeout:

#如果enabled设置为false，则请求超时交给ribbon控制

enabled: true

isolation:

strategy: SEMAPHORE

3.创建启动类

@SpringBootApplication

@EnableEurekaClient

//@MapperScan是tk.mybatis.spring.annotation包下的，用于扫描Mapper接口*

@MapperScan(basePackages = {"com.goods.dao"})

public class GoodsApplication {

public static void main(String[] args) {

SpringApplication.run(GoodsApplication.class);

}

}
