创建menu并实现

pom.xml中编写相关依赖

<dependencies><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-netflix-eureka-client</artifactId><version>2.0.2.RELEASE</version></dependency><dependency><groupId>org.mybatis.spring.boot</groupId><artifactId>mybatis-spring-boot-starter</artifactId><version>1.3.1</version></dependency><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>8.0.27</version></dependency><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-config</artifactId><version>2.0.2.RELEASE</version></dependency>
</dependencies>

创建bootstrap.yml

先在shared里面创建

server:port: 8020
spring:application:name: menudatasource:name: orderingsystemurl: jdbc:mysql://localhost:3306/orderingsystem?useUnicode=true&characterEncoding=UTF-8username: rootpassword: rooteureka:client:service-url:defaultZone: http://localhost:8761/eureka/instance:prefer-ip-address: true

spring:application:name: menuprofiles:active: devcloud:config:uri: http://localhost:8762fail-fast: true

创建Handler启动类并测试

MenuApplication

package com.redhat;import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplication
@MapperScan("com.redhat.repository")//自动扫描
public class MenuApplication {public static void main(String[] args) {SpringApplication.run(MenuApplication.class,args);}
}

package com.redhat.controller;import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;@RestController
@RequestMapping("/menu")
public class MenuHandler {@Value("${server.port}")private String port;@GetMapping("/index")public String index(){return "menu的端口"+this.port;}
}
最后和上面一样启动测试

8020显示成功

访问mean中获得数据表示成功

新建实体类menu

package com.redhat.entity;import lombok.Data;@Data
public class Menu {private long id;private String name;private double price;private String flavor;
}
创建MenuRepository接口

package com.redhat.repository;import com.redhat.entity.Menu;import java.util.List;public interface MenuRepository {public List<Menu>findAll();public int count();public Menu findById(long id);public void save(Menu menu);public void update(Menu menu);public void deleteById(long id);
}

resources 路径下创建mapping文件夹，存放Mapper.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.redhat.repository.MenuRepository"><select id="findAll" resultType="com.redhat.entity.Menu">select*from t_menu limit #{param1},#{param2}</select><select id="count" resultType="int">select count(*) from t_menu;</select><insert id="save" parameterType="com.redhat.entity.Menu">insert into t_menu(name,price,flavor,tid) values(#{name},#{price},#{flavor},#{type.id})</insert><select id="findById" resultType="com.redhat.entity.Menu">select id mid,name mname,price,flavor,tid from t_menu where id = #{id}</select><update id="update" parameterType="com.redhat.entity.Menu">update t_menu set name = #{name},price = #{price},flavor = #{flavor},tid = #{type.id} where id = #{id}</update><delete id="deleteById" parameterType="long">delete from t_menu where id = #{id}</delete>
</mapper>

创建menu MenuHandler

package com.redhat.controller;import com.redhat.entity.Menu;
import com.redhat.repository.MenuRepository;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;import java.util.List;@RestController
@RequestMapping("/menu")
public class MenuHandler {@Value("${server.port}")private String port;@Autowiredprivate MenuRepository menuRepository;@GetMapping("/index")public String index(){return "menu的端口"+this.port;}@GetMapping("/findAll/{index}/{limit}")public List<Menu> findAll(@PathVariable("index") int index,@PathVariable("limit")  int limit){return menuRepository.findAll(index, limit);}
}在menu-dev.yml文件中加入最后两行

server:port: 8020
spring:application:name: menudatasource:name: orderingsystemurl: jdbc:mysql://localhost:3306/orderingsystem?useUnicode=true&characterEncoding=UTF-8username: rootpassword: 123456eureka:client:service-url:defaultZone: http://localhost:8761/eureka/instance:prefer-ip-address: true
mybatis:mapper-locations: classpath:/mapping/*.xmltype-aliases-package: com.redhat.entity

重新启动管理层和menu层进行测试
