springboot和springcloud步骤总结

springboot

搭建环境

1.父级和common为quickstart，provider和consumer为Initialzr

​ 父级pom修改test添加分页插件

2.common创建vo和service包：vo要序列化，日期改为String类型

3.provider创建mapper和service包(@Service@Transactional)

​ resource创建mapper映射文件EntryMapper.xml
添加spring-provider.xml文件
填写application.properties
​ 启动项：@ImportResource(“classpath:spring-provider.xml”)
​ @MapperScan(“cn.kgc.mapper”)

4.consumer创建controller(@RestController@RequestMapping@RequestBody)

​ application.properties
​ 添加spring-consumer.xml
​ 启动项：ImportResource(“classpath:spring-consumer.xml”)

application.properties***********

(接口，数据源，包，地址，方言)

server.port=9090

spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/test
spring.datasource.username=root
spring.datasource.password=123.

mybatis.type-aliases-package=cn.kgc.vo
mybatis.mapper-locations=classpath:mapper/*.xml
pagehelper.helper-dialect=mysql

EntryMapper.xml************************

namespace
id="showData" parameterType="Student" resultType="map"
select c.name,e.* from entry e,category c where e.categoryId=c.id
categoryId!=null and categoryId!=-1
and e.categoryId=#{categoryId}
and e.name like concat('%',#{name},'%')

EntryServiceImpl****************************

public PageInfo<Map<String,Object>>(Integer pageno,Entry entry){
	PageHelp.startPage(pageno,3);
	List<Map<String,Object>> list=entryMapper.showData(entry);    
	return new PageInfo<Map<String,Object>>(list);
    }

springcloud

1.Initialzr创建eureka-server,勾选web，Server 勾选个数【2】

​ 添加启动项@EnableEurekaServer
​ 配置里5: 端口，name，register,fetch,url

2.quickstart创建common-info，建vo（vo序列化）

​ 打包公共组件install

3.Initailzr创建eureka-provider-one多选Client 【5】

​ pom里添加公共组件，分页插件，修改mysql版本
​ 建mapper接口和对应的.xml文件
​ service四个文件，@service@Transactional
​ controller@RestController@RequestMapping@RequestBody
​ 启动项添加@EnableEurekaClient@MapperScan(“cn.kgc.mapper”)
​ application.properties配置:端口号，name,url,数据源（4），包，位置，dialect

4.创建eureka-provider-two，修改端口号

5.创建eureka-consumer，勾选web，client，OpenFeign 【3】

​ 创建controller，CenterController
​ 创建feign，CenterFeign接口@FeignClient,改String类型
​ 创建CenterFeignFallBack@Component，
​ 添加注解@FeignClient(name=“provider”,fallback=CenterFeignFallBack.class)
​ 启动注解：@EnableEurekaClient@EnableFeignClients
​ 配置：server.port,name,url,feign(,ribbon)

6.eureka-zuul,选web，Client，zuul 【3】

​ 启动项：@EnableEurekaClient@EnableZuulProxy
​ 配置文件：端口，name，url，zuul.routes.provider(consumer)=/pro(con)/**/
