各位读者，大家好！
新建一个springCloud项目。需要我们配置最基本的配置文件。
1. 配置yml文件如下：
1 spring:
2 application:
3 name: custom-output
4 cloud:
5 config:
6 discovery:
7 # 是否启用配置中心
8 enabled: true
9 serviceId: config-server
10 # 获取配置的策略
11 profile: ${spring.profiles.active}
12 password: root1234
13 username: user
14 # 读取配置中心的分支名
15 label: master
16 # 设置配置文件的名称
17 name: custom-output
18 fail-fast: false
19 retry:
20 initial-interval: 3600000
21 max-attempts: 1
22 max-interval: 3600000
23 multiplier: 0.1
24 # 部署所属环境
25 profiles:
26 active: dev
27
28 eureka:
29 instance:
30 prefer-ip-address: true
31 instance-id: ${spring.cloud.client.ipAddress}:${server.port}
32 client:
33 service-url:
34 # 注册中心地址
35 defaultZone: http://registerserver-pool.${DOMAIN}:8889/eureka
36 register-with-eureka: true
37 fetch-registry: true
38
39 server:
40 # 接口访问前缀
41 context-path: /third
42 # 服务端口
43 port: 8009
44 connection-timeout: 120000
45
46 mybatis:
47 # 指定xml文件路径（若mapper类和mapper.xml不在同一个路径下时需要配置）
48 mapper-locations: classpath*:mybatis/*.xml
49 configuration:
50 cache-enabled: false
51
52 management:
53 health:
54 rabbit:
55 enabled: false
56
57 feign:
58 hystrix:
59 enabled: true
60 hystrix:
61 threadpool:
62 default:
63 coreSize: 500
64 command:
65 default:
66 fallback:
67 isolation:
68 semaphore:
69 maxConcurrentRequests: 1000
70 execution:
71 timeout:
72 enabled: true
73 isolation:
74 thread:
75 timeoutInMilliseconds: 60000
76 ribbon:
77 ReadTimeout: 60000
78 ConnectTimeout: 10000
2. 当然也可以配置.properties文件，会先读取yml文件，再读取.properties文件，如果配置冲突。最终会以.properties中配置为准，也可以把yml中的配置到.properties文件中，如下application-dev.properties文件：
1 #熔断配置
2 hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds=120000
3 hystrix.threadpool.default.coreSize=100
4 #Hystrix支持，如果为true，hystrix库必须在classpath中
5 feign.hystrix.enabled=true
6 #ribbon设置
7 ribbon.ConnectTimeout=120000
8 ribbon.ReadTimeout=120000
9
10 # 数据源连接设置
11 spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
12 # 指定driver的类名，默认从jdbc url中自动探测
13 spring.datasource.driverClassName=com.mysql.jdbc.Driver
14 spring.datasource.url=jdbc:mysql://host:3306/dbname?useUnicode=true&allowMultiQuerie=true&characterEncoding=utf-8&zeroDateTimeBehavior=convertToNull
15 spring.datasource.username=uname
16 spring.datasource.password=password
17 # 初始化连接
18 spring.datasource.initialSize=5
19 # 最小空闲连接
20 spring.datasource.minIdle=5
21 # 最大连接数量
22 spring.datasource.maxActive=20
23 # 超时等待时间 60秒
24 spring.datasource.maxWait=60000
25 # 指定空闲连接检查、废弃连接清理、空闲连接池大小调整之间的操作时间间隔
26 spring.datasource.timeBetweenEvictionRunsMillis=60000
27 # 指定一个空闲连接最少空闲多久后可被清除.
28 spring.datasource.minEvictableIdleTimeMillis=300000
29 # 指定获取连接时连接校验的sql查询语句.
30 spring.datasource.validationQuery=SELECT 1 FROM DUAL
31 # 当连接空闲时，是否执行连接测试.
32 spring.datasource.testWhileIdle=true
33 # 当从连接池借用连接时，是否测试该连接.
34 spring.datasource.testOnBorrow=false
35 # 在连接归还到连接池时是否测试该连接.
36 spring.datasource.testOnReturn=false
37 # 指定是否池化statements.
38 spring.datasource.poolPreparedStatements=true
39 spring.datasource.maxPoolPreparedStatementPerConnectionSize=20
40 # 配置监控统计拦截的filters，去掉后监控界面sql无法统计，‘wall‘用于防火墙
41 spring.datasource.filters=stat,wall,log4j
42 # 是否在自动回收超时连接的时候打印连接的超时错误
43 spring.datasource.logAbandoned=true
44 # 是否自动回收超时连接
45 spring.datasource.removeAbandoned=true
46 # 超时时间(以秒数为单位)
47 spring.datasource.removeAbandonedTimeout=180
48 # 通过connectProperties属性来打开mergeSql功能；慢SQL记录
49 spring.datasource.connectionProperties=druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000
50
51 # REDIS配置
52 spring.redis.database=0
53 spring.redis.host=redis.test.baiwang-inner.com
54 spring.redis.port=6379
55 spring.redis.password=rm$wdFcZd0gdJ*WD
56 spring.redis.pool.max-active=200
57 spring.redis.pool.max-wait=10000
58 spring.redis.pool.max-idle=50
59 spring.redis.pool.min-idle=5
60 spring.redis.timeout=10000
61
62 # 日志级别(用于log4j日志打印配置)
63 logging.level.com.baiwang.cloud.output=DEBUG
64
65 # 第三方系统地址
66 custom.third.requestUrl=http://
注意：在yml中遇到-的配置，则首字母需要大写，比如配置eureka.client.service-url.defaultZone则需要写为eureka.client.serviceUrl.defaultZone=http:localhost:8889/eureka
3. 启动主类
1 package com.cheng2839;
2
3 import com.github.pagehelper.PageHelper;
4 import org.mybatis.spring.annotation.MapperScan;

27 @ComponentScan(basePackages = {"com.cheng2839"})
28 public class Application {
29
30 public static void main(String[] args) {
31 SpringApplication.run(Application.class, args);
32 }
33
34 // 创建事务管理器
35 @Bean(name = "transactionManager")
36 public PlatformTransactionManager txManager(DataSource dataSource) {
37 return new DataSourceTransactionManager(dataSource);
38 }
39
40 /**
41 * 配置mybatis的分页插件pageHelper
42 *
43 * @return
44 */
45 @Bean
46 public PageHelper pageHelper() {
47 PageHelper pageHelper = new PageHelper();
48 Properties properties = new Properties();
49 properties.setProperty("offsetAsPageNum", "true");
50 properties.setProperty("rowBoundsWithCount", "true");
51 properties.setProperty("reasonable", "true");
52 // 配置mysql数据库的方言
53 properties.setProperty("dialect", "mysql");
54 pageHelper.setProperties(properties);
55 return pageHelper;
56 }
57
58 @Bean
59 public MultipartConfigElement multipartConfigElement() {
60 MultipartConfigFactory factory = new MultipartConfigFactory();
61 //单个文件最大
62 factory.setMaxFileSize(ThirdConstants.FILE_MAX_FILE_SIZE);
63 /// 设置总上传数据总大小
64 factory.setMaxRequestSize(ThirdConstants.FILE_MAX_REQUEST_SIZE);
65 return factory.createMultipartConfig();
66 }
67 }

注意：其中pom文件中很多是不需要的依赖，直接去掉即可
