springclound项目基础配置

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

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 }

    4. pom文件配置
