最近使用微服务(这年头啥东西都要微服务),作为Nutz组里唯一一个打酱油的,难道要跟一般人一样用Springboot+MyBatis?
这不是我风格呀,看了下Onekey的demo,发现居然要写application.yml,yml之类的东西最讨厌了。。
所以直接改写了下,基本上不需要啥配置的,springboot-nutz-starter是个好东西,直接Nutz.dao、Nutz.Json用起来,
废话少说下面贴代码。

application.properties

数据源配置

https://github.com/alibaba/druid/tree/master/druid-spring-boot-starter

spring.datasource.druid.url=jdbc:mysql://120.24.240.16:3306/test?useUnicode=true&characterEncoding=UTF-8&useSSL=false
spring.datasource.druid.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.druid.username=test
spring.datasource.druid.password=l6ZzXMs8PDVhexy4hSPBUMZ0rqGhxX5KJwOBptltZ5c5KlV6cgtUzAul0ERVjE2SnB7qUUq3g1+pa04MDlqJYQ==

配置 connection-properties,启用加密,配置公钥。

spring.datasource.druid.connection-properties=config.decrypt=true;config.decrypt.key=MFwwDQYJKoZIhvcNAQEBBQADSwAwSAJBAKjST2Dg5nbaoFaUOxjiCz2Qzu9tMkGMRg7e0g2cE0gbHJhnDJlinZX1CIqMSdw47VuqJaUxMECm9hephb9qee0CAwEAAQ==

启动ConfigFilter

spring.datasource.druid.filter.config.enabled=true

初始化大小,最小,最大

spring.datasource.druid.initial-size=5
spring.datasource.druid.min-idle=5
spring.datasource.druid.max-active=20

配置获取连接等待超时的时间

spring.datasource.druid.max-wait=60000

配置间隔多久才进行一次检测,检测需要关闭的空闲连接,单位是毫秒

spring.datasource.druid.time-between-eviction-runs-millis=60000

配置一个连接在池中最小生存的时间,单位是毫秒

spring.datasource.druid.min-evictable-idle-time-millis=300000

检测连接是否有效的sql

spring.datasource.druid.validation-query=SELECT 'x'
spring.datasource.druid.validation-query-timeout=60000
spring.datasource.druid.test-while-idle=true
spring.datasource.druid.test-on-borrow=false
spring.datasource.druid.test-on-return=false

PSCache Mysql下建议关闭

spring.datasource.druid.pool-prepared-statements=false
spring.datasource.druid.max-pool-prepared-statement-per-connection-size=-1

spring.datasource.druid.max-open-prepared-statements= #等价于上面的max-pool-prepared-statement-per-connection-size

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

spring.datasource.druid.filters=stat,wall,log4j

WebStatFilter配置,说明请参考Druid Wiki,配置_配置WebStatFilter

启动项目后访问 http://127.0.0.1:8080/druid

是否启用StatFilter默认值true

spring.datasource.druid.web-stat-filter.enabled=true
spring.datasource.druid.web-stat-filter.url-pattern=/*
spring.datasource.druid.web-stat-filter.exclusions=*.js,*.gif,*.jpg,*.bmp,*.png,*.css,*.ico,/druid/*

缺省sessionStatMaxCount是1000个

spring.datasource.druid.web-stat-filter.session-stat-max-count=1000

关闭session统计功能

spring.datasource.druid.web-stat-filter.session-stat-enable=false

配置principalSessionName,使得druid能够知道当前的session的用户是谁

如果你session中保存的是非string类型的对象,需要重载toString方法

spring.datasource.druid.web-stat-filter.principalSessionName=xxx.user

如果user信息保存在cookie中,你可以配置principalCookieName,使得druid知道当前的user是谁

spring.datasource.druid.web-stat-filter.principalCookieName=xxx.user

druid 0.2.7版本开始支持profile,配置profileEnable能够监控单个url调用的sql列表。

spring.datasource.druid.web-stat-filter.profile-enable=false

StatViewServlet配置,说明请参考Druid Wiki,配置_StatViewServlet配置

是否启用StatViewServlet默认值true

spring.datasource.druid.stat-view-servlet.enabled=true
spring.datasource.druid.stat-view-servlet.urlPattern=/druid/*

禁用HTML页面上的“Reset All”功能

spring.datasource.druid.stat-view-servlet.resetEnable=false

用户名

spring.datasource.druid.stat-view-servlet.loginUsername=admin

密码

spring.datasource.druid.stat-view-servlet.loginPassword=admin

IP白名单(没有配置或者为空,则允许所有访问)

spring.datasource.druid.stat-view-servlet.allow=127.0.0.1,192.168.163.1

IP黑名单 (存在共同时,deny优先于allow)

spring.datasource.druid.stat-view-servlet.deny=192.168.1.73

日志配置

logging.level.com.caiyouxi=debug
logging.level.org.springframework.web=debug
logging.level.org.springframework.transaction=debug
logging.level.org.mybatis=debug

debug=false

```

driver配置错了吗?应如何解决问题

去掉driver: com.mysql.jdbc.Driver ,不需要配置的

一直用 nutz-plugins-spring-boot-starter coding起来带风啊

启动器内置了baseService 用起来更带风
