Grails3默认数据库连接池为
tomcat-jdbc pool
,性能较druid
、HikariCP
差太多,所以想换成其他连接池
由于默认使用的是tomcat-jdbc
连接池,需要去掉依赖
// runtime "com.h3database:h3" // runtime "org.apache.tomcat:tomcat-jdbc" // 添加阿里巴巴druid连接池 compile group: 'com.alibaba', name: 'druid', version: '1.1.18' compile 'MySQL:mysql-connector-java:5.1.40'
grails-app/conf/applicaiton.yml
配置也要注释掉默认的连接池
dataSource: # pooled: true jmxExport: true driverClassName: com.mysql.jdbc.Driver username: root password: root dialect: org.hibernate.dialect.MySQL5InnoDBDialect url: jdbc:mysql://localhost:3306/g3?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull&useSSL=false # 为了兼容grails,让Hibernate自动建表,所以在dataSource下增加连接池相关的配置 druid: minIdle: 1 maxActive: 40 maxWait: 60000 initialSize: 20 testWhileIdle: true testOnBorrow: false testOnReturn: false removeAbandoned: true filters: stat,wall,slf4j validationQuery: select 'x' useGlobalDataSourceStat: true poolPreparedStatements: true minEvictableIdleTimeMillis: 300000 timeBetweenEvictionRunsMillis: 60000 connectionProperties: clientEncoding=UTF-8 maxPoolPreparedStatementPerConnectionSize: 20 environments: development: dataSource: dbCreate: create-drop url: jdbc:mysql://localhost:3306/g3?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull&useSSL=false test: dataSource: dbCreate: update url: jdbc:mysql://localhost:3306/g3?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull&useSSL=false production: dataSource: dbCreate: update url: jdbc:mysql://localhost:3306/g3?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull&useSSL=false server: port: 8081 # TRANSACTION_READ_COMMITTED
grails-app/conf/spring/resources.groovy
配置
// Place your Spring DSL code here beans = { // 监控管理页面配置(管理用户名、密码) druidConsoleServlet(org.springframework.boot.web.servlet.ServletRegistrationBean) { servlet = bean(com.alibaba.druid.support.http.StatViewServlet) urlMappings = ["/druid/*"] // urlMappings = ["*.js","*.gif","*.jpg","*.png","*.css","*.ico","/druid/*"] initParameters = [ "loginUsername": "root", "loginPassword": "123456", "allow": "127.0.0.1", "deny": "" ] // loadOnStartup = 2 } // alibaba druid配置 dataSource(com.alibaba.druid.pool.DruidDataSource) { bean -> bean.initMethod = 'init' bean.destroyMethod = 'close' driverClassName = grailsApplication.config.dataSource.driverClassName url = grailsApplication.config.dataSource.url username = grailsApplication.config.dataSource.username password = grailsApplication.config.dataSource.password initialSize = grailsApplication.config.dataSource.druid.initialSize minIdle = grailsApplication.config.dataSource.druid.minIdle maxActive = grailsApplication.config.dataSource.druid.maxActive maxWait = grailsApplication.config.dataSource.druid.maxWait timeBetweenEvictionRunsMillis = grailsApplication.config.dataSource.druid.timeBetweenEvictionRunsMillis minEvictableIdleTimeMillis = grailsApplication.config.dataSource.druid.minEvictableIdleTimeMillis validationQuery = grailsApplication.config.dataSource.druid.validationQuery removeAbandoned = grailsApplication.config.dataSource.druid.removeAbandoned testWhileIdle = grailsApplication.config.dataSource.druid.testWhileIdle connectionProperties = grailsApplication.config.dataSource.druid.connectionProperties testOnBorrow = grailsApplication.config.dataSource.druid.testOnBorrow poolPreparedStatements = grailsApplication.config.dataSource.druid.poolPreparedStatements testOnReturn = grailsApplication.config.dataSource.druid.testOnReturn useGlobalDataSourceStat = grailsApplication.config.dataSource.druid.useGlobalDataSourceStat maxPoolPreparedStatementPerConnectionSize = grailsApplication.config.dataSource.druid.maxPoolPreparedStatementPerConnectionSize filters = grailsApplication.config.dataSource.druid.filters } }
grails-app/conf/logback.groovy
添加日志配置
// 日志采集 logger('com.alibaba', DEBUG, ['STDOUT'], false)
启动项目,出现日志
2019-07-03 03:15:06.691 WARN --- [ main] com.alibaba.druid.pool.DruidDataSource : removeAbandoned is true, not use in productiion. 2019-07-03 03:15:07.078 INFO --- [ main] com.alibaba.druid.pool.DruidDataSource : {dataSource-1} inited Grails application running at http://localhost:8081 in environment: development
