SpringBoot使用Druid数据源的配置方法

这篇文章主要介绍了SpringBoot使用Druid数据源的配置方法，文中代码实例相结合的形式给大家介绍的非常详细，需要的朋友参考下吧

Druid是阿里巴巴开源平台上一个数据库连接池实现，它结合了C3P0、DBCP、PROXOOL等DB池的优点，同时加入了日志监控，可以很好的监控DB池连接和sql的执行情况，可以说是针对监控而生的DB连接池(据说是目前最好的连接池)

一、依赖

为了测试，使用jdbcTemplate

org.springframework.bootspring-boot-starter-jdbccom.alibabadruid1.0.26MysqLmysql-connector-javaruntime

二、Druid配置

druid.properties #数据库设置 spring.datasource.driverClassName=com.MysqL.jdbc.Driver spring.datasource.url=jdbc:MysqL://localhost:3306/uu_core?useUnicode=true&characterEncoding=utf8&autoReconnect=true&useSSL=true spring.datasource.username=root spring.datasource.password=root #-------------------------- # 下面为连接池的补充设置，应用到上面所有数据源中 # 初始化大小，最小，最大 spring.datasource.initialSize=5 spring.datasource.minIdle=1 spring.datasource.maxActive=50 # 配置获取连接等待超时的时间 spring.datasource.maxWait=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.timeBetweenevictionRunsMillis=60000 # 配置一个连接在池中最小生存的时间，单位是毫秒 spring.datasource.minevictableIdleTimeMillis=300000 spring.datasource.validationQuery=SELECT 1 FROM DUAL spring.datasource.testWhileIdle=true spring.datasource.testOnBorrow=false spring.datasource.testOnReturn=false # 打开PSCache，并且指定每个连接上PSCache的大小 spring.datasource.poolPreparedStatements=false #spring.datasource.maxPoolPreparedStatementPerConnectionSize=20 # 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.filters=stat,wall,log4j # 通过connectProperties属性来打开mergesql功能；慢sql记录 spring.datasource.connectionProperties=druid.stat.mergesql=true;druid.stat.slowsqlMillis=5000 # 合并多个DruidDataSource的监控数据 #spring.datasource.useglobalDataSourceStat=true

三、实例化Druid Datasource

package cn.aduu.config; import com.alibaba.druid.pool.DruidDataSource; import com.alibaba.druid.support.http.StatViewServlet; import com.alibaba.druid.support.http.WebStatFilter; import org.springframework.boot.context.properties.ConfigurationProperties; import org.springframework.boot.web.servlet.FilterRegistrationBean; import org.springframework.boot.web.servlet.ServletRegistrationBean; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.context.annotation.PropertySource; import javax.sql.DataSource; /** * @author zh * @ClassName cn.aduu.config.DruidConfiguration * @Description */ @Configuration @PropertySource(value = "classpath:druid.properties") public class DruidConfiguration { @Bean(destroyMethod = "close", initMethod = "init") @ConfigurationProperties(prefix = "spring.datasource") public DataSource druidDataSource() { DruidDataSource druidDataSource = new DruidDataSource(); return druidDataSource; } /** * 注册一个StatViewServlet * @return */ @Bean public ServletRegistrationBean druidStatViewServlet(){ //org.springframework.boot.context.embedded.ServletRegistrationBean提供类的进行注册. ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(new StatViewServlet(),"/druid/*"); //添加初始化参数：initParams //白名单： servletRegistrationBean.addInitParameter("allow","127.0.0.1"); //IP黑名单 (存在共同时，deny优先于allow) : 如果满足deny的话提示:Sorry, you are not permitted to view this page. servletRegistrationBean.addInitParameter("deny","192.168.1.73"); //登录查看信息的账号密码. servletRegistrationBean.addInitParameter("loginUsername","admin"); servletRegistrationBean.addInitParameter("loginPassword","123456"); //是否能够重置数据. servletRegistrationBean.addInitParameter("resetEnable","false"); return servletRegistrationBean; } /** * 注册一个：filterRegistrationBean * @return */ @Bean public FilterRegistrationBean druidStatFilter(){ FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean(new WebStatFilter()); //添加过滤规则. filterRegistrationBean.addUrlPatterns("/*"); //添加不需要忽略的格式信息. filterRegistrationBean.addInitParameter("exclusions","*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*"); return filterRegistrationBean; } }

四、监控

访问 http://localhost:8080/druid， 使用上面配置的账号密码。

五、测试

@RestController public class HelloController{ private static final Logger logger = LoggerFactory.getLogger(HelloController.class); @Autowired private JdbcTemplate jdbcTemplate; @RequestMapping("hello") public List> hello() { List> list = jdbcTemplate.queryForList("SELECT user,password FROM MysqL.user ", new Object[]{}); return list; } }

访问 localhost:8080/hello

[ { "user": "root", "password": "*81F5E21E35407D884A6CD4A731AEBFB6AF209E1B" }, { "user": "root", "password": "*81F5E21E35407D884A6CD4A731AEBFB6AF209E1B" } ]
