上次介绍过一次Druid,不清楚可以查看:Spring Boot使用Druid和监控配置

编写Spring Boot自动配置类:DruidDataSourceconfig.java

package org.paascloud.ops.config;
import com.alibaba.druid.pool.DruidDataSource;
import org.springframework.boot.autoconfigure.condition.ConditionalOnClass;
import org.springframework.boot.autoconfigure.condition.ConditionalOnProperty;
import org.springframework.boot.autoconfigure.jdbc.DataSourceProperties;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
/**
 * Created by meyer on 2017/1/15.
 */
@Configuration
@ConditionalOnClass({DruidDataSource.class})
@ConditionalOnProperty(
        name = {"spring.datasource.type"},
        havingValue = "com.alibaba.druid.pool.DruidDataSource",
        matchIfMissing = true
)
@EnableConfigurationProperties(DruidDataSourceProperties.class)
public class DruidDataSourceConfig {
    @Bean
    public DruidDataSource dataSource(DataSourceProperties dataSourceProperties, DruidDataSourceProperties druidDataSourceProperties) {
        DruidDataSource druidDataSource = (DruidDataSource) dataSourceProperties.initializeDataSourceBuilder().type(DruidDataSource.class).build();
        druidDataSource.configFromPropety(druidDataSourceProperties.toProperties());
        druidDataSource.setInitialSize(druidDataSourceProperties.getInitialSize());
        druidDataSource.setMinIdle(druidDataSourceProperties.getMinIdle());
        druidDataSource.setMaxActive(druidDataSourceProperties.getMaxActive());
        druidDataSource.setMaxWait(druidDataSourceProperties.getMaxWait());
        druidDataSource.setConnectProperties(druidDataSourceProperties.getConnectionProperties());
        return druidDataSource;
    }
    @Bean
    public ServletRegistrationBean druidStatViewServlet(DruidDataSourceProperties druidDataSourceProperties) {
        if (StringUtils.isEmpty(druidDataSourceProperties.getServletPath())) {
            druidDataSourceProperties.setServletPath("/druid/*");
        }
        return new ServletRegistrationBean(new StatViewServlet(), druidDataSourceProperties.getServletPath());
    }
    @Bean
    public FilterRegistrationBean druidWebStatFilter() {
        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,/druid2/*");
        return filterRegistrationBean;
    }
}

触发Druid配置:

spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://xxxxx:3306/xxxxxx
spring.datasource.username=xxxxxxxx
spring.datasource.password=xxxxxxxxxxxx

后续介绍Druid怎么配合spring-boot-starter-actuator来获取监控数据.
