springboot整合druid和配置资源监控

1.添加依赖,在maven repository中搜索

<dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid</artifactId>
            <version>1.1.21</version>
        </dependency>

2.配置application.yml

spring:
 datasource:
   username: root
   password: root
   url: jdbc:mysql://localhost:3306
   driver-class-name: com.mysql.jdbc.Driver
   type: com.alibaba.druid.pool.DruidDataSource
initialSize: 5
maxActive: 10
maxWait: 3000
maxIdle: 8
minIdle: 3

3.整合druid数据源

@Configuration
public class DruidConfig {
    @Bean
    public DataSource druid(){
        return new DruidDataSource();
    }
    //配置druid的监控
    //1、配置一个管理后台的servlet
    @Bean
    public ServletRegistrationBean statViewServlet(){
        ServletRegistrationBean bean = new ServletRegistrationBean(new StatViewServlet(),"druid/*");
        Map<String,String> initParames = new HashMap<>();
        initParames.put("loginUsername","admin");
        initParames.put("loginPassword","123456");
        initParames.put("allow","localhost");
        bean.setInitParameters(initParames);
        return bean;
    }
    //2、配置一个web监控的filter
    @Bean
    public FilterRegistrationBean webStatFilter(){
        FilterRegistrationBean bean = new FilterRegistrationBean();
        bean.setFilter(new WebStatFilter());
        Map<String,String> initParams = new HashMap<>();
        initParams.put("exclusion","*.js,*.css,/druid/*");
        bean.setInitParameters(initParams);
        bean.setUrlPatterns(Arrays.asList("/*"));
        return bean;
    }
}
