springboot应用接入druid监控

1.引入druid

<dependency>
      <groupId>com.alibaba</groupId>
      <artifactId>druid</artifactId>
      <version>1.1.0</version>
 </dependency>

2.DuidConfig

import com.alibaba.druid.support.http.StatViewServlet;
import com.alibaba.druid.support.http.WebStatFilter;
import com.google.common.collect.Maps;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
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 java.util.HashMap;
import java.util.Map;

@Configuration
public class DruidConfig {
    private Logger logger = LoggerFactory.getLogger(DruidConfig.class);

    /**
     * Druid内置监控页面
     *
     * @return
     */
    @Bean
    public ServletRegistrationBean druidServlet() {
        logger.info("Init druid servlet configuration ");
        ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean();
        servletRegistrationBean.setServlet(new StatViewServlet());
        servletRegistrationBean.addUrlMappings("/druid/*");
        Map<String, String> initParameters = Maps.newHashMap();
         //登录查看信息的账号密码.
        initParameters.put("loginUsername", "druid");
        initParameters.put("loginPassword", "123456");
         //是否能够重置数据(禁用HTML页面上的“Reset All”功能)
        initParameters.put("resetEnable", "false");
        initParameters.put("allow", "");
        servletRegistrationBean.setInitParameters(initParameters);
        return servletRegistrationBean;
    }

     /**
     * 配置URI监控
     *
     * @return
     */
    @Bean
    public FilterRegistrationBean filterRegistrationBean() {
        FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean();
        filterRegistrationBean.setFilter(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;
    }

}
