springboot druid sql 监控和 spring监控 无数据 问题解决 多数据源

1. sql 监控 无数据

#druid连接池
spring.datasource.type: com.alibaba.druid.pool.DruidDataSource
#最大活跃数
spring.datasource.maxActive: 20
#初始化数量
spring.datasource.initialSize: 1
#最大连接等待超时时间
spring.datasource.maxWait: 60000
#打开PSCache，并且指定每个连接PSCache的大小
spring.datasource.poolPreparedStatements: true
spring.datasource.maxPoolPreparedStatementPerConnectionSize: 20
#通过connectionProperties属性来打开mergeSql功能；慢SQL记录
#connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000
spring.datasource.minIdle: 1
spring.datasource.timeBetweenEvictionRunsMillis: 60000
spring.datasource.minEvictableIdleTimeMillis: 300000
spring.datasource.validationQuery: select 1 from dual
spring.datasource.testWhileIdle: true
spring.datasource.testOnBorrow: false
spring.datasource.testOnReturn: false
#配置监控统计拦截的filters，去掉后监控界面sql将无法统计,'wall'用于防火墙
filters: stat, wall, log4j

关键最后一句：filters: stat, wall, log4j

DruidConfiguration

/**
 * 说明：druid数据库连接池的配置类(必须与启动类包目录同级)
 * www.1b23.com
 */
@Configuration
public class DruidConfiguration {

	@Bean
	public ServletRegistrationBean<StatViewServlet> statViewServlet() {
		// 创建servlet注册实体
		ServletRegistrationBean<StatViewServlet> servletRegistrationBean = new ServletRegistrationBean<StatViewServlet>(new StatViewServlet(), "/druid/*");
		// 设置ip白名单
		//servletRegistrationBean.addInitParameter("allow", "127.0.0.1");
		// 设置ip黑名单，如果allow与deny共同存在时,deny优先于allow
		//servletRegistrationBean.addInitParameter("deny", "192.168.0.1");
		// 设置控制台管理用户
		//servletRegistrationBean.addInitParameter("loginUsername", "druid");
		//servletRegistrationBean.addInitParameter("loginPassword", "admin");
		// 是否可以重置数据
		servletRegistrationBean.addInitParameter("resetEnable", "false");
		return servletRegistrationBean;
	}

	@Bean
	public FilterRegistrationBean<WebStatFilter> statFilter() {
		// 创建过滤器
		FilterRegistrationBean<WebStatFilter> filterRegistrationBean = new FilterRegistrationBean<WebStatFilter>(new WebStatFilter());
		// 设置过滤器过滤路径
		filterRegistrationBean.addUrlPatterns("/*");
		// 忽略过滤的形式
		filterRegistrationBean.addInitParameter("exclusions", "*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*");
		return filterRegistrationBean;
	}
	
}

如果是多数据源的，需要配置

 @Bean(name = "masterDataSource")
    @Primary //www.1b23.com
    public DataSource masterDataSource() throws SQLException {
        DruidDataSource dataSource = new DruidDataSource();
        dataSource.setDriverClassName(driverClass);
        dataSource.setUrl(url);
        dataSource.setUsername(user);
        dataSource.setPassword(password);
        dataSource.addFilters("stat");
        dataSource.addFilters("wall");
        return dataSource;
    }

关键这两句；

        dataSource.addFilters("stat"); 
        dataSource.addFilters("wall");

2. spring 监控 无数据

加入配置类

package org.fh.config;

import org.springframework.aop.support.DefaultPointcutAdvisor;
import org.springframework.aop.support.JdkRegexpMethodPointcut;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Scope;

import com.alibaba.druid.support.spring.stat.DruidStatInterceptor;

/**
 * 说明：druid sring监控
 * www.fhadmin.org
 */
@Configuration
public class SpringDaoMethodAspect {

    @Bean
    public DruidStatInterceptor druidStatInterceptor() {
        DruidStatInterceptor dsInterceptor = new DruidStatInterceptor();
        return dsInterceptor;
    }

    @Bean
    @Scope("prototype")
    public JdkRegexpMethodPointcut druidStatPointcut() {
        JdkRegexpMethodPointcut pointcut = new JdkRegexpMethodPointcut();
        pointcut.setPattern("org.fh.mapper.*");//根据实际包名
        return pointcut;
    }

    @Bean
    public DefaultPointcutAdvisor druidStatAdvisor(DruidStatInterceptor druidStatInterceptor, JdkRegexpMethodPointcut druidStatPointcut) {
        DefaultPointcutAdvisor defaultPointAdvisor = new DefaultPointcutAdvisor();
        defaultPointAdvisor.setPointcut(druidStatPointcut);
        defaultPointAdvisor.setAdvice(druidStatInterceptor);
        return defaultPointAdvisor;
    }
}
