Spring Boot——Druid在application.yml文件中配置【spring.datasource.druid.aop-patterns】无效解决方案

# 问题描述 #

在使用aop-patterns配置的时候发现Spring监控无效

Druid版本：1.1.22

如果SpringBoot的配置使用的是properties文件，该配置正常。

如果使用yml作为配置文件，则该配置无效。

似乎不能以“-”作为分隔符。

使用了`ConditionalOnProperty`注解，该配置类并不会生效。

# 解决方案 #

方法一：重写DruidSpringAopConfiguration

如果我们想要使用`yml`文件，并且希望该配置生效，我们可以定义自己的配置文件，显示的注册相关的`bean`对象。

package com.jianggujin.love;
    
    import org.springframework.context.annotation.Configuration;
    import com.alibaba.druid.spring.boot.autoconfigure.properties.DruidStatProperties;
    import com.alibaba.druid.support.spring.stat.DruidStatInterceptor;
    import org.aopalliance.aop.Advice;
    import org.springframework.aop.Advisor;
    import org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator;
    import org.springframework.aop.support.RegexpMethodPointcutAdvisor;
    import org.springframework.beans.factory.annotation.Value;
    import org.springframework.boot.autoconfigure.condition.ConditionalOnProperty;
    import org.springframework.context.annotation.Bean;
    
    @Configuration
    public class DruidConfiguration{
    
        @Bean
        public Advice advice() {
            return new DruidStatInterceptor();
        }
    
        @Bean
        public Advisor advisor(DruidStatProperties properties) {
            return new RegexpMethodPointcutAdvisor(properties.getAopPatterns(), advice());
        }
    
        @Bean
        public DefaultAdvisorAutoProxyCreator advisorAutoProxyCreator() {
            DefaultAdvisorAutoProxyCreator advisorAutoProxyCreator = new DefaultAdvisorAutoProxyCreator();
            advisorAutoProxyCreator.setProxyTargetClass(true);
            return advisorAutoProxyCreator;
        }
    }

方法二：直接修改yml中aop-patterns字段为逗号分隔的字符串

修改yml中aop-patterns字段为逗号分隔的字符串，不要使用-符号的数组
