SpringBoot项目去除druid监控的底部广告

Posted 2023-02-28 XiaoMaPro

说明

底部有广告,是因为其引入的druid包的中的upport\\http\\resources\\jscommon.js文件中包含了广告内容。

添加Druid的Starter依赖

• 对于SpringBoot项目.阿里druid有其专门的druid-spring-boot-starter版本，在这里我使用的是1.1.10版本，根据自己已经阿里更新的版本自行调整。

<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>druid-spring-boot-starter</artifactId>
    <version>1.1.13</version>
</dependency>

去除广告

• 在SpringBoot项目中编写一个RemoveDruidAdvertisingConfig配置类,去除druid监控页面广告

import java.io.IOException;

import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;

import org.springframework.boot.autoconfigure.AutoConfigureAfter;
import org.springframework.boot.autoconfigure.condition.ConditionalOnProperty;
import org.springframework.boot.autoconfigure.condition.ConditionalOnWebApplication;
import org.springframework.boot.web.servlet.FilterRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import com.alibaba.druid.spring.boot.autoconfigure.DruidDataSourceAutoConfigure;
import com.alibaba.druid.spring.boot.autoconfigure.properties.DruidStatProperties;
import com.alibaba.druid.util.Utils;

                chain.doFilter(request, response);
                response.resetBuffer();
                /**

                text = text.replaceAll("powered.*?shrek.wang</a>", "");
                response.getWriter().write(text);
            

            @Override
            public void destroy() 
            
        ;	
        FilterRegistrationBean registrationBean = new FilterRegistrationBean();
        registrationBean.setFilter(filter);
        registrationBean.addUrlPatterns(commonJsPattern);
        return registrationBean;
    

测试

• 重新启动项目,http://127.0.0.1:8080/druid/datasource.html可以看到其底部的广告已经没有了。
