使用Springboot配置druid

Love The Way You Lie 2022-06-03 05:29 242阅读 0赞

本人是maven项目:

**首先我们在pom.xml中添加Druid的依赖:**

<dependency>
        <groupId>com.alibaba</groupId>
        <artifactId>druid</artifactId>
        <version>1.1.5</version>
    </dependency>

**然后添加配置文件 配置文减的类要和运行方法的类在同一个目录下同个目录等级:**

package cn.et.lesson02;
    
    import java.util.ArrayList;
    import java.util.LinkedHashMap;
    import java.util.List;
    
    import org.springframework.boot.web.servlet.ServletRegistrationBean;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    
    import com.alibaba.druid.support.http.StatViewServlet;
    
    @Configuration
    public class ConfigBean {
    		/**
    		 * <bean di="druidStatView" class="cn.xxx.ServletRegistrationBean"/>
    		 * 
    		 * 
    		 * 
    		 * @return
    		 */
    	@Bean
    	public ServletRegistrationBean druidStatView(){
    		ServletRegistrationBean srb = new ServletRegistrationBean();
    		srb.setName("DruidStatView");
    		StatViewServlet svs = new StatViewServlet();
    		srb.setServlet(svs);
    		String url="/druid/*";
    		List<String>urls = new ArrayList<String>();
    		urls.add(url);
    		srb.setUrlMappings(urls);
    		LinkedHashMap<String, String> linkedHashMap = new LinkedHashMap<String, String>();
    		linkedHashMap.put("loginUsername", "admin");  //用户名
    		linkedHashMap.put("loginPassword", "123456"); //密码
    		srb.setInitParameters(linkedHashMap);
    		return srb;
    		
    	}
    }

**此类就想当与配置:**

<servlet>
            <servlet-name>DruidStatView</servlet-name>
            <servlet-class>com.alibaba.druid.support.http.StatViewServlet</servlet-class>
            <init-param>
                
                <param-name>loginUsername</param-name>
                <param-value>druid</param-value>
            </init-param>
            <init-param>
                
                <param-name>loginPassword</param-name>
                <param-value>druid</param-value>
            </init-param>
        </servlet>
        <servlet-mapping>
            <servlet-name>DruidStatView</servlet-name>
            <url-pattern>/druid/*</url-pattern>
        </servlet-mapping>

**必须要有一个主方法去启动服务:**

package cn.et.lesson02;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    
    //必须添加SpringBootApplication 启用spring的自动配置功能
    @SpringBootApplication
    public class Main {
    
    	/**
    	 * just run springboot启动的方法
    	 */
    	
    	public static void main(String[] args) {
    		//启动会加载自动配置 
    		 SpringApplication.run(Main.class, args);
    	} 
    }
