  • SpringBoot整合德鲁伊数据源

    1.导入依赖

            <!--druid 依赖-->
            <dependency>
                <groupId>com.alibaba</groupId>
                <artifactId>druid-spring-boot-starter</artifactId>
                <version>1.1.9</version>
            </dependency>
    
    1. 修改配置文件
    datasource:
        driver-class-name: com.mysql.cj.jdbc.Driver
        url: jdbc:mysql://127.0.0.1:3306/cms?useSSL=false&serverTimezone=Asia/Shanghai
        username: root
        password: 123456
        type: com.alibaba.druid.pool.DruidDataSource
        #   数据源其他配置
        initialSize: 5
        minIdle: 5
        maxActive: 20
        maxWait: 60000
        timeBetweenEvictionRunsMillis: 60000
        minEvictableIdleTimeMillis: 300000
        validationQuery: SELECT 1 FROM DUAL
        testWhileIdle: true
        testOnBorrow: false
        testOnReturn: false
        poolPreparedStatements: true
        #   配置监控统计拦截的filters,去掉后监控界面sql无法统计,'wall'用于防火墙
        filters: stat,wall
        maxPoolPreparedStatementPerConnectionSize: 20
        useGlobalDataSourceStat: true
        connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=500
    
    1. 编写配置类
    package com.botao.cms.config;
    
    import com.alibaba.druid.pool.DruidDataSource;
    import com.alibaba.druid.support.http.StatViewServlet;
    import com.alibaba.druid.support.http.WebStatFilter;
    import org.springframework.boot.context.properties.ConfigurationProperties;
    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 javax.sql.DataSource;
    import java.util.Arrays;
    import java.util.HashMap;
    import java.util.Map;
    
    @Configuration
    public class DruidConfig {
        @ConfigurationProperties(prefix = "spring.datasource")
        @Bean
        public DataSource druid() {
            return new DruidDataSource();
        }
    
        //配置Druid的监控
        //1、配置一个管理后台的Servlet
        @Bean
        public ServletRegistrationBean statViewServlet() {
            ServletRegistrationBean bean = new ServletRegistrationBean(new StatViewServlet(), "/druid/*");
            Map<String, String> initParams = new HashMap<>();
    
            initParams.put("loginUsername", "admin");
            initParams.put("loginPassword", "123456");
            initParams.put("allow", "");
            //initParams.put("deny", "192.168.15.21");
    
            bean.setInitParameters(initParams);
            return bean;
        }
    
        //2、配置一个web监控的filter
        @Bean
        public FilterRegistrationBean webStatFilter() {
            FilterRegistrationBean bean = new FilterRegistrationBean();
            bean.setFilter(new WebStatFilter());
    
            Map<String, String> initParams = new HashMap<>();
            //放行静态文件和druid
            initParams.put("exclusions", "*.js,*.css,/druid/*");
            bean.setInitParameters(initParams);
            bean.setUrlPatterns(Arrays.asList("/*"));
            return bean;
        }
    
    }
