  • springboot整合druid连接池

    • 使用springboot默认的连接池

    • 导入springboot data-jdbc依赖

            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-data-jdbc</artifactId>
            </dependency>
    • 配置文件配置连接池

    spring:
      datasource:
        username: root
        password: 5201314
        url: jdbc:mysql:///jqmb?serverTimezone=UTC
        driver-class-name: com.mysql.cj.jdbc.Driver
    • springboot默认的连接池

    @Autowired
          DataSource dataSource;
        @Test
        void contextLoads() {
            System.out.println(dataSource.getClass());
            System.out.println("____________________________________");
        }

    •  使用连接池druid

    • 导入druid依赖

    <dependency>
                <groupId>com.alibaba</groupId>
                <artifactId>druid</artifactId>
                <version>1.0.18</version>
            </dependency>
    • 配置文件配置druid的属性

    spring:
      datasource:
        username: root
        password: 5201314
        url: jdbc:mysql:///jqmb?serverTimezone=UTC
        driver-class-name: com.mysql.cj.jdbc.Driver
        type: com.alibaba.druid.pool.DruidDataSource
        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
        filters: stat,wall,log4j
        maxPoolPreparedStatementPerConnectionSize: 20
        useGlobalDataSourceStat: true
        connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=500

    • 配置类中对druid属性进行绑定

    @Configuration
    public class DataSource_Druid_Configure {
    
        @ConfigurationProperties(prefix = "spring.datasource")
        @Bean
        public DruidDataSource getDataSour(){
            return new DruidDataSource();
        }

    • 配置Druid的监控后台

     //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");//登录用户名
            initParams.put("loginPassword","123456");//登录密码
            initParams.put("allow","");//默认就是允许所有访问
            initParams.put("deny","192.168.15.21");//拒绝访问
    
            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<>();
            initParams.put("exclusions","*.js,*.css,/druid/*");
            bean.setInitParameters(initParams);
            bean.setUrlPatterns(Arrays.asList("/*"));
    
            return  bean;
        }
    •  访问http://localhost:8090/druid/login.html

    •  如果sql监控失效需要导入log4j 依赖

       <dependency>
                <groupId>log4j</groupId>
                <artifactId>log4j</artifactId>
                <version>1.2.17</version>
            </dependency>
