SpringBoot整合Druid

一、引入jar

 <!--引入自定义数据源 https://mvnrepository.com/artifact/com.alibaba/druid -->
 <dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>druid</artifactId>
    <version>1.1.8</version>
</dependency>

二、全局配置文件中配置Druid

spring:
  datasource:
    username: root
    password: 123456
    url: jdbc:mysql://192.168.43.118:3307/jdbc
    driver-class-name: com.mysql.jdbc.Driver
    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,log4j
    maxPoolPreparedStatementPerConnectionSize: 20
    useGlobalDataSourceStat: true
    connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=500

加的独立属性会有警告提示没有对应的属性，需要重写数据源类注入到容器 

 

三、重写数据源类注入到容器 

/**

@Configuration
public class DruidConfig {
    @ConfigurationProperties("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","");//默认允许所有
        initParams.put("deny","192.168.43.182");
        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/*");//排除哪些请求
        bean.setInitParameters(initParams);
        bean.setUrlPatterns(Arrays.asList("/*"));
        return bean;

    }
}

三、测试是否整合成功 

1）、访问Druid主页

2）、登入查看
