SpringBoot整合Druid

1，配置application.yml

     spring:
          datasource:
            username: root
            password: 123456
            url: jdbc:mysql://localhost:3306/jdbcdb   #这是我的数据库jdbcdb
            driver-class-name: com.mysql.jdbc.Driver
            type: com.alibaba.druid.pool.DruidDataSource   #先导入pom文件中druid jar包
        
            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

2,配置druid

@Configuration
public class DruidConfig {

    @ConfigurationProperties(prefix = "spring.datasource")
    @Bean
    public DataSource druid(){
        return new DruidDataSource();
    }

    //配置Druid的监控
    //配置一管理后台的servlet
    @Bean
    public ServletRegistrationBean statViewServlet(){

        ServletRegistrationBean bean = new ServletRegistrationBean(new StatViewServlet(),"/druid/*");
        Map<String,String>initParams = new HashMap<>();
        initParams.put("loginUsername","admin");   //设置登陆账号密码
        initParams.put("loginPassword","123456");
        initParams.put("allow","");

        bean.setInitParameters(initParams);
        return  bean;
    }

    //配置管理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;
    }
}

3,一个测试类

先在数据库里面创建表department

@RestController
public class HelloController {

    @Autowired
    JdbcTemplate jdbcTemplate;

    @GetMapping("/hello")
    public Map<String,Object>map(){

        List<Map<String,Object>>list = jdbcTemplate.queryForList("select * from department");
        return list.get(0);
    }
}

4,访问 localhost:8080/druid/
