springboot配置druid数据源及其监控

引入maven依赖

<dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
        </dependency>
        <!-- https://mvnrepository.com/artifact/com.alibaba/druid -->
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid</artifactId>
            <version>1.2.3</version>
</dependency>

在配置类中添加配置信息

@Configuration
public class MyDataSourceConfig {
    /**
     * 配置druid数据源
     *
     * @return
     */
    @ConfigurationProperties("spring.datasource")
    @Bean
    public DataSource dataSource() {
        DruidDataSource druidDataSource = new DruidDataSource();
        return druidDataSource;
    }

    /**
     * 配置druid的监控功能
     *
     * @return
     */
    @Bean
    public ServletRegistrationBean staViewServlet() {
        StatViewServlet statViewServlet = new StatViewServlet();
        ServletRegistrationBean<StatViewServlet> registrationBean = new ServletRegistrationBean<>(statViewServlet, "/druid/*");
        //配置监控页的登录账号和密码
        registrationBean.addInitParameter("loginUsername", "admin");
        registrationBean.addInitParameter("loginPassword", "123456");
        return registrationBean;
    }

    /**
     * webstatFilter用于采集wb-jdbc关联监控的数据
     */
    @Bean
    public FilterRegistrationBean webStatFilter() {
        WebStatFilter webStatFilter = new WebStatFilter();
        FilterRegistrationBean<WebStatFilter> filterFilterRegistrationBean = new FilterRegistrationBean<>(webStatFilter);
        //设置拦截的路径
        filterFilterRegistrationBean.setUrlPatterns(Arrays.asList("/*"));
        //设置发不拦截的请求路径
        filterFilterRegistrationBean.addInitParameter("exclusions", "*.js,*.gif,*.jpg,*.png,*.css,*.icon,/druid/*");
        return filterFilterRegistrationBean;
    }
}

测试：

@Slf4j
@RestController
@RequestMapping("/hello")
public class HelloController {
    @Autowired
    private JdbcTemplate jdbcTemplate;
    @GetMapping("/sql")
    public List<Map<String, Object>> testSql(){
        String sql="select * from tb_user";
        List<Map<String, Object>> list = jdbcTemplate.queryForList(sql);
        return list;
    }
}

在druid监控页面
