精通SpringBoot--整合druid监控SQL执行

咳咳，今天我们做些简单而实用的东西，使用springboot 整合alibaba的driud数据库监控工具。
alibaba已经提供了spring-boot-starter的jar包了。先看pom.xml加个依赖~~ (druid.version自己找哈) 。

<!--阿里巴巴druid数据库管理-->

  <dependency>

     <groupId>com.alibaba</groupId>

     <artifactId>druid-spring-boot-starter</artifactId>

     <version>${druid.version}</version>

  </dependency>

配置信息是少不了滴~~

# 开发环境下配置

spring:

  datasource:

    druid:

      url: jdbc:mysql://localhost:3306/test?allowMultiQueries:true&characterEncoding:UTF-8&zeroDateTimeBehavior:convertToNull

      username: root

      password: 123456

      driver-class-name: com.mysql.jdbc.Driver

      # 连接池配置

      initial-size: 1

      max-active: 20

      min-idle: 1

      max-wait: 10000

      pool-prepared-statements: true

      max-open-prepared-statements: 20

      validation-query: SELECT 1 FROM DUAL

      validation-query-timeout: 5000

      test-on-borrow: false

      test-on-return: false

      test-while-idle: true

      time-between-eviction-runs-millis: 60000

      min-evictable-idle-time-millis: 30000

      max-evictable-idle-time-millis: 60000

      removeAbandoned: true

      removeAbandonedTimeout: 1800

      connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000

      max-pool-prepared-statement-per-connection-size: 20

      filters: stat,wall #filters: #配置多个英文逗号分隔(统计，sql注入，log4j过滤)

    type: com.alibaba.druid.pool.DruidDataSource

接下来是重点，重点，重点......@Configuration注解的配置类

@Configuration

public class DruidConfig {

    private static final Logger logger = LoggerFactory.getLogger(DruidConfig.class);

    @Autowired

    private AppConfig appConfig;

    @Value("${spring.datasource.druid.url}")

    private String dbUrl;

    @Value("${spring.datasource.druid.username}")

    private String username;

    @Value("${spring.datasource.druid.password}")

    private String password;

    @Value("${spring.datasource.druid.driver-class-name}")

    private String driverClassName;

    @Value("${spring.datasource.druid.initial-size}")

    private int initialSize;

    @Value("${spring.datasource.druid.min-idle}")

    private int minIdle;

    @Value("${spring.datasource.druid.max-active}")

    private int maxActive;

    @Value("${spring.datasource.druid.max-wait}")

    private int maxWait;

    @Value("${spring.datasource.druid.time-between-eviction-runs-millis}")

    private int timeBetweenEvictionRunsMillis;

    @Value("${spring.datasource.druid.min-evictable-idle-time-millis}")

    private int minEvictableIdleTimeMillis;

    @Value("${spring.datasource.druid.validation-query}")

    private String validationQuery;

    @Value("${spring.datasource.druid.test-while-idle}")

    private boolean testWhileIdle;

    @Value("${spring.datasource.druid.test-on-borrow}")

    private boolean testOnBorrow;

    @Value("${spring.datasource.druid.test-on-return}")

    private boolean testOnReturn;

    @Value("${spring.datasource.druid.pool-prepared-statements}")

    private boolean poolPreparedStatements;

    @Value("${spring.datasource.druid.max-pool-prepared-statement-per-connection-size}")

    private int maxPoolPreparedStatementPerConnectionSize;

    @Value("${spring.datasource.druid.filters}")

    private String filters;

    @Value("{spring.datasource.druid.connection-properties}")

    private String connectionProperties;

    @Bean     //声明其为Bean实例

    @Primary  //在同样的DataSource中，首先使用被标注的DataSource

    public DataSource dataSource() {

        DruidDataSource datasource = new DruidDataSource();

        datasource.setUrl(dbUrl);

        datasource.setUsername(username);

        datasource.setPassword(password);

        datasource.setDriverClassName(driverClassName);

        //configuration

        datasource.setInitialSize(initialSize);

        datasource.setMinIdle(minIdle);

        datasource.setMaxActive(maxActive);

        datasource.setMaxWait(maxWait);

        datasource.setTimeBetweenEvictionRunsMillis(timeBetweenEvictionRunsMillis);

        datasource.setMinEvictableIdleTimeMillis(minEvictableIdleTimeMillis);

        datasource.setValidationQuery(validationQuery);

        datasource.setTestWhileIdle(testWhileIdle);

        datasource.setTestOnBorrow(testOnBorrow);

        datasource.setTestOnReturn(testOnReturn);

        datasource.setPoolPreparedStatements(poolPreparedStatements);

        datasource.setMaxPoolPreparedStatementPerConnectionSize(maxPoolPreparedStatementPerConnectionSize);

        try {

            datasource.setFilters(filters);

        } catch (Exception e) {

            logger.error("druid configuration initialization filter", e);

        }

        datasource.setConnectionProperties(connectionProperties);

        return datasource;

    }

    @Bean

    public ServletRegistrationBean druidServlet() {

        //logger.info("init Druid Servlet Configuration ");

        ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean();

        servletRegistrationBean.setServlet(new StatViewServlet());

        servletRegistrationBean.addUrlMappings("/druid/*");

        Map<String, String> initParameters = new HashMap<>();

        initParameters.put("loginUsername", appConfig.getDruidUserName());// 用户名

        initParameters.put("loginPassword", appConfig.getDruidPassword());// 密码

        initParameters.put("resetEnable", appConfig.getDruidResetAll());// 禁用HTML页面上的“Reset All”功能

        initParameters.put("allow", ""); // IP白名单 (没有配置或者为空，则允许所有访问)

        //initParameters.put("deny", "192.168.20.38");// IP黑名单 (存在共同时，deny优先于allow)

        servletRegistrationBean.setInitParameters(initParameters);

        return servletRegistrationBean;

    }

    @Bean

    public FilterRegistrationBean druidWebStatViewFilter() {

        FilterRegistrationBean registrationBean = new FilterRegistrationBean(new WebStatFilter());

        registrationBean.addInitParameter("urlPatterns", "/*");

        registrationBean.addInitParameter("exclusions", "*.js,*.gif,*.jpg,*.bmp,*.png,*.css,*.ico,/druid/*");

        return registrationBean;

    }

}

这里解释说下，AppConfig类是我自定义的一些配置项目，和集成druid没有关系噢。
到这就可以写个连接数据库查询测试下druid了，在地址栏输入localhost:8080/druid就能访问druid的登录页面了。
