springboot项目使用druid
在这里插入图片描述
appriapplication.properties一部分配置
**appriapplication.properties一部分配置**

配置类
@Configuration

//@Slf4j
public class DruidConfig {

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

    @Bean
    public ServletRegistrationBean statViewServlet() {
        ServletRegistrationBean bean = new ServletRegistrationBean(new StatViewServlet(), "/druid/*");
        Map<String, String> initMap = new HashMap<>();
        initMap.put("loginUsername", "admin");
        initMap.put("loginPassword", "123456");
        initMap.put("allow", "");
        //initMap.put("deny","");
        //initMap.put("remoteAddress","");
        bean.setInitParameters(initMap);
        return bean;
    }

    @Bean
    public FilterRegistrationBean webStatFilter() {
        FilterRegistrationBean bean = new FilterRegistrationBean();
        //bean.setFilter(new WebStatFilter());
        bean.setFilter(new WebStatFilter());

        Map<String, String> initParams = new HashMap<>();
        initParams.put("exclusions", "*.js,*.css,/druid/*");
        initParams.put("sessionStatEnable", "false");
        bean.setInitParameters(initParams);
        bean.setUrlPatterns(Arrays.asList("/*"));
        return bean;
    }



    //使用@value注入配置文件中信息
    @Value("${spring.datasource.url}")
    private String dbUrl;

    @Value("${spring.datasource.username}")
    private String username;

    @Value("${spring.datasource.password}")
    private String password;


    @Value("${spring.datasource.driver-class-name}")
    private String driverClassName;

    @Value("${spring.datasource.filters}")
    private String filters;

    private static final Logger logger = LoggerFactory.getLogger(DruidConfig.class);
    @Bean
    public DataSource druidDataSource() throws Exception {
        DruidDataSource datasource = new DruidDataSource();
        datasource.setUrl(dbUrl);
        datasource.setUsername(username);
        datasource.setPassword(password);
        datasource.setDriverClassName(driverClassName);

        try {
            datasource.setFilters(filters);
        } catch (SQLException e) {
//            log.error("druid configuration initialization filter:{}",e);
            logger.error("druid configuration initialization filter:{}",e);
        }
        return datasource;
    }


}
