我的数据库有有限的活动连接，这会导致hikaripool初始化异常，如下所示，我想忽略整个stacktrace并在我的主类中捕获异常。
以下是我的异常日志的堆栈跟踪：

2020-11-18 16:27:16.619  INFO 9124 --- [  restartedMain] com.zaxxer.hikari.HikariDataSource       : HikariPool-1 - Starting...

主要课程如下：

@SpringBootApplication(exclude = { DataSourceAutoConfiguration.class })
public class NseapiApplication {

    private static final Logger LOGGER = LoggerFactory.getLogger(NseapiApplication.class);

    private static String splunkUrl;

    @Value("${splunk.url}")
    public void setSplunkUrl(String splunkUrl) {
        NseapiApplication.splunkUrl = splunkUrl;
    }

    public static void main(String[] args) {
        SpringApplication.run(NseapiApplication.class, args);
        LOGGER.info("Forwarding logs to Splunk Cloud Instance : " + splunkUrl);

    }

    @Bean
    public static BeanFactoryPostProcessor dependsOnPostProcessor() {
        return bf -> {
            String[] jpa = bf.getBeanNamesForType(EntityManagerFactory.class);
            Stream.of(jpa).map(bf::getBeanDefinition).forEach(it -> it.setDependsOn("databaseStartupValidator"));
        };
    }

    @Bean
    public DatabaseStartupValidator databaseStartupValidator(DataSource dataSource) {
        DatabaseStartupValidator dsv = new DatabaseStartupValidator();
        dsv.setDataSource(dataSource);
        dsv.setValidationQuery(DatabaseDriver.MYSQL.getValidationQuery());
        return dsv;
    }
}

以下是数据库配置类：

@Configuration
public class DatasourceConfig {

    private static final Logger LOGGER = LoggerFactory.getLogger(DatasourceConfig.class);

    @Bean
    public DataSource datasource() {
        return DataSourceBuilder.create()
                    .driverClassName("com.mysql.cj.jdbc.Driver")
                    .url("jdbc:mysql://myDbUrl").username("myUserName").password("myPassword")
                    .build();

    }
}
