IO錯誤：在部署JAR文件一段時間后，連接在Spring Boot中超時了嗎？

Question

我已經在我的server上部署了jar文件，該文件是從spring boot application創建的。 這樣我們就使用了embedded tomcat 。

我已經為此application在1- java類中設置了以下database configured ，

import org.apache.commons.dbcp.BasicDataSource;
    ...
    @Bean
    public DataSource dataSource() {
        //DriverManagerDataSource dataSource = new DriverManagerDataSource();
        BasicDataSource dataSource = new BasicDataSource();
        dataSource.setDriverClassName(environment.getRequiredProperty("spring.datasource.driverClassName"));
        dataSource.setUrl(environment.getRequiredProperty("spring.datasource.url"));
        dataSource.setUsername(environment.getRequiredProperty("spring.datasource.username"));
        dataSource.setPassword(environment.getRequiredProperty("spring.datasource.password"));
        dataSource.setMaxActive(10);
        dataSource.setMaxIdle(3);
        dataSource.setMaxWait(environment.getRequiredProperty("spring.datasource.tomcat.max-wait"));
        dataSource.setTestOnBorrow(environment.getRequiredProperty("spring.datasource.tomcat.test-on-borrow"));
        dataSource.setInitialSize(environment.getRequiredProperty("spring.datasource.tomcat.initial-size"));
        return dataSource;
    }

我注意到在部署最初的幾分鍾時。 工作正常。 但是經過一段時間后，會因以下錯誤而開始操作，

誰能指導我哪里出了問題？ 正是在programming side或在network side是這樣的issue ？

Answer 1

我認為引導正在為您配置DataSource。 您可以將以下內容添加到application.properties

spring.datasource.validation-query =選擇1

spring.datasource.test上借入=真

我將這些添加到我的配置中，並且可以正常工作。 請檢查。
