无法在 tomcat 8 中部署 Spring Boot 应用程序（1.2.5）战争答案

【问题标题】：Not able to deploying spring boot app (1.2.5) war in tomcat 8无法在 tomcat 8 中部署 Spring Boot 应用程序（1.2.5）战争
【发布时间】：2015-10-03 22:08:25
【问题描述】：

我正在使用 spring-boot 1.2.5 做一个 web 应用程序，当我使用嵌入的 tomcat 生成 jar 文件时，该应用程序运行良好，但是当我需要生成一个 war 文件并将其部署到 tomcat 中时，我是得到大量错误。

我关注了这个instructions，但没有成功。这是log 我尝试了不同的方法，但我仍然失败了。非常欢迎任何帮助或建议。

这是我的应用类

@SpringBootApplication
public class MyApplication extends SpringBootServletInitializer {

@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(MyApplication.class);
    }

    public static void main(String[] args) throws Exception {
        SpringApplication.run(MyApplication.class, args);
    }
}

这是我的pom

【问题讨论】：

从您的日志来看，您正在使用一些自定义代码（而不是 Spring Boot 的自动配置）来创建和配置您的 Hikari 数据源。如果没有看到该代码，将很难找出问题所在。也许您可以分享一个重现问题的最小示例？

标签： java maven tomcat spring-boot hikaricp

【解决方案1】：

经过不同的方法后，我发现了错误，这就是我使用 Hikari CP 创建数据源的方式。如果您有类似的问题，请确保您的数据源配置如下所示：

@Bean(destroyMethod = "close")
public DataSource dataSource() {
    Properties dsProps = new Properties();
    dsProps.setProperty("url", url);
    dsProps.setProperty("user", username);
    dsProps.setProperty("password", password);

    HikariConfig hc = new HikariConfig();
    hc.setDriverClassName(driverClassName);
    hc.setJdbcUrl(url);
    hc.setMaxLifetime(maxLifetime);
    hc.setAutoCommit(autoCommit);
    hc.setConnectionTimeout(connectionTimeout);
    hc.setIdleTimeout(idleTimeout);
    hc.setMinimumIdle(minimumIdle);
    hc.setMaximumPoolSize(maximumPoolSize);
    hc.setPoolName(poolName);

    hc.setDataSourceProperties(dsProps);
    return new HikariDataSource(hc);
}

解决问题的部分是

    Properties dsProps = new Properties();
    dsProps.setProperty("url", url);
    dsProps.setProperty("user", username);
    dsProps.setProperty("password", password);

包括它

hc.setDataSourceProperties(dsProps);

我发现这种方法here，在我看来它应该记录在 Spring Boot 文档中

【讨论】：

或者，您可以使用hc.addDataSourceProperty(name, value)。
