无法在 tomcat 8 中部署 spring 引导应用程序 (1.2.5) war

Question

我正在使用 spring-boot 1.2.5 开发一个网络应用程序，当我使用嵌入式 tomcat 生成 jar 文件时，该应用程序运行完美，但是当我需要生成一个war 文件并将其部署到 tomcat 我遇到了很多错误。

我遵循这个 instructions but no success. Here is the log 我尝试了不同的方法，但我仍然失败。非常欢迎任何帮助或建议。

这是我的申请class

@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

经过不同的方法，我发现了错误，这是我使用 Hikari CP 创建数据源的方式。如果您遇到类似问题，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);

并包括它

hc.setDataSourceProperties(dsProps);

我发现了这种方法，在我看来，它应该记录在 Spring 引导文档中
