Spring Boot 中的新功能。我正在尝试在 Tomcat (8.0.30) 服务器上运行 Spring Boot 应用程序。这是我的pom.xml：

我有一个 Spring Boot 应用程序。一切正常。我只是想了解事务管理器是如何工作的，因为我对我的应用程序有所怀疑。特别是，我对注释有点困惑。

这是Application.java（主类）：

@SpringBootApplication(exclude = ActiveMQAutoConfiguration.class)
@EnableScheduling
public class Application extends SpringBootServletInitializer
{

    @Override
    protected SpringApplicationBuilder configure (SpringApplicationBuilder builder) {
        return builder.sources(Application.class);
    }

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

}

配置类DataConfig.java如下所示：

@Configuration
@EnableTransactionManagement
@ComponentScan("com.pr.hotel")
@EnableJpaRepositories("com.pr.hotel")
@PropertySource("classpath:application.properties")
public class DataConfig
{
    // code
}

我很担心@EnableTransactionManagement。这个注释到底是什么意思呢？在这种情况下我应该使用@Transactional（我不）吗？

我是JavaScript和 JS 框架的新手。我有以下Vuejs代码片段：

    <div v-for="coefficient in coefficients" class="coefficient">
        <div>
            <span class="name">name:{{coefficient.name}}</span>
            <span class="value">value:{{coefficient.value}}</span>
            <span>---</span>
        </div>
    </div>

这是输出：

name: Ubuntu
value: 1
---
name: MacOS
value: 2
---
name: Windows
value: 3
---

如何排除coefficientsVuejs的最后一项？

我在JS代码中有这个数组:

var arrOf12Numbers = [10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120];

我需要将每个数字与之前的数字相加.

var cumulative12ArrOfNumbers = [10, 30, 60, 100, 150, 210, etc to 11 index... ];

JS中最好的方法是什么？
