我有一个使用 spring-boot 1.2.7 部署到使用 Java 8 的 Tomcat 8 的 Spring Boot 服务。该服务在 Tomcat 服务器重新启动时运行良好，但在取消部署并重新部署后，我收到“数据源已关闭”错误。

更新这确实适用于 tomcat 7 java 7。 大家好，我创建了一个简单的示例应用程序，该应用程序出现错误并在此处使用 H2 jndi 数据源。 https://github.com/dstrimble/ws_preRatesFilter 我已将 tomcat 配置文件放在项目基础目录中

我在外部 Tomcat 服务上使用 JNDI 数据源，而不是嵌入的。

Spring Framework 有一个在 4.2 发布行中得到修复的问题。基本上，如果 bean 实现Closeable了它的关闭/关闭方法，即使destroyMethod被禁用（如 Spring Boot 那样）也会被调用。

它与 Tomcat7 而不是 8 一起工作的原因可能是由于 tomcat8 使用了一些新的语言特性（AutoCloseable）。当部署在 Tomcat8 上时，DataSource实现了这个额外的接口，并且由于 bug，调用了 shutdown 方法。

您现在可以将 Spring Framework4.2.2.RELEASE与 Spring Boot 1.2.x 一起使用以从该修复中受益。升级到 Spring Boot 1.3 将允许您以标准方式修复该错误。

同时，只需添加，<spring.version>4.2.2.RELEASE</spring.version>因为您正在spring-boot-starter-parent项目中使用。

如果您无法更新到 Spring Framework 4.2.x，另一种解决方案是为数据源提供包装器。就像是

    @Bean
    public DataSource getJndiDataSource() {
        try {
            JndiTemplate jndiTemplate = new JndiTemplate();
            DataSource ds = (DataSource) jndiTemplate.lookup("java:comp/env/"+JNDI_DATASOURCE);
            return new DelegatingDataSource(ds);
        } catch(NamingException e){
            LOG.error("Could not find JNDI data source (java:comp/env/):"+JNDI_DATASOURCE, e);
            return null;
        }
    }

委托数据源不是 AutoClosable 的，因此不会被 Spring Framework 关闭。
