Spring Boot 1.3.0 M4 发布，该版本主要是修复一些 bug 和一些改进，更新内容如下： Upgrading No special steps are required to upgrade from earlier Spring Boot 1.3 milestones. See the instructions in the M1 release notes for upgrade from 1.2.x. Cloudfoundry deployment regression Unfortunately, 1.3.0.M3 contains a property binding regression that prevents deployment of a Spring Boot application to CloudFoundry. This regression has been fixed. H2 auto-configuration The H2 auto-configuration feature introduced in 1.3.0.M3 was not enabled properly when spring-boot-devtools is available on the classpath. This has been fixed. New and Noteworthy Tip Check the configuration changelog for a complete overview of the changes in configuration. DataSource type The connection pool used by auto-configuration can now be specified via the spring.datasource.type configuration key. Internationalization The fallbackToSystemLocale flag of the auto-configured MessageSource instance can now be configured via the `spring.messages.fallback-to-system-locale- configuration key. 更多改进内容及下载地址请查看发行说明。 Spring Boot 项目旨在简化创建产品级的 Spring 应用和服务。你可通过它来选择不同的 Spring 平台。可创建独立的 Java 应用和 Web 应用，同时提供了命令行工具来允许 'spring scripts'. 下图显示 Spring Boot 在 Spring 生态中的位置： Spring Boot 1.3.0 M4 发布下载地址
