Spring Boot采用了一种称为“约定优于配置”的理念,通过自动配置来减少手工配置的工作量。自动配置是Spring Boot的核心特性之一,当Spring Boot发现某个自动配置的条件成立时,它会自动启用对应的配置。 例如,当Spring Boot检测到项目中存在spring-boot-starter-data-jpa依赖时,会自动配置JPA相关的类,包括JpaTransactionMa...
Thepackageof theclassthatis annotated with@EnableAutoConfiguration, usually via@SpringBootApplication, has specific significance and is often used as a'default'. For example, it will be used when scanningfor@Entityclasses. It is generally recommended that you place@EnableAutoConfiguration(ifyou’re n...
When the debug mode is enabled, a selection of core loggers (embedded container, Hibernate and Spring Boot) are configured to output more information. Enabling the debug mode does not configure your application to log all messages withDEBUGlevel. 当启用调试模式时,配置选择的核心logger(嵌入式容器,...
springboot启动加载数据到redis 线上问题时,不得不仔细跑了很多遍Spring Boot的代码,于是整理一下,我用的是1.4.3.RELEASE。 首先,普通的入口,这没什么好说的,我就随便贴贴代码了: SpringApplication.run(Application.class, args); --> 1. 2. public static ConfigurableApplicationContext run(Object source, ...
Spring Boot自动配置会基于你添加的jar依赖试图自动配置你的Spring应用。例如,如果HSQLDB在你的classpath中,并且你没有手动的配置任何数据库连接beans,我们将会在自动配置一个内存中的数据库。 You need to opt-in to auto-configuration by adding the@EnableAutoConfigurationor@SpringBootApplicationannotations to one ...
Like Spring Data did, it would be nice for both Java and Kotlin developers to leverage in Spring Boot 2 null-safety annotations (@Nullable etc) in most common Spring Boot APIs like SpringApplication and TestRestTemplate. These annotation...

简介:SpringBoot2 | 条件注解 @ConditionalOnBean 原理源码分析(七) 条件注解是Spring4提供的一种bean加载特性,主要用于控制配置类和bean初始化条件。在springBoot,springCloud一系列框架底层源码中,条件注解的使用到处可见。 不少人在使用@ConditionalOnBean注解时会遇到不生效的情况,依赖的 bean 明明已经配置了,但就...
