1、配置类(Configuration Classes) 1.1、导入其他的 Configuration Classes 1.2、导入 xml 配置 2、自动配置(Auto-configuration) 2.1、逐步替换自动配置 2.2、如何关闭特定的 Auto-configuration Classes 3、参考 1、配置类(Configuration Classes) Spring Boot 支持基于 xml 的配置,但更偏向于使用基于 Java 的配置,通常...
Auto-configurations must be loaded that way only. Make sure that they are defined in a specific package space and that they are never the target of component scanning. Furthermore, auto-configuration classes should not enable component scanning to find additional components. 简单来说就是Auto-config...

In this quick tutorial, we’ll discuss how to exclude auto-configuration classes from Spring Boot tests. Spring Boot’s auto-configuration feature is very handy, as it takes care of a lot of setup for us. However, this can also be an issue during testing if we don’t want a certain ...

This is an expansion of #15750. There are a number of places in Boot's auto-configuration where a dependency is injected into a configuration class's constructor and then only used in a single @Bean method. This is inefficient when the @...

无论是basePackageClasses()或basePackages()可以定义特定的软件包进行扫描。如果未定义特定包,则将从声明此注解的类的包进行扫描。 3.自定义自动配置 要创建自定义自动配置,我们需要创建一个注释为@Configuration的类并注册它。 让我们为MySQL数据源创建自定义配置: ...
