SpringBoot读取配置文件（从classpath/file读取yml/properties文件)

Posted 2020-11-03 gossip

一、读取properties文件

使用配置项@PropertySource

 

二、读取yml文件

启动类添加下面代码：

 
@Bean
public static PropertySourcesPlaceholderConfigurer properties() {
    PropertySourcesPlaceholderConfigurer configurer = new PropertySourcesPlaceholderConfigurer();
    YamlPropertiesFactoryBean yaml = new YamlPropertiesFactoryBean();
    yaml.setResources(new FileSystemResource("/dir/application.yml"));//File引入
    //yaml.setResources(new ClassPathResource("application.yml"));//class引入
    configurer.setProperties(yaml.getObject());
    return configurer;
}
 

 

1、引入多个配置文件：yaml.setResources(new ClassPathResource("application1.yml"), new ClassPathResource("application2.yml"));
