Springboot 读取自定义yml 集合数据

1、通过启动类将自定义yml加载至spring容器

1、filter.yml

filter:
  nameList:
    张三,
    李四,
    王五

2、springboot启动类

import org.springframework.beans.factory.config.YamlPropertiesFactoryBean;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
import org.springframework.context.support.PropertySourcesPlaceholderConfigurer;
import org.springframework.core.io.ClassPathResource;

@SpringBootApplication
public class TestApplication {

public static void main(String[] args) {
    SpringApplication.run(TestApplication.class, args);
}

@Bean
public static PropertySourcesPlaceholderConfigurer properties() {
    //PropertySourcesPlaceholderConfigurer 引入外部属性文件
    PropertySourcesPlaceholderConfigurer configurer = new PropertySourcesPlaceholderConfigurer();
    //读取自定义配置的yml文件
    YamlPropertiesFactoryBean yaml = new YamlPropertiesFactoryBean();
    //多个
    //yaml.setResources(new ClassPathResource("filter.yml"),new ClassPathResource(""));
    //单个
    yaml.setResources(new ClassPathResource("filter.yml"));
    configurer.setProperties(yaml.getObject());
    return configurer;
}

}

3、新建FilterConfig

import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Configuration;
import org.springframework.stereotype.Component;

import java.util.List;

@Data
@Configuration
@ConfigurationProperties(prefix = “filter”)
public class FilterConfig {

public List<String> nameList;

}

4、测试

import com.zsh.test.config.FilterConfig;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;

@SpringBootTest
class TestApplicationTests {

@Autowired
public FilterConfig filterConfig;

@Test
void contextLoads() {
    filterConfig.getNameList().forEach(name-> System.out.println(name));
}

}
