springboot读取自定义配置文件的list集合

1、新建自定义配置文件

文件名：opcaccess.yaml

 

 内容：

opc:
  accesslist:
    - Channel1.Device1.Tag1
    - Channel1.Device1.Tag2
    - Channel1.Device1.test
# 字段1 - test1 - 业务意义

pom.xml引入依赖：

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-configuration-processor</artifactId>
            <optional>true</optional>
        </dependency>

2、自定义配置文件对应的bean类

@Configuration
@ConfigurationProperties(prefix = "opc")
@PropertySource(value="classpath:opcaccess.yaml",ignoreResourceNotFound = false,factory = MyPropertySourceFactory.class)//配置文件路径
public class OpcAccessConfig {

    private List<String> accesslist;

    public List<String> getAccesslist() {
        return accesslist;
    }

    public void setAccesslist(List<String> accesslist) {
        this.accesslist = accesslist;
    }


}

3、新建工厂转换类PropertySourceFactory，把自定义配置文件.yml的读取方式变成跟application.yml的读取方式一致

public class MyPropertySourceFactory implements PropertySourceFactory {


    @Override
    public PropertySource<?> createPropertySource(String name, EncodedResource resource) throws IOException {
        return new YamlPropertySourceLoader().load(name,resource.getResource()).get(0);
    }
}

4、调用

public List<ResultBean> readPLCWithFile() throws Exception {
        // 1、获取配置文件中的待读取字段
        List<String> opcAccessList = opcAccessConfig.getAccesslist();
        List<ResultBean> resultBeans = opcUaService.readPLCWithFile(opcAccessList);
        for(ResultBean result : resultBeans){
            System.out.println(result);
        }
        return resultBeans;
    }
