2.读取动态拼接key的配置文件属性值

0.要读取的配置文件

server:
  port: 8999

hc:
  test1: test1111
  test2: test2222

1.通过Environment读取

  @Autowired
    private Environment env;

    
    @RequestMapping("/read1")
    public String readYml1(int i) {
        String property = env.getProperty("hc.test"+i);
        return property;
    }

2.封装相关工具类

   
    @RequestMapping("/read")
    public String readYml(int i) {
        String property = EnvironmentUtil.getProperty("hc.test"+i);
        return property;
    }

import org.springframework.core.env.Environment;

public class EnvironmentUtil {
    public static Environment environment = SpringUtil.getBean(Environment.class);

    public static String getProperty(String key) {
        return environment.getProperty(key);
    }
}

import org.springframework.beans.BeansException;
import org.springframework.beans.factory.config.BeanFactoryPostProcessor;
import org.springframework.beans.factory.config.ConfigurableListableBeanFactory;
import org.springframework.stereotype.Component;

@Component
public final class SpringUtil implements BeanFactoryPostProcessor {
    
    private static ConfigurableListableBeanFactory beanFactory;

    @Override
    public void postProcessBeanFactory(ConfigurableListableBeanFactory beanFactory) throws BeansException {
        SpringUtil.beanFactory = beanFactory;
    }
    
    public static  T getBean(Class clz) throws BeansException {
        T result = (T) beanFactory.getBean(clz);
        return result;
    }
}
