springboot 加载自定义的属性配置文件 或者xml文件

1、properties  user.properties

2、xml  Pen1.xml

<?xml version="1.0" encoding="utf-8" ?>
<!DOCTYPE properties SYSTEM "http://java.sun.com/dtd/properties.dtd">
<properties>
    <entry key="color">red</entry>
    <entry key="length">100M</entry>
</properties>

3、code

package com.example.demo;

import org.springframework.core.io.UrlResource;
import org.springframework.core.io.support.PropertiesLoaderUtils;
import org.springframework.util.ResourceUtils;

import java.io.IOException;
import java.net.URL;
import java.util.Map;
import java.util.Properties;

public class Te {
    public static void main(String[] args) throws IOException {

        Properties properties = new Properties();
        URL url = ResourceUtils.getURL("classpath:user.properties");
        UrlResource resource = new UrlResource(url);
        PropertiesLoaderUtils.fillProperties(properties, resource);
        for (Map.Entry<Object, Object> entry : properties.entrySet()) {
            System.out.println(entry.getKey() + "=" + entry.getValue());
        }

        System.out.println("========================");
        URL url1 = ResourceUtils.getURL("classpath:Pen1.xml");
        UrlResource resource1 = new UrlResource(url1);
        PropertiesLoaderUtils.fillProperties(properties, resource1);

        for (Map.Entry<Object, Object> entry : properties.entrySet()) {
            System.out.println(entry.getKey() + "=" + entry.getValue());
        }


    }
}
