Spring中URLEncoder.encode方法的功能简介说明

由于JDK中自带的URLEncoder.encode有bug 
      当对字符串进行URI编码时，会将空格编码为 ”+”号
      然而这是一个错误的编码结果，所以下文笔者将分享一种全新正确的操作方法,如下所示
=====================================================
     使用spring提供UriUtils中的encode 
    可将空格转换为%20

  
import java.io.UnsupportedEncodingException;
import java.net.URLEncoder;

import org.springframework.web.util.UriUtils;

public class MainTest {
	public static void main(String[] args) throws UnsupportedEncodingException {
		String encode = URLEncoder.encode("2024-05-12 00:00:00", "UTF-8");
        String decode = URLDecoder.decode("2024-05-12%2000%3A00%3A00", "UTF-8");
        String springEncode = UriUtils.encode("2024-05-12 00:00:00", "utf-8");
        String springDecode = UriUtils.decode("2024-05-12%2000%3A00%3A00", "utf-8");
        System.out.println("encode = " + encode);
        System.out.println("decode = " + decode);
        System.out.println("springEncode = " + springEncode);
        System.out.println("springDecode = " + springDecode);
   }
}


----运行以上代码，将输出以下信息-----

encode = 2024-05-12+00%3A00%3A00
decode = 2024-05-12 00:00:00
springEncode = 2024-05-12%2000%3A00%3A00
springDecode = 2024-05-12 00:00:00
