Java重定向报错：java.lang.IllegalArgumentException: The Unicode character [测] at code point [27,979] …

一、场景

控制器重定向时报错

二、控制器

@Slf4j
@RestController
public class RedirectTestController {

	@RequestMapping("/redirectTest")
	public ModelAndView redirectTest() {
		String mainUrl = "redirect:"
                + "https://www.xxx.com.cn/xxxApp/#/Index?id=1&userName=测试1005&workNo=1005&isSystem=0";

		return new ModelAndView(mainUrl);
	}
}

三、报错信息

四、原因

url出现没有经过编码的中文

五、解决

使用URLEncoder.encode()对url中文参数进行编码

@RequestMapping("/redirectTest")
public ModelAndView redirectTest() {
	try {
		String mainUrl = "redirect:"
			+ "https://www.xxx.com.cn/xxxApp/#/Index?id=1&userName=" + URLEncoder.encode("测试1005", "UTF-8") + "&workNo=1005&isSystem=0";
            
		return new ModelAndView(mainUrl);
	} catch (UnsupportedEncodingException e) {
		log.error("URL编码出现异常：" + e.getMessage(), e);
		throw new RuntimeException("URL编码出现异常！");
	}
}
