### 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！");
    	}
    }
