环境描述  
spring MVC 使用 @RequestBody 接收JSON参数转为实体对象

public void save(@RequestBody Scene scene, HttpServletRequest    
        request, HttpServletResponse response) throws Exception {

错误原因：  
当在浏览器中访问时 URL中带有特殊字符，如花括号冒号时，就会出现这个错误。  
例如：[http://localhost:8080/index.do][http_localhost_8080_index.do]?\{id:123\}  
解决方法：  
原因已经清楚了，但解决方法有多种：  
1、去除URL中的特殊字符；  
2、特殊字符是出现在后面跟的参数中，对参数进行 URL 编码，可以使用 JavaScript 中的 encodeURIComponent() 函数。  
3、使用 Post 方法提交数据  
以下两种方法参考：[http://blog.csdn.net/zeroso/article/details/70592179][http_blog.csdn.net_zeroso_article_details_70592179]  
4、更换低版本的Tomcat来规避这种问题。  
5、在 conf/catalina.properties 中最后添加一行：  
org.apache.tomcat.util.buf.UDecoder.ALLOW\_ENCODED\_SLASH=true  
重启服务器后，解决问题。

官方指南地址：[http://tomcat.apache.org/tomcat-8.5-doc/config/systemprops.html][http_tomcat.apache.org_tomcat-8.5-doc_config_systemprops.html]  
官方说明：  
org.apache.tomcat.util.buf.UDecoder.ALLOW\_ENCODED\_SLASH

If this is true ‘%2F’ and ‘%5C’ will be permitted as path.delimiters.If not specified, the default value of false will be used.
