環境描述
spring MVC 使用 @RequestBody 接收JSON引數轉為實體物件
public void save(@RequestBody Scene scene, HttpServletRequest request, HttpServletResponse response) throws Exception { }
錯誤原因:
當在瀏覽器中訪問時 URL中帶有特殊字元,如花括號冒號時,就會出現這個錯誤。
例如:http://localhost:8080/index.do?{id:123}
解決方法:
原因已經清楚了,但解決方法有多種:
1、去除URL中的特殊字元;
2、特殊字元是出現在後面跟的引數中,對引數進行 URL 編碼,可以使用 JavaScript 中的 encodeURIComponent() 函式。
3、使用 Post 方法提交資料
4、更換低版本的Tomcat來規避這種問題。
5、在 conf/catalina.properties 中最後新增一行:
org.apache.tomcat.util.buf.UDecoder.ALLOW_ENCODED_SLASH=true
重啟伺服器後,解決問題。
官方說明:
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.
