title: Spring boot Unexpected character % code 37
body: <p>I am trying to read a string type attribute which contains json type data:</p>
  <p>code react js :</p>
  <pre><code>axios.post(&quot;http://localhost:8080/MenuFiltre/filtreregioncloser&quot;,JSON.stringify(FilterRegion))
  </code></pre>
  <p>code spring boot :</p>
  <pre><code>@PostMapping(&quot;/filtreregioncloser&quot;)
      public Iterable&lt;Closerfprfx&gt;gettab1(@RequestBody String filterRegion) throws JsonMappingException, JsonProcessingException
      {
          
      ObjectMapper mapper = new ObjectMapper();
      FilterRegionOne fro = mapper.readValue(filterRegion, FilterRegionOne.class);
      
  
          
          System.out.println(fro.isRfx());
  
           return null;      
      }
  </code></pre>
  <p>but when I try to display data in the console I got this error</p>
  <pre><code>com.fasterxml.jackson.core.JsonParseException: Unexpected character ('%' (code 37)): expected a valid value (JSON String, Number, Array, Object or token 'null', 'true' or 'false')
