Json的格式规范

解决报错：
Resolved [org.springframework.web.HttpMediaTypeNotSupportedException: Content type ‘application/x-www-form-urlencoded;charset=UTF-8’ not supported]

$.ajax({
    type:"post",
     url:"/tproinfo/login",
     data:{
    	 "username":"username", 
    	 "password":"password"},
     success:function (result){
         console.log("返回的结果为：",result);
         if(result.code == "1"){
             alert("登录成功");
         }else {
             alert("登录失败");
         }
           }
       })

在以上代码中添加：contentType: "application/json;charset-UTF-8",可以解决。
完整代码如下：

$.ajax({
     contentType: "application/json;charset-UTF-8",
     type:"post",
     url:"/tproinfo/login",
     data:{
     	 "username":"username", 
    	 "password":"password"},
     success:function (result){
         console.log("返回的结果为：",result);
         if(result.code == "1"){
             alert("登录成功");
         }else {
             alert("登录失败");
         }
     }

 })

在解决上述问题后，运行再次报错：
Resolved [org.springframework.http.converter.HttpMessageNotReadableException: JSON parse error: Unrecognized token ‘username’: was expecting (JSON String, Number, Array, Object or token ‘null’, ‘true’ or ‘false’); nested exception is com.fasterxml.jackson.core.JsonParseException: Unrecognized token ‘username’: was expecting (JSON String, Number, Array, Object or token ‘null’, ‘true’ or ‘false’)at [Source: (PushbackInputStream); line: 1, column: 10]]

出现上述报错原因是Json中data数据格式不对，正确的Json格式为
data:'{"name":"zhangsan", "age":"18"}'

因此，最终的代码为：

$.ajax({
      contentType: "application/json;charset-UTF-8",
      type:"post",
      url:"/tproinfo/login",
      data:'{"username":"username", 
      		 "password":"password"}',
      success:function (result){
          console.log("返回的结果为：",result);
          if(result.code == "1"){
              alert("登录成功");
          }else {
              alert("登录失败");
          }
      }
  })
