Vue Axios Post delivery JavaBean to background __java

Front desk is vue+element, the background is spring boot set up the SSM project, now the demand is that the front form needs to pass the relevant Java bean to the background, because not familiar with the pure front and back end separation, so using the traditional jsp+vue+element

Through a variety of methods and Baidu, or 400 background parsing error, or passed the data are null, because the page other methods are used Axios, so do not want to use Ajax, and finally think of a curve to save the nation's way:

Idea: The foreground passes the JSON object, receives the JSON object in the background, converts the JSON object into a Java bean by Com.google.gson.Gson

Here are a few holes to notice:

1: Foreground data must be converted to JSON object Json.parse (Json.stringify (FormData))

2: Add head information:

headers:{' content-type ': ' Application/json;charset=utf-8 '}

3: Backstage with @requestbody receive

The following is the source code: marked red is the place to pay attention to

Front desk:

Editsubmit:function () {
Let Formdata=this.form;
formdata.role_id=this.role_id;

Let Admininfo=json.parse (Json.stringify (FormData));//need to be converted to a JSON object Axios.post (' ${ctx}/updateadmininfo ',
Admininfo,
{
headers:{
' Content-type ': ' Application/json;charset=utf-8 '/here plus head info
}
}
)
. Then (
function (params) {
if (params.data.code== ' C1000 ') {
this. $message. Success ("successful Renewal");
Reload data
}else{
this. $message. Error ("update failed");
}
})

},

Background:

@RequestMapping (value = "/updateadmininfo", method = requestmethod.post) public string Update (@RequestBody string AdminS TR) {
Gson gson= new Gson ();
Admininfo admin = Gson.fromjson (adminstr, Admininfo.class);

Related code implementation omitted

... return null, or be a very, very, very.

}

At present this method is feasible, just contact Vue, the other is not clear
