Javascript 415将json传递给java时不支持的格式
我需要将一个对象从JavaScript传递到Java控制器。我的做法如下：Javascript 415将json传递给java时不支持的格式,javascript,java,json,spring-mvc,Javascript,Java,Json,Spring Mvc,我需要将一个对象从JavaScript传递到Java控制器。我的做法如下： //java code @RequestMapping(value="/mailsend" , method=RequestMethod.POST) public int getBranchById(@RequestBody Modelmail details) throws IOException{ System.out.println(details); submitSuccess: function($for
//java code
@RequestMapping(value="/mailsend" , method=RequestMethod.POST)
public int getBranchById(@RequestBody Modelmail details) throws IOException{
System.out.println(details);
submitSuccess: function($form, event) {
event.preventDefault(); // prevent default submit behaviour
// get values from FORM
var name = $("input#name").val();
var email = $("input#email").val();
var phone = $("input#phone").val();
var message = $("textarea#message").val();
var firstName = name; // For Success/Failure Message
// Check for white space in name for Success/Fail message
if (firstName.indexOf(' ') >= 0) {
firstName = name.split(' ').slice(0, -1).join(' ');
}
var details={"name":name,"email":email,"phone":phone,"message":message}
//var obj = JSON.parse(details);
$.ajax({
url: "./mailsend",
type: "POST",
data: details,
cache: false,
success: function() {
}}
submitSuccess: function($form, event) {
event.preventDefault(); // prevent default submit behaviour
// get values from FORM
var name = $("input#name").val();
var email = $("input#email").val();
var phone = $("input#phone").val();
var message = $("textarea#message").val();
var firstName = name; // For Success/Failure Message
// Check for white space in name for Success/Fail message
if (firstName.indexOf(' ') >= 0) {
firstName = name.split(' ').slice(0, -1).join(' ');
}
var details={"name":name,"email":email,"phone":phone,"message":message}
//var obj = JSON.parse(details);
$.ajax({
url: "./mailsend",
type: "POST",
data: details,

success: function() {

submitSuccess: function($form, event) {

现在，我没有按照我的期望得到Java中的Java对象。任何帮助都将不胜感激。要修复4xx不受支持的媒体，您可以通过在app.properties中设置以下行来激活Spring日志：
submitSuccess: function($form, event) {
event.preventDefault(); // prevent default submit behaviour
// get values from FORM
var name = $("input#name").val();
var email = $("input#email").val();
var phone = $("input#phone").val();
var message = $("textarea#message").val();
var firstName = name; // For Success/Failure Message
// Check for white space in name for Success/Fail message
if (firstName.indexOf(' ') >= 0) {
firstName = name.split(' ').slice(0, -1).join(' ');
}
var details={"name":name,"email":email,"phone":phone,"message":message}
//var obj = JSON.parse(details);
$.ajax({
url: "./mailsend",
type: "POST",
data: details,
cache: false,
success: function() {
}}

激活Spring日志后，再次发出相关请求并检查日志输出以查看错误所在。要修复4xx不受支持的媒体，您可以通过将以下行设置为app.properties来激活Spring日志：

您的ajax函数不会发送json字符串，它将发送formdata，要以json字符串的形式发送数据，您需要将其转换为json字符串json.stringify（）。请尝试上面的注释，并在ajax查询中添加一个数据类型：“json”，以指定您在HeaderData中发送的内容：json.stringify（详细信息），数据类型：“json”，我添加了这两个东西，但仍然是same@user3273700您是对的，它将数据作为formdata发送，而应该作为有效负载发送，我想如何实现？您可以升级Modelmail类吗？您的ajax函数不会发送json字符串，而是发送formdata，要以json字符串的形式发送数据，需要将其转换为json字符串json.stringify（）。尝试上面的注释，并在ajax查询中添加一个数据类型：“json”，以指定在headersdata:json.stringify（详细信息），数据类型：“json”中发送的内容，我添加了这两个东西，但仍然是same@user3273700您是对的，它将数据作为formdata发送，而应该作为有效负载发送，我想如何实现这一点？？您可以升级您的Modelmail类吗？
