Question

我在前端使用了Backbone模型，模型URL为'Student'，后端使用Spring Controller。

我可以使用以下代码进行提取

@RequestMapping(value = "/Student", produces = "application/json", method = RequestMethod.GET)
public @ResponseBody Student createStudent() {
    Student student = new Student("Abc","Def");
    return student;
}

但以下保存代码无效

@RequestMapping(value = "/Student", consumes = "application/json", produces =  "application/json",method = RequestMethod.POST)
public @ResponseBody Student saveStudent(@RequestBody Student student) {
    System.out.println(student.getName());
    return student;
}

我在客户端更改了Student的一些属性并保存但是它给出了我的HTTP 400错误描述“客户端发送的请求在语法上是不正确的。”

骨干模型

var Student = Backbone.Model.extend({
    url : 'Student',
    defaults : {
        name : '',
        address : '',
    }
});

var student = new Student();
student.fetch();
alert(JSON.stringify(student,null,4));
student.set({name:'john'});
student.save();

学生班

public class Student{
    private String name;
    private String address;

    public void Student(String name,String address){
       this.name=name;
       this.address=address;
    }

    public String getName(){
       return name;
    }

    public void setName(String name){
        this.name=name;
    }

    public String getAddress(){
       return address;
    }

    public void setAddress(String address){
        this.address=address;
    }
}

更新：问题是弹簧控制器的saveStudent（）方法中JSON转换为学生对象的错误，同时接受给出400错误的@RequestBody参数。我通过在Student类中添加一个空的默认构造函数Student（）并向Backbone save方法添加null来解决我的问题。

在学生班上

public Student(){
}

骨干保存

student.save(null,{
    success:function()
    {
        ...
    }
);

Backbone模型保存，后端的Spring Controller无法正常工作
