1.複雜的javabean

(1)javaBean

public class Spitter {

    private long id;
    @NotNull
    @Size(min = 5,max = 16,message = "{username.size}")
    private String username;
    @NotNull
    @Size(min = 5,max = 25,message = "{password.size}")
    private String password;
    @NotNull(message = "{firstName.null}"
 
)
    @Size(min=2,max=30,message = "{firstName.size}")
    private String firstName;
    @NotNull
    @Size(min=2,max=30,message = "{lastName.size}")
    private String lastName;

    public long getId() {
        return id;
    }

    public void setId(long id) {
        this.id = id;
    }

    public
 
 String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public
 
 String getFirstName() {
        return firstName;
    }

    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }

    public String getLastName() {
        return lastName;
    }

    public void setLastName(String lastName) {
        this.lastName = lastName;
    }
}

(2).controller

 @RequestMapping("/receive")
    public String receiveDate3(@RequestBody List<Spitter> spitters){
        System.out.println(spitters);
        return "redirect:/index.jsp";
    }

或

 @RequestMapping("/receive")
    public String receiveDate3(@RequestBody Spitter[] spitters){
        System.out.println(spitters);
        return "redirect:/index.jsp";
    }

(3).json格式

[
        {
            "id":"1",
            "firstName":"first1",
            "lastName":"last1",
            "username":"user1",
            "password":"pwd1"
        },
        {
            "id":"2",
            "firstName":"first2",
            "lastName":"last2",
            "username":"user2",
            "password":"pwd2"
        },
        {
            "id":"3",
            "firstName":"first3",
            "lastName":"last3",
            "username":"user3",
            "password":"pwd3"
        }
    ]

(4).前臺js 封裝json

        var spitters=[];
        for(var i=1;i<tr.length;i++){
            var spitter={};
            spitters.id=id;
            spitters.username=username;
            spitters.password=password;
            spitters.firstName=firstName;
            spitters.lastName=lastName;
            spitters.push(spitter);
        }

            //spring mvc接收陣列物件 要傳json 格式[{key:value,key,value},{key:value,key,value}]
             var json=JSON.stringify(spitters);

2.對於基本型別

(1).controller

@RequestMapping("/ids")
    public String receiveDate(int [] ids){
        System.out.println(ids);
        return "redirect:/index.jsp";
    }

(2)url

http://localhost:9091?ids=1&ids=2&ids=3

(3)

如果上述controller採用List<Integer>ids 作為引數，會報錯：
