SpringBoot 实体参数(用于请求参数比较多时使用)

字段必须和传参时一致，否则为null，
使用AIT+INS可以快速生成，SET GET方法

public class User {

	//字段必须和传参时一致，否则为null
    private String user;
    private String password;

    public String getUser() {
        return user;
    }

    public void setUser(String user) {
        this.user = user;
    }

    public String getPassword() {
        return password;
    }

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

    @Override
    public String toString() {
        return "User{" +
                "user='" + user + '\'' +
                ", password='" + password + '\'' +
                '}';
    }
}

复杂嵌套参数

两个类 现将两个类合并对象，返回前端，把Update封装到User

User

public class User {

    private String user;
    private String password;
    private Update up;

    public Update getUp() {
        return up;
    }

    public void setUp(Update up) {
        this.up = up;
    }

    public String getUser() {
        return user;
    }

    public void setUser(String user) {
        this.user = user;
    }

    public String getPassword() {
        return password;
    }

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

    @Override
    public String toString() {
        return "User{" +
                "user='" + user + '\'' +
                ", password='" + password + '\'' +
                ", up=" + up +
                '}';
    }
}

Update

public class Update {

    private  String time;
    private  int num;

    public String getTime() {
        return time;
    }

    public void setTime(String time) {
        this.time = time;
    }

    public int getNum() {
        return num;
    }

    public void setNum(int num) {
        this.num = num;
    }


    @Override
    public String toString() {
        return "Update{" +
                "time='" + time + '\'' +
                ", num=" + num +
                '}';
    }
}

前端给Update time 和 num 传值
