使用spring DataBinder绑定对象属性

就是方便我们为对象设置属性，不需要一个一个的set，提高编程效率。

public class MyDataBinderBean {
    private String name;
    private int age;

    public String getName() {
        return name;
    }

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

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    @Override
    public String toString() {
        return JSON.toJSONString(this);
    }
}

public class MyMain {

    public static void main(String[] args) {
        MyDataBinderBean bean = new MyDataBinderBean();
        DataBinder dataBinder = new DataBinder(bean);
        // 设置无效
        dataBinder.setIgnoreInvalidFields(true);
        dataBinder.setIgnoreUnknownFields(true);
        Map properties = new HashMap<>();
        properties.put("name", "张三");
        properties.put("age", 60);
        MutablePropertyValues propertyValues = new MutablePropertyValues(properties);
        dataBinder.bind(propertyValues);
        System.out.println(bean);
    }
}

运行：

{"age":60,"name":"张三"}
