SpringMVC——5种类型参数传递

普通参数

解决，通过@RequestParam绑定

POJO类型参数

User

dart 复制代码

package com.baidu.domain;

public class User {

    private String name;
    private int age;


    public User() {
    }

    public User(String name, int age) {
        this.name = name;
        this.age = age;
    }

    /**
     * 获取
     * @return name
     */
    public String getName() {
        return name;
    }

    /**
     * 设置
     * @param name
     */
    public void setName(String name) {
        this.name = name;
    }

    /**
     * 获取
     * @return age
     */
    public int getAge() {
        return age;
    }

    /**
     * 设置
     * @param age
     */
    public void setAge(int age) {
        this.age = age;
    }

    public String toString() {
        return "User{name = " + name + ", age = " + age + "}";
    }
}

嵌套POJO类型参数

如果User中也有引用类型属性

dart 复制代码

package com.baidu.domain;

public class User {

    private String name;
    private int age;
    
    private Address address;


    public User() {
    }

    public User(String name, int age, Address address) {
        this.name = name;
        this.age = age;
        this.address = address;
    }

    /**
     * 获取
     * @return name
     */
    public String getName() {
        return name;
    }

    /**
     * 设置
     * @param name
     */
    public void setName(String name) {
        this.name = name;
    }

    /**
     * 获取
     * @return age
     */
    public int getAge() {
        return age;
    }

    /**
     * 设置
     * @param age
     */
    public void setAge(int age) {
        this.age = age;
    }

    /**
     * 获取
     * @return address
     */
    public Address getAddress() {
        return address;
    }

    /**
     * 设置
     * @param address
     */
    public void setAddress(Address address) {
        this.address = address;
    }

    public String toString() {
        return "User{name = " + name + ", age = " + age + ", address = " + address + "}";
    }
}
