springmvc使用pojo和servlet原生api作为参数

一、Pojo作为参数：

实体：

package com.hy.springmvc.entities;
 
public class User {
 
    private String username;
 
    private String password;
 
    private String email;
 
    private Address address;
 
    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 getEmail() {
        return email;
    }
 
    public void setEmail(String email) {
        this.email = email;
    }
 
    public Address getAddress() {
        return address;
    }
 
    public void setAddress(Address address) {
        this.address = address;
    }
 
    @Override
    public String toString() {
        return "User [username=" + username + ", password=" + password
                + ", email=" + email + ", address=" + address + "]";
    }
 
}

package com.hy.springmvc.entities;
 
public class Address {
 
    private String province;
 
    private String city;
 
    public String getProvince() {
        return province;
    }
 
    public void setProvince(String province) {
        this.province = province;
    }
 
    public String getCity() {
        return city;
    }
 
    public void setCity(String city) {
        this.city = city;
    }
 
    @Override
    public String toString() {
        return "Address [province=" + province + ", city=" + city + "]";
    }
 
}

注解方法：

@RequestMapping("/testPojo")
    public String testPojo(User user) {
        System.out.println("testPojo :"+user);
        return SUCCESS;
    }

页面调用：

<form action="test/testPojo">
    username:<input name="username" type="text"><br>
    password:<input name="password" type="password"><br>
    email:<input name="email" type="text"><br>
    province:<input name="address.province" type="text"><br>
    city:<input name="address.city" type="text"><br>
    <input type="submit" value="submit">
</form>

支持级联属性

二、使用servlet原生api作为参数：

springmvc可以在映射方法中使用：

HttpServletRequest,

HttpServletResponse,

Writer,

InputStrream,

OutPutStream,

Locale

等作为参数。。
