这篇文章主要介绍了springmvc如何使用pojo作为参数,文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下

springmvc会按请求参数名和pojo属性名进行匹配，自动为该对象填充属性值，支持级联属性。

user.java

package com.gong.springmvc.entities;

public class user {
  private string username;
  private string password;
  private string email;
  private integer age;
  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 integer getage() {
    return age;
  }
  public void setage(integer age) {
    this.age = age;
  }
  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 + ", age=" + age
        + ", address=" + address + "]";
  }
}

address.java

package com.gong.springmvc.entities;

public class address {
  private string city;
  private string street;
  public string getcity() {
    return city;
  }
  public void setcity(string city) {
    this.city = city;
  }
  public string getstreet() {
    return street;
  }
  public void setstreet(string street) {
    this.street = street;
  }
  @override
  public string tostring() {
    return "address [city=" + city + ", street=" + street + "]";
  }
  
}

springmvctest.java

import com.gong.springmvc.entities.user;

@requestmapping("/springmvc")
@controller
public class springmvctest {
  private static final string success = "success";
  
  @requestmapping(value="/testpojo")
  public string testpojo(user user) {
    system.out.println("testpojo:"+user);
    return success;
  }
}

index.jsp

<form action="springmvc/testpojo" method="post"><br>
    <span>username:</span><input type="text" name="username"><br>
    <span>password:</span><input type="password" name="password"><br>
    <span>email:</span><input type="text" name="password"><br>
    <span>age:</span><input type="text" name="password"><br>
    <span>city:</span><input type="text" name="address.city"><br>
    <span>street:</span><input type="text" name="address.street"><br>
    <input type="submit" value="submit"><br>
  </form>
