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")@Controllerpublic 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>

启动tomcat服务器之后：

输入相应信息点击提交：

成功为pojo赋值，包括级联属性address。
