测试springMVC中的以对象形式接受前端传来的数据

首先建立POJO类

public class User {private String name;private Integer age;private Address address;public User() {// TODO Auto-generated constructor stub}public String getName() {return name;}public void setName(String name) {this.name = name;}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;}@Overridepublic String toString() {return "User [name=" + name + ", age=" + age + ", address=" + address+ "]";}}

User类中有个关联类Address

public class Address {private String province;private String city;public Address() {// TODO Auto-generated constructor stub}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;}@Overridepublic String toString() {return "Address [province=" + province + ", city=" + city + "]";}}

前端的表格代码

<form action="springmvc/testPojo" method="post">name:<input type="text" name="name" value="andy">age:<input type="text" name="age" value="12">province:<input type="text" name="address.province" value="hunan">city:<input type="text" name="address.city" value="cs"><input type="submit" ></form><br>

controller的调用

@Controller@RequestMapping("/springmvc")public class TestSpringMVC {private static final String SUCCESS = "success";@RequestMapping("/testPojo")public String testPojo(User user){System.out.println(user);return SUCCESS;}}

结果：

User [name=andy, age=12, address=Address [province=hunan, city=cs]]

测试总结：

如果想要前端数据自动封装到对象中，要有set、get方法，也要保持名字一致
