实体参数的接受
- 简单实体对象:请求参数名与形参属性对象名相同,定义pojo接受即可,将数据封装到实体类中
- 实体类代码如下:
-
package com.example.POJO; public class User { private String name; private Integer age; public String getName() { return name; } public void setName(String name) { this.name = name; } public void setAge(Integer age) { this.age = age; } public Integer getAge() { return age; } @Override public String toString() { return "User{" + "name='" + name + '\'' + ", age=" + age + '}'; } }
-
- 控制类代码如下:
-
package com.example.Controller; import com.example.POJO.User; import jakarta.servlet.http.HttpServletRequest; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestParam; import org.springframework.web.bind.annotation.RestController; // TODO 实体参数接受 @RequestMapping("/simplePojo") public String simplePojo(User user) { System.out.println(user); return "OK"; } }
-
- postman中发送请求、idea接受并处理请求结果如下:
-
复杂实体参数接受 (一个实体类中包含另一个实体类作为对象,即对象的组合)
-
参数的传递通过对象.属性=属性值的形式

package com.example.POJO; public class User { // TODO 对象的组合(一个实体类成员变量是另一个实体类的对象) private Address address; private String name; public Address getAddress() { return address; } public void setAddress(Address address) { this.address = address; } private Integer age; public String getName() { return name; } public void setName(String name) { this.name = name; } public void setAge(Integer age) { this.age = age; } public Integer getAge() { return age; } @Override public String toString() { return "User{" + "address=" + address + ", name='" + name + '\'' + ", age=" + age + '}'; } }
- Address
package com.example.POJO; 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 + '\'' + '}'; } }
