實(shí)體參數(shù)的接受

• 簡單實(shí)體對象：請求參數(shù)名與形參屬性對象名相同，定義pojo接受即可，將數(shù)據(jù)封裝到實(shí)體類中
• 實(shí)體類代碼如下：

  • 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 +
                    '}';
        }
    
    }
    

• 控制類代碼如下：
  • ?

    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 實(shí)體參數(shù)接受
        @RequestMapping("/simplePojo")
        public String simplePojo(User user) {
            System.out.println(user);
            return "OK";
        }
    }

• 復(fù)雜實(shí)體參數(shù)接受?（一個(gè)實(shí)體類中包含另一個(gè)實(shí)體類作為對象，即對象的組合）

  • 參數(shù)的傳遞通過對象.屬性=屬性值的形式

    • 

• 實(shí)體類的代碼如下：

  • User文章來源地址http://www.zghlxwxcb.cn/news/detail-565064.html

    package com.example.POJO;
    
    public class User {
        // TODO 對象的組合（一個(gè)實(shí)體類成員變量是另一個(gè)實(shí)體類的對象）
        private Address address;
        private String name;
    
        public Address getAddress() {
            return address;
        }
    
        public void setAddress(Address address) {
            this.address = address;
        }

  • Address

    package com.example.POJO;
    
    public class Address {
        private String province;
        private String city;
    
        public String getProvince() {

        public void setProvince(String province) {
            this.province = province;
        }
    
        public String getCity() {
            return city;
