1.1. 使用实体类接收请求参数 spring MVC 会按请求参数名和 实体类属性名进行自动匹配，自动为该对象填充属性值。支持级联属性。 [java] view plain copy @RequestMapping("/pojoParams") public String pojoParams(User user){ System.out.println(user); return "helloworld"; } User.Java: [java] view plain copy package com.ibigsea.springmvc.model; import java.io.Serializable; public class User implements Serializable { private static final long serialVersionUID = -5975751076183659876L; private String name; private int age; private Department department; public String getName() { return name; } public void setName(String name) { this.name = name; } public int getAge() { return age; } public void setAge(int age) { this.age = age; } public Department getDepartment() { return department; } public void setDepartment(Department department) { this.department = department; } @Override public String toString() { return "User [name=" + name + ", age=" + age + ", department=" + department + "]"; } } Department.java : [java] view plain copy package com.ibigsea.springmvc.model; import java.io.Serializable; public class Department implements Serializable { private static final long serialVersionUID = 6881984318733090395L; private Integer id; private String name; public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } @Override public String toString() { return "Department [id=" + id + ", name=" + name + "]"; } } JSP: [java] view plain copy

PoJo param

name: age: department id : department name :

运行结果: [plain] view plain copy User [name=bigsea, age=23, department=Department [id=1, name=test]]
