Question

我有一个包含Address对象的Person对象：

class Person {
   private int age;
   private Address address;

 public int getAge() {
    return age;
}

public void setAge(int age) {
    this.age = age;
}

public Address getAddress() {
    return address;
}

public void setAddress(Address address) {
    this.address= address;
}
}

一个班级地址：

class Address{

   private String streetAddress;
   private String city;

 public String getCity() {
    return city;
}

public void setCity(String city) {
    this.city = city;
}

public String getStreetAddress() {
    return state;
}

public void setStreetAddress(String streetAddress) {
    this.state = state;
}
}

在我的Spring网络流程中，我有：

<var name="person" class="Person"/>
<var name="address" class="Address"/>

   <view-state id="view1" view="qualificationView" model="person">

   <transition on="submitApplication" to="view2"/>
</view-state>

我的HTML有属性：

age
streetAddress
city

在表单提交上，我看到“age”属性被正确绑定，但是没有设置Address类中的属性。

如何设置所有字段？

Answer 1

<form:input type="text" path="address.streetAddress"/>

您不需要定义<var name="address".../>。我认为您必须在address至Person中明确初始化new Address()。
