如何使用Spring Web Flow的

Question

我有一個包含一個Address對象像這樣的個人目標結合的複合模式：

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; 
} 
} 

和A類地址：

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 Web Flow的，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有屬性：

age 
streetAddress 
city 

在表單提交上，我看到「age」屬性正確綁定，但Address類中的屬性未被設置。

如何讓它設置所有的字段？

Answer 1

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

而且您不需要定義<var name="address".../>。我想你必須在Person到new Address()之間明確初始化address。
