我的项目是maven快速入门项目，我创建了两个类Employee & Address
提问于 2018-07-07 03:29:43
这是我的Employee类
package com.niit;公共类Employee {
private int employeeId;
private String name;现在如何在Address类中添加currentAddress和permanentAddress？
Address address;
public Address getAddress() {
return address;
}
public void setAddress(Address address) {
this.address = address;
}
public int getEmployeeId() {
return employeeId;
}
public void setEmployeeId(int employeeId) {
this.employeeId = employeeId;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}}
这是我的Address类
package com.niit;
public class Address {
private String Address;
private String City;
public String getAddress() {
return Address;
}
public void setAddress(String address) {
Address = address;
}
public String getCity() {
return City;
}
public void setCity(String city) {
City = city;
}
}这是我的Spring.xml文件
<bean id="Employee" class="com.niit.Employee">
<property name="Address" ref="Address"></property>
<property name="employeeId" value="101"></property>
<property name="name" value="abc"></property>
</bean>
<bean id="Address" class="com.niit.Address">
<property name="Address" value="whitefield"></property>
<property name="City" value="Banglore"></property>
</bean>

您可以在Employee实体中使用@Embeddded和@AttributeOverrides注释来完成此操作。
@Column(name=”ADDRESS”)
@Embedded
@AttributeOverrides({
@AttributeOverride(name=”street”, column=@Column(name=”CURRENT_STREET_NAME”)),
@AttributeOverride(name=”city”, column=@Column(name=”CURRENT_CITY_NAME”)),
@AttributeOverride(name=”state”, column=@Column(name=”CURRENT_STATE_NAME”)),
@AttributeOverride(name=”pincode”, column=@Column(name=”CURRENT_PIN_CODE”))})
private Address currentAddress;
@Embedded
private Address permanentAddress;类似的xml配置如下所示：
<attributes>
<id name="id">
<column name="fld_id"/>
<generated-value generator="generator" strategy="SEQUENCE"/>
<temporal>DATE</temporal>
<sequence-generator name="generator" sequence-name="seq"/>
</id>
<version name="version"/>
<embedded name="embeddedObject">
<attribute-override name"subproperty">
<column name="my_column"/>
</attribute-override>
</embedded>
<basic name="status" optional="false">
<enumerated>STRING</enumerated>
</basic>
<basic name="serial" optional="true">
<column name="serialbytes"/>
<lob/>
</basic>
<basic name="terminusTime" fetch="LAZY">
<temporal>TIMESTAMP</temporal>
</basic>
</attributes>注意:请根据您的需要修改此代码，因为这只是一个示例。
