FactoryBean的用法之日期格式转换

public class Student {
    private Date birth;

    public void setBirth(Date birth) {
        this.birth = birth;
    }

    @Override
    public String toString() {
        return "Student{" +
                "birth=" + birth +
                '}';
    }
}

public class DateFactoryBean implements FactoryBean<Date> {

    private String strDate;

    public DateFactoryBean(String strDate) {
        this.strDate = strDate;
    }

    @Override
    public Date getObject() throws Exception {
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
        Date date = sdf.parse(strDate);
        return date;
    }

    @Override
    public Class<?> getObjectType() {
        return null;
    }
}

 <bean id="dateFactoryBean" class="com.powernode.spring6.bean.DateFactoryBean">
        <constructor-arg name="strDate" value="1998-08-05"/>
 </bean>

<bean id="student" class="com.powernode.spring6.bean.Student">
        <property name="birth" ref="dateFactoryBean"/>
</bean>
