如何在 Spring xml 配置文件中初始化 Java Date 对象? [英] How to initialize a Java Date object in Spring xml configuration file?

问题描述

考虑这个简单的例子 -

Consider this simple example -

public class Person
 {
    private String name;
    private Date dateOfBirth;

    // getters and setters here...
 }

为了将Person初始化为Spring bean，我可以这样写.

In order to initialize Person as a Spring bean, I can write the following.

<bean id = "Michael" class = "com.sampleDomainName.Person">
<property name = "name" value = "Michael" />
</bean>

但是在上面的bean定义中，如何设置dateOfBirth?

But in the above bean definition, how can I set the dateOfBirth?

例如.我想将 dateOfBirth 设置为

For eg. I want to set the dateOfBirth as

1998-05-07

推荐答案

此处提到的答案之一很有用，但需要其他信息.需要提供 CustomDateEditor 的构造函数参数.

One of the answers mentioned here is useful, but it needs additional information. The constructor arguments for the CustomDateEditor need to be supplied.

<bean class="org.springframework.beans.factory.config.CustomEditorConfigurer">
  <property name="customEditors">
    <map>
      <entry key="java.util.Date"> <ref local = "customDateEditor" /> 
      </entry> 
    </map>
  </property> 
</bean>

<bean id = "customDateEditor" class="org.springframework.beans.propertyeditors.CustomDateEditor">
    <constructor-arg>
      <bean class="java.text.SimpleDateFormat">
          <constructor-arg value="yyyy-MM-dd" />
       </bean>
    </constructor-arg>
    <constructor-arg value="true" /> 
</bean>

现在可以了

<property name="dateOfBirth" value="1998-05-07" />
