How to inject string properties containing < character into Spring beans?
提问by Monika Michael
I have following bean definition for my DAO -
我的 DAO 有以下 bean 定义 -
<bean id="userDao" class="UserDao">
<property name="dataSource" ref="dataSource" />
<property name="queryPurgeInvalidReferrals" value="delete from reference where date < ?" />
</bean>
I am getting the error - The value of attribute "value" associated with an element type "property" must not contain the '<' character.
我收到错误 - 与元素类型“属性”关联的属性“值”的值不得包含“<”字符。

Since Spring config is an XML file, you need to escape <according to XML syntax:
由于 Spring config 是一个 XML 文件，所以需要<根据 XML 语法进行转义：
<property name="queryPurgeInvalidReferrals"
value="delete from reference where date < ?" />
