我面临一个非常奇怪的问题。我正在尝试通过 PropertyPlaceholderConfigurer 类配置在我的 spring applicationcontext.xml 文件中声明的数据源的属性。应用程序上下文文件如下所示:-
<?xml version="1.0" encoding="UTF-8"?>

<bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">

</bean>
</beans>
我也尝试过使用 context:property-placeholder 标签,但它似乎没有任何效果。上面提到的属性文件也成功部署在 WEB-INF/classes 目录下。
由于某种原因,spring 容器能够加载属性文件(使用无效属性文件检查并引发 FNF 异常),但不能用它们的值替换属性占位符。
我正在使用一个 tomcat 7 WS,CATALINA.BASE 指向我的运行时。以前有人遇到过这个问题吗?有什么解决办法吗?
