我正在使用 Spring 3.1.1.RELEASE。在我的应用程序上下文中，我正在尝试使用基于属性文件中的属性的构造函数来设置 bean。这是我的应用程序上下文...

    <!-- Define test properties  -->
    <util:properties id="applicationProperties" location="classpath:test.properties" />

    <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
            <property name="locations">
                    <list>
                            <value>classpath:test.properties</value>
                    </list>
            </property>
            <property name="ignoreUnresolvablePlaceholders" value="false"/>
    </bean>

    <bean id="myprojectClient" class="org.mainco.subco.myproject.myprojectClient">
    <constructor-arg value="${quickbase.username}" />
    <constructor-arg value="${quickbase.password}" />
</bean>

以及我的 test.properties 文件的顶部……</p> 

# Quickbase credentials
quickbase.username=dalvarado-NONEMP@mainco.org
# It is expected that the password given here is encrypted.
quickbase.password=o37AbCdju57/nTWplI0oNg==

这是我在 JUnit 测试中声明应用程序上下文文件的方式...

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({ "classpath:test-context.xml" })
public class TrainingAssignmentDaoTest extends AbstractTransactionalJUnit4SpringContextTests {

…

    @Autowired
    @Qualifier(value="applicationProperties")
    private Properties m_testProps;

但我得到了这个例外，“无法解析占位符'quickbase.username'”。我需要做什么才能让我的财产在那里？

由于其他一切都很好，因此您的属性文件一定不在类路径上。我假设您正在从单元测试中运行它，尝试使用这个虚拟测试，假设您的上下文 xml 文件名是testContext.xml：

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:testContext.xml")
public class MyTest {

@Autowired
myprojectClient myprojectClient;

@Test
public void test()
{
    //use myProjectClient
}

}

通过这种方式，您可以使用 Spring 上下文开始测试，该上下文从@ContextConfiguration. 可以使用多个上下文文件。还有一件事，使用大写字母作为类名。

尝试将ignoreUnresolvablePlaceholders设置为 true 并重试。

<property name="ignoreUnresolvablePlaceholders" value="true"/>

您的应用程序中可能有多个 org.springframework.beans.factory.config.PropertyPlaceholderConfigurer（可能在您的应用程序上下文和测试上下文中）。
