从属性文件读取密码时，Java Mail 身份验证失败

Question

当我从属性文件中读取密码时，我遇到了身份验证失败，但是当我将密码直接放在 applicationContext.xml 中时，它工作正常。

<bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
    <property name="host" value="${host}" />
    <property name="port" value="${port}" />
    <property name="username" value="${username}" />
    <!-- <property name="password" value="${pwd}" /> -->
    <property name="password" value="p@$$w0rd@745" />

    <!-- The name of the property, following JavaBean naming conventions -->

    <property name="javaMailProperties">
        <props>
            <prop key="mail.transport.protocol">smtp</prop>
            <prop key="mail.smtp.auth">true</prop>
            <prop key="mail.smtp.starttls.enable">true</prop>
            <prop key="mail.debug">true</prop>
        </props>
    </property>
</bean>

错误的堆栈跟踪。

设置断点

org.springframework.mail.javamail.JavaMailSenderImpl.setPassword(String)

和

org.springframework.mail.javamail.JavaMailSenderImpl.setUsername(String)

启动您的应用或测试，您会看到有什么到达那里。 这会告诉你哪里出了问题。
