我的 Java 方法无法使用 Java 邮件变量作为参数

Question

我正在 Java 中创建一个程序，用于在用户收到有关密码重置的电子邮件时提醒他们。我已经给自己发送了一封电子邮件，其中包含文本 "Your password has been reset" 并创建了一个分析电子邮件的方法：

    private static boolean passwordResetFinder(String email) {
    boolean passReset = false;

    if (email.matches(".*password.*") && (email.matches(".*changed.*") || email.matches(".*reset.*"))) {
        passReset = true;
    }

我这样调用方法：

String email = new String();
...
open connection to inbox using JavaMail
...

Object content = emailReader.getContent();
email = content.toString();

if(passwordResetFinder(email)) {
   System.out.println("Password Alert");
}

这是行不通的。但是，如果我输入以下内容：

if (passwordResetFinder("Your password has been reset")

或

email = content.toString();    
email = "Your password has been reset";    
    if(passwordResetFinder(email))

有效。这是为什么？

也许 emailReader.getContent() 返回的对象的 toString() 没有为您提供邮件包含的文本的字符串表示形式。如果在读取时它是 Multipart 的子类，则可能是这种情况多部分邮件或 Stream（如果消息的类型未知）。

Return the content as a Java object. The type of the returned object is of course dependent on the content itself. For example, the object returned for "text/plain" content is usually a String object. The object returned for a "multipart" content is always a Multipart subclass. For content-types that are unknown to the DataHandler system, an input stream is returned as the content
