我可以ping遠程服務器ip，因此沒有連接問題。 我可以在tomcat中運行相同的代碼，並且工作正常。 當我將它部署在web球體中時，相同的代碼給了我上述錯誤。 在堆棧溢出嘗試其他的東西沒有工作。 罐子是activation-1.1.jar，mail-1.4.5.jar。 任何指針都有幫助。

Answer 1

那麼，在我們的測試中，我們使用這個搖籃依存關係郵件適配器：

mailVersion = '1.5.5' 

testRuntime "com.sun.mail:javax.mail:$mailVersion" 
testRuntime "com.sun.mail:smtp:$mailVersion" 
testRuntime "com.sun.mail:pop3:$mailVersion" 
testRuntime "com.sun.mail:imap:$mailVersion" 

因此，考慮到加com.sun.mail:imap:1.5.5爲您的項目。

Answer 2

感謝這些回答和評論肯定有幫助。

起初，我用下面的代碼： -

<dependency> 
     <groupId>javax.mail</groupId> 
     <artifactId>javax.mail-api</artifactId> 
     <version>1.5.3</version> 
    </dependency> 
    <dependency> 
     <groupId>com.sun.mail</groupId> 
     <artifactId>javax.mail</artifactId> 
     <version>1.5.3</version> 
    </dependency> 

這解決了IMAP提供的問題。所有的工作在當地，但是當我部署在WebSphere上的代碼我正在類轉換異常

caused by: java.lang.ClassCastException: com.sun.mail.handlers.text_plain incompatible with javax.activation.DataContentHandler 

即使text_plain從DataContenHandler延伸，但保留在抱怨不同的類，它告訴它是越來越加載其他地方。然後排除激活罐如下，以使其工作

<dependency> 
     <groupId>javax.mail</groupId> 
     <artifactId>javax.mail-api</artifactId> 
     <version>1.5.3</version> 
     <exclusions> 
      <exclusion> 
       <artifactId>activation</artifactId> 
       <groupId>javax.activation</groupId> 
      </exclusion> 
     </exclusions> 
    </dependency> 
    <dependency> 
     <groupId>com.sun.mail</groupId> 
     <artifactId>javax.mail</artifactId> 
     <version>1.5.3</version> 
     <exclusions> 
      <exclusion> 
       <artifactId>activation</artifactId> 
       <groupId>javax.activation</groupId> 
      </exclusion> 
     </exclusions> 
    </dependency> 

謝謝你們。
