其球衣版本您使用？ –

請提供'web.xml'和'pom'或依賴列表。 @Meiko它是1. \ * – zyexal

請參閱http://stackoverflow.com/questions/28652337/jersey-rest-nosuchmethoderror-com-sun-jersey-core-reflection-reflectionhelper –

你如果你想要正確輸出最新的版本號是1.19.1，請使用正確的版本。使用這個嘗試單詞

如果你還沒有聲明正確的工件，改變版本並沒有什麼幫助。導入正確的庫。 – zyexal

可能是問題，小服務程序的API dependcy：使用這個在你的Maven POM的爲例：

<!-- servlet api 3 --> 
    <dependency> 
     <groupId>javax.servlet</groupId> 
     <artifactId>javax.servlet-api</artifactId> 
     <version>3.0.1</version> 
    </dependency>
