從swagger編輯器生成JAX-RS服務器不起作用

Question

我試圖用swagger編輯器（http://editor.swagger.io/#/）從文檔生成JAX-RS服務器。

我選擇生成服務器 - > JAX-RS，並試圖在Apache TomEE 1.7.4運行代碼，並得到了以下錯誤：

Answer 1

問題是 「JAX-RS」 上招搖編輯器沒有按不是指「JAX-RS」，而是「球衣」。在TomEE中提供了JAX-RS，因此您可以從pom中刪除幾乎所有的依賴關係。

Swagger也具有JAX-RS服務器的「CXF」風格，這將適合更好的TomEE默認堆棧。

Answer 2

您確定要正確構建WAR包嗎？

要在TomEE運行，必須通過改變包裝如下更新pom.xml中：

<packaging>war</packaging> 

那麼對於使用Maven運行，您可以添加tomee - Maven的插件（pom.xml中） ：

<plugins> 
... 
<plugin> 
    <groupId>org.apache.openejb.maven</groupId> 
    <artifactId>tomee-maven-plugin</artifactId> 
    <version>1.7.4</version> 
    <configuration> 
    <tomeeVersion>1.7.4</tomeeVersion> 
    <tomeeClassifier>plus</tomeeClassifier> 
    </configuration> 
</plugin> 
... 
</plugins> 

最後：

mvn clean package 
mvn tomee:run 

而且瞧

http://localhost:8080/swagger-jaxrs-server-1.0.0/ works!
