Swagger 2与Spring启动应用程序集成

标签： spring-mvc spring-boot swagger swagger-ui swagger-2.0

将Swagger2与Spring启动应用程序集成时出错。我坚持这个实现。实现或配置有什么问题吗？

以下是我整合Swagger2所做的配置。

SwaggerConfig.java 

<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger2</artifactId>
    <version>2.5.0</version>
</dependency>
<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger-ui</artifactId>
    <version>2.5.0</version>
</dependency>

的pom.xml

添加了swagger2

答案 0 :(得分：2)

我终于找到了解决这个问题的方法。 Swagger UI将自己的UI相关模块添加到您的jar文件中。如果您想查看Swagger UI，应用程序中不应该有任何其他@EnableWebMvc。我在ExceptionHandler之一上有这个注释，因为在尝试访问Swagger UI时我收到了错误。
