java - 无法使用 Google App Engine (GAE) 运行 Spring Data Rest

Question

这是我在使用 appengine:devserver 运行 Spring Data Rest 应用程序时看到的错误

虽然存在依赖:

    <dependency>
        <groupId>org.springframework.data</groupId>
        <artifactId>spring-data-rest-webmvc</artifactId>
        <version>2.1.0.RELEASE</version>
    </dependency>

Answer 1

您正在使用的 Spring REST 版本不再有 RepositoryRestExporterServlet，它已被 RepositoryRestDispatcherServlet 取代

spring-data-rest-webmvc 2.0.0 - RepositoryRestExporterServlet missing

这里是从github上改过来的 https://github.com/spring-projects/spring-data-rest/commit/6e4e7da142fde7036bf3d9daa8caa25f8a40b330#diff-ea97fe02024ec0947925b1cf92a34473
