我正在使用this tutorial,它适用于简单的Java Web应用程序。现在我想将其转换为Spring Boot。我删除了web.xml并将以下两个注释添加到DemoServlet
@RestController
public class DemoServlet extends DispatcherServlet {
private static final long serialVersionUID = 1L;
private static final Logger LOG = LoggerFactory.getLogger(DemoServlet.class);
@RequestMapping("/DemoService.svc/*")
protected void service(final HttpServletRequest req, final HttpServletResponse resp) throws ServletException, IOException {
try {
// create odata handler and configure it with CsdlEdmProvider and Processor
OData odata = OData.newInstance();
ServiceMetadata edm = odata.createServiceMetadata(new DemoEdmProvider(), new ArrayList<EdmxReference>());
ODataHttpHandler handler = odata.createHandler(edm);
handler.register(new DemoEntityCollectionProcessor());
// let the handler do the work
handler.process(req, resp);
} catch (RuntimeException e) {
LOG.error("Server Error occurred in ExampleServlet", e);
throw new ServletException(e);
}
}
}
我还将HTTPServlet更改为DispatcherServlet。
现在,我只能访问一个端点。即
http://localhost:8080/DemoService.svc/
元数据端点不起作用。它返回服务文档而不是xml内容。
http://localhost:8080/DemoService.svc/$metadata
有人可以解释这里发生了什么吗?

为用户使用以下代码作为处理方法。
handler.process(new HttpServletRequestWrapper(request) {
// Spring MVC matches the whole path as the servlet path
// Olingo wants just the prefix, ie upto /odata, so that it
// can parse the rest of it as an OData path. So we need to override
// getServletPath()
@Override
public String getServletPath() {
return "/DemoService.svc";
}
}, response);

在handler.register调用之后添加以下内容:
req.setAttribute(“ requestMapping”,“ /DemoService.svc”);

您可以创建一个@Configuration
并在其中映射servlet,如下所示:
@Bean
public ServletRegistrationBean odataServlet() {
ServletRegistrationBean odataServRegstration = new ServletRegistrationBean(new CXFNonSpringJaxrsServlet(),
"/DemoService.svc/*");
Map<String, String> initParameters = new HashMap<>();
initParameters.put("javax.ws.rs.Application", "org.apache.olingo.odata2.core.rest.app.ODataApplication");
initParameters.put("org.apache.olingo.odata2.service.factory",
"com.metalop.code.samples.olingo.springbootolingo2sampleproject.utils.JPAServiceFactory");
odataServRegstration.setInitParameters(initParameters);
return odataServRegstration;
}

here是olingo2和spring-boot的最佳实现。我建议您看一下这个存储库,它非常简单直接。
