Spring 带弹簧靴的奥林戈

我正在使用它，它适用于一个简单的JavaWeb应用程序。现在我想把它转换成弹簧靴。我删除了web.xml并向DemoServlet添加了以下两个注释

@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);
        }
    }
}

元数据终结点不起作用。它返回服务文档而不是xml内容

http://localhost:8080/DemoService.svc/$metadata

有人能解释一下这里发生了什么吗？

请使用下面的流程方法代码

    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：

setAttribute（“requestMapping”，“/DemoService.svc”）

可以找到olingo2和spring boot的最佳实现。我建议您看看这个存储库，它非常简单明了

您可以创建

@配置

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;

}

@Bean
public ServletRegistrationBean odataServlet（）{
ServletRegistrationBean ODataServRegistration=新的ServletRegistrationBean（新的CXFNonSpringJaxrsServlet（），
“/DemoService.svc/*”；
Map 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”）；
setInitParameters（initParameters）；
回归方程；
}

@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;

}
