我正在尝试使用Spring Boot来构建应用程序.我正在尝试配置jersy.

i am trying to build an application using spring boot. i am trying to configure jersy .

public class DemoApplication{ private static class Configuration extends AbstractApplicationConfiguration { } public static void main(String[] args) { ConfigurableApplicationContext ctx = SpringApplication.run(Configuration.class, args); } } @Configuration @Import({ WebXmlConfiguration.class}) @ImportResource({ "classpath*:META-INF/spring/appContext.xml" }) @EnableAutoConfiguration(exclude = { DataSourceAutoConfiguration.class, HibernateJpaAutoConfiguration.class, DataSourceTransactionManagerAutoConfiguration.class, FlywayAutoConfiguration.class, SecurityAutoConfiguration.class }) public class AbstractApplicationConfiguration { } @Configuration public class WebXmlConfiguration { @Bean public Filter springSecurityFilterChain() { return new DelegatingFilterProxy(); } @Bean public ServletRegistrationBean jersey() { System.out.println("initalized jersey"); Servlet jerseyServlet = new SpringServlet(); try{ System.out.println(jerseyServlet.getServletConfig().getServletName()); }catch (Exception e) { e.printStackTrace(); } ServletRegistrationBean jerseyServletRegistration = new ServletRegistrationBean(); jerseyServletRegistration.setServlet(jerseyServlet); jerseyServletRegistration.addUrlMappings("/*"); jerseyServletRegistration.setName("jersey-servlet"); jerseyServletRegistration.setLoadOnStartup(1); jerseyServletRegistration .addInitParameter("com.sun.jersey.api.json.POJOMappingFeature", "true"); jerseyServletRegistration.addInitParameter("com.sun.jersey.spi.container.ContainerResponseFilters", ResponseCorsFilter.class.getName()); jerseyServletRegistration.addInitParameter("com.sun.jersey.config.feature.DisableWADL", "true"); System.out.println("end of spring config"); // debugging for development: // jerseyServletRegistration.addInitParameter("com.sun.jersey.spi.container.ContainerRequestFilters", // LoggingFilter.class.getName()); return jerseyServletRegistration; } }

当我运行此代码时，出现错误消息"ResourceConfig实例不包含任何根资源类".日志与下面共享.并且每当我按下api时，都会出现相同的错误"ResourceConfig实例不包含任何根资源类."

when i run this code i get an error saying " The ResourceConfig instance does not contain any root resource classes". the log is shared with below. and whenever i hit an api the same error appears " The ResourceConfig instance does not contain any root resource classes."

推荐答案

创建配置类

@Configuration public class JerseyConfig extends ResourceConfig { public JerseyConfig() { register(JerseyController.class); } }

这个JerseyController类将具有所有其余的末端

This JerseyController Class is the one that will have all the rest ends

@Component @Path("/jersey") public class JerseyController { @GET @Produces("application/json") public String health() { System.out.println("Here"); return "Jersey: Up and Running!"; } }

希望这会有所帮助(注意:请不要忘记为Spring boot添加jersey依赖项)

Hope this helps (note : donot forget to add the jersey dependency for Spring boot)
