我正在尝试使用spring boot构建应用程序。我正在尝试配置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，我收到一条错误消息“ResourceConfig实例不包含任何根资源类”。日志与下面共享。每当我点击api时出现相同的错误“ResourceConfig实例不包含任何根资源类。”

答案 0 :(得分：1)
创建配置类
@Configuration
public class JerseyConfig extends ResourceConfig {
public JerseyConfig() {
register(JerseyController.class);
}
}
这个JerseyController类是剩下的所有结尾
@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：不要忘记为Spring启动添加球衣依赖性）
