与spring-boot和jersey集成时如何查找togglz网址 [英] How to find the togglz url when integrating with spring-boot and jersey

问题描述

我的应用程序基于spring-boot和jersey.我已经在我的应用程序中配置了Togglz.我可以成功启动Web应用程序，但运行gradle bootRun.从启动期间的输出中，我可以看到以下日志消息.但是我无法访问 http://localhost:8080/togglz .我的应用程序根目录路径是"/"，由jersey管理.看来spring-mvc在togglz上可以很好地工作，但是在与jersey集成时无法访问它.我该怎么做才能让球衣接受网址?

My application based on spring-boot and jersey. I have configured togglz in my application. I can successfully launch my web application but running gradle bootRun. From the output during the startup, I am able to see below log message. But I am not able to access http://localhost:8080/togglz. My application root path is "/" which is managed by jersey. It seems that spring-mvc works well with togglz but failed to access it when integrating with jersey. What should I do in order to let jersey to accept the url?

推荐答案

为使Jersey 2与Spring Boot应用程序中的Spring MVC端点一起使用，我建议确保您的application.yml (或.properties进行此类区分，例如:

For Jersey 2 to work along with Spring MVC endpoints in a Spring Boot application, I would suggest to make sure your application.yml (or .properties makes such distinction, something like:

...
# Spring MVC dispatcher servlet path. Needs to be different than Jersey's to enable/disable Actuator endpoints access (/info, /health, ...)
server.servlet-path: /
# Jersey dispatcher servlet
spring.jersey.application-path: /api
...

如果您要在Spring Boot应用程序中将Jersey 1与Spring MVC端点集成，Spring Boot不会提供jersey 1启动程序，因此所有内容都需要手动"配置，但基本上是Jersey servlet映射到"/"，您需要对其进行配置，以将404传递给servlet容器以进行进一步处理(可能是Spring MVC或普通servlet端点).像这样:

If you are integrating Jersey 1 with Spring MVC endpoints in a Spring Boot app, Spring Boot doesn't provide a jersey 1 starter so everything needs to be "manually" configured, but basically if your Jersey servlet is mapped to "/", you would need to configure it to let pass 404 to the servlet container for further handling (maybe a Spring MVC or plain servlet endpoint). Something like:

Jersey 1资源配置:

Jersey 1 resources configuration:

@ApplicationPath("/")
public class DemoResourcesConfig extends PackagesResourceConfig {

  private static final Map<String, Object> properties() {
    Map<String, Object> result = new HashMap<>();
    result.put(PackagesResourceConfig.PROPERTY_PACKAGES, "com.sun.jersey;com.asimio.api.demo1.rest");
    // To forward non-Jersey paths to servlet container for Spring Boot actuator endpoints to work.
    result.put("com.sun.jersey.config.feature.FilterForwardOn404", "true");
    result.put(JSONConfiguration.FEATURE_POJO_MAPPING, "true");
    return result;
  }

  public DemoResourcesConfig() {
    super(properties());
  }
...
}

泽西岛1资源实施:

package com.asimio.api.demo1.rest;
...
@Component
@Path("/actors")
@Produces(MediaType.APPLICATION_JSON)
public class ActorResource {

  @GET
  public List<Actor> findActors() {
...
  }

  @GET
  @Path("{id}")
  public Actor getActor(@PathParam("id") String id) {
...
  }
...
}

ServletContextInitializer bean

@Bean
  public ServletContextInitializer servletInitializer() {
    return new ServletContextInitializer() {

      @Override
      public void onStartup(ServletContext servletContext) throws ServletException {
        final ServletRegistration.Dynamic appServlet = servletContext.addServlet("jersey-servlet", new SpringServlet());
        Map<String, String> filterParameters = new HashMap<>();
        // Set filter parameters
        filterParameters.put("javax.ws.rs.Application", "com.asimio.api.demo1.config.DemoResourcesConfig");
        appServlet.setInitParameters(filterParameters);
        appServlet.setLoadOnStartup(2);
        appServlet.addMapping("/*");
      }
    };
  }

application.yml

application.yml

...
# For Spring MVC to enable Endpoints access (/admin/info, /admin/health, ...) along with Jersey
server.servlet-path: /admin
...
