Spring Boot 中的 JAX-RS 和 MVC [英] JAX-RS and MVC at Spring Boot

问题描述

我有一个用作 MVC 的 Spring Boot 应用程序.我想在我的应用程序中使用 JAX-RS 而不使用 Spring 注释.我将在不同的类中同时使用 JAX-RS 注释组件和 MVC 组件.当我添加 Jersey 资源配置时(不注册任何端点):

I have a Spring Boot application which works as MVC. I would like to use JAX-RS at my application without using Spring annotations. I'll have both JAX-RS annotated components and MVC components at different classes. When I add a Jersey Resource Config (without registering any endpoint):

@Component
public class JerseyConfig extends ResourceConfig {

}

我启动了应用程序，但没有显示登录页面.当我打开登录页面时，它像文档一样被下载.我该如何解决?

I startup the application and login page is not shown. Its been downloaded as like a document when I open login page. How can I solve it?

推荐答案

1) 确保您的应用程序的 Spring Boot 配置文件区分 Spring MVC(例如执行器端点)和 Jersey(资源端点):

1) Make sure your app's Spring Boot configuration file makes a distinction between Spring MVC, for actuator endpoints for instance and Jersey for resources endpoints:

application.yml

...
# 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
...

2)确保您的 Spring Boot 应用程序通过以下方式扫描位于特定包(即 com.asimio.jerseyexample.config)中的组件:

2) Make sure your Spring Boot app scans for components located in specific packages (ie com.asimio.jerseyexample.config) via:

@SpringBootApplication(
    scanBasePackages = {
        "com.asimio.jerseyexample.config", "com.asimio.jerseyexample.rest"
    }
)

3) Jersey 配置类实现:

3) Jersey configuration class implementation:

package com.asimio.jerseyexample.config;
...
@Component
public class JerseyConfig extends ResourceConfig {

    ...        
    public JerseyConfig() {
        // Register endpoints, providers, ...
        this.registerEndpoints();
    }

    private void registerEndpoints() {
        this.register(HelloResource.class);
        // Access through /<Jersey's servlet path>/application.wadl
        this.register(WadlResource.class);
    }
}

4) 使用 JAX-RS (Jersey) 的资源实现:

4) Resource implementation using JAX-RS (Jersey):

package com.asimio.jerseyexample.rest.v1;
...
@Component
@Path("/")
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public class HelloResource {

    private static final Logger LOGGER = LoggerFactory.getLogger(HelloResource.class);

    @GET
    @Path("v1/hello/{name}")
    public Response getHelloVersionInUrl(@ApiParam @PathParam("name") String name) {
        LOGGER.info("getHelloVersionInUrl() v1");
        return this.getHello(name, "Version 1 - passed in URL");
    }
...
}

可以在我几个月前创建的博客中找到更详细的操作方法，使用 Spring Boot、Jersey Swagger 和 Docker 的微服务
