没有 REST 端点在 Spring Boot 应用程序中工作

【中文标题】没有 REST 端点在 Spring Boot 应用程序中工作【英文标题】：no REST endpoint working in spring boot application 【发布时间】：2018-08-11 20:29:24 【问题描述】：

我正在尝试使用REST 端点启动简单的SpringBootApplication。主应用是这样的

@SpringBootApplication
public class JudgeRuleEngineApplication 

    /**
     * Main application.
     * @param args console args
     */
    public static void main(final String[] args) 
        SpringApplication.run(JudgeRuleEngineApplication.class, args);

REST 路由定义如下所示

@Configuration
public class RuleExecutionRest 

    private PlayerRuleCalculationService service;

    /**
     * Constructor injection.
     * @param service calculation service
     */
    @Autowired
    public RuleExecutionRest(final PlayerRuleCalculationService service) 
        this.service = service;
    

    /**
     * Increases player level if needed.
     * @return player
     */
    @Bean
    public RouterFunction<?> validatePlayer() 
        return route(POST("/judge/rest/player"),
            request -> 
                Mono<Player> player = request.bodyToMono(Player.class);
                return ServerResponse.ok().body(fromPublisher(service.levelUp(player), Player.class));
            );

在build.gradle我指定了依赖项

dependencies 
    compile('org.springframework.boot:spring-boot-starter')
    compile('org.springframework.boot:spring-boot-starter-webflux')
    compile('org.springframework.boot:spring-boot-starter-data-jpa')
    compile("org.springframework.boot:spring-boot-starter-actuator")

application.properties 看起来像这样

spring.datasource.url=jdbc:postgresql://localhost:5432/judge-re-db
spring.datasource.username=postgres
spring.datasource.password=postgres
spring.datasource.driver-class-name=org.postgresql.Driver

spring.jpa.database-platform=org.hibernate.dialect.PostgreSQLDialect
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=create

我用gradlew bootRun 开始申请。但是当我尝试访问任何端点时

但它会写入日志

DefaultErrorWebExceptionHandler : Failed to handle request [GET http://127.0.0.1:8080/bad-request]: Response status 404

这样的请求

https://localhost:8080/judge-re/judge/rest/player

    "id": "1",
    "level": "1",
    "experience": "1000"

当我尝试访问 actuator 时，我得到了

2018-03-04 00:02:21.782 ERROR 6864 --- [ctor-http-nio-3] o.s.w.s.adapter.HttpWebHandlerAdapter    : Unhandled failure: An existing connection was forcibly closed by the

有什么问题？

【问题讨论】：

您如何访问您的端点？命令行、浏览器工具、客户端应用程序？你来回的标题是什么样的？是否存在导致它请求 /bad-request 路径的失败或错误客户端？我使用postman 我确实像问题中那样请求但标题为application/json @Kylé 似乎有些东西肯定坏了。它尝试添加带有RestController 注释和GetMapping 的简单类，但仍然无法处理请求 【参考方案1】：

问题是我在做https 请求而不是http。我意识到当我切换到tomcat 时它又返回了我

Invalid character found in method name. HTTP method names must be tokens

【讨论】：

以上是关于没有 REST 端点在 Spring Boot 应用程序中工作的主要内容，如果未能解决你的问题，请参考以下文章

Spring-Boot REST 服务基本 http 身份验证排除一个端点

列出所有已部署的 REST 端点（spring-boot、jersey）

列出所有已部署的 REST 端点（spring-boot、tomcat）

docker 镜像正在运行，但无法在 Spring Boot 应用程序中访问 REST 端点

如何在 Spring Boot 应用程序中实现长轮询 REST 端点？

为啥 spring-boot-starter-jdbc 会破坏我的 REST 端点？
