我有一个使用Spring Boot 2.0.x.RELEASE的非常简单的演示应用程序

在我的POM中,我有:

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.0.4.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
    <java.version>1.8</java.version>
    <spring-cloud.version>Finchley.RELEASE</spring-cloud.version>
</properties>

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-jersey</artifactId>
        <exclusions>
            <exclusion>
                <!-- We're using undertow as our embedded web container instead of tomcat -->
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-tomcat</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

    <!-- Embedded web container- serves Jersey resources -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-undertow</artifactId>
    </dependency>

    <!-- Support for Spring Actuator & Health Check Endpoints -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-actuator</artifactId>
    </dependency>

    <dependency>
        <groupId>org.springframework.hateoas</groupId>
        <artifactId>spring-hateoas</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-sleuth</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>

</dependencies>

我的主应用程序看起来像:

@SpringBootApplication
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }

    @Bean
    ResourceConfig getJerseyConfig() {
        final HashMap<String, Object> jerseyProperties = new HashMap<>();
        jerseyProperties.put(ServerProperties.MEDIA_TYPE_MAPPINGS, "json : application/json");
        ResourceConfig resourceConfig = new ResourceConfig()
                .register(TestEndpoints.class);
        resourceConfig = resourceConfig.setProperties(jerseyProperties);

        return resourceConfig;
    }
}

然后我尝试击中执行器端点(例如/actuator)时会收到404,但是我可以毫无问题地击中TestEndpoints.java中的端点。我曾在Spring Boot 1.5.x上进行过此操作,但现在看来Jersey不允许执行器端点通过。如果完全删除ResourceConfig bean,则可以执行器端点。我必须添加一些配置以允许执行器端点通过运动衫吗?

1 个答案:

答案 0 :(得分:2)

这是因为默认情况下,Jersey将使用URL映射/*,该映射将占用所有请求,包括对执行器端点的请求,而找不到。有两种解决方案;您可以将Jersey的基本网址更改为其他名称,例如/api/*,也可以将Jersey设置为过滤器(而不是默认的servlet),并设置一个属性以使Jersey将不知道的所有请求转发到servlet容器。这两个示例都可以在this post中找到。
