Eureka服务器-Camden.SR2-Spring Boot Starter 1.4.2.0版本

我在尝试使用Eureka服务器运行Spring Boot Starter 1.4.2.RELEASE时遇到以下错误：

Description:

Parameter 0 of method traceFilterRegistration in org.springframework.cloud.netflix.eureka.server.EurekaServerConfiguration required a bean of type 'javax.servlet.Filter' that could not be found.
    - Bean method 'resourceUrlEncodingFilter' in 'FreeMarkerAutoConfiguration.FreeMarkerWebConfiguration' not loaded because @ConditionalOnEnabledResourceChain did not find class org.webjars.WebJarAssetLocator


Action:

Consider revisiting the conditions above or defining a bean of type 'javax.servlet.Filter' in your configuration.

pom.xml：

启动应用程序类：

注意：如果我将spring boot starter父级设置为1.4.1.0版本，那么一切都可以正常工作

这是我的环境：

MacOS Sierra 10.12.1 Spring工具套件-版本：3.8.2.RELEASE构建Id:201610040743-平台：EclipseNeon.1 4.6.1

---

在GitHub上打开了一个问题：

---

通过清理maven repo:rm-r$HOME/.m2解决了这个问题，您可以创建这个bean：

@Bean
public Filter webRequestLoggingFilter() {
    return new CommonsRequestLoggingFilter();
}

---

我能够通过调整SpringBoot和SpringCloud的版本来解决这个问题，特别是SpringBootStarter父版本和SpringCloud依赖关系

为了查看这些文件的最新兼容版本，我创建了一个eureka服务器项目，然后查看了生成的pom.xml

要从上面的链接创建eureka项目，请执行以下操作：

选择我使用的最新spring引导版本 在依赖项中键入“eureka”，然后选择eureka服务器

---

单击“浏览”按钮查看生成的pom.xml。

spring boot和spring cloud之间应该存在不匹配的版本。如果使用SpringBootVersion2.2.0.RELEASE，则必须使用SpringCloud版本Hoxton.RC1。如果使用SpringBootVersion2.1.9.RELEASE，则必须使用SpringCloudVersionGreenwich.SR3

以下是示例：

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.1.9.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

<properties>
    <java.version>1.8</java.version>
    <spring-cloud.version>Greenwich.SR3</spring-cloud.version>
</properties>

我换衣服 格林威治释放 到 Hoxton.SR8

---

通过匹配Spring Boot和Spring Cloud的版本，您可以解决Spring Boot+Spring Cloud带来的许多问题。有关版本矩阵，请参阅此链接。

---

这可能是有害的，许多人在.m2目录中有复杂的settings.xml文件，比如我和其他通过vpn下载的自定义依赖项。完美的解决方案是移除特定的罐子。但是哪一个呢？

@SpringBootApplication
@EnableEurekaServer
public class EurekaServerApplication {
    public static void main(String[] args) {
        SpringApplication.run(EurekaServerApplication.class, args);
    }
}

@Bean
public Filter webRequestLoggingFilter() {
    return new CommonsRequestLoggingFilter();
}

<parent>
    <groupId>org.springframework.boot</groupId>
