通常的Eureka仪表盘类似：

但是我的显示为：

问题是，当以可执行文件运行时，相同的战争运行完全正常（spring-boot-maven-plugin既创建了可部署的战争，又可执行文件的战争），但是在 jBoss 6.4 EPA ，它将仪表板显示为xml（我将在下面详细介绍jBoss的属性文件中的差异）

这是 pom ：

这是Application类：

这是作为jar部署时使用的 application.properties ：

package com.tcs.naming.UtxNamingServer;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.support.SpringBootServletInitializer;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;

@SpringBootApplication
@EnableEurekaServer
public class NamingServerApplication extends SpringBootServletInitializer{

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

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(NamingServerApplication.class);
    }
}

现在，需要进行一些更改才能在jBoss中部署战争（没有tomcat依赖项）。这是在jBoss中进行部署时的 application.properties 文件：

spring.application.name=naming-server
server.contextPath=/naming-server

eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false

这是 jboss-web.xml 文件：

spring.application.name=naming-server
server.servlet-path=/*

eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false

这是 jboss-deployment-structure.xml ：

<?xml version="1.0" encoding="UTF-8"?>
<jboss-web>
        <context-root>/naming-server</context-root>
</jboss-web>

jax-rs 子系统被排除在外，因为否则我的Eureka中包含的Jersey实现与jBoss的RESTEasy实现之间存在jar冲突。上面的模块就位于其中，以使 application.properties 文件可用于该应用程序（并且我确认它已经被拾取）

1 个答案:

答案 0 :(得分：0)

默认情况下，Eureka在类路径的.ftl文件夹中搜索 freemarker（templates）模板（用于创建仪表板页面）。由于在一个应用程序服务器上，可能有多个具有该文件夹的jar（并且它们不包含Eureka正在搜索的模板），所以会引发错误。

如here所述，解决方案是将以下属性添加到application.properties，以使Eureka不会在其他jar中搜索templates文件夹

spring.freemarker.prefer-file-system-access=false
