问题:

I am trying to deploy my eureka-service at wildfly, but when i try to access the dashboard i get the following xml as response:

Does anyone know how to get dashboard deploying at wildfly?

回答1:

In my case the other two solutions didn't help.

I searched for hours and found the solution while debugging the spring code. The viewResolver for freemarker did not found the templates in spring-cloud-netflix-eureka-server-1.3.1.RELEASE.jar.

In fact i only had to set one simple property to get the things done:

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

回答2:

For me, the issue was that I had an empty folder, src/main/resources/templates. When this folder exists, FreeMarkerView cannot see the embedded templates contained in spring-cloud-netflix-eureka-server. I don't remember where this folder originated but I suspect it is in the online sample. Deleting it corrected the issue.

I had the same issue using the following pom.xml:

<?xml version="1.0" encoding="UTF-8"?>

            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
    </plugins>
</build>

This was the pom.xml of the auto generated https://start.spring.io/ page. It turns out, that I had to change the version number of the spring-boot-starter-parent artifact to a lower version, in order to display the eureka dashboard correctly.

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

I have encounted this problem recently. At last, I found it was caused by the bad freemarker jar, I removed the freemarker jar from my local maven repos and re-downloaded it again, then it was solved.
