4. Run
Use mvn spring-boot:run to run the project, test in centos6, windows10, jdk8 environment, the UI is not displayed normally, according to stackoverflow and the official source code issue can not be resolved. When excluding the dependencies of the eureka project, it is found that the freemarker-2.3.x-incubating dependency is based on the query of the maven central warehouse. There should be issues with this incubating version. The freemarker version is adjusted as follows:
<dependency>
<groupId>org.freemarker</groupId>
<artifactId>freemarker</artifactId>
<version>2.3.23</version>
</dependency>
After recompiling and starting the project, the problem is solved.
Notes:
- To customize the dashboard display interface, you can copy the static and templates folders in spring-cloud-netflix-eureka-server-1.xxRELEASE.jar to the src/main/resources directory in the current maven project for custom modification.
- The service center runs for a period of time and prompts
EMERGENCY! EUREKA MAY BE INCORRECTLY CLAIMING INSTANCES ARE UP WHEN THEY'RE NOT. RENEWALS ARE LESSER THAN THRESHOLD AND HENCE THE INSTANCES ARE NOT BEING EXPIRED JUST TO BE SAFE.
According to the investigation, it is related to the self-registration service. - The information environment under system status displays test
Environment test Data center default
