springCloud 搭建eureka服务之天坑

这里我是采用gradle来管理jar包的。

1、使用idea创建一个gradle项目。

2、编辑settings.gradle文件

1rootProject.name = 'jtm'
2//include 'jtm_core'
3//include 'jtm_sys'
4//include 'jtm_eureka'
5
6def dir = new File(settingsDir.toString())
7def projects = new HashSet()
8def projectSymbol = File.separator + 'src'
9
10dir.eachDirRecurse { subDir ->
11    def subDirName = subDir.canonicalPath
12    def isSubProject = true
13    if (subDirName.endsWith(projectSymbol)) {
14        for (String projectDir in projects) {
15            if (subDirName.startsWith(projectDir)) {
16                isSubProject = false
17                break
18            }
19        }
20        if (isSubProject) {
21            projects << subDirName
22            def lastIndex = subDirName.lastIndexOf(projectSymbol)
23            def gradleModulePath = subDirName.substring(dir.canonicalPath.length(), lastIndex).replace(File.separator, ':')
24            println "include " + gradleModulePath
25            include gradleModulePath
26        }
27    }
28}

3、编辑build.gradle文件

1buildscript {
2    ext {
3        springBootVersion = '2.0.4.RELEASE'
4        springCloudVersion = 'Finchley.SR1'
5    }
6    repositories {
7        maven { url "http://maven.aliyun.com/nexus/content/groups/public/" }
8        mavenCentral()
9    }
10    dependencies {
11        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
12    }
13}
14
15allprojects {
16    apply plugin: 'java'
17    apply plugin: 'idea'
18    apply plugin: 'org.springframework.boot'
19    apply plugin: 'io.spring.dependency-management'
20
21    group 'com.dqcer'
22    version '1.0-SNAPSHOT'
23    sourceCompatibility = 1.8
24
25    repositories {
26        maven { url "http://maven.aliyun.com/nexus/content/groups/public/" }
27        mavenCentral()
28    }
29
30    dependencies {
31        testCompile('org.springframework.boot:spring-boot-starter-test')
32    }
33
34    dependencyManagement {
35        imports {
36            mavenBom "org.springframework.cloud:spring-cloud-dependencies:${springCloudVersion}"
37        }
38    }
39}

4、在当前项目中新建子项目jtm_eureka

5、修改子项目中的build.gradle文件

1dependencies {
2    compile('org.springframework.cloud:spring-cloud-starter-netflix-eureka-server')
3}

6、在子项目中添加配置文件后，运行。

报错：

1com.netflix.discovery.shared.transport.TransportException: Cannot execute request on any known server
2
3Caused by: java.net.ConnectException: Connection refused: connect

网上查阅资料后，更改子项目中的配置文件yml如下：

server:  port: 9001  servlet:    context-path: /eurekaeureka:  instance:    hostname: localhost  client:    fetch-registry: false    register-with-eureka: false    service-url:      defaultZone: http://${eureka.instance.hostname}:${server.port}${server.servlet.context-path}

再次运行，还是这个错，网上说将main方法的注解改了、驼峰名称，或者jar缺失等。都试过。并没有什么作用。冷静查看输入日志发现端口号是8080

多次尝试后得出结论，配置文件名必须为application.yml,不然程序找不到，就会默认配置后，不管如何发现并没有什么用。
