client:
#表示是否将自己注册到Eureka Server，默认为true。
register-with-eureka: false
#表示是否从Eureka Server获取注册信息，默认为true。
fetch-registry: false
service-url:
#设置与Eureka Server交互的地址，查询服务和注册服务都需要依赖这个地址。默认是http://localhost:8761/eureka ；多个地址可使用 , 分隔。
defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/
spring:
application:
name: eureka
注意事项
-
eureka依赖变更增加了netflix公司的名称原来的依赖：
<dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-eureka-server</artifactId> </dependency>现在的依赖：
<dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId> </dependency> -
我在这里开启了
eureka的安全验证。即如下security依赖<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-security</artifactId> </dependency>如果引入安全验证则需要配置访问
eurekabasic认证.以往配置是在application.xml中增加如下配置：注意这是以往的配置： security: basic: enabled: true spring: profiles: peer1 security: user: name: test password: 123456 roles: USER现在要在配置类
WebSecurityConfigurerAdapter中配置@EnableWebSecurity public class WebSecurityConfig extends WebSecurityConfigurerAdapter { /** * @Description: 高版本的丢弃了 * security: * basic: * enabled: true 配置，应该使用以下方式开启 * @Param: [http] * @Return: void */ @Override protected void configure(HttpSecurity http) throws Exception { // Configure HttpSecurity as needed (e.g. enable http basic). http.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.NEVER); //因为 Spring Security 默认开启了所有 CSRF 攻击防御，这里直接关闭csrf http.csrf().disable();// //注意：为了可以使用 http://${user}:${password}@${host}:${port}/eureka/ 这种方式登录,所以必须是httpBasic, // 如果是form方式,不能使用url格式登录 http.authorizeRequests().anyRequest().authenticated().and().httpBasic(); } /** * 配置认证的用户名、密码 * @param auth * @throws Exception */ @Autowired public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception { auth .inMemoryAuthentication().passwordEncoder(new BCryptPasswordEncoder()) //admin .withUser("admin").password(new BCryptPasswordEncoder().encode("123456")).roles("EUREKA-CLIENT").and() //eureka-security-client .withUser("eureka-security-client").password(new BCryptPasswordEncoder().encode("eureka-security-client")).roles("EUREKA-CLIENT") ; } }注意这里的用户名和密码。在访问
eureka是需要填写该用户名和密码。所有服务注册到该eureka是也需要用到这个用户名和密码

注册到
eureka的配置原来的配置
server: port: 8888 eureka: client: service-url: #默认是http://localhost:8761/eureka ；多个地址可使用 , 分隔。 defaultZone: http://localhost:8761/eureka现在的配置
server: port: 8888 eureka: client: service-url: #默认是http://localhost:8761/eureka ；多个地址可使用 , 分隔。 defaultZone: http://${edu.eureka.user}:${edu.eureka.password}@${edu.eureka.host}:${edu.eureka.port}/eureka/注意这里的
defaultZone因为eureka使用了安全认证，所以我们需要在defaultZone地址中增加${edu.eureka.user}:${edu.eureka.password}来登录eureka,这里的用户名和密码就是刚才我们配置eureka的用户名和密码。我们需要在项目的启动参数中配置这些参数：--edu.eureka.user=admin --edu.eureka.password=123456 --edu.eureka.host=localhost --edu.eureka.port=8761 -
实例id改动
原配置：instance: prefer-ip-address: true instance-id: ${spring.cloud.client.ipAddress}:${spring.application.name}:${server.port}现在的配置
instance: prefer-ip-address: true instance-id: ${spring.cloud.client.ip-address}:${spring.application.name}:${server.port}
`ipAddress`改为了`ip-address`

注意事项
-
hystrix依赖变更原来依赖
<dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-hystrix</artifactId> </dependency>现在的依赖
<dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-hystrix</artifactId> </dependency>
-
ribbon依赖变更原来依赖
<dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-ribbon</artifactId> </dependency>现在依赖
<dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-ribbon</artifactId> </dependency> -
eureka依赖变更，这个刚才说过了原来依赖
<dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-eureka</artifactId> </dependency>现在依赖
<dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId> </dependency> -
feign依赖变更原来依赖
<dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-feign</artifactId> </dependency>现在依赖
<dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-openfeign</artifactId> </dependency> -
另外我发现
Greewich.SR2版本如果不添加redis的依赖，会报如下异常:java.lang.ClassNotFoundException org.apache.commons.pool2.impl.GenericObjectPoolConfig,java.lang.ClassNotFoundException: redis.clients.jedis.JedisPoolConfig,即使我的项目没有使用到redis也会报这个异常。所以要引入spring-boot-starter-data-redis并且还要单独引入redis.clients依赖<dependency> <groupId>redis.clients</groupId> <artifactId>jedis</artifactId> </dependency>
