springcloud(Greenwich.SR2版本)搭建遇到的问题

eureka注册中心

application.yml文件如下

server:
  port: 8761
eureka:
  instance:
    hostname: localhost
  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

注意事项

eureka依赖变更

原来的依赖

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-eureka</artifactId>
</dependency>

现在的依赖

<dependency>
  <groupId>org.springframework.cloud</groupId>
  <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
</dependency>

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>
```
