[spring-cloud供应者消费者模式(上)：配置供应者][spring-cloud 2]

--------------------

一：轮询机制(默认)

将供应者项目复制一份，然后修改其中一个的端口(在application.yml文件中port处修改)，用两个供应者测试，后将两个项目启动，消费者项目启动，用消费者端口访问刷新页面，两个供应者轮着进行：

二：随机机制

在消费者的application.yml文件里加上代码：

#供应者application名称
    tencent-user-provider:
      #随机策略
      ribbon:
        NFLoadBalancerRuleClassName: com.netflix.loadbalancer.RandomRule

为了方便测试，在两个供应者上写个方法：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MTU5NTcwMA_size_16_color_FFFFFF_t_70 1][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MTU5NTcwMA_size_16_color_FFFFFF_t_70 2][]

在消费者上写个方法(和供应者方法一样)：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MTU5NTcwMA_size_16_color_FFFFFF_t_70 3][]

在消费者实现方法：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MTU5NTcwMA_size_16_color_FFFFFF_t_70 4][]

在Controller中编写代码：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MTU5NTcwMA_size_16_color_FFFFFF_t_70 5][]

然后将服务中心，两个供应者，消费者启动，用消费者访问，然后查看控制台输出结果，可以看出并不是轮流执行：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MTU5NTcwMA_size_16_color_FFFFFF_t_70 6][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MTU5NTcwMA_size_16_color_FFFFFF_t_70 7][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MTU5NTcwMA_size_16_color_FFFFFF_t_70 8][]
