配置了euruka、hystrix、feign、zuul，两个相同的提供者，一个消费者
eureka配置文件如下：
server:
port: 6061
spring:
application:

eureka:
server:
enable-self-preservation: false #禁用保护,默认true
eviction-interval-timer-in-ms: 10000 #清理间隔（默认是60*1000）
client:
fetch-registry: false #是否向eureka server获取列表信息
register-with-eureka: false #是否向自己注册
service-url:
defaultZone: http://admin:123@localhost:6061/eureka/
zuul配置文件如下：
server:
port: 7070
spring:
application:
name: gateway-zuul
eureka:
client:
service-url:
defaultZone: http://admin:123@localhost:6061/eureka/
zuul:

# timeout: 10s # 数据库连接超时时间，2.0 中该参数的类型为Duration，这里在配置的时候需要指明单位
# # 连接池配置，2.0中直接使用jedis或者lettuce配置连接池
# jedis:
# pool:
# max-idle: 50 # 最大空闲连接数
# min-idle: 10 # 最小空闲连接数

errorThresholdPercentage: 50 #错误率，默认50%
forceOpen: false #强制打开断路器，默认false(true打开后会强制断开服务)
测试了返回Integer的login方法与addComment方法，没有问题，返回List的showBlogs方法一直降级处理，第一次报504超时，后面返回空
<select id="login" resultType="Integer">
select count(1) from user where `userName`=#{arg0} and `password`=#{arg1}
</select>
<select id="showBlogs" resultType="com.aisling.pojo.BlogDetail">
SELECT * FROM blog_detail ORDER BY createDate desc
</select>
<insert id="addComment" parameterType="com.aisling.pojo.BlogComment">
INSERT INTO blog_comment(blogId,content,createUser,createDate)
VALUES(#{blogId},#{content},#{createUser},#{createDate});
</insert>
provider端没有问题
