项目名称：KOCA
KOCA版本 ：5.2.0
KOCA模块 ：网关
模块版本 ：5.2.0
场景 ：eureka开启了认证，网关想对认证的密码进行密文配置
问题 ：无法连接注册中心
报错细节 ：
网关配置：
eureka:
instance:
prefer-ip-address: true
status-page-url-path: ${management.endpoints.web.base-path}/info
health-check-url-path: ${management.endpoints.web.base-path}/health
instance-id: ${spring.cloud.client.ip-address}:${server.port}
metadata-map:
management.context-path: ${management.endpoints.web.base-path}
client:
service-url:
defaultZone: http://user:ENC(zYyoF7424UE=)@localhost:8085/eureka/
启动报错：

尝试解决方案：
第一步：把密码改成明文测试：发现能成功连接注册中心
eureka:
instance:
prefer-ip-address: true
status-page-url-path: ${management.endpoints.web.base-path}/info
health-check-url-path: ${management.endpoints.web.base-path}/health
instance-id: ${spring.cloud.client.ip-address}:${server.port}
metadata-map:
management.context-path: ${management.endpoints.web.base-path}
client:
service-url:
defaultZone: http://user:123456@localhost:8085/eureka/
说明网关启动时
http://user:ENC(zYyoF7424UE=)@localhost:8085/eureka/
解密不成功。
第二步：加密依赖检查，发现网关没有引入下面的依赖
<dependency>
<groupId>com.szkingdom.koca.base</groupId>
<artifactId>koca-crypto</artifactId>
</dependency>
第三步：断点调试：
必须要以
ENC(开始，)结束才有才能正常解析。
第四步：采用如下方式，问题解决
test:
des: ENC(zYyoF7424UE=)
eureka:
instance:
prefer-ip-address: true
status-page-url-path: ${management.endpoints.web.base-path}/info
health-check-url-path: ${management.endpoints.web.base-path}/health
instance-id: ${spring.cloud.client.ip-address}:${server.port}
metadata-map:
management.context-path: ${management.endpoints.web.base-path}
client:
service-url:
defaultZone: http://user:${test.des}@localhost:8085/eureka/
第五步：如果是在网关启动依然启动报错
com.netflix.discovery.shared.transport.TransportException: Cannot execute request on any known server
at com.netflix.discovery.shared.transport.decorator.RetryableEurekaHttpClient.execute(RetryableEurekaHttpClient.java:112)

at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624)
at java.lang.Thread.run(Thread.java:748)
说明解密还是失败，需要添加依赖
<dependency>
<groupId>com.szkingdom.koca.boot</groupId>
<artifactId>koca-boot-autoconfigure</artifactId>
</dependency>
加解密的装配类在这个包下面
第六步：成功解决
