bug收集

不想规范格式，好困想睡觉，没写原因，以后有机会慢慢补充（我猜没机会）
欢迎补充解决方法

1. Request method 'POST' not supported
   解决：错误的适用POST去请求GET一类的方法；
   查看controller，@RequestBody使用post，@RequestParam使用GET

2. java.lang.IllegalStateException: Failed to execute CommandLineRunner
   解决：需要implements ApplicationRunner

3. spring cloud报错com.netflix.client.ClientException: Load balancer does not have available server for client:
   解决：
   看一下注册中心微服务的名称：spring-application-name:
   添加
   eureka-client:
   registerWithEureka: true #是否向服务注册中心注册自己
   fetch-registry: true #添加这句

4. spring-boot 整合redis报错：Caused by: java.lang.NoClassDefFoundError: redis/clients/util/SafeEncoder
   解决：降低版本
   
   redis.clients
   jedis
   2.9.0
   

5. controller 接收参数intger为0时，mybatis sql查询无法判断是否为空
   解决：intger为0就相当于null

6. spring boot redis报错：org.springframework.data.redis.RedisSystemException: Error in execution; nested exception is io.lettuce.core.RedisCommandExecutionException: NOAUTH Authentication required.
   解决：redis需要密码

7. Caused by: javax.net.ssl.SSLHandshakeException: java.security.cert.CertificateException: java.security.cert.CertPathValidatorException: Path does not chain with any of the trust anchors
   解决：jdbl增加属性useSSL=false

8. Spring Boot 报错：Could not transfer artifact (https://repo.maven.apache.org/maven2): Received fatal alert: protocol_version -> [Help 1]
   解决： jdk使用1.8版本
