遇到的问题:
1. spring 中 日志 中的 logback 必须 保持一致 ,这里我使用 org.slf4j 1.6.4
<groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>1.6.4</version> <type>jar</type> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>1.6.4</version> <type>jar</type> </dependency>
2. hosts 问题,之前一直 有连接 连不同, zookeeper 使用 172.23.27.120:2181,172.23.27.115:2181,172.23.27.116:2181 。是可以连通,但这不是我需要的 ,我需要的是172.23.27.120:2181,172.23.27.115:2181,172.23.27.116:2181/kafka ,,
然后 配置成172.23.27.120:2181,172.23.27.115:2181,172.23.27.116:2181/kafka 就报错,怎么也 不成功,之后 配置172.23.27.120:2181,172.23.27.115:2181,172.23.27.116:2181/kafka的时候发现是 域名了,然后联不通,在本地添加 hosts 就可以解决该问题了。
3.使用 jar 包
<dependency> <groupId>org.springframework.integration</groupId> <artifactId>spring-integration-kafka</artifactId> <version>1.3.0.RELEASE</version> </dependency>
