elasticsearch，spring boot，mybatis项目小结

最近接手一个活，用springboot整合mybatis获取一批数据，上传到elastic search建索引。小小研究了一下，操作不多，没有很难。

很好的教程

例

 

遇到比较典型的错：

No serializer found for class elasticSearch.LogModel and no properties discovered to create BeanSerializer (to avoid exception, disable SerializationFeature.FAIL_ON_EMPTY_BEANS)

大意是模板类没有set方法，故报错。用对象转json的时候报的。

 

错2

Jackson2需要引3个maven包

<!-- https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-databind -->

<dependency>

<groupId>com.fasterxml.jackson.core</groupId>

<artifactId>jackson-databind</artifactId>

<version>2.9.0.pr3</version>

</dependency>

<!-- https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-annotations -->

<dependency>

<groupId>com.fasterxml.jackson.core</groupId>

<artifactId>jackson-annotations</artifactId>

<version>2.9.0.pr3</version>

</dependency>

<!-- https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-core -->

<dependency>

NoNodeAvailableException[None of the configured nodes are available: [{#transport#-1}{127.0.0.1}{localhost/127.0.0.1:9201}]]

这个是因为配置文件中没有配，网上有文章写创建conf，真是乱讲。（后来又报了一次这个错，是因为client连接关闭了还调用连接，spring的@autowire标签初始化类只调用一次构造方法，我创建连接的代码写构造方法里了，

1. $ vi config/elasticsearch.yml
2. #cluster name
3. cluster.name: sojson-application
4. #节点名称
5. node.name: node-1
6. #绑定IP和端口
7. network.host:123.88.88.88
8. http.port:9200
