springboot 集成elasticsearch

springboot 集成elasticsearch,对graylog日志做相应的处理

1.pom配置

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.1.3.RELEASE</version>
    <relativePath/>
</parent>
<modelVersion>4.0.0</modelVersion>

<artifactId>log-elasticsearch</artifactId>

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
    <java.version>1.8</java.version>
    <jest.version>6.3.1</jest.version>
    <log4j>2.8.2</log4j>
</properties>


<dependencies>

    <!-- Spring Boot Elasticsearch 依赖 -->
    <dependency>
        <groupId>org.springframework.data</groupId>
        <artifactId>spring-data-elasticsearch</artifactId>
        <version>3.1.9.RELEASE</version>
    </dependency>

    <!--Jest工具包 -->
    <dependency>
        <groupId>io.searchbox</groupId>
        <artifactId>jest</artifactId>
        <version>${jest.version}</version>
    </dependency>


    <!-- Spring Boot Web 依赖 -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>

    <dependency>
        <groupId>org.apache.logging.log4j</groupId>
        <artifactId>log4j-core</artifactId>
        <version>${log4j}</version>
    </dependency>

    <dependency>
        <groupId>org.apache.logging.log4j</groupId>
        <artifactId>log4j-api</artifactId>
        <version>${log4j}</version>
    </dependency>


    <!-- Junit -->
    <dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>4.12</version>
    </dependency>

    <dependency>
        <groupId>org.projectlombok</groupId>
        <artifactId>lombok</artifactId>
    </dependency>
</dependencies>

2.yml文件配置

server:
    port: 8011

    
spring:
    banner:
    charset: utf-8
    application:
             name: log-elasticsearch
    http:
      encoding:
        charset: utf-8
        enabled: true
        force: true
    messages:
      encoding: UTF-8

    data:
      elasticsearch:
        repositories:
          enabled: true
        cluster-nodes: XXXXXX:9300
        cluster-name: docker-cluster


注：
1）cluster-nodes: XXXXXX:9300，端口是9300，Java与elasticsearch通信是9300 不是9200
2）cluster-name: docker-cluster；集群名称配置，否则报错
failed to load elasticsearch nodes : org.elasticsearch.client.transport.NoNodeAvailableException: None of the configured nodes are available

3.索引实体类配置

注：
1）@Document(indexName = "graylog_0", type = "message")   要配置索引名称与参数类型
2）private Long id;   必须添加id字段
3）字段名与数据库字段名一致

4.调用查询

@Override
public List<Graylog> searchAppName(String appName, Integer pageNumber, Integer pageSize) {
    // 分页参数
    Pageable pageable = PageRequest.of(pageNumber, pageSize);
    QueryStringQueryBuilder builder = new QueryStringQueryBuilder(appName);
    SearchQuery searchQuery = new NativeSearchQueryBuilder().withPageable(pageable).withQuery(builder).build();
    System.out.println("查询的语句:" + searchQuery.getQuery().toString());
    Page<Graylog> searchPageResults = graylogRepository.search(searchQuery);
    return searchPageResults.getContent();
}
