启动注意2点,1是内存,2是线程数(此处进行简单安装,后面会详细补充es文档)

在宿主机执行:
sysctl -w vm.max_map_count=262144
vm.max_map_count
参数,是允许一个进程在VMAs拥有最大数量(VMA:虚拟内存地址, 一个连续的虚拟地址空间),当进程占用内存超过时, 直接OOM。
elasticsearch占用内存较高。官方要求max_map_count需要配置到最小262144。

Springboot整合

配置文件
1 spring 2 data: 3 elasticsearch: 4 cluster-nodes: 192.168.180.113:9300 5 cluster-name: docker-cluster
启动类(采用第二种)
1 /** 2 * SpringBoot默认支持两种技术来和ES交互; 3 * 1、Jest(默认不生效) 4 * 需要导入jest的工具包(io.searchbox.client.JestClient) 5 * 2、SpringData ElasticSearch【ES版本有可能不合适】 6 * 版本适配说明:https://github.com/spring-projects/spring-data-elasticsearch 7 * 如果版本不适配:2.4.6 8 * 1)、升级SpringBoot版本 9 * 2)、安装对应版本的ES 10 * 11 * 1)、Client 节点信息clusterNodes;clusterName 12 * 2)、ElasticsearchTemplate 操作es 13 * 3)、编写一个 ElasticsearchRepository 的子接口来操作ES; 14 * 两种用法:https://github.com/spring-projects/spring-data-elasticsearch 15 * 1)、编写一个 ElasticsearchRepository 16 */ 17 @SpringBootApplication 18 public class Springboot03ElasticApplication { 19 ? 20 public static void main(String[] args) { 21 SpringApplication.run(Springboot03ElasticApplication.class, args); 22 } 23 }
nested exception is java.lang.IllegalStateException: availableProcessors is already set to [4], rejecting [4]
我网上查询了一下,有人是是因为整合了Redis的原因。但是我把Redis相关的配置去掉后,问题还是没有解决,最后有人说是因为netty冲突的问题。 也有人给出了解决方式就是在项目初始化钱设置一下一个属性。在初始化之前加上System.setProperty("es.set.netty.runtime.available.processors", "false");
1 @Configuration 2 public class ElasticSearchConfig { 3 @PostConstruct 4 void init() { 5 System.setProperty("es.set.netty.runtime.available.processors", "false"); 6 } 7 }
Bo类
1 @Document(indexName = "topcheer",type = "book" ) 2 @Slf4j 3 @Data 4 @Builder 5 public class Book implements Serializable { 6 ? 7 private Integer id; 8 private String name; 9 private String author; 10 ? 11 public Book(String name, String author) { 12 this.name = name; 13 this.author = author; 14 } 15 ? 16 public Book(Integer id, String name, String author) { 17 this.id = id; 18 this.name = name; 19 this.author = author; 20 } 21 ? 22 public Book() { 23 } 24 }
Repository类
1 public interface BookRepository extends ElasticsearchRepository<Book,Integer> { 2 ? 3 //参照 4 // https://docs.spring.io/spring-data/elasticsearch/docs/3.0.6.RELEASE/reference/html/ 5 public List<Book> findByNameLike(String name); 6 ? 7 }
测试类:
1 @Autowired 2 BookRepository bookRepository; 3 ? 4 @Test 5 public void test02() { 6 Book book = new Book(); 7 book.setId(1); 8 book.setName("西游记"); 9 book.setAuthor("吴承恩"); 10 bookRepository.index(book); 11 ? 12 ? 13 for (Book book1 : bookRepository.findByNameLike("游")) { 14 System.out.println(book1); 15 }; 16 ? 17 }
结果:
