在Jhipster - Heroku中设置盆景弹性搜索 [英] Setting up bonsai-elasticsearch in Jhipster - Heroku

问题描述

在部署到heroku我的Jhipster应用后，我想使用JSON弹性云搜索（Bonsai）。 Bonsai提供了以下env变量：

  $ BONSAI_URL 
  

这是如何在application-prod.yml中正确添加的？
我一直在阅读文档并尝试将其设置为集群节点值和主机。但我有点失落。

application-prod.yml

  spring：
 devtools：
重新启动：
启用：false 
 livereload：
启用：false 
数据源：
 url：jdbc：mysql ：// localhost：3306 / App？useUnicode = true& characterEncoding = utf8& useSSL = false 
 name：
 username：root 
 password：
 hikari：
 data -source-properties：
 cachePrepStmts：true 
 prepStmtCacheSize：250 
 prepStmtCacheSqlLimit：2048 
 useServerPrepStmts：true 
 jpa：
 database-platform：org.hibernate .dialect.MySQL5InnoDBDialect 
数据库：MYSQL 
 show_sql：false 
属性：
 hibernate.cache.use_second_level_cache：true 
 hibernate.cache.use_query_cache：false 
 hibernate.generate_statistics：false 
 hibernate.cache.region.factory_class：org.hibernate.cache.eh cache.SingletonEhCacheRegionFactory 
 data：
 elasticsearch：
 network：
 host：$ {BONSAI_URL} 
 cluster-name：VLT 
 cluster-nodes：localhost： 9300 
邮箱：
主机：smtp.sendgrid.net 
端口：587 
用户名：$ {SENDGRID_USERNAME} 
密码：$ {SENDGRID_PASSWORD} 
协议：smtp 
 tls：false 
 auth：true 
 from：[e-mail] 
 
 thymeleaf：
缓存：true 
 
 liquibase：
上下文：prod 
 
服务器：
端口：8080 
压缩：
启用：true 
 mime-types：text / html，text / xml，text / plain，text / css，application / javascript，application / json 
 min-response-size：1024 
  

解决方案

我添加了 spring-boot-starter-data-jest ，build.gradle：

   -  compileorg.springframework.boot：spring-boot-starter-data-elasticsearc h
 + compilecom.github.vanroy：spring-boot-starter-data-jest：2.2.0.RELEASE
  

在应用程序类 App.java 中添加了ElasticsearchAutoConfiguration和ElasticsearchDataAutoConfiguration的排除项：

<$ $ {code> @ComponentScan
+ @ EnableAutoConfiguration（exclude = {
+ ElasticsearchAutoConfiguration.class，ElasticsearchDataAutoConfiguration.class}）
@EnableConfigurationProperties（{JHipsterProperties.class，LiquibaseProperties .class}）
public class App {

然后更改：

  import org.elasticsearch.client.Client; 
 -import org.springframework.boot.autoconfigure.AutoConfigureAfter; 
 import org.springframework.context.annotation.Bean; 
 import org.springframework.context.annotation.Configuration; 
 -import org.springframework.data.elasticsearch.core.ElasticsearchTemplate; 
 import org.springframework.data.elasticsearch.core.EntityMapper; 
 import org.springframework.http.converter.json.Jackson2ObjectMapperBuilder; 
 
 import com.fasterxml.jackson.databind.DeserializationFeature; 
 import com.fasterxml.jackson.databind.ObjectMapper; 
 + import com.github.vanroy.springdata.jest.JestElasticsearchTemplate; 
 + import com.github.vanroy.springdata.jest.mapper.DefaultJestResultsMapper; 
 + import io.searchbox.client.JestClient; 
 
 @Configuration 
 public class ElasticSearchConfiguration {
 
 @Bean 
  -  public ElasticsearchTemplate elasticsearchTemplate（客户端客户端，Jackson2ObjectMapperBuilder jackson2ObjectMapperBuilder）{
  -  return新的ElasticsearchTemplate（客户端，新的CustomEntityMapper（jackson2ObjectMapperBuilder.createXmlMapper（false）.build（）））; 
 + public JestElasticsearchTemplate elasticsearchTemplate（JestClient客户端，Jackson2ObjectMapperBuilder jackson2ObjectMapperBuilder）{
 +返回新的JestElasticsearchTemplate（客户端，新的DefaultJestResultsMapper（
 + new CustomEntityMapper（jackson2ObjectMapperBuilder.createXmlMapper（false）.build（））） ）; 
} 
  

然后我添加了配置参数，文件 application.yml ：



  + data：
 + elasticsearch：
 + properties：
 + path：
 + home：target / elasticsearch 
 + transport：
 + tcp：
 + connect_timeout：120s 
 jest：
 + readTimeout ：10000 
 uri：$ {SEARCHBOX_SSL_URL} 
  




After deploying to heroku my Jhipster app, I want to use cloud elasticsearch (Bonsai) with JHipster. Bonsai provides following env variable:

$BONSAI_URL 

How is this properly added in application-prod.yml? I`ve been reading the docs and trying too set it as cluster-nodes value and as host. But i'm a bit lost. Any tips are more than welcome.

application-prod.yml

spring:
devtools:
    restart:
        enabled: false
    livereload:
        enabled: false
datasource:
    url: jdbc:mysql://localhost:3306/App?useUnicode=true&characterEncoding=utf8&useSSL=false
    name:
    username: root
    password:
    hikari:
        data-source-properties:
            cachePrepStmts: true
            prepStmtCacheSize: 250
            prepStmtCacheSqlLimit: 2048
            useServerPrepStmts: true
jpa:
    database-platform: org.hibernate.dialect.MySQL5InnoDBDialect
    database: MYSQL
    show_sql: false
    properties:
        hibernate.cache.use_second_level_cache: true
        hibernate.cache.use_query_cache: false
        hibernate.generate_statistics: false
        hibernate.cache.region.factory_class: org.hibernate.cache.ehcache.SingletonEhCacheRegionFactory
data:
    elasticsearch:
        network:
            host: ${BONSAI_URL}
        cluster-name:  VLT
        cluster-nodes: localhost:9300
mail:
    host: smtp.sendgrid.net
    port: 587
    username: ${SENDGRID_USERNAME}
    password: ${SENDGRID_PASSWORD}
    protocol: smtp
    tls: false
    auth: true
    from: [e-mail]

thymeleaf:
    cache: true

liquibase:
contexts: prod

server:
port: 8080
compression:
    enabled: true
    mime-types: text/html,text/xml,text/plain,text/css, application/javascript, application/json
    min-response-size: 1024

解决方案

I added spring-boot-starter-data-jest library to build script, build.gradle:

-    compile "org.springframework.boot:spring-boot-starter-data-elasticsearch"
+    compile "com.github.vanroy:spring-boot-starter-data-jest:2.2.0.RELEASE"

Added exclude for ElasticsearchAutoConfiguration and ElasticsearchDataAutoConfiguration in application class App.java:

@ComponentScan
+@EnableAutoConfiguration(exclude = {
+    ElasticsearchAutoConfiguration.class, ElasticsearchDataAutoConfiguration.class })
@EnableConfigurationProperties({ JHipsterProperties.class, LiquibaseProperties.class })
public class App {

And changed:

import org.elasticsearch.client.Client;
-import org.springframework.boot.autoconfigure.AutoConfigureAfter;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
-import org.springframework.data.elasticsearch.core.ElasticsearchTemplate;
import org.springframework.data.elasticsearch.core.EntityMapper;
import org.springframework.http.converter.json.Jackson2ObjectMapperBuilder;

import com.fasterxml.jackson.databind.DeserializationFeature;
import com.fasterxml.jackson.databind.ObjectMapper;
+import com.github.vanroy.springdata.jest.JestElasticsearchTemplate;
+import com.github.vanroy.springdata.jest.mapper.DefaultJestResultsMapper;
+import io.searchbox.client.JestClient;

@Configuration
public class ElasticSearchConfiguration {

  @Bean
-    public ElasticsearchTemplate elasticsearchTemplate(Client client, Jackson2ObjectMapperBuilder jackson2ObjectMapperBuilder) {
-        return new ElasticsearchTemplate(client, new CustomEntityMapper(jackson2ObjectMapperBuilder.createXmlMapper(false).build()));
+    public JestElasticsearchTemplate elasticsearchTemplate(JestClient client, Jackson2ObjectMapperBuilder jackson2ObjectMapperBuilder) {
+        return new JestElasticsearchTemplate(client, new DefaultJestResultsMapper(
+                new CustomEntityMapper(jackson2ObjectMapperBuilder.createXmlMapper(false).build())));
  }

Then I added configuraiton parameters, file application.yml:

+    data:
+        elasticsearch:
+            properties:
+                path:
+                  home: target/elasticsearch
+                transport:
+                  tcp:
+                      connect_timeout: 120s
        jest:
+            readTimeout: 10000
             uri: ${SEARCHBOX_SSL_URL}
