使用 elasticsearch 运行 Spring 引导应用程序时出现异常
Getting Exceptions while running a Spring boot app with elasticsearch
我正在学习本教程：https://www.youtube.com/watch?v=IiZZAu2Qtp0&ab_channel=LiliumCode
我所做的唯一更改是我将 maven 与 eclipse 结合使用。其余代码完全相同。当我 运行 我得到的应用程序时：

我的elasticsearch.yml:
# ======================== Elasticsearch Configuration =========================
#
# NOTE: Elasticsearch comes with reasonable defaults for most settings.
# Before you set out to tweak and tune the configuration, make sure you
# understand what are you trying to accomplish and the consequences.
#
# The primary way of configuring a node is via this file. This template lists
# the most important settings you may want to configure for a production cluster.
#
# Please consult the documentation for further information on configuration options:
# https://www.elastic.co/guide/en/elasticsearch/reference/index.html
#
# ---------------------------------- Cluster -----------------------------------
#
# Use a descriptive name for your cluster:
#
cluster.name: elastic_course
#
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
node.name: crud_node
#
# Add custom attributes to the node:
#
#node.attr.rack: r1
#
# ----------------------------------- Paths ------------------------------------
#
# Path to directory where to store the data (separate multiple locations by comma):
#
#path.data: /path/to/data
#
# Path to log files:
#
#path.logs: /path/to/logs
#
# ----------------------------------- Memory -----------------------------------
#
# Lock the memory on startup:
#
#bootstrap.memory_lock: true
#
# Make sure that the heap size is set to about half the memory available
# on the system and that the owner of the process is allowed to use this
# limit.
#
# Elasticsearch performs poorly when the system is swapping the memory.
#
# ---------------------------------- Network -----------------------------------
#
# By default Elasticsearch is only accessible on localhost. Set a different
# address here to expose this node on the network:
#
#network.host: 192.168.0.1
#
# By default Elasticsearch listens for HTTP traffic on the first free port it
# finds starting at 9200. Set a specific HTTP port here:
#
#http.port: 9200
#
# For more information, consult the network module documentation.
#
# --------------------------------- Discovery ----------------------------------
#
# Pass an initial list of hosts to perform discovery when this node is started:
# The default list of hosts is ["127.0.0.1", "[::1]"]
#
#discovery.seed_hosts: ["host1"]
#
#discovery.type: single-node
#
# Bootstrap the cluster using an initial set of master-eligible nodes:
#
#cluster.initial_master_nodes: ["node-1"]
#
# For more information, consult the discovery and cluster formation module documentation.
#
# ---------------------------------- Various -----------------------------------
#
# Allow wildcard deletion of indices:
#
#action.destructive_requires_name: false
#----------------------- BEGIN SECURITY AUTO CONFIGURATION -----------------------
#
# The following settings, TLS certificates, and keys have been automatically
# generated to configure Elasticsearch security features on 10-03-2022 10:08:43
#
# --------------------------------------------------------------------------------
# Enable security features
xpack.security.enabled: true
xpack.security.enrollment.enabled: true
# Enable encryption for HTTP API client connections, such as Kibana, Logstash, and Agents
xpack.security.http.ssl:
enabled: true
keystore.path: certs/http.p12
# Enable encryption and mutual authentication between cluster nodes
xpack.security.transport.ssl:
enabled: true
verification_mode: certificate
keystore.path: certs/transport.p12
truststore.path: certs/transport.p12
# Create a new cluster with the current node only
# Additional nodes can still join the cluster later
cluster.initial_master_nodes: ["DESKTOP-0O0S7HQ"]
# Allow HTTP API connections from localhost and local networks
# Connections are encrypted and require user authentication
http.host: [_local_, _site_]
# Allow other nodes to join the cluster from localhost and local networks
# Connections are encrypted and mutually authenticated
#transport.host: [_local_, _site_]
#----------------------- END SECURITY AUTO CONFIGURATION -------------------------
我试过在线搜索例外情况，但似乎没有任何效果。请帮我解决这个问题。谢谢。
ConnectionClosedException 似乎暗示您的 Spring 引导应用程序无法与您的 ES 集群建立连接。
您似乎在使用 ES8，它默认启用 SSL/TLS，因此您需要配置 Spring 启动应用程序以改为使用 SSL。
在 6:00 进入视频时，application.properties 中的 elasticsearch.url 应该是 https://localhost:9200 而不是 localhost:9200.
但是，截至 2022 年 3 月 15 日，似乎 ES 8 is supported by Spring Data ES 还没有，您可能需要恢复到 ES 7.15+ 版本。
我正在学习本教程：https://www.youtube.com/watch?v=IiZZAu2Qtp0&ab_channel=LiliumCode
我所做的唯一更改是我将 maven 与 eclipse 结合使用。其余代码完全相同。当我 运行 我得到的应用程序时：

我的elasticsearch.yml:
# ======================== Elasticsearch Configuration =========================
#
# NOTE: Elasticsearch comes with reasonable defaults for most settings.
# Before you set out to tweak and tune the configuration, make sure you
# understand what are you trying to accomplish and the consequences.
#
# The primary way of configuring a node is via this file. This template lists
# the most important settings you may want to configure for a production cluster.
#
# Please consult the documentation for further information on configuration options:
# https://www.elastic.co/guide/en/elasticsearch/reference/index.html
#
# ---------------------------------- Cluster -----------------------------------
#
# Use a descriptive name for your cluster:
#
cluster.name: elastic_course
#
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
node.name: crud_node
#
# Add custom attributes to the node:
#
#node.attr.rack: r1
#
# ----------------------------------- Paths ------------------------------------
#
# Path to directory where to store the data (separate multiple locations by comma):
#
#path.data: /path/to/data
#
# Path to log files:
#
#path.logs: /path/to/logs
#
# ----------------------------------- Memory -----------------------------------
#
# Lock the memory on startup:
#
#bootstrap.memory_lock: true
#
# Make sure that the heap size is set to about half the memory available
# on the system and that the owner of the process is allowed to use this
# limit.
#
# Elasticsearch performs poorly when the system is swapping the memory.
#
# ---------------------------------- Network -----------------------------------
#
# By default Elasticsearch is only accessible on localhost. Set a different
# address here to expose this node on the network:
#
#network.host: 192.168.0.1
#
# By default Elasticsearch listens for HTTP traffic on the first free port it
# finds starting at 9200. Set a specific HTTP port here:
#
#http.port: 9200
#
# For more information, consult the network module documentation.
#
# --------------------------------- Discovery ----------------------------------
#
# Pass an initial list of hosts to perform discovery when this node is started:
# The default list of hosts is ["127.0.0.1", "[::1]"]
#
#discovery.seed_hosts: ["host1"]
#
#discovery.type: single-node
#
# Bootstrap the cluster using an initial set of master-eligible nodes:
#
#cluster.initial_master_nodes: ["node-1"]
#
# For more information, consult the discovery and cluster formation module documentation.
#
# ---------------------------------- Various -----------------------------------
#
# Allow wildcard deletion of indices:
#
#action.destructive_requires_name: false
#----------------------- BEGIN SECURITY AUTO CONFIGURATION -----------------------
#
# The following settings, TLS certificates, and keys have been automatically
# generated to configure Elasticsearch security features on 10-03-2022 10:08:43
#
# --------------------------------------------------------------------------------
# Enable security features
xpack.security.enabled: true
xpack.security.enrollment.enabled: true
# Enable encryption for HTTP API client connections, such as Kibana, Logstash, and Agents
xpack.security.http.ssl:
enabled: true
keystore.path: certs/http.p12
# Enable encryption and mutual authentication between cluster nodes
xpack.security.transport.ssl:
enabled: true
verification_mode: certificate
keystore.path: certs/transport.p12
truststore.path: certs/transport.p12
# Create a new cluster with the current node only
# Additional nodes can still join the cluster later
cluster.initial_master_nodes: ["DESKTOP-0O0S7HQ"]
# Allow HTTP API connections from localhost and local networks
# Connections are encrypted and require user authentication
http.host: [_local_, _site_]
# Allow other nodes to join the cluster from localhost and local networks
# Connections are encrypted and mutually authenticated
#transport.host: [_local_, _site_]
#----------------------- END SECURITY AUTO CONFIGURATION -------------------------
我试过在线搜索例外情况，但似乎没有任何效果。请帮我解决这个问题。谢谢。
ConnectionClosedException 似乎暗示您的 Spring 引导应用程序无法与您的 ES 集群建立连接。
您似乎在使用 ES8，它默认启用 SSL/TLS，因此您需要配置 Spring 启动应用程序以改为使用 SSL。
在 6:00 进入视频时，application.properties 中的 elasticsearch.url 应该是 https://localhost:9200 而不是 localhost:9200.
但是，截至 2022 年 3 月 15 日，似乎 ES 8 is supported by Spring Data ES 还没有，您可能需要恢复到 ES 7.15+ 版本。
