I was following this tutorial: https://www.youtube.com/watch?v=IiZZAu2Qtp0&ab_channel=LiliumCode
and the only changes I made were that I was using maven with eclipse instead. The rest of the code is exactly the same. When I run the app I get:
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'personController' defined in file [D:\Java Programs\Spring\elasticsearch\target\classes\com\elastic\elasticsearch\controller\PersonController.class]: Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'personService' defined in file [D:\Java Programs\Spring\elasticsearch\target\classes\com\elastic\elasticsearch\service\PersonService.class]: Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'personRepository' defined in com.elastic.elasticsearch.repository.PersonRepository defined in @EnableElasticsearchRepositories declared on Config: Invocation of init method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.data.elasticsearch.repository.support.SimpleElasticsearchRepository]: Constructor threw exception; nested exception is org.springframework.data.elasticsearch.UncategorizedElasticsearchException: java.util.concurrent.ExecutionException: org.apache.http.ConnectionClosedException: Connection is closed; nested exception is ElasticsearchException[java.util.concurrent.ExecutionException: org.apache.http.ConnectionClosedException: Connection is closed]; nested: ExecutionException[org.apache.http.ConnectionClosedException: Connection is closed]; nested: ConnectionClosedException[Connection is closed];

My 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 -------------------------
I have tried out searching the exceptions online but nothing seems to work. Please help me in figuring this out. Thank you.
CodePudding user response：
ConnectionClosedException seems to hint at the fact that your Spring Boot application cannot establish a connection to your ES cluster.
It looks like you're using ES8, which has SSL/TLS on by default, so you would need to configure your Spring Boot application to use SSL instead.
At 6:00 into the video, elasticsearch.url in application.properties should be https://localhost:9200 instead of just localhost:9200.
However, as of March 15th 2022, it doesn't seem like ES 8 is supported by Spring Data ES yet, you might need to revert to the ES 7.15 release.
