Solr Spring boot application failed to run, giving bean error

Getting an error while running , a solr spring boot application, it says
"Parameter 0 of constructor in Controller required a bean of type Repository that could not be found."
"Consider defining a bean of type Repository in your configuration."
Here is my enitiy
#SolrDocument(collection = "content_core")
public class ContentDoc {
#Id
#Indexed
private String id;
#Indexed(name = "display_title", type = "string")
private String displayTitle;

SpringBoot 2 the elements were left unbound

i have a file application.yml with my Spring Boot application which is not willing to run.
According to logs the reason of The elements [simulator.geo.b12,simulator.geo.b13,simulator.geo.b21,simulator.geo.c6,simulator.geo.host] were left unbound. This property however is set in application.yml and compiler is even returning it's value.
I'll really appreciate if someone could lend me a hand with that issue.

this problem had confuse me long time, i hope someone can give me some advice;
i used springboot 2.0
thanks

The problem is that you are using the #ConfigurationProperties in a wrong way. You use either #ConfigurationProperties or #Value but not both.
The solution either fix your class to be usable for #ConfigurationProperties or remove the #ConfigurationProperties annotation.
#Getter
#Setter
#Component
#ConfigurationProperties(prefix = "simulator.geo",ignoreUnknownFields = false)
public class VendorSimulatorProperties {
private String host = "http://localhost:8080/";
private String b12;
private String b13;
private String b21;
private String c6;
}
You need to fix the prefix it should be simulator.geo and your properties should be named after the keys in your file. You will also require setter next to the getter. However this will also need to change the rest of your configuration, to use the newly generated getters.
For you it is probably easier to remove #ConfigurationProperties as you weren't really using them in the first place.

I got the same issue, but in my case, it's because I added #AllArgsConstructor but did not add #NoArgsConstructor. As the result, Spring was unable to create the config object (using the default constructor) so it just skips processing the configs and print out the warning.
#Getter
#Setter
#AllArgsConstructor
#NoArgsConstructor // need to add this if you have #AllArgsConstructor
public class ServerConfiguration {
private String host;
private int port;
}

Map JSON POSTed in Java Spring Rest Controller to POJO

I am sending the following JSON object to my Java Spring application
{
"ewsUrl":"https://dummy.url.com",
"ewsIdentityToken":"12345",
"itemIds":["itemids"],
"entityId":null,
"documentType":"Dummy",
"documentStatus":"Record",
"filename":"message.eml",
"metadata":{"title":"message"}
}
I have defined an object public class RequestObject and in my controller I have
public RequestObject
testMyStuff(#CurrentUser User currentUser,
#RequestBody RequestObject myDummyObject) throws Exception {
return myDummyObject
}
My application returns the error Could not read document: Root name 'ewsUrl' does not match expected ('RequestObject') for type...etc
However if I send the JSON formatted like this it successfully maps the object:
{ "RequestObject":
{
"ewsUrl":"https://dummy.url.com",
"ewsIdentityToken":"12345",
"itemIds":["itemids"],
"entityId":null,
"documentType":"Dummy",
"documentStatus":"Record",
"filename":"message.eml",
"metadata":{"title":"message"}
}
}
I do not want to name the object in my JSON, I want to send as described in the first example. How do I achieve this?
UPDATE:
RequestObject.java
public class RequestObject {
public String ewsUrl;
public String ewsIdentityToken;
public String[] itemIds;
public String entityId;
public String documentType;
public String documentStatus;
public String filename;
public Metadata metadata;
public RequestObject() {
}
public static class Metadata {
public String title;
}
}
UPDATE2:
The way it is described in this example suggests that the object does not need to be named in the JSON data in the POST request. I think I am emulating this example, but I'm getting different results.
Is there a configuration for Jackson/Spring that I am missing?
Update 3:
The complete error message is:
Failed to read HTTP message: org.springframework.http.converter.HttpMessageNotReadableException:
Could not read document:
Root name 'ewsUrl' does not match expected ('RequestObject') for type
[simple type, class uk.co.test.RequestObject] at [Source:
java.io.PushbackInputStream#7e223182; line: 2, column: 9];
nested exception is com.fasterxml.jackson.databind.JsonMappingException:
Root name 'ewsUrl' does not match expected ('RequestObject') for type
[simple type, class uk.co.test.RequestObject]

There's some configuration settings that look like they can be defined for the ObjectMapper that controls the behaviour of the root element:
https://fasterxml.github.io/jackson-databind/javadoc/2.0.0/com/fasterxml/jackson/databind/DeserializationFeature.html#UNWRAP_ROOT_VALUE - see SerializationFeature.html#WRAP_ROOT_VALUE as well.
UNWRAP_ROOT_MODULE is disabled by default according to the docs so not sure why you're seeing the behaviour you are.
Config example for spring is available at
http://docs.spring.io/spring-framework/docs/3.2.3.RELEASE/javadoc-api/org/springframework/http/converter/json/JacksonObjectMapperFactoryBean.html

Just use JSONArray instead of JSONObject
Update
You can get your Json Object via JSONArray.getJSONObject()

#ConfigurationProperties prefix not working

.yml file
cassandra:
keyspaceApp:junit
solr:
keyspaceApp:xyz
Bean
#Component
#ConfigurationProperties(prefix="cassandra")
public class CassandraClientNew {
#Value("${keyspaceApp:#null}") private String keyspaceApp;
Main method file
#EnableAutoConfiguration
#ComponentScan
#PropertySource("application.yml")
public class CommonDataApplication {
public static void main(String[] args) {
ConfigurableApplicationContext context = new SpringApplicationBuilder(CommonDataApplication.class)
.web(false).headless(true).main(CommonDataApplication.class).run(args);
}
}
TestCase
#RunWith(SpringJUnit4ClassRunner.class)
#SpringApplicationConfiguration(classes = CommonDataApplication.class)
#IntegrationTest
#EnableConfigurationProperties
public class CassandraClientTest {
#Autowired
CassandraClientNew cassandraClientNew;
#Test
public void test(){
cassandraClientNew.getSession();
System.out.println(" **** done ****");
}
}
Instead of setting junit as the keyspaceApp it sets xyz.
Looks like prefix="cassandra" not working

It looks like you are trying to use Spring Boot Typesafe Configuration Properties feature.
So in order to have it working correctly, you have to add a few changes to your code:
First of all, your CommonDataApplication class should have #EnableConfigurationProperties annotation e.g.
#EnableAutoConfiguration
#ComponentScan
#PropertySource("application.yml")
#EnableConfigurationProperties
public class CommonDataApplication {
public static void main(String[] args) {
// ...
}
}
I do not believe you need #PropertySource("application.yml") annotation as application.yml (as well as application.properties and application.xml) is a default configuration file used by Spring Boot.
Your CassandraClientNew class does not need to have #Value annotation prefixing keyspaceApp property. And your keyspaceApp has to have a setter method.
#Component
#ConfigurationProperties(prefix="cassandra")
public class CassandraClientNew {
private String keyspaceApp;
public void setKeyspaceApp(final String keyspaceApp) {
this.keyspaceApp = keyspaceApp;
}
}
BTW, if you are using List's or Sets and you initialise collections (e.g. List<String> values = new ArrayList<>();), then only getter is required. If a collection is not initialised then you need to provide a setter method too (otherwise an exception will be thrown).
I hope that will help.

General answer
1. In your properties file (application.properties or application.yml)
# In application.yaml
a:
b:
c: some_string
2. Declare your class:
#Component
#ConfigurationProperties(prefix = "a", ignoreUnknownFiels = false)
public class MyClassA {
public MyClassB theB; // This name actually does not mean anything
// It can be anything
public void setTheB(MyClassB theB) {
this.theB = theB;
}
public static MyClassB {
public String theC;
public void setTheC(String theC) {
this.theC = theC;
}
}
}
3. Declare public setters! And this is crucial!
Make sure to have these public methods declared in the above classes. Make sure they have "public" modifier.
// In MyClassA
public void setTheB(MyClassB theB) {
this.theB = theB;
}
// In MyClassB
public void setTheC(String theC) {
this.theC = theC;
}
That's it.
Final notes
The property names in your classes do not mean anything to Spring. It only uses public setters. I declared them public not to declare public getters here. Your properties may have any access modifiers.
Pay attention to the attribute "ignoreUnknownFields". Its default value is "true". When it is "false" it will throw exception if any of your properties in file "application.yml" was not bound to any class property. It will help you a lot during debugging.

I don't know where the "xyz" came from (maybe you aren't showing your whole application.yml?). You don't normally bind with #Value in #ConfigurationProperties though (it has no way of knowing what your prefix is). Did you actually #EnableCongigurationProperties anywhere? Are you using SpringApplication to create the application context?

Just add a public setter or #Setter from Lombok.

I had a similar but different issue compared to OP, and couldn't find an answer anywhere, so I'll post about it. Let say you're trying to use Lombok to go and auto generate the getters & setters & other fields for you in your configuration file.
Here is an example:
#Configuration
#ConfigurationProperties(prefix = "address")
#Data
#NoArgsConstructor
#AllArgsConstructor
#Builder
public class AddressConfig {
private Endpoint endpoint;
#Data
#NoArgsConstructor
#AllArgsConstructor
#Builder
public static class Endpoint {
private String url;
}
}
If using lombok #Getter & #Setter annotations (or #Data which also takes care of #Getter & #Setter), then make sure to also have this annotation:
#Accessors(fluent = false)
The reason: spring needs the setter methods to actually populate the configuration for you. However, in the above example, here's how the url would be set internally in spring:
addressConfig.getEndpoint().setUrl("...");
You can see that getters are prefixed with get and setters are prefixed with set.
If you do NOT have #Accessors(fluent = false) set, then the setters will use the fluent style of accessors, which don’t prepend getters with the word get and setters with the word set. This breaks springs ability to populate configuration pojos properly.
Spring will not tell you this when you execute the application. You only get null pointer exceptions when trying when your application tries to use those configuration variables. I only realized I need to put an #Accessors(fluent = false) annotation after hours of trial & error since I couldn’t find the answer on google or stackoverflow.
side note: intellij will warn you that false is the default value for #Accessors. This is wrong -_-
Anyways, here's the configuration class with the annotation (yes, you only need to add this at the top of the class, just one time, and not in the inner classes).
#Configuration
#ConfigurationProperties(prefix = "address")
#Data
#NoArgsConstructor
#AllArgsConstructor
#Builder
public class AddressConfig {
private Endpoint endpoint;
#Data
#NoArgsConstructor
#AllArgsConstructor
#Accessors(fluent = false)
#Builder
public static class Endpoint {
private String url;
}
}

That's my FULL solution for this case:
My Class will be receiving the properties:
// Setter are CRUCIAL for PropertySource + ConfigurationProperties works properly
#PropertySource(value = "classpath:application-dev.yml", ignoreResourceNotFound = true)
#ConfigurationProperties(prefix = "spring.data.mongodb")
#Setter
#Profile("dev")
#Configuration
#EnableReactiveMongoRepositories(
basePackages = {
"com.webflux.mongo2.project.repo",
"com.webflux.mongo2.task.repo"})
public class MyClassGettingTheProperties {
private String database;
private String host;
private String port;
private String username;
private String password;
private String authenticationDatabase;
}
