Error in running spring boot application in localhost - spring

I am a beginner at spring boot and I cannot my spring boot application on the server. I used tomcat server and IDE as eclipse. I want to run my app in browser.
My console is here

Description:
An attempt was made to call a method that does not exist. The attempt was made from the following location:
org.springframework.boot.autoconfigure.web.servlet.WebMvcAutoConfiguration$WebMvcAutoConfigurationAdapter.addResourceHandlers(WebMvcAutoConfiguration.java:339)

'org.springframework.web.servlet.config.annotation.ResourceHandlerRegistration org.springframework.web.servlet.config.annotation.ResourceHandlerRegistration.setUseLastModified(boolean)'
The method's class, org.springframework.web.servlet.config.annotation.ResourceHandlerRegistration, is available from the following locations:
jar:file:/C:/Users/Samanthika/.m2/repository/org/springframework/spring-webmvc/5.2.12.RELEASE/spring-webmvc-5.2.12.RELEASE.jar!/org/springframework/web/servlet/config/annotation/ResourceHandlerRegistration.class

Action:
Correct the classpath of your application so that it contains a single, compatible version of org.springframework.web.servlet.config.annotation.ResourceHandlerRegistration
this is my pom.xml file. hera I have added two dependencies apart from default web dependencies

import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.stereotype.Component;
#SpringBootApplication
public class FirstApp1Application {

import org.springframework.web.bind.annotation.RestController;
#RestController
public class HomeController {
#RequestMapping(value="/welcome")
public static String Welcome(){
return "Welcome to spring boot";
}
}

Just try to remove the version tag from spring-boot-starter-web dependency and remove the spring-webmvc dependency from pom.xml file.

Most probably you are using incompatible modules. This is also what the error message says:
Correct the classpath of your application so that it contains a
single, compatible version of
org.springframework.web.servlet.config.annotation.ResourceHandlerRegistration
In order to fix this go to https://start.spring.io/ and generate a project based on your needs. For an "MVC project" you only need spring-boot-starter-parent and spring-boot-starter-web; you definitely should not bring in webmvc, here's an example pom:

Based on the above line, you didn't annotate the class with #Component, IOC can't register that been

Caused by: java.lang.IllegalArgumentException: Could not resolve placeholder 'some.other.property' in value "${some.other.property}"

I am new to Spring technology and this issue has been bugging me for hours. My spring cloud config client isn't able to read properties from the config server because I am getting an IllegalArgumentException. The config server displays all the properties, but I think there is an issue with the name attribute in the propertySources list and my wild guess is that it is the reason why I am getting this issue. I am attaching the source code, error and the output here. Please help me out!!

I am getting the following output when I hit the ./{config-client-name}/{client-profile} endpoint of the spring cloud config server. The part where I think there is a problem is highlighted in yellow.

Sorry if there is any silly mistake from my end, and please do point it out if there. Thank you!
I finally found the fix myself. Seems that the client bootstrapping doesn't occur automatically in new Spring Cloud release, instead we need to add following dependency and explicitly mention the bootstrapping in bootstrap.xml in the config-client.
Add the dependency
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-bootstrap</artifactId>
</dependency>
And then I just added the following line in bootstrap.xml of my config-client and it worked magically.
spring.cloud.bootstrap.enabled=true
I got this from this link:
Spring Cloud Config: client doesn't attempt to connect to the config server:
Thank you so much guys for your help and contribution! Thanks #Bragolgirith for the fix. Hope this helps people and save their time.
“${some.other.property}” is trying searching for that property in the application.properties file and trying to inject its value in the someOtherProperty variable as expected in this portion of the code:
#Value("${some.other.property}") //from the configuration server's application.properties file
private String someOtherProperty;
Looking at your application.properties file, it is clear that no such entry named some.other.property is defined. There lies the problem, Spring is trying to inject a value not present in such file.
add "some.other.property=foo" in application.properties file and also add the following in the pom.xml:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
Today is 21st January, 2022 (spring boot version 2.6.3) and config client configuration is done through three settings:
Only add spring-cloud-starter-config dependency in your pom.xml
Set the url for config server in application.properties: spring.config.import=configserver:http://localhost:8888
Set the name of the client in order for it to fetch configuration assigned only to it: spring.application.name=movie-catalog-service
spring-cloud-starter-bootstrap dependency and bootstrap.properties are not required.
NOTE: spring-cloud.version=2021.0.0

Spring boot:connection oracle database

i'am using spring boot with oracle V11.2.0.4.0 database to develop a microservice,

Someone have an idea about this issue ?
I already download the ojdbc6.jar and use maven command to install the driver
any clue will be helpful
The problem is due to MAX_VALUE to large in All_sequence,
That's why i had this error
java.sql.SQLException: Numeric Overflow
I fixed this issue as follows:
I created a Custom class which extends Oracle10gDialect and redefined MIN_VALUE, MAX_VALUE in ALL_SEQUENCES,
Here is my class
package ibbl.lu.microservice_lims.config;
import org.hibernate.dialect.Oracle10gDialect;
public class CustomOracleDialect extends Oracle10gDialect {
#Override
public String getQuerySequencesString() {
return "SELECT SEQUENCE_OWNER, SEQUENCE_NAME,
greatest(MIN_VALUE,-9223372036854775807) MIN_VALUE,\n" +
"Least(MAX_VALUE, 9223372036854775808) MAX_VALUE,
INCREMENT_BY,CYCLE_FLAG, ORDER_FLAG, CACHE_SIZE,\n" +
"Least(greatest(LAST_NUMBER, -9223372036854775807),
9223372036854775808) LAST_NUMBER from ALL_SEQUENCES";
}
}
In the application.properties file referred to a dialect implementation
spring.jpa.properties.hibernate.dialect=ibbl.lu.microservice_lims.config.CustomOracleDialect

You are missing spring-boot-starter-web artifact. Artifact contains tells spring boot to scan the package (in which main method is present) and all his subpackage for configuration, components and controller. Since this artifact is missing, spring doesn’t register your controller and throws 404-Not found.

Spring Boot version 1.5.9 app does not open view file, not found error 404

I have a problem at displaying view file in Spring Boot with version 1.5.9 (the latest version). I created the project from Spring Initializr. I searched everywhere about the probelm in the internet. I tried many different ways but I could not make the view file displayed so I decided to ask here as the last option.

index.html file is located in src/main/resources/templates folder. I did not put it in a folder like "webapp/WEB-INF/views" because it is old and deprecated. Spring Boot handles all I presume.
You have any suggestion what else can I do? Thanks in advance.
I found the reason of not resolving view. I am writing this post for those who might have the same problem like me so they can utilize from this page. I see that there is no information regarding the problem in the internet.
I included these two modules in pom.xml
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
</dependency>
You can prefer doing it with Thymeleaf as this is not the only option.
Spring needs view resolver in order to render templates. You can add for example Thymeleaf and it should work:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
