spring boot mongodb xml configuration - spring

I'm trying to configure mongoClient using xml configuration in a spring boot application.
Caused by: java.lang.IllegalStateException: Cannot convert value of type 'java.lang.String' to required type 'com.mongodb.MongoCredential' for property 'credentials[0]': no matching editors or conversion strategy found

Spring Configuration file:

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<mongo:mongo-client id="mongoClient" credentials="user:password#testdb"></mongo:mongo-client>
</beans>
The spring-data-mongodb documentation also mentions about the credentials field in xml configuration. Not sure if I'm missing any dependencies or should I have to add some custom mapping converters.

exception in loading bean in Springboot application

We are trying to convert a standalone spring-hibernate based application to web application using Springboot(STS 4). We are using applicationcontext.xml file for bean creation and configuration.We configured libraries in pom.xml,which is attached here. When running the application using Maven, following error is showing. Please help
Description:
An attempt was made to call a method that does not exist. The attempt was made from the following location:

</dependency>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
</dependency>
When you add the jpa dependency to your project it will try to wire a dataSource bean. You will need to provide adequate properties for this bean to be configured or your project startup will fail.
Your properties file should look something like this:
spring.datasource.url=jdbc:mysql://localhost:3306/yourDBname
spring.datasource.username=root
spring.datasource.password=pass
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.jpa.database-platform=org.hibernate.dialect.MySQL5InnoDBDialect
Mind that this db should exist in your MySQL instance.

Unable to create a simple spring Boot Gateway api

I am trying to create a simple spring boot Gateway project. Below is the POM.xml for the same. When the dependencies are loaded it shows it has an error. On verification, I found the gateway jar is not getting loaded. I tried to update the maven project and even refresh but nothing is working.
Error: Could not find or load main class photoappGateway.GatewayApplication Caused by: java.lang.ClassNotFoundException: photoappGateway.GatewayApplication
Can you help me to understand what I am doing wrong or where I am making mistake?
Also I am able to create a simple app with web,eureka client dependency. That one works fine.

How to fix: java.lang.NoSuchMethodError: r: org.springframework.util.ReflectionUtils.accessibleConstructor

I´m setting up a new weblogic server to deploy and spring + angular application.
When I deploy it, server return the following error:
java.lang.NoSuchMethodError: org.springframework.util.ReflectionUtils.accessibleConstructor(Ljava/lang/Class;[Ljava/lang/Class;)Ljava/lang/reflect/Constructor;
org.springframework.util.ReflectionUtils.accessibleConstructor(Ljava/lang/Class;[Ljava/lang/Class;)Ljava/lang/reflect/Constructor;
I'm using a weblogic 12c with java 8 to deploy the application. I checked that probably it's a problem with different versions of dependencies in a module. But I didn't found any problem on it.
This is the pom of my spring boot application:

I don´t know if anyone can help me to deploy this application correctly.
Updated
This is my weblogic.xml
<?xml version="1.0" encoding="UTF-8"?>
<weblogic-version>12.2.1</weblogic-version>
<context-root>/dgfdg-backend</context-root>
<container-descriptor>

<prefer-web-inf-classes>true</prefer-web-inf-classes>
<show-archived-real-path-enabled>true</show-archived-real-path-enabled>
</container-descriptor>
I used "prefer-web-inf-classes" to true, to avoid problems with my customs jar. I can't use "prefer-application-packages" with "prefer-web-inf-classes", they are incompatible.
SOLVED
Finally, I can resolve my problem. It was the way I created one of my own libraries that I used in my web service.
I was using it like an artifact but I need to create the jar using maven commands.
After create the library using "mvn clean package" and put it in my web service, I can deploy it without any problem.
The exception tell you that there is a class that doesn't have the default constructor without any parameter. Jackson library has problems with Weblogic and Spring.
Example of weblogic.xml file:
<?xml version="1.0" encoding="UTF-8"?>
<weblogic-web-app xmlns="http://xmlns.oracle.com/weblogic/weblogic-web-app"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<prefer-application-packages>
<package-name>com.fasterxml.jackson.*</package-name>
</prefer-application-packages>
</container-descriptor>
<context-root>/</context-root>
</weblogic-web-app>
I can help you with the setup, I was developing applications with Weblogic 12.2.1.2 and JDK 8, I don't have any problem.

Missing spring boot dependency 'spring-integration-mail'

In my Spring Boot (2.1.6.RELEASE) project I have added following dependencies:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-integration</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-mail</artifactId>

But still the following is missing spring-integration-mail, should it not be included automatically?

The integration starter only pulls in the spring-integration-core jar; otherwise you would have many unnecessary jars on your classpath, slowing your application startup.
The mail starter does not know anything about spring integration; it is for when you want to use mail without spring integration
You need to add other integration modules manually:
<dependency>
<groupId>org.springframework.integration</groupId>
<artifactId>spring-integration-mail</artifactId>
</dependency>
The version will be managed for you.
