Based on your information, it need your check on your oracle jdbc connection first, especially for below part:
<!-- declare datasource -->
<bean id="dataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="oracle.jdbc.OracleDriver" />
<property name="url" value="jdbc:oracle:thin:#localhost:1521:orcl21"/>
<property name="username" value="c##gss_pos" />
<property name="password" value="sys" />
</bean>
You need ensure you can connect to your Oracle DB via the localhost:1521:orcl21 with proper user and password.

Can you also use the latest JDBC driver? You are using 11.2.0.4. Try using 21.5.0.0 or 19.14.0.0. Check out OTN page.

Error creating bean with name 'emailController'

Image of error I am receivingHello I am new to sending emails with Spring MVC. I am taking contact information in from a form and I want to be updated via email every time a new contact has been added to the database of contacts. taking in all the form parameters is working and I am able to add them to the database, but when trying to generate the email to send I am getting an Error creating bean exception. This seems to only happens when I add #Autowired to the JavaMailSender Object that I am creating in my controller. If I do not add #Autowired I get a null pointer exception probably because no object is being generated for the mail sender. Can anyone please help me how to figure this out?
I am including the code and XML files to hopefully get some insight.

I am trying to have the email send after the contact Object is added to the database. If I take #autowired off it returns a null pointer exception as if it's generating an object for sending the email.

Add below dependency in your pom and remove others I defined below should work
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-mail</artifactId>
</dependency>
and remove below:
<!-- Java Mail Dependency -->
<dependency>
<groupId>javax.mail</groupId>
<artifactId>javax.mail-api</artifactId>
<version>1.5.5</version>
</dependency>
<dependency>

<artifactId>mail</artifactId>
<version>1.4.7</version>
</dependency>
STEP2 : move out your mail properties in application.properties instead of servlet xml.
spring.mail.properties.mail.smtp.starttls.enable=true
spring.mail.host=************
spring.mail.port=587
spring.mail.username=********************
spring.mail.password=*****************
spring.mail.protocol=smtp
spring.mail.defaultEncoding=UTF-8
spring.mail.smtp.auth=true

I am trying to connect to a MongoDB database but I only obtain 404 error.
Here is my project structure: project structure

Spring MVC - No mapping found for HTTP request with URI [/demo/test] in DispatcherServlet with name 'appServlet'

I'm using Spring MVC to create a small web application. When I try to hit a URL that seems to be mapped properly in my controller, I get a 404. I'm trying to hit /projectname/test- and this is what shows in the log when I attempt to do that:
WARN : org.springframework.web.servlet.PageNotFound - No mapping found for HTTP request with URI [/demo/test] in DispatcherServlet with name 'appServlet'
I've seen a lot of similar questions being asked, but none of the suggested fixes worked for me. I'm using Spring MVC and the server can't seem to resolve the URL coming in through the browser. The strange thing is that "/projectname" works great, but "/projectname/test" won't seem to work at all. The JSPs are all in the same directory (src/main/webapp/WEB-INF/views/) with the following names:
home.jsp
test.jsp
userInfo.jsp

Any ideas? Is there more info I need to provide? Thanks!

I think the behavior you see is expected one. Your HomeController class doesn't have a mapping for /demo URI, only /user, /test and /.
UPD: After I have seen the question update, I concluded that you refer demo as a context descriptor and probably requesting it like
http://localhost:8080/demo/test
If my assumption is correct, the most probable cause of your troubles is a mismatch of context descriptor you're using in browser and the one at which application is really deployed. You may want to try accessing it like
http://localhost:8080/test
or
http://localhost:8080/appServlet/test
If that works (i.e. return "test"; is invoked) than this is the issue. If you want other application name then appServlet, you should take some actions that depend on application server you use, for example you may want to rename .war file after build, or change IDE settings if you deploy for there, and so on.

You need to add the below mapping:
<!-- DispatcherServlet Context: defines this servlet's request-processing infrastructure -->
<!-- Enables the Spring MVC #Controller programming model -->
<mvc:resources mapping="/resources/**" location="/resources/" />
<mvc:resources mapping="/resources/**" location="/resources/" />
<mvc:annotation-driven />
<!-- Handles HTTP GET requests for /resources/** by efficiently serving up static resources in the ${webappRoot}/resources directory -->
<!-- <resources mapping="/resources/**" location="/resources/" /> -->
<!-- <mvc:resources mapping="/resources/**" location="/, classpath:/META-INF/public-web-resources/"/> -->
<!-- Resolves views selected for rendering by #Controllers to .jsp resources in the /WEB-INF/views directory -->
<beans:bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<beans:property name="prefix" value="/WEB-INF/views/" />
<beans:property name="suffix" value=".jsp" />
</beans:bean>
<!-- View Handler -->
<beans:bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">
<beans:property name="favorPathExtension" value="true"/>
<beans:property name="mediaTypes">
<beans:map>
<beans:entry key="xml" value="text/xml"/>
<beans:entry key="json" value="application/json"/>
<beans:entry key="html" value="text/html"/>
<beans:entry key="less" value="text/html"/>
</beans:map>
</beans:property>
<beans:property name="viewResolvers">
<beans:list>
<beans:bean class="org.springframework.web.servlet.view.UrlBasedViewResolver">
<beans:property name="viewClass" value="org.springframework.web.servlet.view.tiles3.TilesView"/>
</beans:bean>
<beans:bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<beans:property name="prefix" value="/"/>
</beans:bean>
</beans:list>
</beans:property>
</beans:bean>

You are trying to access /demo, but as I see in your Controller, there is no such URI Template. You have root "/", "/user" and "/test".
