Spring boot maven multi module project with Spring Data

Question

I have a spring boot(1.4.3.RELEASE) application with MySQL as a backend. Using Spring Data with Oracle UCP and MySQL Java connection for connection pooling. Now, trying to move it to a multi module project. Hence my project structure is as follows.

parent project
|---pom.xml  -> This is a parent pom.
|---common
    |---pom.xml
    |---src
|---model
    |---pom.xml
    |---src
|---service(Interface only)
    |---pom.xml
    |---src
|---service Impl(Implementations only)
    |---pom.xml
    |---src
|---repository(Spring Data)
    |---pom.xml
    |---src
|---web
    |---pom.xml
    |---src

My parent pom.xml is as follows:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0

Application.java in web:

@SpringBootApplication(scanBasePackages =

    </dependency>

In my repository pom.xml, I have spring-data

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>

My DataSource code and the repositories are there in repository project. I have my Spring security code in web module which uses Service module thru injection.

I am getting the below error when i start my web module application.

Error creating bean with name 'webSecurityConfig': Unsatisfied dependency expressed through field 'userDetailsService'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'userDetailsService': Unsatisfied dependency expressed through field 'userService'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.cc.test.db.service.UserService' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

Is there any other config missing.

Beans in the service impl module is not getting discovered when starting.

Thanks

Answer 1

Package com.cc.test.db.service is not scanned according to your configuration.

Add it.

Your annotation should look like this:

@SpringBootApplication(scanBasePackages = 
            { "com.test.dbrepo.service.impl", "com.test.db.service", "com.test.dbrepo.repository", "com.cc.test.db.service" })
