The project is using Spring Boot, some of the pom.xml it's showing below

    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.0.2.RELEASE</version>

    <dependency>
        <groupId>org.mybatis.spring.boot</groupId>
        <artifactId>mybatis-spring-boot-starter</artifactId>
        <version>1.2.0</version>
    </dependency>
    <dependency>
        <groupId>org.mybatis.spring.boot</groupId>
        <artifactId>mybatis-spring-boot-starter-test</artifactId>
        <version>1.3.2</version>
        <scope>test</scope>
    </dependency>

My problem is similar to this one. I checked its description, the member of Mybatis suggest add @AutoConfigureMybatis if want an integration test. However, I just want to test the controller. And in another issue, it's also talking about something other than controller test.

One of my tests can pass successfully, but other throw an exception on

Caused by: java.lang.IllegalArgumentException: Property 'sqlSessionFactory' or 'sqlSessionTemplate' are required

If I remove the @AutoConfigureMybatis annotation and the @AutoWired ApplicationContext.The passed test will fail on the following exception.

java.lang.IllegalStateException: Failed to load ApplicationContext

The stack trace information shows the test it's trying to use the real database access information. However, get request test in the same class passed. Not sure how AutoConfigureMybatis work, and what's the cause of my problem.

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.springframework.transaction.CannotCreateTransactionException: Could not open JDBC Connection for transaction; nested exception is java.sql.SQLException: Access denied for user 'root'@'localhost' (using password: YES)

The problem is that you have Transactional annotation on your controller methods (and most probably this is not the case for the get method you mentioned).

You mocked calls to service but the transaction management is still on and is applied to the controller so spring tries to create a transaction before calling the method.

Usually service methods are marked as Transactional and if you do this you will not have this problem.
