B. If an embedded database is on the classpath, it will be used to configure a DataSource by default.

This is true because the @DataJpaTest annotation enables auto-configuration of an embedded database if one is available on the classpath, such as H2, HSQLDB, or Derby. This allows the test to run with a temporary and isolated database that can be configured with test data.

D. It auto-configures a TestEntityManager bean.

This is true because the @DataJpaTest annotation provides a TestEntityManager bean that can be used to perform common JPA operations in the test. The TestEntityManager is an alternative to the standard EntityManager that provides some convenience methods and exception translation.

This is true because Spring's JdbcTemplate class offers a variety of methods to execute SQL queries against a relational database. These include methods for executing SQL queries (query, queryForObject, queryForList, etc.), updates (update), and batch operations (batchUpdate).

For example: Spring Data Envers

Optional findById(ID primaryKey);

Spring Boot provides a set of tools for improving the development experience, such as automatic restart, live reload, remote debugging, etc. These tools are included in the spring-boot-starter-devtools dependency, which can be added to the project’s pom.xml or build.gradle file. The automatic restart feature will monitor the classpath for changes and trigger a restart of the application when necessary.

B. Multiple arguments can be injected into a single method using @Autowired.

This is true because the @Autowired annotation can be applied to methods with arbitrary names and multiple arguments, as shown in the example in Using @Autowired.

C. By default, if a dependency cannot be satisfied with @Autowired, Spring throws a RuntimeException.

This is true because the @Autowired annotation has a required attribute that is true by default, meaning that the dependency is mandatory. If Spring cannot find a matching bean to inject, it will throw a BeanCreationException, which is a subclass of RuntimeException. To avoid this exception, we can set the required attribute to false, which will allow Spring to skip the injection if no matching bean is found

A. @Configuration This annotation indicates that the class has @Bean definition methods and may be processed by the Spring container to generate bean definitions and service requests for those beans at runtime. B. @ComponentScan This annotation configures component scanning directives for use with @Configuration classes. Provides support parallel with Spring XML's context:component-scan element.
