Question 16

Refer to the exhibit.

The above code shows a conditional @Bean method for the creation of a JdbcTemplate bean.

Which two statements correctly describe the code behavior? (Choose two.)

@ConditionalOnBean(name= “dataSource”) should be replaced with @ConditionalOnBean (DataSource.class) for greater flexibility.

@ConditionalOnBean(name= “dataSource”) should be replaced with @ConditionalOnMissingBean (DataSource.class) for greater flexibility.

The @Bean annotation should be removed.

A JdbcTemplate bean will be created when the DataSource class is in the classpath but there is no DataSource bean.

A JdbcTemplate bean will be created when a bean named dataSource has already been created.

Correct Answer: A, E

The @ConditionalOnBean annotation used in the code ensures that the JdbcTemplate bean will only be created if a bean named 'dataSource' already exists in the application context. This behavior is correctly described by the statement that a JdbcTemplate bean will be created when a bean named dataSource has already been created. Additionally, replacing @ConditionalOnBean(name= “dataSource”) with @ConditionalOnBean(DataSource.class) provides greater flexibility because it checks for the existence of a DataSource bean of any name in the context, rather than a bean with a specific name, making the code more adaptable.

Discussion

A and E Option D is incorrect because the @ConditionalOnBean annotation requires that a bean with the specified name or class already exists in the application context for the JdbcTemplate bean to be created.
