@EntityScan and spring.jpa.* properties can be used to customize Spring Data JPA.

Any kind of Hibernate property can be passed to Spring Data JPA like spring.jpa.properties.xxx.

Spring Data JPA is the only implementation for relational databases.

Scanning of JPA Entities can not be customized, the whole classpath is scanned.

Embedded Databases (H2, HSQLDB, Derby) are not re-created during the startup.

@Value(“#{daily.limit}”)

@Value(“$(systemProperties.daily.limit)”)

@Value(“$(daily.limit)”)

@Value(“#{systemProperties[‘daily.limit’]}”)

@Value(“#{systemProperties.daily.limit}”)

Add @PathVariable(“id”) String accountId argument to the update() handler method.

Add @PathVariable long accountId argument to the update() handler method.

Add @RequestParam long accountId argument to the update() handler method.

Add @RequestParam(“id”) String accountId argument to the update() handler method.

It auto-configures a MockMvc.

It will only scan for @Controller beans in the source code.

It is used for testing Spring MVC components such as @Controller with a running server.

Typically it is used in combination with @MockBean when there is a dependency bean to be mocked.

It is typically used with @ExtendWith(MockitoExtension.class) in JUnit 5.

It supports asynchronous non-blocking model.

It automatically supports sending and receiving Java objects.

It provides convenience methods for writing REST clients.

It provides convenience methods for writing REST services.

Sending an HTTP request with a custom header is not possible when using RestTemplate.

REST is a Protocol.

REST is Stateful.

REST is Reliable.

REST is Interoperable.

REST is Relative.

The URLs can be specified via configuration (using authorizeRequests () and request matchers), with the most specific rule first and the least specific last.

Spring Security can obtain URLs from Spring MVC controllers, the Spring Security configuration just needs a reference to the controller to be protected.

The URLs are specified in a special properties file, used by Spring Security.

The URLs can be specified via configuration (using authorizeRequests () and request matchers), with the least specific rule first and the most specific last.

@TestApplicationContext is used to define additional beans or customizations for a test.

Test methods in a @SpringBootTest class are transactional by default.

@SpringBootTest is typically used for integration testing.

Test methods annotated with @SpringBootTest will recreate the ApplicationContext.

@SpringBootTest without any configuration classes expects there is only one class annotated with @SpringBootConfiguration in the application.

A *.properties file matching the name of the class annotated with @SpringBootApplication.

config.properties or config.yml, usually located in the classpath root.

application.properties or application.yml, usually located in the classpath root.

env.properties or env.yml, usually located in the classpath root.

A Spring bean can be explicitly created by annotating methods or fields by @Autowired.

A Spring bean can be implicitly created by annotating the class with @Component and using the component-scanner to scan its package.

A Spring bean can be implicitly created by annotating the class with @Bean and using the component- scanner to scan its package.

A Spring bean can be explicitly created using @Bean annotated methods within a Spring configuration class.

A Spring bean can be explicitly created by annotating the class with @Autowired.

This syntax is invalid because the result of the getBean() method call should be cast to ClientService.

It will return a bean called ClientService regardless of its id or name.

This syntax is invalid because the bean id must be specified as a method parameter.

It will return a bean of the type ClientService regardless of its id or name.

A DataSource bean will not be auto-configured.

A JdbcTemplate bean will not be auto-configured.

A JdbcTemplate bean will be auto-configured.

A DataSource bean will be auto-configured only if a JdbcTemplate bean is explicitly defined.

A DataSource bean will be auto-configured.

Ensure a valid bean name in the @Component annotation is specified.

Ensure a valid @ComponentScan annotation in the Java configuration is specified.

Ensure a valid @Scope for the class is specified.

Ensure a valid @Bean for the class is specified.

If there is only one constructor the @Autowired annotation is not required.

Constructor injection only allows one value to be injected.

Constructor injection is preferred over field injection to support unit testing.

Construction injection can be used with multiple constructors without @Autowired annotation.

Field injection is preferred over constructor injection from a unit testing standpoint.

Allow access to a method based on user identity.

Allow access to a method based on the returned object.

Allow access to a method based on HTTP method.

Allow access to a method based on request URL.

Allow access to a method based on roles.

RESTful applications use a stateless architecture.

RESTful application use HTTP headers and status codes as a contract with the clients.

RESTful applications cannot use caching.

RESTful application servers keep track of the client state.

RESTful applications favor tight coupling between the clients and the servers.

@Value must be used for environment variables, as @ConfigurationProperties cannot access the environment.

@Value supports relaxed binding of properties, but not property binding through SpEL.

@ConfigurationProperties is preferable over @Value when type-safety during property binding is a concern.

@ConfigurationProperties only bind properties from .properties files, not from .yml files.

@ConfigurationProperties supports relaxed binding of properties, but not property binding through SpEL.
