Spring Boot 1.x
jar {
baseName = 'interface'
version = '0.0.1-SNAPSHOT'
manifest {
attributes 'Main-Class': 'net.pupli.sobhan.SobhanApplication'
}
}
Spring Boot 2.x
springBoot {
mainClassName = 'org.baeldung.DemoApplication'
}
or
bootJar {
mainClassName = 'org.baeldung.DemoApplication'
}
bootJar {
manifest {
attributes 'Start-Class': 'org.baeldung.DemoApplication'

In Boot 2.x, the bootJar and bootWar tasks are responsible for packaging the application.
bootJar {
baseName = 'gs-spring-boot'
version = '0.1.0'

Excluding jackson from classpath
@SpringBootApplication
@EnableAutoConfiguration(exclude = { JacksonAutoConfiguration.class })
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
Using java config
@Configuration
@EnableWebMvc
public class Application extends WebMvcConfigurerAdapter {
@Override
public void configureMessageConverters(List<HttpMessageConverter < ? >> converters) {
GsonHttpMessageConverter gsonHttpMessageConverter = new GsonHttpMessageConverter();
converters.add(gsonHttpMessageConverter);
}
}

Enabling CORS for the whole application is as simple as:
@Configuration
@EnableWebMvc
public class WebConfig extends WebMvcConfigurerAdapter {
@Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/**");
}
}
To enable CORS for the whole controller:
@CrossOrigin(origins = "http://domain2.com", maxAge = 3600)
@RestController
@RequestMapping("/account")
public class AccountController {
@RequestMapping("/{id}")
public Account retrieve(@PathVariable Long id) {
// ...
}
@RequestMapping(method = RequestMethod.DELETE, path = "/{id}")
public void remove(@PathVariable Long id) {
// ...
}
}
To enable CORS for the method:
@RestController
@RequestMapping("/account")
public class AccountController {
@CrossOrigin
@RequestMapping("/{id}")
public Account retrieve(@PathVariable Long id) {
// ...
}
}
@Component
public class SampleJob implements Job {
@Autowired
private SampleJobService jobService;
public void execute(JobExecutionContext context) throws JobExecutionException {
jobService.executeSampleJob();
}
}
@RequestMapping(value = "/", method = RequestMethod.POST)
public ResponseEntity<Car> update(@RequestBody Car car) {
...
}

To resolve this ambiguity you can use _ inside your method name to manually define traversal points. So our method name would end up like so:
List<Person> findByAddress_ZipCode(ZipCode zipCode);
