public org.restlet.Component restletComponent() {

}
#Bean
public RestletComponent restletComponentService() {

}
I load file using postman and app stores file inside the folder rest_files
But content of file and its name looks strange.
file name: ID-username-1508923387747-0-2
content:
How to make it to store at least correct content?

Can we implement it using YamlMapFactoryBean. Have not been able to find its working demonstration.
I have a SpringBoot Kafka streams maven app. I use a spring-boot-starter-parent 2.4.4 for my springboot dependencies and kafka-streams 2.7.0.

I am not sure if I am missing any context when Autowiring my ConfigProps class or if I need further annotations on my test class.
For JUnit4 you need #Runwith(SpringJUnit4ClassRunner.class) alongside the #ContextConfiguration.
For JUnit5, use #SpringJUnitConfig.
For proper loading of properties, though, you need #SpringBootTest.
Boot 2.4 uses JUnit5.
And you should not have #ConfigurationProperties on the test.
EDIT
I just tested it with no problems.

After adding it, I ran into 2 issues:
A PUT request with nested JSON gives below error

I comment out the CORS configuration and everything works fine.

I try to replace #Component to #Configuration but still doesn't works.
I don't need 'fieldValidation' in Logout class or another class be a null value.
package xxx.converter;
import java.lang.reflect.Field;
import java.math.BigDecimal;
import java.text.SimpleDateFormat;
import java.time.LocalDate;
import java.time.Year;
import java.time.YearMonth;
import java.time.format.DateTimeFormatter;
import java.time.format.DateTimeParseException;
import java.time.format.ResolverStyle;
import java.util.Date;
import java.util.List;
import java.util.Locale;
import org.springframework.context.annotation.Configuration;
import org.apache.commons.beanutils.BeanUtils;
import org.apache.commons.validator.routines.BigDecimalValidator;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.PropertySource;
import org.springframework.context.support.PropertySourcesPlaceholderConfigurer;
import com.fasterxml.jackson.databind.ObjectMapper;
import xxx.exception.common.ErrorException;
#Configuration
#PropertySource("file:${layout.properties_file}")
public class FieldValidation {
public void validateObject(Object objResponse, String config) throws Exception {
try {
List<Configuration> confs = objectMapper.readValue(config,
objectMapper.getTypeFactory().constructCollectionType(List.class, Configuration.class));
for (int i = 0; i < confs.size(); i++) {
Configuration configuration = confs.get(i);
Object objValue = getValue(configuration.getFieldName(), objResponse);
Validation validation = new Validation();
BeanUtils.copyProperties(validation, configuration);
isValid(objValue, validation);
if (configuration.getType().equalsIgnoreCase("object")) {
List<Validation> validations = configuration.getValidation();
Class<?> act = Class.forName(configuration.getClassName());
Object objectConfig = act.cast(objValue);
validateObject(objectConfig, validations);
}
}
} catch (Exception e) {
throw e;
}
}
This is full import of FieldValidation class and replace #Configuration and I get this error.
configuration.getFieldName() << error The method is undefined for type Configuration
configuration.getType() << error The method is undefined for type Configuration
configuration.getValidation() << error The method is undefined for type Configuration
configuration.getClassName() << error The method is undefined for type Configuration
I'm quite new to Spring and I have created a small webservice with Spring-boot, Hibernate and Swagger. Here is my HomeController:
package io.swagger.configuration;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
/**
* Home redirection to swagger api documentation
*/
#Controller
public class HomeController {
#RequestMapping(value = "/")
public String index() {
System.out.println("swagger-ui.html");
return "redirect:swagger-ui.html";
}
}
Everything is working well, excepting I don't understand why when I have an Internal Server Error I get a status 200 with this body for example:
{
"timestamp": "2017-12-12T23:52:02.306+0000",
"status": 500,
"error": "Internal Server Error",
"exception": "javax.persistence.PersistenceException",
"message": "org.hibernate.exception.ConstraintViolationException: could not execute statement",
"path": "/example/members/1031/subscriptions"
}
And there is the launcher :
package io.swagger;
import org.apache.commons.logging.LogFactory;
import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.ExitCodeGenerator;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.context.web.SpringBootServletInitializer;
import org.springframework.context.annotation.ComponentScan;
import springfox.documentation.swagger2.annotations.EnableSwagger2;
#SpringBootApplication
#EnableSwagger2
#ComponentScan(basePackages = "io.swagger")
public class Swagger2SpringBoot extends SpringBootServletInitializer implements CommandLineRunner {
#Override
public void run(String... arg0) throws Exception {
if (arg0.length > 0 && arg0[0].equals("exitcode")) {
throw new ExitException();
}
}
public static void main(String[] args) throws Exception {
LogFactory.getLog(Swagger2SpringBoot.class).warn("test");
new SpringApplication(Swagger2SpringBoot.class).run(args);
}
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Swagger2SpringBoot.class);
}
class ExitException extends RuntimeException implements ExitCodeGenerator {
private static final long serialVersionUID = 1L;
#Override
public int getExitCode() {
return 10;
}
}
}
with the configuration :
package io.swagger;
import java.util.List;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.converter.HttpMessageConverter;
import org.springframework.http.converter.json.MappingJackson2HttpMessageConverter;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.SerializationFeature;
#Configuration
public class WebConfiguration extends WebMvcConfigurerAdapter {
/**
* Make sure dates are serialised in
* ISO-8601 format instead as timestamps
*/
#Override
public void extendMessageConverters(List<HttpMessageConverter<?>> converters) {
for (HttpMessageConverter<?> converter : converters) {
if (converter instanceof MappingJackson2HttpMessageConverter) {
MappingJackson2HttpMessageConverter jsonMessageConverter = (MappingJackson2HttpMessageConverter) converter;
ObjectMapper objectMapper = jsonMessageConverter.getObjectMapper();
objectMapper.disable(
SerializationFeature.WRITE_DATES_AS_TIMESTAMPS
);
break;
}
}
}
}
Another one for Swagger:
package io.swagger.configuration;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.service.Contact;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
#Configuration
public class SwaggerDocumentationConfig {
ApiInfo apiInfo() {
return new ApiInfoBuilder().title("**** API").description("No description").license("").licenseUrl("")
.termsOfServiceUrl("www.****.com").version("1.0.0")
.contact(new Contact("", "", "****#****.com")).build();
}
#Bean
public Docket customImplementation() {
return new Docket(DocumentationType.SWAGGER_2).select()
.apis(RequestHandlerSelectors.basePackage("io.swagger.api")).build().apiInfo(apiInfo());
}
}
So why do I have this 200 status if I got a server error? At least I'd like to generate a status 500, 200 means everything was fine, and obviously it's not. Any idea ?
It appears I had implemented a custom error controller generating code from my swagger file, I deleted it and now everything is ok.
