Any bean inyected into CustomValidator Implementation are always null. Im using Spring Boot 2, the applciation is a REST API, i'm not using MVC.
I have tried everything I have read about this with no luck so far.
this topic here for example did not work for me
Should I validate otherwise?, I've been stuck with this for 2 days already.
This is my Config class:
#Configuration
public class Beans {
#Bean
public BCryptPasswordEncoder passwordEncoder() {
return new BCryptPasswordEncoder();
}
#Bean
public MessageSource messageSource() {
ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();
messageSource.setBasename("classpath:idiomas/idioma");
messageSource.setUseCodeAsDefaultMessage(true);
messageSource.setDefaultEncoding("UTF-8");
return messageSource;
}
#Bean
public LocaleResolver localeResolver() {
AcceptHeaderLocaleResolver resolver = new AcceptHeaderLocaleResolver();
resolver.setDefaultLocale(new Locale("es"));
return resolver;
}
#Bean
public LocalValidatorFactoryBean getValidator() {
LocalValidatorFactoryBean validatorFactoryBean = new LocalValidatorFactoryBean();
validatorFactoryBean.setValidationMessageSource(messageSource());
return validatorFactoryBean;
}
#Bean
public CommonsRequestLoggingFilter logFilter() {
CommonsRequestLoggingFilter filter = new CommonsRequestLoggingFilter();
filter.setIncludeQueryString(true);
filter.setIncludePayload(true);
filter.setMaxPayloadLength(10000);
filter.setIncludeHeaders(true);
filter.setAfterMessagePrefix("REQUEST: ");
return filter;
}
}
My CustomValidator looks like this:
public class AlmacenValidator implements ConstraintValidator {
#Autowired
private AlmacenService servicio;
#Autowired
private ApplicationContext contexto;
#Override
public void initialize(AlmacenValido constraintAnnotation) {
}
#Override
public boolean isValid(Almacen item, ConstraintValidatorContext context) {
//Database calls
}
JPA Entity:
#Entity
#AlmacenValido
#Table(name = "almacenes")
public class Almacen {
//Entity fields
}
The Annotation:
#Documented
#Retention(RUNTIME)
#Target({ TYPE, FIELD, ANNOTATION_TYPE, PARAMETER })
#Constraint(validatedBy = AlmacenValidator.class)
public #interface AlmacenValido {
String message() default "{validacion.almacen}";
Class[] groups() default {};
Class[] payload() default {};
}
I've created test example for you. Please check it https://github.com/alex-petrov81/stackoverflow-answers/tree/master/validation-bean-injection

i face a litle problem with Jackson on springboot web, i'm expecting this kind of response.
{
'date': 'string of date'
}
but i get back this
[
0: java.sql.date,
1: long number of timestamp
]
please how to configure springboot to avoid this?
#Configuration
public class BootConfiguration {
#Bean
#Primary
public PasswordEncoder passwordEncoder() {
return PasswordEncoderFactories.createDelegatingPasswordEncoder();
}
#Bean
public JavaTimeModule javaTimeModule() {
return new JavaTimeModule();
}
#Bean
public Jdk8Module jdk8TimeModule() {
return new Jdk8Module();
}
#Bean
public CoreJackson2Module coreJackson2Module() {
return new CoreJackson2Module();
}
#Bean
public OAuth2AuthorizationServerJackson2Module authorizationServerJackson2Module(){
return new OAuth2AuthorizationServerJackson2Module();
}
public List<Module> securityModules(){
ClassLoader classLoader = JdbcOAuth2AuthorizationService.class.getClassLoader();
return SecurityJackson2Modules.getModules(classLoader);
}
#Bean
#Primary
#Order(Ordered.HIGHEST_PRECEDENCE)
public ObjectMapper objectMapper() {
ObjectMapper mapper = new ObjectMapper().findAndRegisterModules();
mapper.registerModule(coreJackson2Module());
mapper.registerModule(javaTimeModule());
mapper.registerModule(jdk8TimeModule());
mapper.registerModules(securityModules());
mapper.registerModule(authorizationServerJackson2Module());
mapper.addMixIn(UserPrincipal.class, Object.class);
return mapper;
}
}
this is the controller method where
#GetMapping(value = "/authentications", params = {"pge","lmt", "slug"})
public ResponseEntity<?> getLastLogins(
Authentication authentication,
#RequestParam("lmt")Integer limit,
#RequestParam("pge")Integer page,
#RequestParam("slug")String slug){
return new ResponseEntity<>(loginManager.findAllAuthentications(authentication.getName(),slug,limit,page), HttpStatus.OK);
}
}
and this is the model containing the properties i try to get back
#Data
public class User implements Serializable {
private String firstName;
private String lastName;
private Date date;
private Role role;
}
We are migrating Jersey Endpoints to Spring MVC Rest endpoints. These endpoints consumes and produces XML. But Spring MVC is unable to convert the XML input bean because XML tag and Bean's property name is different. I have to take request as String and Convert it using JAXB explicitly. Is there any better way to do that?

The following code yields null on the teamResource auto-wired object inside isValid() function:
#Component //I am not sure it is required he
public class TeamIdValidator implements ConstraintValidator<TeamIdConstraint, Integer> {
#Autowired private TeamResource teamResource;
public TeamIdValidator() {
}
#Override
public void initialize(TeamIdConstraint teamIdConstraint) {
// this.teamIdConstraint = teamIdConstraint;
}
#Override
public boolean isValid(Integer teamId, ConstraintValidatorContext cxt) {
int numOfAvailableTeams = teamResource.retrieveAllTeams().size(); //teamResource is null :(
return teamId < 0 || teamId >= numOfAvailableTeams;
}
}
TeamResource class:
#RestController
#CrossOrigin
public class TeamResource {
#Autowired private TeamRepository teamRepository;
public TeamResource() {
}
...
//mapping methods
}
And if it relevant...
#Documented
#Constraint(validatedBy = TeamIdValidator.class)
#Target({ ElementType.METHOD, ElementType.FIELD, ElementType.PARAMETER })
#Retention(RetentionPolicy.RUNTIME)
public #interface TeamIdConstraint {
String message() default "Invalid team id!";
Class<?>[] groups() default {};
Class<? extends Payload>[] payload() default {};
}
Why on earth teamResource is null?
It is not being explicitly initialized with new anywhere else.
Already mentioned in the comments but declare a a bean like this
#Configuration
public class ValidationConfig{
#Bean
public LocalValidatorFactoryBean validator() {
return new LocalValidatorFactoryBean();
}
#Bean
public MethodValidationPostProcessor methodValidationPostProcessor(Validator validator) {
MethodValidationPostProcessor methodValidationPostProcessor = new MethodValidationPostProcessor();
methodValidationPostProcessor.setValidator(validator);
return methodValidationPostProcessor;
}
}
Remove all the #autowired, prefer constructor injection. (check the internet why).
And then, it makes no sense to inject a RestContoller to validator.
I have the following sftp camel component configuration:
#Configuration
public class FtpCamelComponent {
#Value("${SFTP_HOST}")
private String sftpHost;
#Value("${SFTP_KNOWNHOST}")
private String sftpKnownHost;
#Value("${SFTP_KEY}")
private String sftpKey;
#Value("${SFTP_USER}")
private String sftpUser;
#Value("{SFTP_DIRECTORY}")
private String sftpFileDirectory;
#Bean
public SftpConfiguration sftpConfiguration(){
SftpConfiguration sftpConfiguration = new SftpConfiguration();
sftpConfiguration.setUsername(sftpUser);
sftpConfiguration.setHost(sftpHost);
sftpConfiguration.setKnownHostsFile(sftpKnownHost);
sftpConfiguration.setPrivateKeyFile(sftpKey);
sftpConfiguration.setDirectory(sftpFileDirectory);
return sftpConfiguration;
}
#Bean
public SftpEndpoint sftpEndpoint(SftpConfiguration sftpConfiguration){
SftpEndpoint sftpEndpoint = new SftpEndpoint();
sftpEndpoint.setConfiguration(sftpConfiguration);
sftpEndpoint.setEndpointUriIfNotSpecified("sftp");
return sftpEndpoint;
}
#Bean
public SftpComponent sftpComponent(SftpEndpoint sftpEndpoint){
SftpComponent sftpComponent = new SftpComponent();
sftpComponent.setEndpointClass(sftpEndpoint.getClass());
return sftpComponent;
}
}
I added the component to my camel context:
#Configuration
#Import({FtpCamelComponent.class,
SftpCamelRoute.class})
public class SftpCamelContext extends CamelConfiguration {
#Autowired
SftpComponent sftpComponent;
#Bean(name = "sftpCamelContext")
protected CamelContext createCamelContext() throws Exception {
SpringCamelContext camelContext = new SpringCamelContext();
camelContext.setApplicationContext(getApplicationContext());
camelContext.addComponent("sftp", sftpComponent);
return camelContext;
}
}
Why can't I just use sftp: in my camel route as I have already configured it and added it to my camel context?
#Bean(name = "FileToSftp")
public RouteBuilder fileToSFTP(){
return new RouteBuilder() {
public void configure() {
from("direct:fileToSftp")
.to("file:export/b1?fileName=export.csv")
.setHeader("CamelFileName", constant("export.csv"))
.to("sftp://dev#localhost:/export/in/?knownHostsFile=key/knownhost&privateKeyFile=key/id_rsa.pub&localWorkDirectory=export/b1&download=false");
}
};
}
I'm trying to override the ValidationMessages.properties from default hibernate-validation (5.0.2 version) in a Spring MVC application.
But it keeps using the internal ValidationMessages.properties from jar.
UPDATE: it works (but it should be another way) when I copy the *.properties files to org\hibernate\validator ...
This is my configuration:
#Configuration
#EnableWebMvc
#ComponentScan(basePackages = {"com.blueliv.search.*"} )
public class WebConfig extends WebMvcConfigurerAdapter {
static Logger log =LoggerFactory.getLogger(WebMvcConfigurerAdapter.class);
#Override
public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
converters.add(new GsonHttpMessageConverter());
//converters.add(new MappingJackson2HttpMessageConverter());
}
#Bean
public MethodValidationPostProcessor methodValidationPostProcessor() {
return new MethodValidationPostProcessor();
}
#Bean
public ExceptionHandlerExceptionResolver exceptionResolver() {
return new ExceptionHandlerExceptionResolver();
}
#Bean
public LocalValidatorFactoryBean validator() {
LocalValidatorFactoryBean validatorFactoryBean = new LocalValidatorFactoryBean();
validatorFactoryBean.setValidationMessageSource(getBundle());
return validatorFactoryBean;
}
public ReloadableResourceBundleMessageSource getBundle(){
log.debug("get bundle!");
ReloadableResourceBundleMessageSource bundle = new ReloadableResourceBundleMessageSource();
bundle.setBasenames("classpath:/i18n/validation/ValidatonMessages");
return bundle;
}
#Override
public Validator getValidator() {
return validator();
}
