Question

First Entity:
#Entity
#Table(name = "PIL_P_DOMAINE")
public class PIL_P_DOMAINE {
#NotBlank
#Column(nullable = false, unique = true, name = "DOMAINE_ID")
private String DOMAINE_ID;
#NotBlank
#Column(nullable = false, name = "DOMAINE_DS")
private String DOMAINE_DS;
public PIL_P_DOMAINE() {
}
}
Second Entity:
#Entity
public class PIL_P_DOMAINE_TABLE {
#NotBlank
#JoinColumn(nullable = false, name = "DOMAINE_ID")
#ManyToOne
private PIL_P_DOMAINE DOMAINE_ID;
#NotBlank
#Column(nullable = false, name = "DATABASE_NM")
private String DATABASE_NM;
#NotBlank
#Column(nullable = false, name = "TABLE_NM")
private String TABLE_NM;
#Column(name = "APPLCTN_COLNM_NM")
private String APPLCTN_COLNM_NM;
#Column(name = "CRITERE_FILTRE_NM")
private String CRITERE_FILTRE_NM;
public PIL_P_DOMAINE_TABLE() {
}
}
Converter:
#Component("domaineToDomTabConverter")
public class DomaineToDomTabConverter implements Converter<Object, PIL_P_DOMAINE> {
static final Logger logger = LoggerFactory.getLogger(DomaineToDomTabConverter.class);
#Autowired
#Qualifier("pIL_P_DOMAINE_SERVICE")
IService<PIL_P_DOMAINE> domService;
/**
*
*
* #see org.springframework.core.convert.converter.Converter#convert(java.lang.Object)
*/
public PIL_P_DOMAINE convert(Object element) {
Integer id = Integer.parseInt((String) element);
PIL_P_DOMAINE dom = domService.findById(id);
logger.info("Domaine : {}", dom);
return dom;
}
}
AppConfig:
#Configuration
#EnableWebMvc
#ComponentScan(basePackages = "com.fussa.fyby")
public class AppConfig extends WebMvcConfigurerAdapter {
#Autowired
DomaineToDomTabConverter domaineToDomTabConverter;
#Bean
public ViewResolver viewResolver() {
InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
viewResolver.setViewClass(JstlView.class);
viewResolver.setPrefix("/WEB-INF/views/");
viewResolver.setSuffix(".jsp");
return viewResolver;
}
#Override
public void addFormatters(FormatterRegistry registry) {
registry.addConverter(domaineToDomTabConverter);
}
#Bean
public MessageSource messageSource() {
ResourceBundleMessageSource messageSource = new ResourceBundleMessageSource();
messageSource.setBasename("messages");
return messageSource;
}
#Override
public void configurePathMatch(PathMatchConfigurer matcher) {
matcher.setUseRegisteredSuffixPatternMatch(true);
}
#Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
}
}
when i try to persist an PIL_P_DOMAINE object whitout adding
#Override
public void addFormatters(FormatterRegistry registry) {
registry.addConverter(domaineToDomTabConverter);
}
to my AppConfig class , to object is persisted (y).
The issue i have is when i want to persist an PIL_P_DOMAINE_TABLE object which contain an object PIL_P_DOMAINE, i added DomaineToDomTabConverter to convert to string i will get in form to the object so i added the converter in my AppCongig class,with those modifications i cant persist an PIL_P_DOMAINE object, i got this error:
WARN :
org.springframework.web.servlet.mvc.support.DefaultHandlerExceptionResolver
- Failed to bind request element: org.springframework.beans.TypeMismatchException: Failed to convert
value of type [com.fussa.fyby.model.PIL_P_DOMAINE] to required type

is java.lang.ClassCastExce ption: com.fussa.fyby.model.PIL_P_DOMAINE
cannot be cast to java.lang.String
How can i call the converter only if i want to persist my second entity and not the first ?
Thanks for any advices..

Answer 1

This issue was fixed by Parameterizing the type i'm converting from to String instead of Object
#Component("domaineToDomTabConverter")
public class DomaineToDomTabConverter implements Converter<String, PIL_P_DOMAINE> {
public PIL_P_DOMAINE convert(Stringelement) {
//
}
}
