How to pass an argument to errors.rejectValue() which is another property of a ResourceBundle in Spring MVC 3?
提问by Alfredo Osorio
I want to pass the ResourceBundle's (globalmessage.properties) property name "atm.number" instead of the hard-coded text "Número de cajero" as an argument of the "errors.required" property. How would I do that in a Validator?
我想传递 ResourceBundle 的 (globalmessage.properties) 属性名称“ atm.number”而不是硬编码文本“Número de cajero”作为“ errors.required”属性的参数。我将如何在验证器中做到这一点？
ReporteIncidenciaValidator (Validator):
ReporteIncidenciaValidator（验证器）：
public class ReporteIncidenciaValidator implements Validator {
public boolean supports(Class<?> clazz) {
return ReporteIncidencia.class.isAssignableFrom(clazz);
}
public void validate(Object target, Errors errors) {
ReporteIncidencia reporteIncidencia = (ReporteIncidencia) target;
if (StringUtils.isBlank(reporteIncidencia.getNumeroCajero())) {
errors.rejectValue("numeroCajero", "errors.required",
new Object[]{"Número de cajero"}, "");
}
}
}
globalmessage.properties:
globalmessage.properties:
errors.required={0} es requerido.
atm.number=Número de cajero
servlet-context.xml:

An easy way is using the ApplicationContext class
一个简单的方法是使用 ApplicationContext 类
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">
<bean id="messageSource"
class="org.springframework.context.support.ResourceBundleMessageSource">
<property name="basename">
<value>locale\messages</value>
</property>
</bean>
</beans>
public class ReporteIncidenciaValidator implements Validator, ApplicationContextAware {
private ApplicationContext ctx;
public boolean supports(Class<?> clazz) {
return ReporteIncidencia.class.isAssignableFrom(clazz);
}
public void validate(Object target, Errors errors) {
String message = context.getMessage("yourKey",
new Object[] { }, Locale.US);
// your code
}
}
