在SpringWebFlow单元测试中设置messages.properties

我知道这个问题有多老了,但找到解决办法后,我想我会把它贴给其他人:

Object obj = builderContext.getApplicationContext()
                .getBean(AbstractApplicationContext.MESSAGE_SOURCE_BEAN_NAME);
        obj = builderContext.getApplicationContext().getBean(AbstractApplicationContext.MESSAGE_SOURCE_BEAN_NAME);
        if (obj != null && obj instanceof StaticMessageSource) {
            StaticMessageSource messageSource = (StaticMessageSource) obj;
            messageSource.setUseCodeAsDefaultMessage(true);
        }

我必须创造一个 ValidationContext 在自定义web流验证程序中使用。我用反射法解决了这个问题

protected MessageSource validationMessages;

/**
 * Creates a validationContext
 * We have to use reflection because there's no way to set
   the messageSource inside {@link MockRequestContext} otherwise
 *
 * @return {@link ValidationContext}
 * @throws IllegalAccessException
 * @throws NoSuchFieldException
 */
protected ValidationContext getValidationContext() throws IllegalAccessException, NoSuchFieldException {
    final MockRequestContext requestContext = new MockRequestContext();
    requestContext.setExternalContext(context);
    final DefaultMessageContext defaultMessageContext = new DefaultMessageContext(validationMessages);
    final Field messageContextField = MockRequestContext.class.getDeclaredField("messageContext");
    final boolean accessible = messageContextField.isAccessible();
    messageContextField.setAccessible(true);
    messageContextField.set(requestContext, defaultMessageContext);
    messageContextField.setAccessible(accessible);
    return new DefaultValidationContext(requestContext, "validateInfo", mock(MappingResults.class));
}
