Q:

Spring MockMvc Passing Nested Form Parameters

I have the following form
public class MyForm {
private Account account;
}

public class Account {
private String firstName;
}

How do I pass firstName parameter?
(The following approach does not work)
mockMvc.perform(post("/xyz")
                .param("account.firstName", "John"))
                .andExpect(model().hasErrors())
                .andExpect(view().name("/xyz"))
                .andExpect(status().isOk())

A:

Finally I resolved this issue. Since I am using standalone setup I had to define validator and messagesource.
void setupTest() {
        MockitoAnnotations.initMocks(this)

        this.mockMvc = MockMvcBuilders.standaloneSetup(getController())
                .setValidator(getValidator())
                .alwaysDo(MockMvcResultHandlers.print())
                .build()
    }

    private MessageSource getMessageSource() {
        ResourceBundleMessageSource messageSource = new ResourceBundleMessageSource();

        messageSource.setBasename("messages");
        messageSource.setUseCodeAsDefaultMessage(true);

        return messageSource;
    }

    private LocalValidatorFactoryBean getValidator() {
        def validator = new LocalValidatorFactoryBean()
        validator.setValidationMessageSource(getMessageSource());

        return validator;
    }
