I am trying to build an web application using Spring Boot and Spring Security.I am submitting a form with POST method as an admin to add some details into database but everytime I hit that submit button it shows the error page.I have added all the dependencies .The registration and login page works fine What am I suppose to do here?
Related
I am having an issue where the custom login page doesn't appear to be working properly. It sends me to the login?error url, rather than the index page. When using the default Spring Security page, it works exactly as intended. I have placed the code below for the html page and the code dealing with the security and custom page in general.
I'm also using a postgresql database if that's somehow involved here.

You forgot to include the name attribute on your username input.
Been at this all day. I may be missing an annotation somewhere. I also cannot get this app to serve the index.html.
What am I missing here? The primary issue is not being able to get the form to submit anything to the backend. Is ModelAttribute correct?
Thanks in advance.

Before demanding an Object from Thymeleaf you have to create and pass one there. Thymeleaf won't create an object for you.
You need to pass the object via Model to the Controller like so:
#ModelAttribute("course")
public Course course() {
return new Course();
}
You need to make sure Course object has getters, setters and default constructor for Thymeleaf to be able to work with it correctly.
I am working on a spring-boot project which includes thymeleaf, spring-security. It works fine when I perform - showing products-list, showing products-details, adding new product, updating existing product.
But when I perform - deleting an product, it gives the following ERROR:
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Forbidden, status=403).

fortunately you add "modal" inside thymeleaf each loop, so edit your html from according my code ....
<form id="deleteForm" th:action="${'/products/delete/' + theProductId}" th:method="DELETE">
<button type="submit" class="btn btn-danger">Delete Employee</button>
</form>
this is tested code ...working fine ..
you just miss "th:action" for that it dose not work as thymeleaf form. so thymeleaf dose not provide hidden "_csrf" field;
Try disabling csrf token in your configuration:
#Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests()
.antMatchers("/css/**")
.permitAll()
.antMatchers("/js/**")
.permitAll()
.anyRequest()
.authenticated()
.and()
.formLogin()
.loginPage("/login")
.loginProcessingUrl("/authenticateTheUser")
.permitAll()
.and()
.logout()
.permitAll()
.and().csrf().disable();
}
I know there are many threads on this topic i have tried most of them, still cant fix my problem.I am using SpringMVC and MongoDB What i am trying to achieve is, I will Store some data in database and then i will retrieve it back from data base to a select options. here is my codes.

public List<Category> categoryList() {

}
Class to map categoryOptions
public class Referrals {
private String categoryOptions;
public String getCategoryOptions() {
return categoryOptions;
}
public void setCategoryOptions(String categoryOptions) {
this.categoryOptions = categoryOptions;
}
}
and I am getting this error log
Servlet.service() for servlet [spring-dispatcher] in context with path [/LoginMavenSpringMVC] threw exception [An exception occurred processing JSP page /WEB-INF/views/referralPage.jsp at line 366

Stacktrace:] with root cause
java.lang.IllegalStateException: Neither BindingResult nor plain target object for bean name 'categoryOptions' available as request attribute
Where I am getting wrong? I have tried solutions from different question but couldn't solve it.
You are missing adding Referrals object to model.
#RequestMapping(value="/saveReferral", method=RequestMethod.POST)
public ModelAndView save(#ModelAttribute("saveReferral") Referrals referral){
ModelAndView model=new ModelAndView("referralPage");
model.addAttribute("categoryOptions",new Referrals()); //or referral
return model;
}
Exception is occuring because of <f:select path="categoryOptions">,you have mentioned categoryOptions in path but no where you are returning to this jsp with categoryOptions.
Update : So this says whenever you are loading referral jsp, you have to load with categoryOptions bean
And in below lines list is added to model using model.addObject() but path variable categoryOptions is missing. So after the line model.addObject("list", list); add model.addAttribute("categoryOptions", new Referrals());
<f:select path="categoryOptions">
<f:options items="${list}"/>
</f:select>
I am beginning to study AngularJS with Spring MVC and I wanted when I entered the system in the case http: // localhost: 8080 / he entered a home page that is called index.html, walked snooping on the Internet, most could not succeed in time to call the page.
This is my controller that just created to call the page as in the examples I've seen too.
package br.com.escconsultoria.standard.controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.servlet.ModelAndView;
#RestController
#RequestMapping(value = "/")
public class IndexController {
#RequestMapping(method = RequestMethod.GET)
public ModelAndView getIndexPage() {
return new ModelAndView("/index");
}
}
Beauty of this fine examples simply doing: it returns index, worked over my could not for nothing there I saw talking about using Template: Thymeleaf only that I could not even now he does not think where's the page.

registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
registry.addResourceHandler("/templates/**").addResourceLocations("/templates/");
}
}
Does anyone have an idea how to implement it?
My index page is in the scr/main/resources/templates/index.html
Solution:
Good I managed to solve my problem and I am putting the solution here, first the first thing that kept me from work was the Controller noted with RestController and needed to be only Controller.
#Controller
#RequestMapping(value = "/")
public class IndexController {
#RequestMapping(method = RequestMethod.GET)
public String getIndexPage() {
return "index3";
}
}
And according to my App Configuration it looked like this.
package br.com.escconsultoria.standard.configuration;
import org.springframework.context.MessageSource;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.support.ResourceBundleMessageSource;
import org.springframework.web.multipart.commons.CommonsMultipartResolver;
import org.springframework.web.servlet.ViewResolver;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import org.springframework.web.servlet.view.InternalResourceViewResolver;
#Configuration
#EnableWebMvc
#ComponentScan(basePackages = {"br.com.escconsultoria.standard.configuration",
"br.com.escconsultoria.standard.controller",
"br.com.escconsultoria.standard.repository",
"br.com.escconsultoria.standard.service",
"br.com.escconsultoria.imobiliario.controller",
"br.com.escconsultoria.imobiliario.repository",
"br.com.escconsultoria.imobiliario.service"})
public class AppConfiguration extends WebMvcConfigurerAdapter{
#Bean
public ViewResolver viewResolver() {
InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
viewResolver.setPrefix("/templates/");
viewResolver.setSuffix(".html");
viewResolver.setCache(false);
return viewResolver;
}
#Bean
public CommonsMultipartResolver multipartResolver() {
CommonsMultipartResolver multipartResolver = new CommonsMultipartResolver();
multipartResolver.setMaxUploadSize(100000l);
return multipartResolver;
}
#Bean
public MessageSource messageSource() {
ResourceBundleMessageSource messageSource = new ResourceBundleMessageSource();
messageSource.setBasename("messages");
return messageSource;
}
#Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/app/**").addResourceLocations("/app/");
registry.addResourceHandler("/assets/**").addResourceLocations("/assets/");
registry.addResourceHandler("/static/**").addResourceLocations("/static/");
registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
registry.addResourceHandler("/templates/**").addResourceLocations("/templates/");
}
}
Then I had a little problem in the index that I was trying to do more was because they were generating in Pingendo and he did not close the tag in the case of the target, input and some other was not close at hand and it worked. My Test HTML below.
