I am new to Spring Security. I have implemented Spring Security authentication and authorization at page level for my application(Like Admin only can access Admin page and normal user can't).
But now my requirement is to apply read-write authorization at field level. Some of the fields can be edited by only Admin and whereas for others it is read-only. The remaining fields in the page are common for all.
Is there any way to do solve this please let me know.
Thanks.

In my design, each user belongs to a specific group, so when a user creates an item only users from the same user group can view or edit the item, does spring security has anything to implement this scenario or I should implement it myself. I use spring oauth2 with JWT token?
Spring Security supports ACLs for Domain Objects, sounds like this might be what your after: https://docs.spring.io/spring-security/site/docs/3.0.x/reference/domain-acls.html
I am new to Spring
Problem Statement:
I have setup ldap server(Apache DS) with roles and users.
I need to authorize the same in my spring application. I need to block the urls, based on the authorization roles coming from LDAP.
How do I tell my Spring application to authorize the data coming from LDAP.
As of now it is letting me login, but on click on any of the links with the urls given to provide access I am getting access denied(403) exception.
In my knowledge I feel I need to configure the same in spring, but how do I do it, I am not able to figure out.
I am using Spring Security 3 for Authorization. By default if user does not mention any pattern in intercept url tag then Spring does not restrict that user from accessing that url. I want to restrict this default behavior of Spring Security programatically. I dont want to use denyAll in Sprig Security xml.
My requirement is whenever any Authenticated user tries to access any url,first I want to manually check whether that URL is present in Spring Security xml. If it is there then I will ask Spring to follow its normal Authorization process; but if URL is not there then I want to restrict user access for that URL. Please help me out to meet my requirement.
I tried searching in Google, but I could not find any good examples where a username and password are checked with a database for authentication purposes.
In further simple words, how can I create a simple login form using Spring and Hibernate and NOT SPRING SECURITY where the credentials are checked with the database.
Please help me creating a simple login form with just Spring 3.0 and no Spring Security 3.0. Thanks.
Simplest way to do a login form post to a Spring Controller which take username and password as parameter.
In the controller you do what ever you want to authenticate the username and password. Best is to delegate to some service layer which takes care of it.
If successfully authenticated then what you want to do? May be redirect to say home page.
Now the home page rendering should know that the user is already authenticated. This is where spring security helps.
But you can also achieve by writing a Servlet Filter where you check if user is already authenticated by checking the http session. Of course after successful login you need to store that in the session then only it will be available to the filter.
There are many other ways to achieve the same which depends upon your requirement as in what kind of security control is required.
Your solution has two parts, one of which involves Spring and another that is your code:
// DAO returns null if no such username appears in the table.
String password = userDao.findPassword(username);
boolean isValidUser = (!password.equals(null));
// Write the code to implement behavior for valid and invalid users.
If you can do a database SELECT for a password, you can do Spring authentication without Spring Security.
You may need to put that logic in an aspect that's woven in before method calls.
You may want to cache that result in session and invalidate it if a timeout is exceeded.
Form based Authentication for Spring based Application
I need to design Login page such way that Authentication upon login user and subsequent web request will validate if user is logged or not and redirect to the login page if not logged in . This is classical web application login flow. The authentication needs to be done via custom logic (application specific).
Can you provide sample Spring configuration 3.5 or working example application does this ? One approach is do login check via Web Filter and have login controller. Is there a better way doing via Spring Security model ? Any help will be greatly appreciated.
Thanks,

The default way would be to use the spring securtiy filter chain.
Spring Security has already everything to do form based authentication, the only thing you need to do is
configure it
write an jsp page (with the two input fields for user name and password)
See this create article: http://www.mularien.com/blog/2008/07/07/5-minute-guide-to-spring-security/ it explain the first steps.
And have a look at this article too: http://www.mkyong.com/spring-security/spring-security-form-login-example/ - It set some default values (urls) this make it more clear how the filters works.
