spring security fails checking password

>PROBLEM

The security layer fails to authenticate an user without any apparent reason.


>SOLUTION
There are many possible reasons.
Among other possibilities, check:

1. Fields' length checking.
Check the fields' lengths against the model class.
They must match.

2. Check the password's field configuration.
Usually, encryptors generates encrypted strings with length=64, so the database shall provide compatible value.

spring boot: required a bean of type ... that could not be found , Consider defining a bean of type

PROCEDURE TO GUIDE YOU THROUGH HARD ISSUES ... MYSTERIOUS ONES
IN THE CONTEXT DESCRIBED HERE, AND POSSIBLY EXTENSIBLE TO OTHERS


>PROBLEM

Attempt of injecting a bean using Spring Boot and Maven fails with the following message:

Parameter 0 of method setStrongEncryptor in br.com.adr.thylab2.service.security.EncryptionSvcImpl required a bean of type 'org.jasypt.util.password.StrongPasswordEncryptor' that could not be found.
Action:
Consider defining a bean of type 'org.jasypt.util.password.StrongPasswordEncryptor' in your configuration.

>SOLUTION

1. First check your scan configuration.

Go to the class that it is used to start the app.
At @SpringBootApplication annotation check value offered to "scanBasePackages" if it contains a parent path for the class where the problem happens. Sometimes, a class becomes out of the subdirectory tree referenced by the scan value. If there isn't a parent path to the complaining class, add it.

@SpringBootApplication(scanBasePackages={"br.com.adr.thylab2", "my another package here"})

Example:

@SpringBootApplication(scanBasePackages={"br.com.adr.thylab2"})

public class Thylab2App extends SpringBootServletInitializer {

public static final String VERSION = "2.0.0-RELEASE";

@Override

protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {

return application.sources(Thylab2App.class);

}

        public static void main(String[] args) {

             SpringApplication.run(Thylab2App.class, args);

        }    

}

2. Check your @Service or @Component annotations in the related classes, those with relationships concerned to the issue.
Is it missing an annotation?
Is it annotated as it should be?

3. Is the missing bean defined?
An alternative is to supply the missing bean using a common class.
For instance:

@Configuration
public class CommonBeans {

    @Bean
    public StrongPasswordEncryptor strongEncryptor(){
        StrongPasswordEncryptor encryptor = new StrongPasswordEncryptor();
        return encryptor;
    }
}

4. Check the library versions.
For instance, if using Maven, go to pom.xml and try to update the version of the related packages, or yet, try to downgrade.
Sometimes, one library causes issues with certain versions of another ones.


5. Eventually, rollback and proceed a step-by-step checking.

If the problem still persists, the issue may be caused by more than one issue, which exception thrown on the stack may interfere with the final results to help finding the solution.
This approach is radical but very effective.

First, you make the famous "backup" of the current project. Just do it, please!
A simple copy of it is enough.
If using versioning, for instance Git or SVN, you may get a previous point prior to the introduction of the new stuff related to the issue. This is the whole point, no matter which version control system you are working with!

5a. Check if your classpath contains the necessary references.
A simple way of doing this is including some testing code that references it.
For instance, if using Spring Boot, you could simply do, like below, in a straight manner in order to skip another possible setbacks to check if your classpath is properly configured.

@SpringBootApplication(scanBasePackages={"br.com.adr.thylab2"})

public class Thylab2App extends SpringBootServletInitializer {

public static final String VERSION = "2.0.0-RELEASE";

@Override

protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {

return application.sources(Thylab2App.class);

}

  public static void main(String[] args) {

StrongPasswordEncryptor passwordEncryptor = new StrongPasswordEncryptor();

String encryptedPassword = passwordEncryptor.encryptPassword("");

             SpringApplication.run(Thylab2App.class,  args);

        }    

}

5b. Bring to the code one interface/class set at a time.
Begin with the simplest classes, bringing just one interface/class set, and testing.
Test one after the other, never more than one by its turn.
You'll probably note that this procedure will show more than one issue, but working one by one, helps the compiler to guide you to the solution.

I do sincerely hope that this "laborious and boring" procedure may help you, but surely helped me when I was desperately lost, more than once, trying to find out a mysterious issue.  :-)

spring: thymeleaf: There was an unexpected error (type=Not Found, status=404)

>PROBLEM

Pointing to URL returns 404.


Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.
Sun Jul 09 11:37:35 BRT 2017



There was an unexpected error (type=Not Found, status=404).
No message available

>SOLUTION

The web site server will typically generate a "404 Not Found" message when the resource is not found, like a broken or dead link.

So, go to the Controller class and check the right link to be used.

Attention to the detail that sometimes, the application is not configured to use an extra identification in the URL. This is the case in this example.

Usually, the app's access is done using its name, like this:

  

   http://localhost:8080/appName/index

If the configuration does not use it, then we go straight to the controller's reference, like this:

  http://localhost:8080/index

There was an unexpected error (type=Internal Server Error, status=500).
Error during execution of processor 'org.thymeleaf.spring4.processor.attr.SpringInputGeneralFieldAttrProcessor' (login)

>SOLUTION

Since the log is pointing to login, open the class which should have the respective attribute.
To find out, go to the page which is returning the error. The page may be found in the controller.
In this example we get:

@RequestMapping(value = "/", method = RequestMethod.GET)
public String addNewLogin(Login login) {
return "login";
}

Opening the page, check the object pointed by thymeleaf's "th:object" property in form tag.
In this example is "th:object="${login}".
The error message means that the parser is complaining that it was not found the attribute login for Login class.

Opening the respective Login class, you get instead of "login" the "signin" attribute.

How to fix WordPress when it stops working after plugins' updates

>PROBLEM
The scenary: the WordPress dashboard alarms that it is required to update some plugins.
Then you update the first plugin, the second, the third and suddenly the site stops working, returning code HTTP 500 or another message, and you loose access to it.
If there is no access, there is no dashboard to handle the situation.

>SOLUTION
Sometimes happens that a plugin's update conflicts with others or your site's environment, like php's version, etc.
A solution consists moving all plugins to another folder out your WordPress's folder on the server.
After that, try to access your site and in case of success you may be sure that it was a plugin conflict.
Now, we need a method to restore the plugins at the same time we discover which of them is responsible for the site's crash.

>FIXING
The idea is to move all the plugins to a temporary folder, and then, after you've gained access again to your site, you may point to the dashboard.
At the dashboard, go to plugins and installed plugins.
You'll get a page with many warnings since the plugins directory is empty.
Refresh the page, getting a blank page like that when you started your site from scratch.
Don't panic.

Now, let's discover which plugin is responsible for the issue.
Pick one plugin's folder at once and copy it back from the temporary folder to the original source's folder, for instance:

from
  /temp/akismet
to
  /public_html/yourSite//wp-content/plugins/akismet

After that, go back to your dashboard and refresh the "installed plugins" page.
The plugin is gonna appear there as usual. Activate it.
If plugin activates succesfully, go to the next.
Repeat the same procedure for each plugin until you get the one that crashes your site.
When this happens, usually you'll have to repeat the whole process again, moving out all the plugins and reintroducing one by one and testing.

The one which crashed your site will be skipped, including the future installations, until you discover the reason of the issue.
Sometimes it is due an old environment requiring update or upgrade, a more "drastic update", like php version.

In order to make the things easier when using ftp connections, you may use command line which helps to make things faster.
Here is some code snippet suggestion:

- moving all at once:
rnfr /public_html/pomar/wp-content/plugins
rnto /temp/plugins

- moving from original source place to a temporary folder:
rnfr /public_html/pomar/wp-content/plugins/akismet
rnto /temp/akismet

- moving back from the temporary folder to the original folder:
rnfr /temp/akismet
rnto /public_html/pomar/wp-content/plugins/akismet

- to create a temporary folder, do:
mkd /temp

Cygwin - Unrecognized TERM type

>PROBLEM

Type a command, for instance man or vi, the command fails with the following message:

  Unrecognized TERM type




>SOLUTION

The issue came from an attempt to switch the initial folder using "--dir" mintty's flag in the "Cygwin64 Terminal.lnk".

It was done something like this:

D:\cygwin64\bin\mintty.exe -i /Cygwin-Terminal.ico --dir  /cygdrive/D/work/devmob2_/cygwin/home/train -w max

The command above was replaced by its default (except -w flag):

D:\cygwin64\bin\mintty.exe -i /Cygwin-Terminal.ico -w max -

Instead, the initial folder was set using windows' HOME envvar.

To set windows HOME envvar:
  sysdm.cpl
Add:
  HOME=/cygdrive/l/work/devmob2_/cygwin/home

WildFly fails to start a service due to bind error - Switching port

>PROBLEM

WildFly fails to start a service throwing the following message:

>SOLUTION

Edit the following file:

  $WILDFLY_ROOTDIR\standalone\configuration\standalone.xml
  $WILDFLY_ROOTDIR\standalone\configuration\standalone-full.xml

and switch the ports:

- original value:

    <socket-binding-group name="standard-sockets" default-interface="public" port-offset="${jboss.socket.binding.port-offset:0}">
        <socket-binding name="management-http" interface="management" port="${jboss.management.http.port:9990}"/>

- new configuration using an available port:

    <socket-binding-group name="standard-sockets" default-interface="public" port-offset="${jboss.socket.binding.port-offset:0}">
        <socket-binding name="management-http" interface="management" port="${jboss.management.http.port:9991}"/>


To check if a port is currently unavailable, use netstat command.
Example:
  netstat -nao | grep 9991
If the command returns empty, the port is available (not used).

NOTE:
If using windows, you may use cygwin to make available the grep command.

"couldn't make stderr distinct from stdout" when running Cygwin commands

>SOLUTION

Check you envvars.

Originally the Path had Git's bin before cygwin64.
  Path=..;C:\Git\bin;C:\cygwin64\bin

Switching places:
  Path=..;C:\cygwin64\bin;C:\Git\bin
in order to read cygwin's library first.

In such case, you may get issues with git. So test it after your have changed the Path.

If it happens to get problems with Git, it's necessary to point git's executables manually or using a script to set the local envvar during git's execution context.

Another solution could be adopting one or another.

Apache or Node? Which one is best?

My Thoughts and Conclusions About Two Different Ways of Doing Something Concerning Server's Approaches Using Node.js vs. Apache Comparison Example

When the major problem is the number of persons to travel, matter less if the car has front-wheel drive or rear-wheel drive.
Number of seats care most.

Being straight, more requests demand more resources and increase possible concurrencies issues.
It matters less how the process requests are handled, but how the project's resources in general may scale with high availability.

Putting aside that, if you have light CPU processing per request, Node.js will be lighter approach, otherwise, if it is not possible to guarantee that, threads will fit better, so Apache is a better choice.

    'D:\work\repolib\java\mvn_repo\com\sun\tools\1.6\tools-1.6.jar'    auth        Build path    Build Path Problem

>SOLUTION

This error is caused by this dependency:

        <dependency>
            <groupId>org.jboss.as</groupId>
            <artifactId>jboss-as-jpa-hibernate3</artifactId>
            <version>7.2.0.Final</version>
        </dependency>

It was substituted by another.

>ENV
eclipse, maven, java, hibernate


>DETAILED APPROACH

A build path problem usually indicates that a dependency is missing.
So, this kind of problem may have many reasons.
First check your development tool configuration.
If Eclipse, go to preferences, Build Path. Check also Project Facets.
Go to the pom.xml and check the compilation configuration version.
It must be the same of Eclipse's configuration.

Example:

    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <configuration>
                    <source>1.6</source>
                    <target>1.6</target>
                    <encoding>UTF-8</encoding>
                </configuration>
            </plugin>
        </plugins>
    </build>

If Eclipse configuration is using version java 7, switch to 1.7 where it is 1.6.


After all this check up, if the problem remains, do the following:

1. Remove all dependencies from your pom.xml file and let it as follow:

    <dependencies>
    </dependencies>

2. Then insert the dependencies again using small groups (for instance 3 dependencies) until one of them triggers the target error.
Then isolate the dependency that causes the problem removing and test one by one in that group until the error disappears.

Spring-MVC - WARN [CglibAopProxy] Unable to proxy method

ENVIRONMENT

Spring-MVC using Spring Security.


PROBLEM

Suddenlly, the compiler begins warning:

WARN [CglibAopProxy] (CglibAopProxy.java:...) - Unable to proxy method [public final void org.springframework.web.servlet.mvc.AbstractController.setSynchronizeOnSession(boolean)] because it is final: All calls to this method via a proxy will be routed directly to the proxy.

SOLUTION

First it was commented the annotation:
  @PreAuthorize("permitAll")
on the Controller class.

Recompiled and the warns disappeared.
So, the problem comes from the procedure triggered by this annotation.

To fix, it was taken off the following attribute from "security:global-method-security" element:
  proxy-target-class="true"
on the spring-security.xml configuration.



- spring-security.xml configuration setup:

BEFORE:
    <security:global-method-security pre-post-annotations="enabled" secured-annotations="enabled"
        jsr250-annotations="enabled" proxy-target-class="true">
    </security:global-method-security>
AFTER:
    <security:global-method-security pre-post-annotations="enabled" secured-annotations="enabled"
        jsr250-annotations="enabled" >
    </security:global-method-security>

COMMENT

The proxy-target-class attribute enabled (proxy-target-class="true") forces the use of CGLIB proxying (for example, to proxy every method defined for the target object, not just those implemented by its interfaces).
However, there are some issues to consider, like the final methods that cannot be advised, as they cannot be overriden.

spring "java.lang.ClassNotFoundException: org.springframework.web.servlet.DispatcherServlet"

Problem
Running the application using eclipse's server you get the following exception:

 spring java.lang.ClassNotFoundException: org.springframework.web.servlet.DispatcherServlet  

Solution

Check if you have the spring-mvc jar in the project's classpath.
If using maven, you must have something like this in your pom.xml:

<!-- Spring 3 MVC depends on spring-core, spring-beans, spring-context, spring-web -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>${spring.version}</version>

</dependency>

If you respective reference is verified and correct, just remove the project from your server.

Perform a project clean, building everything from scratch.

Deploy the project again.

Sometimes, the eclipse's server may fail requiring a new deploy.
