There is no client authentication. Try adding an appropriate authentication filter.

[mainul35]

when I try to access /oauth/token, it shows the following error.

{
    "error": "unauthorized",
    "error_description": "There is no client authentication. Try adding an appropriate authentication filter."
}

Which version of spring boot you are using. If it's not version 2, then it should work. Just now I tried with URL - localhost:8080/oauth/token or else follow the instructions here - http://www.devglan.com/spring-security/spring-boot-security-oauth2-example

​I found the problem. It was my fault. Thanks a lot for your feedback.​

What was the solution? I have a similar issue.

[lordleebo]

I had the same problem, just make sure spring security filter is configured and running

[raulvillalbamedina]

@mainul35 what is the solution please?

[lordleebo]

Hi,

In my case the solution was to add the following lines to web.xml file to activate the security filter.

springSecurityFilterChain org.springframework.web.filter.DelegatingFilterProxy springSecurityFilterChain /*

Solved!

@xbisquerra find this in our code

`@Configuration public class SecurityConfiguration extends WebSecurityConfigurerAdapter {

@Override
public void configure(WebSecurity web) throws Exception {
    web.ignoring().antMatchers("/**");
}

}`

he change to this

`@Configuration public class SecurityConfiguration extends WebSecurityConfigurerAdapter {

@Override
public void configure(WebSecurity web) throws Exception {
    web.ignoring().antMatchers("/actuator/**");
}

}`

And all is ok, we ccall with curl to oauth/token ok, and we can use /actuator/ endpoints too.

We add to github a sample of config https://github.com/raulvillalbamedina/spring-boot-oauth2-simple

Thank you!
