use multiple ldaptemplates with different ldap directories

It is possible to use multiple databases with spring data with jpa. I would like the same ability with spring ldap (ldaptemplate) and multiple ldap directories.

Why don't you have a list injected and iterate over? This is what I did for at least a year and it served me well.

[mar1ged]

I am not sure what you mean or how this could look like. Can you share a code snippet ?

[michael-o]

Use method injection with:

@Autowired
public void setContextSources(List<ContextSource> sources) {
  for (ContextSource source : sources)
    this.ldapTemplates.add(new LdapTemplate(source));
}

Perhaps I didn't yet wrap my head around this, but where should I wire this in and where should I provide the credentials and the other stuff for the context sources ?

If you want to have a look I described more of what I am searching for in this SO post: https://stackoverflow.com/questions/52521083/configure-a-second-independent-ldaptemplate-for-spring-boot

This happens in your DAO/Repository/Service. The context sources are created in your beans.xml or in App config via Java.

When i call this methd in a class like this it's ldapTemplate has value but findAllByName() return 0!!!!If i remove the first ldapConfigUration and it's ldapTemplate,the findAllByName() for User work well!! please help me!Thanks!

//first ldapConfig
@Configuration
public class LdapConfiguration  {

    @Value("${spring.ldap.urls}")
    private String url;

    @Value("${spring.ldap.username}")
    private String userName;

    @Value("${spring.ldap.base}")
    private String base;

    @Value("${spring.ldap.password}")
    private String password;

    @Bean
    public LdapContextSource contextSource(){
        LdapContextSource contextSource = new LdapContextSource();
        contextSource.setBase(base);
        contextSource.setPassword(password);
        contextSource.setUrl(url);
        contextSource.setUserDn(userName);
        return contextSource;
    }

    @Bean
    public LdapTemplate ldapTemplate(LdapContextSource ldapContextSource){
        return new LdapTemplate(ldapContextSource);
    }


//second ldapConfiguration
@Configuration
@EnableLdapRepositories(basePackages = "com.example.batch.repository", ldapTemplateRef="userLdapTemplate")

        return contextSource;
    }

    @Bean("userLdapTemplate")
    public LdapTemplate userLdapTemplate(LdapContextSource ldapContextSource){
        return new LdapTemplate(ldapContextSource);
    }


//UserLdapRepository
@Repository

    List<User> findAllByName(String name);

//User Object class
