Spring引导方式做LDAP认证

Question

I have the following working codes that can authenticate a user with LDAP. As you can see, it's very simple. But how can I do the same thing the Spring Boot way?

     try {
            Hashtable<String, Object> env = new Hashtable<>();
            env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
            env.put(Context.PROVIDER_URL, “ldaps://xxxxxxxx.abcgroup.xyz.com:636”);
            env.put(Context.SECURITY_AUTHENTICATION, "simple"); // fixed value
            env.put(Context.SECURITY_PRINCIPAL, “myid@abcgroup.xyz.com”);
            env.put(Context.SECURITY_CREDENTIALS, "mypassword");
            new InitialDirContext(env);
           // authentication successful.
      } catch (Exception exception) {
           // authentication failed.
      }

Firstly you should write your Connection information in a Configuration file,for example a ldap.yml file.

ldap:
  url: ldap://XXXXXXX:389/
  root: cn=root,dc=root,dc=com
  userDn: cn=root,dc=root,dc=com
  password: XXXXXX
  baseDN: dc=root,dc=com
  clean: true
  pooled: false

And then using these attribute inject a ldaptemplate bean,this is a propeties class:

@ConfigurationProperties(prefix = "ldap")
public class LdapProperties {
private String url;
private String userDn;
private String password;
private String baseDN;
private String clean;
private String root;
private boolean pooled = false;
}

this is a Configuration class:

@Configuration
@EnableConfigurationProperties({LdapProperties.class})
public class LdapConfiguration {
@Autowired
LdapProperties ldapProperties;
@Bean
public LdapTemplate ldapTemplate() {
    LdapContextSource contextSource = new LdapContextSource();
    contextSource.setUrl(ldapProperties.getUrl());
    contextSource.setUserDn(ldapProperties.getUserDn());
    contextSource.setPassword(ldapProperties.getPassword());
    contextSource.setPooled(ldapProperties.getPooled());
    contextSource.setBase(ldapProperties.getBaseDN());
    contextSource.afterPropertiesSet();
    return new LdapTemplate(contextSource);
   }
   }

And then you can use @Autowired Annotations.This annotation allows Spring to resolve and inject collaborating beans into your bean.

    @Autowired
    LdapTemplate ldapTemplate;

Using ldapTemplate you could do CRUD like a relational database.of course you can do authentication things. This is my first time answer questions in stackoverflow,I welcome you to point out my mistakes.
