Spring LDAP :: Apache Camel

URI format

spring-ldap:springLdapTemplate[?options]

Where springLdapTemplate is the name of the Spring LDAP Template bean. In this bean, you configure the URL and the credentials for your LDAP access.

Options

The Spring LDAP component supports 2 options, which are listed below.

Name	Description	Default	Type
lazyStartProducer (producer)	Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing.	false	boolean
basicPropertyBinding (advanced)	Deprecated Whether the component should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities	false	boolean

Usage

The component supports producer endpoint only. An attempt to create a consumer endpoint will result in an UnsupportedOperationException.
The body of the message must be a map (an instance of java.util.Map). Unless a base DN is specified by in the configuration of your ContextSource, this map must contain at least an entry with the key dn (not needed for function_driven operation) that specifies the root node for the LDAP operation to be performed. Other entries of the map are operation-specific (see below).

The body of the message remains unchanged for the bind and unbind operations. For the search and function_driven operations, the body is set to the result of the search, see http://static.springsource.org/spring-ldap/site/apidocs/org/springframework/ldap/core/LdapTemplate.html#search%28java.lang.String,%20java.lang.String,%20int,%20org.springframework.ldap.core.AttributesMapper%29.

Search

The message body must have an entry with the key filter. The value must be a String representing a valid LDAP filter, see http://en.wikipedia.org/wiki/Lightweight_Directory_Access_Protocol#Search_and_Compare.

Bind

The message body must have an entry with the key attributes. The value must be an instance of javax.naming.directory.Attributes This entry specifies the LDAP node to be created.

Unbind

No further entries necessary, the node with the specified dn is deleted.

Authenticate

The message body must have entries with the keys filter and password. The values must be an instance of String representing a valid LDAP filter and a user password, respectively.

Modify Attributes

The message body must have an entry with the key modificationItems. The value must be an instance of any array of type javax.naming.directory.ModificationItem

Function-Driven

The message body must have entries with the keys function and request. The function value must be of type java.util.function.BiFunction<L, Q, S>. The L type parameter must be of type org.springframework.ldap.core.LdapOperations. The request value must be the same type as the Q type parameter in the function and it must encapsulate the parameters expected by the LdapTemplate method being invoked within the function. The S type parameter represents the response type as returned by the LdapTemplate method being invoked. This operation allows dynamic invocation of LdapTemplate methods that are not covered by the operations mentioned above.

Key definitions

In order to avoid spelling errors, the following constants are defined in org.apache.camel.springldap.SpringLdapProducer:

public static final String DN = "dn"
public static final String FILTER = "filter"
public static final String ATTRIBUTES = "attributes"
public static final String PASSWORD = "password";
public static final String MODIFICATION_ITEMS = "modificationItems";
public static final String FUNCTION = "function";
public static final String REQUEST = "request";

Spring Boot Auto-Configuration

When using spring-ldap with Spring Boot make sure to use the following Maven dependency to have support for auto configuration:

<dependency>
  <groupId>org.apache.camel.springboot</groupId>
  <artifactId>camel-spring-ldap-starter</artifactId>
  <version>x.x.x</version>
  <!-- use the same version as your Camel core version -->
</dependency>

The component supports 3 options, which are listed below.

Name	Description	Default	Type
camel.component.spring-ldap.autowired-enabled	Whether autowiring is enabled. This is used for automatic autowiring options (the option must be marked as autowired) by looking up in the registry to find if there is a single instance of matching type, which then gets configured on the component. This can be used for automatic configuring JDBC data sources, JMS connection factories, AWS Clients, etc.	true	Boolean
camel.component.spring-ldap.enabled	Whether to enable auto configuration of the spring-ldap component. This is enabled by default.		Boolean
camel.component.spring-ldap.lazy-start-producer	Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers.
