Spring Boot集成Ldap快速入门Demo

本文主要是介绍Spring Boot集成Ldap快速入门Demo，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

1.Ldap介绍

LDAP，Lightweight Directory Access Protocol，轻量级目录访问协议.

LDAP是一种特殊的服务器，可以存储数据
数据的存储是目录形式的，或者可以理解为树状结构（一层套一层）
一般存储关于用户、用户认证信息、组、用户成员，通常用于用户认证与授权

LDAP简称对应

o：organization（组织-公司）
ou：organization unit（组织单元-部门）
c：countryName（国家）
dc：domainComponent（域名）
sn：surname（姓氏）
cn：common name（常用名称）

2.环境搭建

docker-compose-ldap.yaml

version: '3'services:openldap:container_name: openldapimage: osixia/openldap:latestports:- "8389:389"- "8636:636"volumes:- ~/ldap/backup:/data/backup- ~/ldap/data:/var/lib/openldap- ~/ldap/config:/etc/openldap/slapd.d- ~/ldap/certs:/assets/slapd/certscommand: [--copy-service,  --loglevel, debug]phpldapadmin:container_name: phpldapadminimage: osixia/phpldapadmin:latestports:- "8080:80"environment:- PHPLDAPADMIN_HTTPS="false"- PHPLDAPADMIN_LDAP_HOSTS=openldaplinks:- openldapdepends_on:- openldap

ldap setup

docker-compose -f docker-compose-ldap.yml -p ldap up -d

open http://localhost:8080/

default account

username：cn=admin,dc=example,dc=org
password：admin

init data

dn: ou=people,dc=exapmple,dc=org
objectClass: top
objectClass: organizationalUnit
ou: people

3.代码工程

pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><parent><artifactId>springboot-demo</artifactId><groupId>com.et</groupId><version>1.0-SNAPSHOT</version></parent><modelVersion>4.0.0</modelVersion><artifactId>ldap</artifactId><properties><maven.compiler.source>8</maven.compiler.source><maven.compiler.target>8</maven.compiler.target></properties><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-autoconfigure</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency><!--ldap--><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-ldap</artifactId></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId></dependency></dependencies>
</project>

application.yaml


spring:application:name: spring-demo-ldap# ldap configurationldap:urls: ldap://127.0.0.1:8389base: dc=example,dc=orgusername: cn=admin,${spring.ldap.base}password: adminserver:port: 8088

Person.java

package com.et.ldap.entity;import lombok.Data;
import org.springframework.ldap.odm.annotations.Attribute;
import org.springframework.ldap.odm.annotations.DnAttribute;
import org.springframework.ldap.odm.annotations.Entry;
import org.springframework.ldap.odm.annotations.Id;import javax.naming.Name;
import java.io.Serializable;@Data
@Entry(base = "ou=people", objectClasses="inetOrgPerson")
public class Person implements Serializable {private static final long serialVersionUID = -337113594734127702L;/***neccesary*/@Idprivate Name id;@DnAttribute(value = "uid", index = 3)private String uid;@Attribute(name = "cn")private String commonName;@Attribute(name = "sn")private String suerName;private String userPassword;}

4.测试

运行单元测试类，查看数据，可以看到新增一个人
