本範例為Spring官方教學Authenticating a User with LDAP的實作。
範例環境如下：
- macOS High Sierra
- Java 1.8
- Eclipse for Java EE 2019-06 (4.12.0)
- Spring Boot 2.1.8.RELEASE
- Eclipse Gradle Buildship plug-in
建立一個Spring Boot Gradle專案，專案進入點的SprinBootApplication類如下。
SpringSecurityLdapDemoApplication
package com.abc.demo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class SpringSecurityLdapDemoApplication {
public static void main(String[] args) {
SpringApplication.run(SpringSecurityLdapDemoApplication.class, args);
}
}
在專案的Gradle配置檔build.bradle加入以下dependencies。
implementation 'org.springframework.boot:spring-boot-starter-web' // Spring Web
implementation 'org.springframework.boot:spring-boot-starter-security' // Spring Security
implementation 'org.springframework.security:spring-security-ldap' // Spring Security LDAP
implementation 'org.springframework.boot:spring-boot-starter-data-ldap' // Spring Data LDAP
implementation 'com.unboundid:unboundid-ldapsdk' // In-Memory Directory Server
設定好後專案的build.gralde內容如下：
build.gradle
plugins {
id 'org.springframework.boot' version '2.1.8.RELEASE'
id 'io.spring.dependency-management' version '1.0.8.RELEASE'
id 'java'
}
group = 'com.abc.demo'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '1.8'
repositories {
mavenCentral()
}
dependencies {
implementation 'org.springframework.boot:spring-boot-starter-web'
implementation 'org.springframework.boot:spring-boot-starter-security'
implementation 'org.springframework.security:spring-security-ldap'
implementation 'org.springframework.boot:spring-boot-starter-data-ldap'
implementation 'com.unboundid:unboundid-ldapsdk'
testImplementation 'org.springframework.boot:spring-boot-starter-test'
testImplementation 'org.springframework.security:spring-security-test'
}
在Spring Boot配置檔application.properties新增以下embedded LDAP Server參數(EmbeddedLdapProperties)的配置。
application.properties
#LDAP人員資料來源位置
spring.ldap.embedded.ldif=classpath:test-server.ldif
#LDAP base dn
spring.ldap.embedded.base-dn=dc=springframework,dc=org
#LDAP Server port
spring.ldap.embedded.port=8389
在專案的用來擺放靜態資源的src/main/resources路徑下新增存放embedded LDAP Server的人員資料的test-server.ldif檔。
test-server.ldif

objectclass: top
objectclass: groupOfUniqueNames
cn: submanagers
ou: submanager
uniqueMember: uid=ben,ou=people,dc=springframework,dc=org
在專案新增Spring Security的配置類別WebSecurityConfig如下。
LdapWebSecurityConfig
package com.abc.demo.config;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.crypto.password.LdapShaPasswordEncoder;
@EnableWebSecurity
public class LdapWebSecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception
{
http.authorizeRequests().anyRequest().fullyAuthenticated().and().formLogin();
}
@Override
public void configure(AuthenticationManagerBuilder auth) throws Exception
{
auth.ldapAuthentication()
.userDnPatterns("uid={0},ou=people")
.groupSearchBase("ou=groups")
.contextSource()
.url("ldap://localhost:8389/dc=springframework,dc=org")
.and()
.passwordCompare()
.passwordEncoder(new LdapShaPasswordEncoder())
.passwordAttribute("userPassword");
}
}
新增通過驗證後導向的DemoController。
package com.abc.demo.controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class DemoController {
@GetMapping("/")
public String index() {
return "Welcome to the home page!";
}
}
範例的專案目錄結構如下。
設定完後啟動專案，然後在瀏覽器輸入http://localhost:8080便會進入Spring Security的登入畫面。
輸入test-server.ldif中的人員帳號密碼，例如bob/bobspassword登入。
如果通過驗證便會導向DemoController並返回結果如下。
只能説Spring官方教學通常都寫得太簡單，有些設定都沒寫清楚常跑不起來，還要去官方範例的github連結看一下是否少了東西。
