  • SpringSecurity初步理解

    Authenticating a User with LDAP

    首先创建一个简单的web控制器

     1 package hello;
 2 
 3 import org.springframework.web.bind.annotation.GetMapping;
 4 import org.springframework.web.bind.annotation.RestController;
 5 
 6 @RestController
 7 public class HomeController {
 8 
 9     @GetMapping("/")
10     public String index() {
11         return "Welcome to the home page!";
12     }
13 }

    老生常谈，用到springboot，肯定少不了它的启动类

    package hello;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

}

    SpringSecurity需要用到的maven依赖如下图

    <dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-security</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.ldap</groupId>
        <artifactId>spring-ldap-core</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.security</groupId>
        <artifactId>spring-security-ldap</artifactId>
    </dependency>
    <dependency>
        <groupId>com.unboundid</groupId>
        <artifactId>unboundid-ldapsdk</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>org.springframework.security</groupId>
        <artifactId>spring-security-test</artifactId>
        <scope>test</scope>
    </dependency>
</dependencies>

    开始做详细的安全认证，安全认证的思路是这样的“

    创建一个类并继承WebSecurityConfigurerAdapter这个方法，并在之类中重写configure的3个方法，
    其中3个方法中参数包括为
    HttpSecurity（HTTP请求安全处理），AuthenticationManagerBuilder（身份验证管理生成器）和WebSecurity（WEB安全）。

    如下代码
     1 package com.ssm.demo.com.ssm.Hello;
 2 
 3 import org.springframework.context.annotation.ComponentScan;
 4 import org.springframework.context.annotation.Configuration;
 5 import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
 6 import org.springframework.security.config.annotation.web.builders.HttpSecurity;
 7 import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
 8 import org.springframework.security.crypto.password.LdapShaPasswordEncoder;
 9 /**
10  *
11  创建一个类并继承WebSecurityConfigurerAdapter这个方法，并在之类中重写configure的3个方法，
12  其中3个方法中参数包括为
13  HttpSecurity（HTTP请求安全处理），AuthenticationManagerBuilder（身份验证管理生成器）和WebSecurity（WEB安全）。
14  */
15 @Configuration
16 @ComponentScan
17 public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
18     /**
19      * http请求安全处理
20      * @param http
21      * @throws Exception
22      */
23     @Override
24     protected void configure(HttpSecurity http) throws Exception {
25         //http.authorizeRequests()这里的意思是通过方法来开始请求权限配置，
26         //fullyAuthenticated()意为用户完全认证可以访问
27         //and()是返回一个securityBuilder对象，formLogin()和httpBasic()是授权的两种方式
28         http.authorizeRequests().anyRequest().fullyAuthenticated().and().formLogin();
29     }
30 
31     /**
32      * 身份验证管理生成器
33      * @param auth
34      * @throws Exception
35      */
36     @Override
37     protected void configure(AuthenticationManagerBuilder auth) throws Exception {
38         auth.ldapAuthentication().userDnPatterns("uid={0},ou=people").groupSearchBase("ou=groups").contextSource().
39                 url("ldap://localhost:8389/dc=springframework,dc=org").and().passwordCompare().passwordEncoder(new LdapShaPasswordEncoder())
40                 .passwordAttribute("userPassword");
41     }
42 }

    设置用户数据，使用到LDAP服务器（ldif文件），

    在yml中添加LDAP服务的代理

    server:
  servlet:
    context-path: /llh
  port: 8082
spring:
  datasource:
    url: jdbc:mysql://127.0.0.1:3306/depot?useUnicode=true&characterEncoding=utf8
    username: root
    password: 123456
  servlet:
    multipart:
      max-file-size: 128KB
      max-request-size: 128KB
  ldap:
    embedded:
      ldif: classpath:test-server.ldif
      base-dn: dc=springframework,dc=org
      port: 8389

    resource文件夹下面创建一个test-server.ldif文件

      1 dn: dc=springframework,dc=org

    这时候就可以启动springboot的启动类，键入地址：http://127.0.0.1:8082/llh/，发现已经被拦截下来了，并且重定向到了Spring Security提供的登录页面

    ，见下图：

    输入用户名：ben，密码：benspassword，即可登录。
