SpringBoot2 MyBatis如何集成LDAP认证

发布时间:2024-11-05 16:01:30 来源:亿速云 阅读:84 作者:小樊 栏目:编程语言

要在Spring Boot 2中集成MyBatis进行LDAP认证,请按照以下步骤操作:

  1. 添加依赖

pom.xml文件中添加Spring Boot和MyBatis的依赖:

<dependencies>
    <!-- Spring Boot Starter Web -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>

    <!-- Spring Boot Starter Data JPA -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jpa</artifactId>
    </dependency>

    <!-- MyBatis Starter -->
    <dependency>
        <groupId>org.mybatis.spring.boot</groupId>
        <artifactId>mybatis-spring-boot-starter</artifactId>
        <version>2.1.4</version>
    </dependency>

    <!-- LDAP Authentication -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-security</artifactId>
    </dependency>

    <!-- Apache Directory LDAP API -->
    <dependency>
        <groupId>org.apache.directory.api</groupId>
        <artifactId>api-all</artifactId>
        <version>2.0.0.AM25</version>
    </dependency>
</dependencies>
  1. 配置LDAP

application.propertiesapplication.yml文件中配置LDAP连接信息:

# application.properties
spring.ldap.urls=ldap://localhost:389
spring.ldap.base=ou=users,dc=example,dc=com
spring.ldap.username=cn=admin,dc=example,dc=com
spring.ldap.password=secret
spring.ldap.search-filter=uid={0}

# application.yml
spring:
  ldap:
    urls: ldap://localhost:389
    base: ou=users,dc=example,dc=com
    username: cn=admin,dc=example,dc=com
    password: secret
    search-filter: uid={0}
  1. 创建LDAP配置类

创建一个配置类,用于配置LDAP认证和授权:

import org.apache.directory.api.ldap.model.cursor.CursorException;
import org.apache.directory.api.ldap.model.entry.DefaultEntry;
import org.apache.directory.api.ldap.model.entry.Entry;
import org.apache.directory.api.ldap.model.entry.EntryUtils;
import org.apache.directory.api.ldap.model.exception.LdapAuthenticationException;
import org.apache.directory.api.ldap.model.exception.LdapException;
import org.apache.directory.api.ldap.model.name.Dn;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.authentication.AuthenticationProvider;
import org.springframework.security.authentication.BadCredentialsException;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.AuthenticationException;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.security.ldap.authentication.LdapAuthenticationProvider;
import org.springframework.security.ldap.search.FilterBasedLdapUserSearch;
import org.springframework.security.ldap.userdetails.LdapUserDetailsMapper;

@Configuration
public class LdapConfig {

    @Autowired
    private LdapProperties ldapProperties;

    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }

    @Bean
    public AuthenticationProvider ldapAuthenticationProvider(PasswordEncoder passwordEncoder) throws Exception {
        LdapAuthenticationProvider provider = new LdapAuthenticationProvider();
        provider.setUrl(ldapProperties.getUrls());
        provider.setBase(new Dn(ldapProperties.getBase()));
        provider.setUsername(ldapProperties.getUsername());
        provider.setPassword(ldapProperties.getPassword());

        FilterBasedLdapUserSearch userSearch = new FilterBasedLdapUserSearch(
                new Dn(ldapProperties.getBase()), ldapProperties.getSearchFilter(), null);
        provider.setUserSearch(userSearch);

        LdapUserDetailsMapper userDetailsMapper = new LdapUserDetailsMapper() {
            @Override
            public UserDetails mapUserFromEntry(Entry entry) {
                return new User(entry.getDn().toString(), entry.getAttributes().get("userPassword").get().toString(), getAuthorities(entry));
            }

            @Override
            public List<GrantedAuthority> getAuthorities(Entry entry) {
                List<GrantedAuthority> authorities = new ArrayList<>();
                // 获取用户角色并转换为GrantedAuthority对象
                return authorities;
            }
        };
        provider.setUserDetailsMapper(userDetailsMapper);

        return provider;
    }
}
  1. 配置Spring Security

创建一个配置类,用于配置Spring Security和LDAP认证:

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
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.PasswordEncoder;
import org.springframework.security.ldap.authentication.LdapAuthenticationProvider;

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private LdapAuthenticationProvider ldapAuthenticationProvider;

    @Autowired
    private PasswordEncoder passwordEncoder;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .authorizeRequests()
                .anyRequest().authenticated()
                .and()
            .formLogin()
                .loginPage("/login")
                .permitAll()
                .and()
            .logout()
                .permitAll();
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.authenticationProvider(ldapAuthenticationProvider);
    }

    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }
}
  1. 创建登录页面

创建一个简单的登录页面(例如login.html),用于用户输入用户名和密码进行认证:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Login</title>
</head>
<body>
    <h1>Login</h1>
    <form action="/login" method="post">
        <label for="username">Username:</label>
        <input type="text" id="username" name="username" required>
        <br>
        <label for="password">Password:</label>
        <input type="password" id="password" name="password" required>
        <br>
        <button type="submit">Login</button>
    </form>
</body>
</html>

现在,当用户尝试访问受保护的资源时,将被重定向到登录页面。用户需要输入有效的LDAP用户名和密码进行认证。认证成功后,用户将被重定向回原来请求的资源。
