很抱歉,我是AI语言模型,无法上传代码,但是我可以给你提供一个简单的Spring Security OAuth2实现认证的步骤:
1. 添加依赖
在pom.xml中添加以下依赖:
```xml
<dependency>
<groupId>org.springframework.security.oauth</groupId>
<artifactId>spring-security-oauth2</artifactId>
<version>2.4.1</version>
</dependency>
```
2. 配置OAuth2认证服务器
创建一个OAuth2认证服务器的配置类,并实现AuthorizationServerConfigurer接口。在configure(ClientDetailsServiceConfigurer clients)方法中配置客户端详情服务,包括client_id, client_secret, authorized_grant_types, scopes等信息。
```java
@Configuration
@EnableAuthorizationServer
public class OAuth2AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {
@Autowired
private AuthenticationManager authenticationManager;
@Autowired
private UserDetailsService userDetailsService;
@Autowired
private DataSource dataSource;
@Override
public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
clients.jdbc(dataSource);
}
@Override
public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
endpoints.authenticationManager(authenticationManager)
.userDetailsService(userDetailsService);
}
}
```
3. 配置资源服务器
创建一个资源服务器的配置类,并实现ResourceServerConfigurer接口。在configure(HttpSecurity http)方法中配置资源服务器的安全策略,包括允许访问的URL,需要认证的URL等信息。
```java
@Configuration
@EnableResourceServer
public class OAuth2ResourceServerConfig extends ResourceServerConfigurerAdapter {
@Override
public void configure(HttpSecurity http) throws Exception {
http.authorizeRequests()
.antMatchers("/api/**").authenticated()
.anyRequest().permitAll();
}
}
```
4. 配置Spring Security
在Spring Security的配置类中,配置OAuth2的安全策略。在configure(HttpSecurity http)方法中,配置请求的安全策略,包括需要认证的URL,允许访问的URL等信息。
```java
@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests()
.antMatchers("/login").permitAll()
.anyRequest().authenticated()
.and()
.formLogin().loginPage("/login").permitAll()
.and()
.logout().logoutSuccessUrl("/login").permitAll();
}
@Override
@Bean
public AuthenticationManager authenticationManagerBean() throws Exception {
return super.authenticationManagerBean();
}
@Override
@Bean
public UserDetailsService userDetailsServiceBean() throws Exception {
return super.userDetailsServiceBean();
}
@Bean
public PasswordEncoder passwordEncoder() {
return new BCryptPasswordEncoder();
}
}
```
以上是Spring Security OAuth2实现认证的简单步骤,具体的代码实现根据自己的需求进行修改。
