好的,以下是一个简单的OAuth 2.0授权码认证的Java实例:
首先,需要引入Maven依赖,包括Spring Security OAuth2和Spring Web MVC:
```xml
<dependency>
<groupId>org.springframework.security.oauth</groupId>
<artifactId>spring-security-oauth2</artifactId>
<version>2.3.6.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>5.3.8</version>
</dependency>
```
接着,创建一个`WebSecurityConfigurerAdapter`类,用于配置Spring Security:
```java
@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
private UserDetailsService userDetailsService;
@Bean
public PasswordEncoder passwordEncoder() {
return new BCryptPasswordEncoder();
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests()
.antMatchers("/oauth/**").permitAll()
.anyRequest().authenticated()
.and().formLogin().permitAll();
}
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(userDetailsService).passwordEncoder(passwordEncoder());
}
}
```
在上面的代码中,我们配置了允许所有用户访问`/oauth/**`路径下的资源,其他路径需要进行身份验证,使用BCrypt密码编码器进行密码加密。
接着,创建一个`AuthorizationServerConfigurerAdapter`类,用于配置OAuth2认证服务器:
```java
@Configuration
@EnableAuthorizationServer
public class AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {
@Autowired
private AuthenticationManager authenticationManager;
@Autowired
private UserDetailsService userDetailsService;
@Autowired
private DataSource dataSource;
@Bean
public TokenStore tokenStore() {
return new JdbcTokenStore(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)
.tokenStore(tokenStore());
}
}
```
在上面的代码中,我们配置了使用JDBC进行令牌存储,并使用数据源配置客户端详情服务。
最后,创建一个`ResourceServerConfigurerAdapter`类,用于配置OAuth2资源服务器:
```java
@Configuration
@EnableResourceServer
public class ResourceServerConfig extends ResourceServerConfigurerAdapter {
@Override
public void configure(HttpSecurity http) throws Exception {
http.authorizeRequests()
.antMatchers("/api/**").authenticated()
.anyRequest().permitAll();
}
}
```
在上面的代码中,我们配置了只允许经过身份验证的用户访问`/api/**`路径下的资源。
以上是一个简单的OAuth 2.0授权码认证的Java实例。
