springcloud用户认证的代码

由于Spring Cloud提供了多个用户认证解决方案,因此代码会根据具体的方案而有所不同。以下是一些常见的Spring Cloud用户认证方案及其代码示例:
1. 基于Spring Security的用户认证
添加依赖:
```xml
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-security</artifactId>
</dependency>
```
配置:
```java
@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests()
.antMatchers("/api/**").authenticated()
.anyRequest().permitAll()
.and()
.formLogin()
.and()
.httpBasic();
}
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.inMemoryAuthentication()
.withUser("user")
.password("{noop}password")
.roles("USER");
}
}
```
上述代码中,我们使用了基于内存的用户认证方式。在实际的生产环境中,我们通常会使用基于数据库的用户认证方式。
2. 基于OAuth 2.0的用户认证
添加依赖:
```xml
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-oauth2</artifactId>
</dependency>
```
配置:
```java
@Configuration
@EnableAuthorizationServer
public class AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {
@Autowired
private AuthenticationManager authenticationManager;
@Override
public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
clients.inMemory()
.withClient("client")
.secret("{noop}secret")
.authorizedGrantTypes("password", "refresh_token")
.scopes("read", "write")
.accessTokenValiditySeconds(3600)
.refreshTokenValiditySeconds(86400);
}
@Override
public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
endpoints.authenticationManager(authenticationManager);
}
}
@Configuration
@EnableResourceServer
public class ResourceServerConfig extends ResourceServerConfigurerAdapter {
@Override
public void configure(HttpSecurity http) throws Exception {
http.authorizeRequests()
.antMatchers("/api/**").authenticated()
.anyRequest().permitAll();
}
}
```
上述代码中,我们使用了OAuth 2.0的密码模式作为认证方式。在实际的生产环境中,我们通常会使用更为安全的授权码模式或者客户端模式。
