springboot前后端分离集成CAS单点登录(统一认证)
在Spring Boot中实现前后端分离的CAS单点登录,你需要做以下几个步骤:
- 引入CAS客户端依赖
- 配置CAS客户端
- 创建CAS认证成功的Controller处理登录请求
- 配置Spring Security以使用CAS
以下是一个简化的示例:
步骤1:引入CAS客户端依赖
在pom.xml
中添加CAS客户端依赖,如cas-client-autoconfig-support
:
<dependency>
<groupId>org.jasig.cas.client</groupId>
<artifactId>cas-client-autoconfig-support</artifactId>
<version>版本号</version>
</dependency>
步骤2:配置CAS客户端
在application.properties
或application.yml
中配置CAS服务器的地址、服务地址等信息:
# CAS服务器URL
cas.server-url-prefix=https://yourcas.server.com/cas
# CAS服务登录URL
cas.server-login-url=https://yourcas.server.com/cas/login
# 应用的服务地址
cas.service-url-base=http://localhost:8080/
步骤3:创建Controller处理登录请求
创建一个Controller来处理登录成功后的请求:
@Controller
public class LoginController {
@RequestMapping("/login")
public String login() {
return "redirect:/cas-login";
}
@RequestMapping("/cas-login")
public String casLogin() {
return "casLogin";
}
@RequestMapping("/logout")
public String logout(HttpSession session) {
session.invalidate();
return "redirect:/cas-logout";
}
}
步骤4:配置Spring Security
配置Spring Security以使用CAS,并处理登录成功和登出:
@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
private AuthenticationEntryPoint authenticationEntryPoint;
@Autowired
private ServiceProperties serviceProperties;
@Override
protected void configure(HttpSecurity http) throws Exception {
http
.authorizeRequests()
.anyRequest().authenticated()
.and()
.exceptionHandling()
.authenticationEntryPoint(authenticationEntryPoint)
.and()
.logout()
.logoutUrl("/logout")
.deleteCookies("JSESSIONID")
.invalidateHttpSession(true)
.and()
.csrf()
.disable();
}
@Bean
public Filter casAuthenticationFilter() throws Exception {
CasAuthenticationFilter filter = new CasAuthenticationFilter();
filter.setAuthenticationManager(authenticationManager());
filter.setServiceProperties(serviceProperties);
return filter;
}
// 其他的配置如AuthenticationManager、AuthenticationProvider等
}
