关于“springboot集成CAS实现单点登录的示例代码”的完整攻略,我将为您详细讲解,包括以下几个步骤:
- 添加依赖
使用SpringBoot集成CAS需要添加cas-client-support-spring-boot-starter依赖。例如:
<dependency>
<groupId>org.apereo.cas</groupId>
<artifactId>cas-client-support-spring-boot-starter</artifactId>
<version>${cas.version}</version>
</dependency>
其中${cas.version}需要根据实际情况替换为CAS的版本号。
- 配置CAS客户端
在SpringBoot的application.yml或application.properties中添加CAS客户端的配置,例如:
cas:
server-url-prefix: https://cas.example.org
server-login-url: https://cas.example.org/login
client-host-url: http://localhost:8080
其中cas.server-url-prefix为CAS服务器的地址,cas.server-login-url为CAS登录页面的地址(一般为https://cas.example.org/login),cas.client-host-url为CAS客户端的地址。
- 配置CAS过滤器
在SpringBoot的配置类中添加CAS过滤器,例如:
@Bean
public FilterRegistrationBean<Cas20ProxyReceivingTicketValidationFilter> filterRegistrationBean() {
FilterRegistrationBean<Cas20ProxyReceivingTicketValidationFilter> registrationBean = new FilterRegistrationBean<>();
registrationBean.setFilter(new Cas20ProxyReceivingTicketValidationFilter());
registrationBean.addUrlPatterns("/*");
registrationBean.addInitParameter("casServerUrlPrefix", casServerUrlPrefix);
registrationBean.addInitParameter("serverName", serverName);
return registrationBean;
}
其中casServerUrlPrefix为CAS服务器的地址,serverName为CAS客户端的地址。
- 实现CAS用户信息查询接口
CAS客户端需要查询CAS服务器中的用户信息,需要实现接口org.jasig.cas.client.authentication.AttributePrincipal来获取用户信息,例如:
@Service
public class UserDataServiceImpl implements UserDataService {
@Override
public Map<String, Object> getUserData(AttributePrincipal attributePrincipal) {
Map<String, Object> userData = new HashMap<>();
if (attributePrincipal != null) {
String username = attributePrincipal.getName();
userData.put("username", username);
Map<String, Object> attributes = attributePrincipal.getAttributes();
if (attributes != null && !attributes.isEmpty()) {
userData.putAll(attributes);
}
}
return userData;
}
}
- 实现CAS用户信息获取接口
控制器中提供获取CAS用户信息的接口,例如:
@RestController
@RequestMapping("/user")
public class UserController {
@Autowired
private UserDataService userDataService;
@GetMapping("/info")
public Map<String, Object> getUserInfo(HttpServletRequest request) {
AttributePrincipal attributePrincipal = (AttributePrincipal) request.getUserPrincipal();
return userDataService.getUserData(attributePrincipal);
}
}
上述代码是实现Springboot集成CAS实现单点登录的示例,下面再给出一份集成SpringSecurity的示例代码:
- 添加依赖
使用SpringSecurity集成CAS需要添加spring-security-cas依赖。例如:
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-cas</artifactId>
<version>${spring-security.version}</version>
</dependency>
其中${spring-security.version}需要根据实际情况替换为SpringSecurity的版本号。
- 配置CAS客户端
在SpringBoot的application.yml或application.properties中添加CAS客户端的配置,例如:
cas:
server-url-prefix: https://cas.example.org
server-login-url: https://cas.example.org/login
client-host-url: http://localhost:8080
其中cas.server-url-prefix为CAS服务器的地址,cas.server-login-url为CAS登录页面的地址(一般为https://cas.example.org/login),cas.client-host-url为CAS客户端的地址。
- 配置SpringSecurity
在SpringBoot的配置类中添加SpringSecurity配置,例如:
@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests()
.antMatchers("/**")
.authenticated()
.and()
.casLogin()
.loginUrl("https://cas.example.org/login")
.and()
.logout()
.logoutUrl("/logout")
.logoutSuccessUrl("/")
.invalidateHttpSession(true)
.deleteCookies("JSESSIONID")
.and()
.csrf().disable();
}
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.authenticationProvider(casAuthenticationProvider());
}
@Bean
public CasAuthenticationProvider casAuthenticationProvider() {
CasAuthenticationProvider provider = new CasAuthenticationProvider();
provider.setServiceProperties(serviceProperties());
provider.setTicketValidator(cas20ServiceTicketValidator());
provider.setUserDetailsService(userDetailsService());
provider.setKey("casAuthProviderKey");
return provider;
}
@Bean
public UserDetailsService userDetailsService() {
return new InMemoryUserDetailsManager(Collections.singletonList(new User("admin", "{noop}admin", Collections.singletonList(new SimpleGrantedAuthority("ROLE_ADMIN")))));
}
@Bean
public ServiceProperties serviceProperties() {
ServiceProperties serviceProperties = new ServiceProperties();
serviceProperties.setService("http://localhost:8080/login/cas");
serviceProperties.setSendRenew(false);
return serviceProperties;
}
@Bean
public Cas20ServiceTicketValidator cas20ServiceTicketValidator() {
return new Cas20ServiceTicketValidator("https://cas.example.org");
}
}
- 实现控制器
控制器中提供CAS用户信息获取的接口,例如:
@RestController
@RequestMapping("/user")
public class UserController {
@Autowired
private UserDataService userDataService;
@GetMapping("/info")
public Map<String, Object> getUserInfo(HttpServletRequest request) {
Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
if (authentication instanceof CasAuthenticationToken) {
CasAuthenticationToken casAuthenticationToken = (CasAuthenticationToken) authentication;
AttributePrincipal attributePrincipal = casAuthenticationToken.getAssertion().getPrincipal();
return userDataService.getUserData(attributePrincipal);
} else {
return null;
}
}
}
