好的,以下是Spring Boot使用Spring security集成CAS的详细代码:
1. 添加依赖
在`pom.xml`文件中添加以下依赖:
```xml
<!-- Spring Security CAS Client -->
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-cas</artifactId>
<version>5.3.1.RELEASE</version>
</dependency>
<!-- Spring Security Web -->
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-web</artifactId>
<version>5.3.1.RELEASE</version>
</dependency>
<!-- Spring Security Config -->
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-config</artifactId>
<version>5.3.1.RELEASE</version>
</dependency>
<!-- Spring Security Core -->
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-core</artifactId>
<version>5.3.1.RELEASE</version>
</dependency>
```
2. 配置CAS服务端信息
在`application.properties`文件中配置CAS服务端信息:
```properties
# CAS Server URL
cas.server.url=https://cas.example.com:8443/cas
# CAS Server Login URL
cas.server.login.url=https://cas.example.com:8443/cas/login
# CAS Server Logout URL
cas.server.logout.url=https://cas.example.com:8443/cas/logout
# CAS Server Validation URL
cas.server.validation.url=https://cas.example.com:8443/cas/serviceValidate
```
3. 配置Spring Security
创建一个`WebSecurityConfig`类,并在其中配置Spring Security:
```java
@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
private Environment env;
@Override
protected void configure(HttpSecurity http) throws Exception {
http
.authorizeRequests()
.antMatchers("/login**").permitAll()
.anyRequest().authenticated()
.and()
.logout()
.logoutUrl("/logout")
.logoutSuccessUrl("/")
.invalidateHttpSession(true)
.deleteCookies("JSESSIONID")
.and()
.apply(new CasAuthenticationConfigurer<>(casAuthenticationProvider()));
}
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.authenticationProvider(casAuthenticationProvider());
}
@Bean
public AuthenticationProvider casAuthenticationProvider() {
CasAuthenticationProvider provider = new CasAuthenticationProvider();
provider.setServiceProperties(serviceProperties());
provider.setTicketValidator(cas30ServiceTicketValidator());
provider.setUserDetailsService(userDetailsService());
provider.setKey(env.getProperty("cas.key"));
return provider;
}
@Bean
public ServiceProperties serviceProperties() {
ServiceProperties serviceProperties = new ServiceProperties();
serviceProperties.setService(env.getProperty("cas.service"));
serviceProperties.setAuthenticateAllArtifacts(true);
return serviceProperties;
}
@Bean
public Cas30ServiceTicketValidator cas30ServiceTicketValidator() {
return new Cas30ServiceTicketValidator(env.getProperty("cas.server.url"));
}
@Bean
public UserDetailsServiceImpl userDetailsService() {
return new UserDetailsServiceImpl();
}
}
```
4. 实现用户认证
创建一个`UserDetailsServiceImpl`类,实现用户认证:
```java
@Service
public class UserDetailsServiceImpl implements UserDetailsService {
@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
// 根据用户名查询用户信息,并返回一个UserDetails对象
return new User(username, "", new ArrayList<>());
}
}
```
5. 编写登录页面
在`templates`目录下创建一个`login.html`文件,编写登录页面:
```html
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Login</title>
</head>
<body>
<h1>Login</h1>
<form method="post" action="/login/cas">
<input type="submit" value="Login with CAS">
</form>
</body>
</html>
```
6. 启动应用程序
运行应用程序,并访问登录页面。点击“Login with CAS”按钮,将跳转到CAS登录页面。登录成功后,将返回到应用程序,并显示用户信息。
这就是Spring Boot使用Spring security集成CAS的详细代码。其中,`WebSecurityConfig`类是Spring Security的配置类,`UserDetailsServiceImpl`类是用户认证的实现类,`login.html`文件是登录页面的模板。
